The Credit-Squeeze Case (S2): Demand Holds, Money Gets Dearer, and the Weakest Borrowers Pay First

Sat, 24 Oct 2026 16:20:00 +0900

On Oct 22 two things happened at once. The 10-year Treasury yield fell 17bp. US high-yield spreads rose 13bp in a day to 340bp, 10bp from the 350bp line we treat as bear confirmation.¹ Yields down and spreads up is the signature of S2, our credit-squeeze case.

We put S2 at 15% (subjective, Oct 24). This post reads the market as if S2 is the path. In S2, AI demand stays real and Big Tech keeps spending. What changes is the price of money. It does not get cut off; it gets dearer, starting with the weakest borrowers. The question for chip investors is how far up that chain the stress climbs before it reaches memory.

A companion post reads the same market through our base case, the rebound under a hawkish hold (S1).

Five things to take away

Under S2, demand holds but funding gets more expensive rung by rung. Hyperscaler-backed data-center bonds pay about 5.7–7.5%; CoreWeave’s unsecured 2032 notes yield about 15%.²
The stress is already climbing. High-yield spreads rose from 260bp on Aug 28 to 340bp. Oracle’s five-year CDS was reported near 315–322bp, from 144bp at the start of 2026. CoreWeave’s 2032 notes traded at 76–81 cents.¹³
S2 is only 15% because the broad market is still open. Investment-grade spreads are 89bp, below our 100bp bear line, and the BB index yields 6.85%, below 7.5%.¹
Memory feels S2 in 2028 orders, not in 2026–27 profits. Oracle and CoreWeave together are about $110–135 billion of 2027 spending, or 20–25% of the expected 2027 capex increase.⁴
In price, S2 means good earnings, a weak reaction and a failed bounce. KOSPI already sits 0.8% below its Jul 30 close and SK hynix 4.5% below.⁵

Prices are Oct 23 closes; Korean closes are final prints after the 20:00 KST extended session. Probabilities are our subjective estimates. Most credit prices below come from press reports, and we label them as secondary.

How today reads under S2

The money is not cut off, it gets dearer by rung

The AI build-out is not funded by one pool of money. It is a ladder.

At the top, data-center bonds backed by a hyperscaler lease or guarantee pay roughly 5.7–7.5%, close to Treasuries plus an investment-grade spread. One rung down, paper backed by CoreWeave leases pays about 10%. An unrated term loan backed by GPUs pays about 11.6%. At the bottom, CoreWeave’s unsecured 2032 notes yield about 15%.²

S2 says the ladder gets steeper from the bottom. Borrowers who rely on the bottom rungs, the neoclouds and the debt-funded part of the Oracle build, feel it first. A hyperscaler with AA credit barely notices. The first thing to shrink is the share of new capacity that neoclouds can fund, not total hyperscaler capex.

The stress is climbing

High-yield spreads. 260bp on Aug 28, 283bp on Jan 2, 340bp on Oct 22, including a 13bp jump that day.¹
Oracle. Five-year CDS reported near 315–322bp on Oct 19, up from 144bp at the start of 2026. We have not seen the original data, so treat it as secondary.³
CoreWeave. The 9.625% 2032 notes traded at 76–81 cents on Oct 16–19, a yield near 15%. Five-year CDS was about 1,090bp on Oct 19 after peaking at 1,194.5bp on Oct 15.³
Even the top names. Meta’s CDS closed at a record 114.79bp on Oct 22.⁶
Volume. Hyperscalers have issued about $255 billion of unsecured bonds this year, about 30% of 2026 capex, by Morgan Stanley’s count.⁷
Hidden leverage. S&P Global said it is “safe to assume there is more unreported debt.”⁸ Microsoft’s own 10-K shows leases signed but not yet started of $329.1 billion at Jun 30, up from $92.7 billion a year earlier, and it now calls some contracts conditional.⁹
The equity window. Firmus pulled its ASX listing on Oct 9. Nscale’s planned New York listing reportedly targets about $35 billion, while some investors offered $16–19 billion.¹⁰
Private credit. A $3.7 billion GPU-backed term loan to Volta was reported at about 95 cents and was not underwritten.¹¹

None of these alone is a crisis. Together they show the cost of capital rising at the weak end while AI demand news stays good.

Why S2 is still only 15%

The broad credit market has not joined in. That is the main reason S2 is not our base case.

Investment-grade spreads are 89bp, below our 100bp bear line and below the 2026 high of 94bp. The BB index yields 6.85%, below our 7.5% bear line.¹
Stronger borrowers still get money on decent terms. Nebius signed a $3.5 billion senior secured facility with Citi at SOFR plus 275bp, though it is a 364-day bridge.¹² CoreWeave’s DDTL 4.0 was rated investment grade at SOFR plus 225bp in March.¹³
The biggest buyer pays from cash. Microsoft generated about $67 billion of free cash flow in fiscal 2026.⁹
The weak link is small next to the whole. Barclays estimates that halving CoreWeave’s capex would equal about 2% of total AI capex.¹⁴

How far S2 would reach memory

Step 1: the weakest rung pays more. This is where we are now.

Step 2: marginal capacity shrinks. Oracle and CoreWeave together account for about $110–135 billion of 2027 spending. That is about 20–25% of the roughly $550 billion increase expected for 2027. This is a sensitivity, not a forecast. If that chain cut its spending in half, the hit would be about 10–12% of the increase. A CoreWeave half-cut alone is about 3.6%.⁴

Step 3: conditional leases break site by site. Contracts that depend on delivery dates and power can be cancelled one site at a time. The Microsoft–Nscale exit from Loughton in October is the template: Microsoft called it a single site, and reports pointed to grid delays.¹⁵

Step 4: memory feels it in 2028. Long-term agreements and contract prices lock in much of 2026–27. Under S2 the damage shows up in 2028 orders and in the multiple investors pay for memory profits, not in next quarter’s earnings.

That is why S2 can look strange. Results can beat while stocks fall, because the market is pricing the cost of capital and the life of memory profits, not unit demand.

What S2 looks like this week

Oct 28, SK hynix. Strong results with a weak reaction fit S2. So does a shareholder-return plan smaller than the KRW 30 trillion or more that brokers hope for.¹⁶
Oct 29 00:55 KST, Oracle investor day. The test is the funding mix. Goldman’s frame for fiscal 2027 is about $20 billion of equity (done), $20–25 billion of customer prepayments and about $20 billion of debt.¹⁷ An S2-consistent day: more debt or off-balance-sheet funding, a later date for positive free cash flow, and CDS still above 300bp.
Oct 29–30, Alphabet, Microsoft, Amazon. Capex up, free cash flow down and a weak price reaction. Listen for funding wording, not demand wording. Demand is not the S2 problem.
Oct 30–Nov 7, the bond window. Hyperscalers and partners usually issue after earnings. S2 shows up as wider new-issue concessions on big deals and high-yield spreads at 350bp or more.
The Nscale listing. A pulled or discounted deal supports S2.
Nov 11 07:00 KST, CoreWeave third quarter. Financing plan, capex and spreads on new secured debt. Our weekly bear lines are the 2032 notes below 70 cents or CDS at 1,500bp or more.

We use three credit gates for S2: high-yield spreads at 350bp or more, Oracle CDS at 300bp or more, and CoreWeave 2032 notes below 75 cents. We have not decided whether one gate or all three should move the probability, so we watch all three and say which ones are lit.

What S2 would look like in price

Our scenario table writes the S2 outcome as “good earnings, weak reaction; the rebound fails and the July lows are retested.” The retest is closer than it sounds. KOSPI closed Oct 23 at 5,550.30, 0.8% below its Jul 30 close. SK hynix is 4.5% below its July close. Samsung Electronics still has a 3.1% cushion.⁵

The July low lasted one day. On Jul 31 KOSPI rose 17.9% to 6,595.45, SK hynix closed at 1,718,000 won and Samsung Electronics at 262,500 won.⁵ Company buybacks did much of the buying under that rebound. Those programs have now ended: Samsung’s in early October and SK hynix’s on Oct 21.

So under S2 the question is not a crash from here. It is whether a bounce can start without that buyer and while money for AI gets dearer. We do not set a price target for S2.

What would push S2 back

High-yield spreads back at 330bp or less, and investment-grade at 85bp or less, after the bond window.
Oracle leans on customer prepayments instead of debt, and its CDS stays below 300bp for five trading days.
CoreWeave’s 2032 notes back above 80 cents.
A neocloud listing that prices normally.
The BB index yield below 6.5%.

Our read

Credit is the closest of our three bear-confirmation lines: high-yield spreads are 10bp from it. The other two, an annual cut to next year’s memory consensus and a Big Tech capex slowdown, have not fired. That is why S2 is 15% and not higher. Under S2, the most useful single tell is the post-earnings bond window. If big deals need wider concessions while results are strong, the market is repricing the cost of AI capital, and memory stocks will trade on 2028, not on 2027.

Your turn

Which rung do you think breaks first: the neocloud listings, Oracle’s funding mix, or CoreWeave’s bonds? And is an 89bp investment-grade spread telling the truth, or is it lagging? Tell me in the comments. I will check these lines again after CoreWeave reports on Nov 11.

If this helped you think about the credit side of the AI trade, a like helps other investors find it.
