A gauge of global corporate spreads hit its widest since May 2025, U.S. junk-bond risk premiums reached a 17-month high and primary markets saw the year's biggest spate of pulled deals. The stress started with AI borrowers. It has not stayed there.
Stock investors spent the past week arguing about artificial intelligence. Bond investors quietly started charging more for corporate risk of every kind.
A Bloomberg index of global corporate bond spreads widened to 129 basis points, its widest since May 2025. Spreads on higher-rated Asian dollar bonds reached their widest since July of last year. In the U.S., the average risk premium on high-yield debt climbed to a 17-month high, and primary markets saw the year's biggest spate of pulled deals, Bloomberg News reported.
All of that happened in the same week that Treasuries had their best day in more than two years by one Bloomberg measure. On Thursday the 10-year yield fell 19.3 basis points. Investors were buying safety and selling risk at the same time.
Where the stress started
The strain has been sharpest around companies tied to the AI build-out. Analysts at Chase said that credit default swaps, which insure against a borrower's default, had reached record levels for several AI-linked companies. Protection on CoreWeave, a provider of AI computing capacity, traded above 1,000 basis points a year.
Nvidia has become a financier for parts of that build-out, including an arrangement promising financial firms up to $125 billion in residual value guarantees on financings of its graphics processors, according to CNBC. That role is now being tested as credit tightens for its partners. SK Hynix, meanwhile, halted plans to take its Solidigm storage unit public, citing market conditions and share-price trends, even though the U.S. factory the listing was meant to help fund is still needed.
Where it spread
The pulled deals are not all AI. Earlier in October, more than $5 billion of U.S. and European bond and loan sales from at least seven companies were postponed. They included a $690 million loan for AVI-SPL that was abandoned and a $485 million add-on for Radiology Partners that was pulled.
Investors who specialize in the riskiest debt are feeling it. Arini Capital Management, one of the larger hedge-fund investors in high-yield markets, told clients its main fund lost 6.9% in the first half of October after a 15.7% decline through September, according to an investor memo reported by Bloomberg. Arini's direct-lending fund, which held its final close on Oct. 21, is a separate strategy.
In exchange-traded funds the move was modest on Friday. The iShares iBoxx Investment Grade Corporate Bond ETF fell 0.4%, driven mostly by the rise in Treasury yields that day, while the iShares iBoxx High Yield Corporate Bond ETF was little changed.
Why buyouts are exposed
Leveraged buyouts and private equity exits are financed in the same markets that are now pulling deals. When buyers cannot raise debt on acceptable terms, they bid less, and sellers either accept lower prices or wait.
The link is visible in at least one live process. Veritas Capital's exploration of a sale of Chromalloy, which could value the aerospace business at more than $10 billion, was described by people familiar with the matter, according to Bloomberg, as likely to reach buyers in the coming weeks "barring a sudden change in market conditions." Wider spreads and pulled deals are the kind of change that phrase anticipates. Whether they affect that process is not known.
There is an escape route. In past periods when syndicated markets shut, sponsors turned to direct lenders, which can underwrite and hold loans without relying on a public sale. Arlington Capital Partners funded its take-private of Gooch & Housego with equity and then refinanced with a Blackstone-led unitranche loan. Radiology Partners shifted from a loan to a bond. Defaults, so far, are not alarming: Fitch put the U.S. leveraged-loan default rate at 3.9% in September.
Targeted or broad
One reading is that credit is repricing a specific group of borrowers. Record default-swap levels on AI-linked names, a pulled AI-memory IPO and pressure on AI cloud providers point to a focused reassessment of companies whose plans depend on borrowing, and private credit has the capital to step in where banks cannot syndicate.
The other is that this is a broad retreat from risk. Spreads widened globally, in Asia and in U.S. junk bonds, during a fortnight in which Brent climbed to $116, inflation worries resurfaced, unrest spread in France and consumer sentiment sat near record lows. On that view AI is simply the most visible casualty of tighter financial conditions, and the private equity industry's large backlog of unsold companies is about to get longer.
What to watch
Whether postponed deals return to market in November, corporate bond issuance from AI and data-center borrowers, whether U.S. spreads keep widening outside technology, and third-quarter results from Microsoft, Alphabet and Amazon this week and from listed private markets firms, including Blue Owl on Oct. 29 and Apollo on Nov. 3.
