# Credit spreads hit a 17-month high as the AI trade loses its nerve Published 2026-10-23 ยท Business Services on MarketScale Canonical: https://www.marketscale.com/industries/business-services/credit-spreads-hit-a-17-month-high-as-the-ai-trade-loses-its-nerve > Global corporate bond premiums widened to 129 basis points, the most since May 2025, as an AI stock selloff and geopolitical tension sent investors into Treasuries. Asian high-grade spreads followed. The cost of borrowing just rose for every company, not only the ones building data centers. ## Key points - Global corporate bond spreads hit 129 basis points on October 23, the widest level since May 2025. - Credit spread widening raises borrowing costs across sectors, including hospitals, industrial companies, and other non-tech borrowers. - Debt-funded AI spending by technology and data center companies has created investor concern about whether future profits will service the borrowed capital. The bond market has started charging for the AI boom. Global corporate bond yield premiums widened to as much as 129 basis points on October 23, the widest since May 2025, according to a Bloomberg index cited by Bloomberg reporters Katherine Doherty, Finbarr Flynn and Dipika Lalwani. The move followed a selloff in AI stocks and a rise in geopolitical tension that pushed investors toward the safest assets they could find. ## Understanding credit spreads A credit spread is the extra yield a company pays over a government bond. When it widens, every new borrowing gets more expensive and every existing bond loses value. Seventeen months is a long time in credit; the last time premiums sat at this level, the market was still absorbing the spring 2025 tariff shock. > Bloomberg characterized the day as the biggest risk-off move in more than a year. The trigger, per Bloomberg, is doubt about the pace of debt-funded AI spending. Technology companies and the data center developers behind them have borrowed heavily to build capacity, and investors are increasingly asking whether the profits will arrive in time to service that debt. ## Equity side perspective Finimize described the same mechanism from the equity side. If data center and chip spending needs more cash than planned, the largest technology companies lean harder on debt and stock issuance, and the market responds by discounting their distant earnings more steeply. That hits long-duration growth stocks first and sends money toward shorter-duration sectors and sovereign bonds. Finimize also pointed to the geopolitical leg: oil rose 4% in the prior session on Houthi attacks on Saudi Arabia, and Asian shares slid on Friday as investors moved into government bonds and safe-haven currencies. The flight to safety was visible on the other side of the ledger. U.S. Treasuries rallied for their best day in more than two years, with gains across the curve, as traders unwound bearish positions and covered short bets, Bloomberg reported. Finimize put the rally at the largest in more than three years. The two outlets measure it differently, but both describe the strongest one-day bid for Treasuries in years. ## Impact on Asia and investor sentiment Asia felt it at the open on Friday. Spreads on dollar bonds from higher-rated Asian companies widened to their highest since July 2025. Regional credit default swaps moved about 1.5 basis points wider to 78. Chinese technology spreads widened 3 to 5 basis points, Chinese investment-grade names were indicated as much as 5 basis points wider, and Indian and Korean investment-grade spreads widened up to 3 basis points, according to traders cited by Bloomberg. > Both can be right for a while: demand for compute can keep rising even as the market reprices the risk of paying for it with borrowed money. The debate among the largest investors is not settled. Bloomberg reported that Citadel's Ken Griffin has warned of an AI bubble, while Blackstone president Jon Gray said he sees no cause for concern and described demand as close to parabolic. ## Consequences for borrowers and future trends For finance leaders outside technology, the practical effect is immediate and indiscriminate. A widening in the global index raises the cost of new issuance for an industrial borrower or a hospital system as surely as for a chipmaker. Companies with refinancing scheduled for the next two quarters should expect to pay more than their last deal, and treasurers who have been waiting for better conditions may have already seen them. - The first is whether the AI-linked issuers that drove the spread widening can still place debt at acceptable prices, which will show in the primary market over the next few weeks. - The second is whether equity volatility settles, since the credit move tracked the stock selloff rather than any single default. - The third is the Treasury rally itself: a 17-month high in spreads alongside a multi-year high in government bond demand describes a market that has decided to be paid for risk again, and that preference tends to persist once it starts. ## Limitations in reported figures One caution on the figures. Bloomberg's story gives the headline level and the Asian detail but does not name the index, and some secondary outlets have attached numbers to specific companies' credit default swaps that the original reporting does not contain. The 129 basis point figure and the May 2025 comparison are the facts to rely on. ## Sources - [AI Tech Fears Push Global Credit Spreads to 17-Month High](https://ca.finance.yahoo.com/news/ai-tech-fears-push-global-021332089.html) (Bloomberg) - [AI Tech Fears Push Global Credit Spreads to 17-Month High](https://www.bloomberg.com/news/articles/2026-10-23/ai-tech-fears-push-global-credit-spreads-to-17-month-high) (Bloomberg) - [AI Funding Jitters Rattle Markets And Lift Treasuries](https://finimize.com/content/ai-funding-jitters-rattle-markets-and-lift-treasuries) (Finimize) Tags: credit markets, corporate bonds, AI investment, capital markets, risk-off, corporate finance --- Source: MarketScale, https://www.marketscale.com/industries/business-services/credit-spreads-hit-a-17-month-high-as-the-ai-trade-loses-its-nerve.
