The previous piece showed how Iran and the Strait of Hormuz, oil prices, US inflation, Japan’s inflation, the BOJ, US long-term yields, and the global discount rate are all bound together in a single cycle. This piece addresses the next question: when and how can this cycle stabilize?

The US 10-year yield has been approaching 4.6%, and the 30-year has crossed 5%. Japan’s 10-year yield is at its highest since 1997. A simultaneous spike in long-term yields across both countries is not a common event. One can read this as a simple bond-market seizure, or as the beginning of something more structural.

My judgment lies in between. A short-term stabilization is possible. But this is not a market that unwinds on its own. What matters is how many of the following converge simultaneously: Hormuz normalization, oil prices, US inflation, BOJ guidance, and demand at US Treasury auctions.

Key Summary

Current state: US 10-year at 4.46%, 30-year at 5.02%, Japan 10-year at 2.55% (highest since 1997), Japan 30-year near 4.0%.
Decomposing the drivers: This is not simply a product of hawkish Fed commentary. Expected short-term rates, inflation premiums, term premiums, and bond supply premiums have all moved higher simultaneously.
Stabilization potential: Possible, but conditional. The structure does not unwind automatically over time.
Five core triggers: Hormuz normalization and falling oil prices; containment of energy pass-through into US core CPI/PPI; BOJ June meeting guidance; recovery in demand at 10-year and 30-year US Treasury auctions; flight-to-safety flows triggered by risk-asset corrections.
1-to-3-month scenarios: Fast stabilization 20–25%, range-bound consolidation 45–50%, renewed seizure 25–30%.
Single most important variable: Hormuz transit normalization. This one variable touches US inflation and Japan import prices simultaneously.
Investment judgment: It is premature to place a large bet on stabilization in advance. A staged entry after two to three of the five triggers are confirmed is more defensible.

1. Where We Stand Now

Between May 14 and 15, long-term yields moved higher again. The US 10-year yield climbed from 4.46% toward 4.60%, and the 30-year surged from 5.02% to as high as 5.13%. The May 30-year auction saw weak demand, with the stop-through rate coming in higher than market expectations and the tail widening.

Japan followed the same path. The 10-year JGB yield rose into the 2.55%–2.72% range, touching the highest level since 1997. The 30-year JGB approached 4.0%, and the 40-year had already traded as high as 4.24% back in January.

This is not a US-only problem. Long-end yields in Japan, Europe, and the US are all moving together. The global discount rate for risk assets is rising in unison — which explains why Korean equities, US mega-cap tech, KOSDAQ growth names, and long-duration bond ETFs are all under simultaneous pressure.

Why This Is Not a Simple Fed Hawkishness Event

Long-term yields are best understood as the sum of four components.

Component	Current direction	Implication
Expected short-rate path	Higher	Fed rate-cut expectations have faded; BOJ hike probability has risen
Inflation premium	Higher	US CPI, US PPI, and Japan PPI have all re-accelerated simultaneously
Term premium	Higher	The compensation demanded for holding long-duration paper has increased
Bond supply premium	Higher	Weak US auction demand and diminished Japanese marginal buying of Treasuries are compounding

In the US, virtually all Fed rate-cut expectations have evaporated, and markets have even begun pricing a December rate hike. In Japan, the probability of a BOJ June hike has risen above 70%. US April CPI came in at +3.8% year-over-year; Japan April PPI at +4.9%. The NY Fed ACM model puts the US term premium at 0.68% — still below the historical median of 1.47%, but the direction is toward normalization.

Supply-demand dynamics are equally unfavorable. The US must absorb roughly $2 trillion in annual fiscal deficits alongside large Treasury maturities. As BOJ normalization pushes JGB yields higher, the hedged return on US Treasuries for Japanese insurers and pension funds has declined. China, too, is no longer a consistent large buyer of Treasuries.

For yields to stabilize, improving one factor is not sufficient. If oil prices fall but the BOJ remains hawkish, Japan-sourced pressure persists. If the Fed turns more accommodative but auctions keep coming in weak, the long end of the US curve will continue to struggle.

Why the US and Japan Are Moving Together

The first linkage is a common shock. The Hormuz bottleneck and rising oil prices push US CPI and Japan import prices higher at the same time — through gasoline and energy services in the US, and through imported raw materials and corporate goods prices in Japan. This channel is the strongest.

The second linkage is Japanese capital flows. When JGB yields rise, the hedge-adjusted yield on US Treasuries becomes less attractive to Japanese insurers and pension funds. They do not need to sell Treasuries outright. Even a reduction in new purchases weakens the marginal demand for US Treasuries and pushes long-term yields higher.

The third linkage is a global re-pricing of sovereign bond risk. Watching a country like Japan — with an extremely high government debt load — see its 10-year yield move from 2% to 3% territory raises questions about appropriate term premiums for other developed-market sovereigns: the US, Canada, Italy. Markets have started asking those questions again.

Of these three channels, the first — Hormuz and oil prices — is the most powerful. Which is why the central question in this piece ultimately returns to whether Hormuz normalizes.

2. Five Core Triggers

2.1 Hormuz Normalization and Lower Oil Prices

The most powerful trigger is Hormuz normalization. The reason is straightforward: oil prices affect US and Japanese inflation simultaneously.

A substantial portion of the US April CPI print of +3.8% came from energy. Gasoline prices and energy services pushed the headline directly higher. Japan’s exposure is even more direct. The backbone of Japan’s April PPI of +4.9% was import prices rising +17.5%, dominated by energy and raw materials.

If Hormuz transit normalizes and Brent crude stabilizes below $95 for at least one week, the probability that US and Japanese yields ease simultaneously rises meaningfully. Conversely, if Brent re-breaks above $110 and vessel attacks or seizures recur, the long-yield shock can re-intensify.

Category	Stabilization signal	Deterioration signal
Oil price	Brent stable below $95	Re-breaks $110
Hormuz	Vessel traffic recovers to 70%+ of normal	Additional attacks or seizures
Inventories	IEA/EIA draw rate decelerates	Continued draws above 5 mb/day average
War risk insurance	Rates normalize	Vessel war-risk premiums remain at 2–3%
Negotiations	Iran–US talks show progress	Reported collapse of talks

I assess the probability of near-term full normalization at 25–30%. Partial normalization is the most likely outcome at 45–50%, and prolonged disruption sits at 20–25%. In other words, the most realistic picture is not Brent falling quickly into the low $90s, but rather a range-bound environment where further sharp spikes are capped.

2.2 Containment of US CPI/PPI Pass-Through into Core Inflation

The second trigger is US inflation. More important than whether energy prices are high in isolation is whether they pass through into core inflation.

The April headline CPI was +3.8%, with a significant energy contribution. But core CPI also came in at +2.8%, or +0.4% month-over-month. If that monthly pace persists, the annualized rate approaches 5%. In that scenario, even if oil stabilizes, inflationary pressure already transmitted into services, transportation, and shelter will linger.

In the next CPI and PPI releases, what matters more than the headline is core. If core CPI steps down to +0.2%–+0.3% month-over-month and PPI transportation and services decelerate, markets can breathe. Conversely, if core CPI prints +0.4% again and PPI services rise further, Fed rate-cut expectations recede even further.

The key dates: June 11 (US May CPI), June 12 (US May PPI), and June 27 (US May PCE). One deceleration is a signal; two consecutive prints confirm a trend.

2.3 BOJ June Meeting Guidance

The third trigger is the BOJ. Markets already have a substantial probability of a 25bp hike — from 0.75% to 1.00% — at the June meeting priced in. The hike itself is therefore not the critical variable. The critical variable is the tone following the hike.

If the BOJ hikes but characterizes the path as “gradual” and “data-dependent,” markets can take comfort. Even if Governor Ueda leaves the door open to further tightening, a low-implied pace of subsequent hikes would allow both JGBs and US Treasuries to stabilize.

Conversely, if the BOJ strongly validates the path to consecutive hikes, the shock will not remain contained within Japan. JGB yields would push higher, the incentive for Japanese investors to add new positions in US Treasuries would weaken further, and the term premium embedded in the US 10-year would face additional upward pressure.

BOJ message	Market interpretation	Yield impact
Gradual, data-dependent	One hike then a pause	Stabilizing
Justifies further hikes	Consecutive hike path validated	Worsening
Emphasizes yen stability	Reduces import-price pressure expectations	Stabilizing
Emphasizes upside inflation risks	Triggers additional JGB long-end selling	Worsening

A single sentence from the BOJ June meeting can move the US 10-year yield by roughly 10bp. We are in a phase where Japan’s policy dynamics are directly linked to the US Treasury market.

2.4 Recovery in US 10-Year and 30-Year Auction Demand

The fourth trigger is US Treasury auction results. The supply-demand dimension of the long-yield shock is most transparently revealed in auction data.

The May 30-year auction was weak. Bid-to-cover was soft and the tail widened — meaning the clearing yield was higher than the market had anticipated. One weak auction can be treated as an isolated event, but a pattern of weakness reads as a structural demand shortfall.

If the next 10-year and 30-year auctions show a recovering bid-to-cover, a tighter tail, and indirect bidder participation returning above 65%, long-term yields can find a footing. If weak auctions recur, the 30-year sustaining above 5.2% becomes a real possibility.

Key dates to watch: June 10-year and 30-year auctions, and the quarterly Treasury Refunding Announcement on July 30. If the Treasury signals an increase in long-end issuance, the supply burden on long-dated yields grows heavier.

2.5 Risk-Asset Correction Triggering Flight to Safety

The fifth trigger is a paradoxical stabilization path. If long-term yields rise too rapidly, risk assets eventually break. Mortgage rates climb, corporate credit spreads widen, equity multiples compress, and consumption slows. At that point, markets begin repricing growth deceleration and the possibility of eventual Fed easing.

In this case, long-term yields can come down. But it is not a good stabilization. It is a bad equilibrium in which bonds rally only because equities and real estate have sold off.

The stabilization signals here are: an S&P 500 correction of 5–10%, VIX above 25, high-yield spreads widening by at least 50bp, softening consumption and employment data, and an increasing number of Fed officials citing growth concerns. I put the probability of this pathway at 20–30%. It is not, however, a scenario any investor should welcome.

3. One-to-Three-Month Scenarios

The most probable scenario at present is not a fast stabilization but a range-bound consolidation.

Scenario	Probability	Conditions	US 10-Year	Japan 10-Year
A. Fast stabilization	20–25%	Hormuz normalizes, Brent below $95, CPI/PPI decelerate	4.2–4.4%	2.3–2.5%
B. Range-bound consolidation	45–50%	Oil stays elevated but further spikes are capped, BOJ hikes gradually	4.4–4.7%	2.5–2.8%
C. Renewed seizure	25–30%	Brent at $110–$120+, inventory draws persist, BOJ and Fed both turn more hawkish	4.8–5.0%+	Approaching 3.0%

Scenario A requires Hormuz normalization and US disinflation to materialize simultaneously — possible but not high-probability. Scenario C requires oil prices, auction results, and the BOJ to all deteriorate together. The most likely outcome is the middle path: oil remains elevated without spiking further, the US 10-year oscillates between 4.4% and 4.7%, and the Japan 10-year moves in the 2.5%–2.8% range.

Asset-Class Implications

Asset	Fast stabilization	Range-bound	Renewed seizure
US equities	Bullish	Volatility expands	Correction
US mega-cap tech	Bullish	Sideways	Significant correction
Korean KOSPI	Recovery	Sector divergence	Foreign selling
Korean growth stocks	Recovery	Weakness	Significant correction
Korean financials	Sideways	Relative strength	Relative strength
US long-duration bonds	Bullish	Bearish	Significantly bearish
US dollar	Weakness	Sideways to strength	Strength
Gold	Partial profit-taking	Bullish	Bullish
Oil refining/LNG	Weakness	Bullish	Significantly bullish
Defense	Weakness	Bullish	Significantly bullish

4. The Traps in Betting on Stabilization

The first trap is fixating on Fed communication alone. In a conventional market environment, when the Fed turns more dovish, yields fall. But this is not a market driven solely by Fed policy expectations. Inflation premiums, term premiums, bond supply dynamics, and the BOJ are all moving simultaneously. Even if Fed communication improves, the other factors can undercut any rally.

The second trap is treating a Hormuz agreement announcement as the definitive end of the episode. If an agreement is announced, Brent crude and long-term yields could react sharply on the day. But restoring actual vessel traffic, rebuilding inventories, normalizing refined product prices, and eventually seeing core CPI decelerate — all of that takes time. The announcement-day reaction is the first response; the 30-to-60-day verification period determines the true direction.

The third trap is reading this yield surge as nothing more than a short-term convulsion. The short-term geopolitical trigger is real. But simultaneously present are structural factors: US fiscal deficits, term premium normalization, BOJ normalization, and the weakening of Japanese marginal demand for US Treasuries. A return of the 10-year below 4% the way it used to trade is therefore a low-probability scenario. The more realistic target is stabilization in a 4.0%–4.5% range.

5. Practical Monitoring Checklist

The first thing to watch is Brent crude. Brent stable below $95 for at least one week is a stabilization signal. A re-break above $110 is a deterioration signal. Second, watch US core CPI and PPI: month-over-month needs to step down to +0.2%–+0.3%. Third, watch the precise language in the BOJ June statement. “Gradual” and “data-dependent” language is reassuring; any phrasing that validates consecutive hikes is a red flag.

Next, watch the US Treasury auctions. The question is whether demand recovers in the 10-year and 30-year. Finally, watch risk assets themselves. A sharp equity selloff can paradoxically drive a flight to long-duration bonds — but that is not a good scenario.

Priority	Indicator	Stabilization threshold	Deterioration threshold
1	Brent crude	Stable below $95 for 1+ week	Re-breaks $110
2	IEA/EIA weekly inventories	Draw rate decelerates	Draws sustained above 5 mb/day
3	US core CPI/PPI	MoM +0.2–0.3%	+0.4% repeated
4	Fed hike probability	December hike probability below 20%	Above 50%
5	BOJ June guidance	Gradual, data-dependent	Consecutive hikes justified
6	Japan import prices/PPI	Deceleration	Additional surge
7	US 10-year/30-year auctions	Bid-to-cover recovers, tail narrows	Weak auctions repeated
8	USD/JPY	Stable below 155	Re-breaks 160
9	US 30-year yield	Recovers below 5.0%	Settles above 5.2%
10	Japan 30-year yield	Below 3.8%	Settles above 4.0%

Entry Conditions for a Stabilization Bet

Staged entry can be considered when at least three of the following five conditions are met:

Brent crude holds below $95 for at least one week.
The next CPI/PPI release confirms core inflation deceleration.
The BOJ June meeting delivers gradual, data-dependent tightening guidance.
Demand recovers at US 10-year and 30-year Treasury auctions.
The US 10-year fails to sustain above 4.6% and begins to turn lower.

Three or more: first tranche entry is reasonable. Two or fewer: stay in cash. Zero to one: a defensive posture or positioning for further weakness is more rational than betting on stabilization.

6. Implications for the Korean Market

In a fast-stabilization scenario, semiconductors and AI hardware, KOSDAQ growth names, and platform companies are likely to react first. When discount rates fall, long-duration assets are the fastest to rebound.

In the range-bound scenario, the picture is different. Rates do not fall sharply, but they do not worsen either. In this environment, semiconductor components, substrates, test equipment, shipbuilding/LNG, defense, and value/financial stocks hold up better on a relative basis. Sectors with earnings momentum can weather the macro overhang even if it does not fully clear.

In a renewed-seizure scenario, oil refining/LNG, defense, short-duration bonds, and cash equivalents are the defensive plays. KOSDAQ growth stocks and long-duration assets are best avoided.

Scenario	Favorable areas in Korea	Areas to avoid
Fast stabilization	Semiconductors, AI hardware, KOSDAQ growth, platforms	Oil/defense — some profit-taking
Range-bound	Semiconductor components/substrates/test, shipbuilding, defense, financials	Growth stocks without earnings
Renewed seizure	Oil refining, LNG, defense, cash equivalents	KOSDAQ long-duration assets

7. Frequently Asked Questions

Won’t everything resolve once the Fed eventually cuts?

It is not that simple. Even if the Fed cuts short-term rates, long-term yields are shaped by term premiums, bond supply dynamics, foreign buyer behavior, and fiscal deficits. In 2024, there were extended periods when the US 10-year refused to fall materially despite active Fed rate-cut expectations. Monitoring only Fed communication is insufficient this cycle as well.

If Japan dumps Treasuries, doesn’t that cause a collapse?

What matters more than outright selling is the deterioration of marginal demand. Japanese insurers and pension funds do not need to actively sell US Treasuries. Simply reducing new purchases weakens the marginal demand balance in the Treasury market. That is the quieter but more structurally significant risk.

Isn’t this a buying opportunity in long-duration bonds?

With yields elevated, the expected return on long-duration bonds has improved. But entry timing still matters. If the US 10-year climbs further from 4.6% to 4.8%, long-bond prices will experience additional drawdowns. Full allocation is therefore inferior to trigger-based staged entry: consider a first tranche when three of the five triggers are met, a second tranche at four, and complete the allocation if all five confirm.

8. One Final Thought

US 10-year at 4.46%, 30-year at 5.02%, Japan 10-year at the highest level since 1997. This is not a simple Fed hawkishness event. It is the result of expected short-term rates, inflation premiums, term premiums, and bond supply premiums all moving higher simultaneously. Improvement in a single factor will not produce stabilization.

The single most powerful variable is Hormuz and oil prices. They are the common shock that simultaneously determines US inflation and Japan’s import prices. The negotiation outcome in late May to early June is the first potential inflection point.

At this juncture, scenario probabilities stand as follows: fast stabilization 20–25%, range-bound consolidation 45–50%, renewed seizure 25–30%. The most probable outcome is the middle path. Rather than betting on a return of the 10-year below 4%, the more realistic target is stabilization in a 4.0%–4.5% range.

It is too early to bet heavily on stabilization. Staged entry after at least three of the five triggers — Hormuz, CPI/PPI, BOJ guidance, US Treasury auctions, risk-asset correction — are confirmed is the more defensible approach. The most dangerous assumption is that time alone will resolve this cycle. This episode contains not only a short-term geopolitical convulsion but also structural elements: fiscal dominance and term premium normalization.

This may not be a market returning to low rates, but rather one in which — at a higher discount rate — the gap between strong assets and weak assets widens. In that environment, the true alpha does not come from simply betting that rates fall. It comes from identifying assets with the earnings and cash flows to hold their ground even when rates stubbornly refuse to decline.

Japan's PPI Shock — The Real Fear Is Not Selling US Treasuries, but No Longer Buying Them. How BOJ Tightening Resets Global Rates

Fri, 15 May 2026 00:00:00 +0000

The market is talking about “Japan dumping Treasuries.” Japan’s PPI came in hot, BOJ rate-hike odds went up, the story goes that Japanese capital sells Treasuries and goes home. That story is only half right. The real risk is not “Japan dumping Treasuries” but “Japan no longer buying them.” When the world’s largest foreign Treasury holder stops adding, prices fall even without selling. And when the US 10-year yield rises, the global discount rate rises with it — which reprices every risk asset, in the US and in Korea.

Key takeaways

The mechanism in one line: Japan PPI shock → BOJ hike probability ↑ → JGB yield ↑ + JPY-strength expectations ↑ → post-hedge Treasury return ↓ → Japanese marginal bid for Treasuries ↓ → UST term premium ↑ → global discount rate ↑.
The core idea: this is not a “selling event,” it is marginal-demand erosion. Japan does not need to dump anything. Simply not adding is enough to push prices lower (yields higher).
Why it matters: Japan is the world’s largest foreign holder of US Treasuries, with ~USD 1.13 trillion. When that marginal bid weakens, the supply-demand balance breaks.
Second-order effects: US 10-year up → global discount rate repriced → US big-tech multiples compressed → Korean equity risk premium affected.
Checkpoints: BOJ policy meetings, the JGB 10-year, USD/JPY, GPIF / Japanese life-insurer asset-allocation language, NY Fed 10-year term-premium estimates.

1. What people get wrong — this is not “selling,” it is “no new buying”

1.1 The wrong story going around

The wrong narrative:
"Japan inflation surprised → BOJ hikes →
 Japanese money sells Treasuries and goes home →
 US yields spike → stocks crash."

Why it's inaccurate:
1. Japanese lifers and pension funds hold USTs as quasi-collateral,
 not as a tactical risk position — they can't easily sell.
2. Outright large-scale selling would shock both FX and rates markets,
 so any move would be gradual.
3. The realistic transmission is not "dumping" — it is "buying less."

1.2 The actual mechanism

The correct chain:

Japan PPI shock
 ↓
BOJ tightening probability ↑
 ↓
JGB yields ↑ + JPY-strength expectations ↑
 ↓
Post-hedge UST yield falls (from the Japanese investor's POV)
 ↓
Japanese lifers / pension funds reduce NEW UST allocations
 ↓
Marginal UST demand weakens
 ↓
UST term premium ↑ (= long-end yields ↑)
 ↓
Global discount rate repriced
 ↓
Valuation pressure across risk assets

The point: not “selling,” but “weaker new buying.” Even if Japan never sells a single Treasury, simply slowing additions pushes UST prices down (yields up).

2. Four concepts for the first-time reader

2.1 Currency hedging

What is FX hedging?

When a Japanese life insurer buys a US Treasury:
1. Convert yen to dollars
2. Buy the Treasury in dollars
3. At maturity, convert dollars back to yen

Problem: if USD/JPY moves in the interim, the JPY-equivalent value
can fall.

Solution: "currency hedge" — lock in the future FX rate upfront.

Analogy: buying foreign currency before a trip.
→ Eliminates FX risk
→ But costs a fee (the hedge cost)

The hedge cost is essentially the rate differential:
US rate − Japan rate ≈ hedge cost

Example: US 5%, Japan 0.5%
→ Hedge cost ≈ 4.5%
→ 10-yr UST yield 4.5% − hedge cost 4.5% = 0%
→ The Japanese investor's "post-hedge return" is effectively zero.

2.2 What happens to Japanese investors when BOJ hikes

When BOJ raises rates:

1. JGB yields rise
 → Decent yield is available at home
 → Less reason to reach overseas

2. Hedge cost narrows
 → US rate − Japan rate = hedge cost
 → As Japanese rates rise, the hedge cost falls
 → BUT a higher JGB yield is itself more attractive

3. JPY appreciation expectations
 → If the yen is expected to strengthen,
 the unhedged USD asset will translate back into fewer yen
 → "JPY-strength risk" gets priced on top of hedge cost

Net result:
The post-hedge return on USTs can turn negative for Japanese buyers.
→ JGB looks much better
→ Japanese investors slow NEW UST purchases.

2.3 Term premium

What is term premium?

Long-bond yields decompose into two parts:
1. The average of expected future short rates (the policy-rate path)
2. The "term premium" — compensation for the risk of locking up money
 for years

In plain English:
"Who knows what 10 years from now looks like? The premium is what you
get paid for that uncertainty."

When does term premium rise?
- Inflation uncertainty ↑
- Fiscal-deficit concerns ↑
- Supply/demand worsens (fewer buyers)
- Volatility ↑

If term premium rises 100bp:
→ 10-year yield rises \~100bp
→ Short rates can be unchanged while the long end climbs
→ "Curve steepening."

2.4 Japan = world’s largest foreign holder of US Treasuries

Japan's US Treasury holdings:

End-2024: \~USD 1.13 trillion
#1 globally (#2 China \~USD 0.79T, #3 UK \~USD 0.75T)

Composition:
- Japanese life insurers
- Japanese pension funds (GPIF, etc.)
- Japanese megabanks
- Japanese asset managers

Characteristics:
- Long-duration holders
- High FX-hedge ratio (\~50–70%)
- "Marginal buyer" — allocates fresh inflows to USTs every year

→ When that marginal bid weakens, the UST supply-demand balance breaks.

3. The mechanism with numbers

3.1 Post-hedge UST yield for a Japanese investor

Post-hedge 10-year UST yield (Japanese investor view):

UST 10-yr yield − hedge cost = effective return

Hedge cost ≈ short-rate differential (US − Japan)

Today (illustrative):
US short rate: 4.50%
Japan short rate: 0.50%
US 10-yr yield: 4.30%

Hedge cost = 4.50% − 0.50% = 4.00%
Post-hedge UST yield = 4.30% − 4.00% = 0.30%

Compare:
JGB 10-yr yield: 1.50%
→ For a Japanese investor: JGB 1.50% > hedged UST 0.30%
→ Domestic bonds beat US bonds.

3.2 What changes if BOJ hikes 50bp

BOJ policy rate 0.50% → 1.00% (+50bp)
JGB 10-yr 1.50% → 2.00% (assumed)
US rates unchanged (assumed)

Hedge cost = 4.50% − 1.00% = 3.50% (50bp lower)
Post-hedge UST yield = 4.30% − 3.50% = 0.80%

Compare:
JGB 2.00% vs hedged UST 0.80%
→ Gap widens to 1.20pp
→ The relative appeal of USTs for Japanese investors gets worse

Layering in JPY-strength expectations:
→ The unhedged portion of the UST exposure faces JPY translation losses
→ Net incentive to buy more USTs falls further.

3.3 How weaker marginal demand pushes UST yields up

UST market supply-demand:

Annual net issuance: \~USD 1.5–2.0 trillion
Main buyers:
- Federal Reserve (currently in QT — actually shrinking holdings)
- Domestic US (banks, money-market funds)
- Foreign (Japan, China, UK, euro area)
- Hedge funds, asset managers

Japan's typical annual net UST buying: \~USD 50–100 billion

If that drops by half:
→ \~USD 25–50 billion of marginal bid disappears
→ Who replaces it?
→ Domestic US investors or other foreign holders must absorb it
→ For them to do so, yields must rise
→ Term premium widens.

Estimated impact:
Weaker Japanese marginal demand alone could lift the US 10-year
by \~20–40bp.
(Midpoint of academic estimates — the exact number is hard to verify.)

4. Why this matters for global asset prices

4.1 The US 10-year = global discount-rate anchor

Every asset is, ultimately, the present value of future cash flows.

Price = future cash flows / (1 + discount rate)^t

The discount-rate anchor is the US 10-year Treasury yield.

If US 10-yr rises from 4% → 5%:
- US equity PERs compress (especially long-duration growth)
- EM equity risk premia get repriced
- Real-estate valuations face pressure
- Corporate-credit spreads widen

Big-tech is most affected:
→ Big-tech is heavily weighted toward distant future cash flows.
→ A higher discount rate haircuts those distant flows more.
→ AI-linked high-multiple names are the most sensitive.

4.2 How it lands on Korean equities

Direct channels:
1. Foreign-investor flows — higher US rates compress EM weights
2. Korean 10-yr yields move with the US — Korean PER compresses
3. USD/KRW upward pressure (when USD strengthens)

Indirect channels:
1. Some Japanese capital sits in Korean bonds too
 → If it repatriates, Korean bond demand softens
2. Korean growth names (Naver, Kakao, biotech) are sensitive to
 the US discount rate
3. Semiconductors are AI-cycle driven, so relatively defensive,
 but the multiple still gets squeezed

Relative winners / losers:
Friendly: financials, value, short-duration cash-flow names
Hostile: growth, biotech, high-PER thematic names

5. Is this the same story as “yen carry-trade unwind”?

Partly. Both are mechanisms where Japanese monetary / rate policy changes shift global capital flows, but the emphasis differs.

Yen carry-trade unwind:
→ "Sell global assets bought with cheap borrowed yen and repay the yen"
→ Emphasis: selling (unwind)
→ Hit in August 2024 (a brief global equity drawdown)

This Japan PPI shock:
→ "Japanese lifers / pension funds slow NEW UST buying"
→ Emphasis: weaker marginal demand (no new buys, not selling)
→ More gradual but more structural

What they share:
→ BOJ tightening is the trigger in both
→ Both come with JPY strengthening

How they differ:
→ Carry unwind is a short shock (days to weeks)
→ Marginal-demand erosion accumulates over quarters and years
→ Carry unwind hits volatile assets
→ Marginal-demand erosion hits UST yields and the global discount rate

6. What to watch from here

6.1 Japan-side indicators

Indicator	Why it matters
BOJ policy decision	The next meeting is pivotal. Is the path priced in?
Japan PPI / CPI	Transient or structural inflation
JGB 10-year yield	Higher JGB = lower post-hedge UST appeal
USD/JPY	JPY strength raises the hedge-burden for Japanese investors
GPIF / lifer asset-allocation language	The actual behavioral signal

6.2 US-side indicators

Indicator	Why it matters
US 10-year yield	Most direct readout
NY Fed term-premium estimates	ACM / KW models — close to 100bp is dangerous
MOVE (UST option volatility)	Treasury-market stress gauge
TIC foreign-holdings data	Hard data on Japanese buying / selling (2-month lag)

6.3 Scenarios

Scenario	US 10-year	Korean equities
A. Gradual BOJ hikes + US demand absorbs the slack	4.0–4.5% range	Limited impact
B. BOJ accelerates + term premium climbs	4.5–5.0%	Pressure on growth / high-PER
C. Actual Japanese selling materializes	5.0%+	Broad risk-asset correction

Base case sits between A and B. C is low probability, high impact.

7. How this links to other posts

Samsung Electronics piece: "The memory supercycle is the real story"
→ AI semis are structurally demanded, so relatively resilient to
 short-term rate shocks
→ But the multiple (PER) can still get squeezed.

US-China summit piece: "May 15 foreign-flow data is the next check"
→ Foreign flows respond to US rates, USD, and USD/JPY together
→ Japan PPI shock is yet another foreign-flow variable.

Consumer-rotation piece: "Capital is rotating out of semi-concentration"
→ Higher US rates accelerate the unwind of growth crowding
→ Relative tailwind for value and financials.

8. The one-line bottom line

Japan’s PPI shock is not the “fear of Japan dumping US Treasuries.” It is “the fear that the world’s largest foreign holder might stop adding” — marginal-demand erosion.

This is not a selling event; it is a structural shift in supply-demand. More gradual, but more durable. Even without selling, when the marginal buyer disappears, prices fall (yields rise). The term premium widens, that lifts the US 10-year, that resets the global discount rate, that flows through to every risk asset.

The precise structural equation:

Japan PPI shock
→ BOJ hike probability ↑
→ JGB yield ↑ / JPY expectation ↑
→ hedged UST return ↓
→ Japanese marginal bid for UST ↓
→ UST term premium ↑
→ global discount rate ↑

What we actually need to watch is not “will Japan sell Treasuries?” but “where will Japanese lifers and pension funds allocate fresh money?” The BOJ meeting, the JGB yield, and GPIF / lifer language — together those three are the new control panel for the global risk-asset discount rate.

This article is research and commentary only and is not investment advice. Japan’s US Treasury holdings of ~USD 1.13 trillion are per US Treasury TIC data and vary by reporting period. The hedge-cost calculation is a simplified model; in practice currency basis, CDS spreads, and other factors apply. Term-premium estimates reference the NY Fed’s ACM (Adrian-Crump-Moench) and KW (Kim-Wright) models. The assumption that a 50bp BOJ policy-rate hike maps to a 50bp move in the 10-year JGB is illustrative — the actual bond-market reaction can differ. The +20–40bp estimate for the US 10-year impact from Japanese marginal-demand erosion is a midpoint of academic ranges and is hard to verify precisely. The comparison with the yen-carry unwind is a mechanism contrast — the two phenomena can also occur simultaneously. The analysis may be wrong. Data cut-off: May 15, 2026 KST.

Why Everything Is Moving Together — Reading Iran, Oil, US CPI, China, and Japan as a Single Cycle

Fri, 15 May 2026 00:00:00 +0000

What actually happened between May 14 and 15? US April PPI printed +6.0% YoY, the largest since 2022. Japan’s PPI hit +4.9%; the JGB 10-year reached its highest since 1997. The US 10-year is at 4.46%; the 30-year at 5.02%. Brent is 108 USD. The Strait of Hormuz has been effectively closed for two months. The Xi–Trump summit ended in a “small deal.” The market is reading these as separate news items. That is the wrong frame. These five variables are not independent events — they are one cycle. Iran is the origin; a higher global discount rate is the terminus. Draw the picture once, and the next headline will tell you where it will land in other asset classes.

Key takeaways

What the market is actually pricing: the variables that shook May 14–15 markets — Iran/Hormuz, oil, US inflation, the US-China summit, Japan PPI — are one cycle, not five independent events.
Origin: Iran/Hormuz bottleneck → global crude supply shock.
Terminus: higher US long rates → repriced global discount rate → multiple compression across risk assets.
Five transmission links: ① Iran/Hormuz → ② oil → ③ US CPI/PPI → ④ Fed-cut-pricing fades + US long rates rise → ⑤ Japan PPI → BOJ tightening → weaker Japanese marginal bid for USTs → further long-end yield rise (self-reinforcing).
The role of the US-China summit: not a cause of the cycle but a side variable that speeds it up or slows it down.
For Korean equities: the semi / auto concentration unwinds; refining, LNG, and defense get relative tailwinds; growth and long-duration names face pressure.
The single most important variable: when Hormuz normalizes. It decides where the cycle ends.

US-China summit = side variable that accelerates or delays the cycle.

Once you see this picture, the next headline will tell you which asset class it will land in.

2. Variable 1 — Iran / Hormuz: the cycle’s origin

2.1 Why Hormuz is the origin

Why the Strait of Hormuz matters:

Geography: a narrow strait between Iran and Oman (\~33 km at narrowest)
Function: the ONLY maritime exit for Persian Gulf crude and LNG to
 reach the rest of the world

Numbers:
- \~25–35% of global seaborne crude passes through
- \~20 million barrels per day
- Saudi Arabia, UAE, Kuwait, Iraq, Iran all depend on this strait

When Hormuz closes:
→ \~10.5 mb/d of Gulf-6 crude shut in
→ US SPR releases offer partial offset
→ Global inventories draw fast (\~250 mn bbl in Mar–Apr)
→ Brent stays above USD 100

Why this is not "just geopolitics":
→ Oil itself is the anchor of global inflation
→ Direct pass-through to CPI / PPI everywhere
→ Direct input into central-bank policy
→ Knock-on effects across rates and risk

2.2 Where we are on May 15

Hormuz has been functionally closed since February 28
Brent ~108 USD
IEA: 2026 global supply -3.9 mb/d, demand -0.42 mb/d, net deficit 1.78 mb/d
EIA: 2Q global inventory draw of ~8.5 mb/d on average
Iran foreign minister: “we don’t trust the US — won’t negotiate if they’re not serious”

2.3 Key judgment

Even when Hormuz normalizes, prices normalize later.

Reasons:
1. Bringing 10.5 mb/d of shut-in capacity back takes time
2. Infrastructure damage, mine-clearing, insurance / shipping restart
3. IEA: "refining margins likely stay historically elevated even
 after restart"
4. Inventory rebuild demand (the \~250 mn bbl draw needs replacing)

EIA STEO: full recovery of the shut-in 10.5 mb/d = "late 2026 / early 2027"

→ The market is pricing "Hormuz deal = oil down"
→ Reality: even with a deal, price normalization runs 6–9 months late.

3. Variable 2 — how oil transmits to US inflation

3.1 First-order: headline CPI / PPI

US April:

Indicator	MoM	YoY
Headline CPI	+0.6%	+3.8% (highest since May 2023)
Core CPI	+0.4%	+2.8%
PPI	+1.4%	+6.0% (largest since Mar 2022)
Gasoline (PPI)	+15.6%	—
Energy (CPI)	+3.8%	+17.9%

A 0.6% monthly print annualizes to ~7.4%; PPI’s +1.4% annualizes to ~18%. Single-month annualization overstates the run rate, but what the bond market reacts to is direction.

3.2 Second-order: services and shelter

Oil doesn’t just push headline.

Oil up → transport costs up → every good gets repriced
Oil up → airfares, travel up → services inflation
Oil up → heating, electricity up → shelter cost
Oil up → fertilizer up → food prices

What we saw in the April print:
- Airfares up
- Shelter +0.6%
- Food-price pressure
- Transportation services up

→ Not "just energy spiked"
→ A signal of broad-based inflation
→ The kind of mix the Fed can't ignore.

3.3 Third-order: Fed policy expectations reset

Three months ago: market expected 2–3 cuts of 25bp in 2026.

May 15 today:
- Cut expectations all but priced out
- December "hike" probability 36% (was 16% a week ago)

→ The policy cycle is being reset in the opposite direction
→ As the "cuts in the price" come out
→ The whole curve, short to long, gets reset.

4. Variable 3 — higher US long rates: the cycle terminus

4.1 The short end and the long end are different

Short rates (2-year):
- Move almost mechanically with the Fed policy rate
- Don't move much if the Fed stays on hold

Long rates (10-year, 30-year):
- Average of expected future short rates + term premium
- Term premium = "compensation for locking your money up for 10 years"

What lifts term premium:
1. Inflation uncertainty ↑
2. Fiscal-deficit concerns ↑
3. Supply / demand deterioration (fewer buyers)
4. Volatility ↑

→ Right now 1, 3, and 4 are all firing.

4.2 Where we are on May 15

US 10-year: 4.46%
US 30-year: 5.02%

This is NOT just "the Fed sounded hawkish."

Decomposition:
- Inflation concerns (CPI / PPI re-acceleration)
- Fiscal deficit (\~USD 2T per year)
- Issuance pressure (USD 9T of maturities + USD 2T net new)
- Weaker marginal bid from foreign buyers (Japan, China) ← key
- A weak 30-year auction this month

→ All of it compresses into one word: "term premium up."

5. Variable 4 — Japan PPI: the second axis that reinforces the cycle

5.1 The global price shock hits Japan too

Japan is a net importer of energy and raw materials:
- Crude: 99% imported
- LNG: mostly imported
- Fertilizers, grains: heavily imported

Hormuz bottleneck → Japan import-price surge
- Japan April import prices +17.5% YoY (in JPY)
- Japan April PPI +4.9% (highest in three years)
- JGB 10-year 2.55% (highest since 1997)

→ The BOJ can no longer hold the accommodative line
→ Market prices a 77% probability of a June BOJ hike.

5.2 How BOJ tightening transmits into US Treasuries

The chain:

BOJ hike probability ↑
 ↓
JGB 10-year yield ↑ + JPY-strength expectations ↑
 ↓
Post-hedge UST return ↓ (for Japanese investors)
 ↓
NEW UST buying falls (selling not required — marginal bid weakens)
 ↓
UST supply-demand balance breaks
 ↓
US 10-year yield rises further

* This is the "no new buy" scenario, not a "dumping" scenario
* More gradual, but more structural.

The detailed mechanism is in a separate post — the key point is that Japan is the UST market’s marginal buyer. Even without selling, when the marginal bid weakens, prices fall (yields rise).

5.3 The self-reinforcing loop

Oil up (Iran / Hormuz)
 ↓
US CPI / PPI up ←──────┐
 ↓ │
US long rates up │
 ↓ │
Japan import prices up │ (feedback)
 ↓ │
Japan PPI up │
 ↓ │
BOJ tightening expected │
 ↓ │
Japanese UST demand ↓ │
 ↓ │
US long rates up further─┘

→ Once started, the loop reinforces itself.
→ Hard to break without Hormuz normalizing.

6. Variable 5 — US-China summit: a side variable

6.1 Recap of the summit

From an earlier post:

Outcome	Detail
Agreed	Hormuz reopening understanding, H200 export licenses to China (10 firms), discussion of USD 30B tariff relief on non-sensitive items
Not agreed	Joint statement, rare-earth waiver extension, semiconductor-equipment control easing, Taiwan arms-sale changes
Xi quote	“Taiwan is the most important issue in US-China relations”
CSIS view	“A largely China-friendly, surface-level truce”

6.2 How the summit affects the cycle

Scenario A (Hormuz normalization accelerates):
→ Xi joins diplomatic pressure on Iran
→ Partial Hormuz reopening
→ Oil settles below 95 USD
→ The cycle "slows"
→ US inflation pressure eases
→ Cap on long-rate upside

Scenario B (small deal ends here, Hormuz unresolved):
→ Summit impact limited
→ Cycle keeps running
→ Oil stays in the 100s
→ US long-rate pressure persists
→ Global discount rate rises further

As of May 15:
We are closer to scenario B.
→ Hormuz remains functionally closed
→ Iran says "we don't trust the US"
→ No clear trigger to stop the cycle.

6.3 Why the summit is a “side variable,” not the engine

The summit didn’t create the cycle. The cycle was already running, with Iran/Hormuz as its origin. The summit is a variable that accelerates or slows the cycle.

Accelerators:
- US proceeds with Taiwan arms sales
- China tightens rare-earth controls
- Summit collapse or unilateral outcomes

Decelerators:
- China joins diplomatic pressure on Iran
- A Hormuz reopening deal
- USD 30B tariff easing actually implemented

→ The market focuses on the summit itself,
 but the right question is "what does the summit do to Hormuz?"

7. Korean equities — how the cycle works through here

7.1 Direct transmission

US long rates up
 ↓
Global risk-asset discount rate up
 ↓
KOSPI / KOSDAQ PER compression

Specifically:
- Foreign flows trim EM weights
- Korean 10-year yields rise in sympathy
- USD/KRW pressure up (with USD strength)
- Korean long-duration assets (growth, biotech) under pressure.

7.2 Relative strength by sector

Sector	Cycle effect	Read
Refining	Crack spreads at all-time highs; direct oil-up beneficiary	Relative strength
LNG / shipbuilding	Hormuz reroute demand, energy security	Relative strength
Defense	Iran + Taiwan risk overlap	Relative strength (already run a lot)
Semiconductors	AI demand is the body; multiple still squeezed	Neutral
Banks	Higher rates expand NIM	Relative strength
Consumer staples	Earnings-driven names (Samyang Foods etc.)	Selective strength
Autos	Already +29% in May	Neutral to weak
Petrochemicals	Naphtha cost up, margin pressure	Relative weakness
Airlines	Oil + rates double-whammy	Relative weakness
High-PER growth	Most sensitive to discount-rate moves	Relative weakness
Biotech	Long-duration squeeze	Weakness

7.3 The “least-priced” pocket of the cycle

As the earlier US-China summit piece argued — the market digested the summit as a “semiconductor news,” while the second-order effect of a Hormuz deal (lower naphtha → recovering petrochemical margins) is still unpriced.

As of today:
→ Semiconductors +39% (MTD): priced
→ Autos +29%: priced
→ Rare-earth theme: catalyst spent
→ Refining / LNG / defense: partly priced
→ Petrochemicals: latent recovery if Hormuz normalizes (NOT priced)
→ Banks: BOK hike potential (NOT priced)

Most asymmetric setups:
- If Hormuz normalizes quickly: petrochemicals, airlines
- If Hormuz drags on: refining, LNG, defense
- If the cycle stops: banks (on a BOK hike).

8. Scenarios and checkpoints

8.1 Three scenarios

Scenario	Premise	US 10-year	Korean equities
A. Cycle ends	Hormuz normalizes, oil sub-90, BOJ delays	4.0–4.3%	Relief in risk. Growth rebounds
B. Cycle persists (base)	Hormuz drags, oil 100–110, BOJ hikes in June	4.4–4.7%	Volatility widens; sector dispersion
C. Cycle accelerates	Hormuz worsens, oil 120+, actual Japanese selling	5.0%+	Broad risk-off, foreign outflows

Base case is B. A requires a Hormuz normalization. C requires confirmed Japanese UST selling.

8.2 Checkpoints (priority order)

1. Hormuz traffic normalization ★★★★★
 - Single most important variable
 - Decides where the cycle ends
 - Watch: daily tanker counts, Iran statements, OPEC+ comments

2. Does the US 10-year settle around 4.6%? ★★★★
 - The visible gauge of term-premium expansion
 - Watch: daily bond markets, auction results

3. Brent in the 95–110 range? ★★★★
 - Decides the strength of first-order transmission
 - Watch: daily oil prices, EIA / IEA weekly inventories

4. BOJ June meeting outcome ★★★
 - The Japan-axis decision point
 - Watch: June BOJ statement, JGB 10-year reaction

5. Japanese UST holdings data (TIC) ★★★
 - Actual confirmation of the marginal-demand erosion
 - Watch: US Treasury monthly data (2-month lag)

6. US May / June CPI / PPI ★★★
 - Whether the cycle keeps running
 - Watch: June 11 May-CPI, June 12 PPI

7. US-China follow-up negotiations ★★
 - Direction of the side variable
 - Watch: trade-committee product lists, rare-earth waiver decision.

9. How this connects to the whole series — every post sits on this cycle

The cycle in this post is the common background for the recent series:

Samsung Electronics piece (Citi target KRW 460,000):
→ "AI is structural demand," so relatively resilient to the cycle
→ But the multiple (rates) still squeezes.

Samsung Electronics piece (strike vs memory supercycle):
→ Price gains partly offset strike losses
→ The price spike itself is a CHILD of this cycle (supply tight + prices up).

Samsung Electro-Mechanics piece (MLCC, FC-BGA):
→ AI thesis intact
→ But at KRW 1.02M, multiple pressure bites directly.

Jeju Semiconductor piece (commodity memory):
→ Memory shortage from AI + the cycle pulls oil up too
→ Double tailwind, but multiple still squeezed.

Pearl Abyss piece:
→ Strong fundamentals, but a KOSDAQ long-duration asset
→ Cycle acceleration = multiple compression risk.

Samyang Foods + consumer-rotation piece:
→ Semi crowding unwinds → capital rotates
→ Stronger cycle = relative tailwind for value / earnings names.

Robotics (Robotis / Rainbow):
→ High-multiple growth
→ Cycle acceleration = the worst duration squeeze.

US-China summit piece:
→ Side-variable analysis
→ The logic of finding the "least-priced" pocket.

Japan PPI piece:
→ Detailed mechanism for the Japan axis of the cycle.

→ Every post is a piece or an application of this cycle.

10. The one-line bottom line

The events of May 14–15 — US April PPI +6.0%, Japan PPI +4.9%, JGB 10-year at a 28-year high, US 10-year 4.46%, 30-year 5.02%, Brent 108, a small-deal US-China summit — are one cycle, not five independent events.

The origin is Iran / Hormuz. The first transmission is oil, the second is US and Japanese inflation, the third is central-bank policy shifts, the fourth is higher US long rates, and the terminus is a repricing of the global discount rate → multiple compression in risk assets. The US-China summit didn’t create the cycle; it can only accelerate or delay it.

Once you draw the picture, every future headline tells you which asset class it will land in. The single most important checkpoint is when Hormuz normalizes. That’s where the cycle ends. If Hormuz normalizes within June, the cycle ends and a risk-on relief move is possible. If it drags, US long rates have more room, and a discount-rate repricing intensifies.

Chasing risk now without checking the cycle is inefficient. First locate the cycle — where it is, where it’s going — then evaluate asymmetric bets at the stock level. Great companies get derated when the cycle accelerates; mediocre companies can rebound when the cycle stops. The cycle comes before the stock.

This article is research and commentary only and is not investment advice. US April CPI / PPI are per the BLS official release. Japan April PPI / import prices are per the BOJ Monthly Report. US 10-year and 30-year yields, JGB 10-year, and Brent prices reflect May 14–15 market data. The Hormuz shut-in and inventory draws are per the IEA Oil Market Report (May 2026) and the EIA STEO (May 2026). The US-China summit outcomes are per Chinese MFA, the White House, Reuters, and Yonhap reporting. Scenarios, checkpoints, and sector views are the author’s judgments and not confirmed outcomes. The cycle description is a general mechanism — actual asset prices respond to many other factors. The timing of Hormuz normalization, the BOJ hike, and any actual Japanese UST selling are all uncertain. The analysis may be wrong. Data cut-off: May 15, 2026 KST.
