Treasury Yields Post Largest Weekly Drop Since February on AI Debt Concerns

U.S. Treasury yields fell sharply for the week, with the benchmark 10-year note posting its largest weekly percentage drop since mid-February. The move was driven by a significant rotation into safe-haven government bonds as investors grew wary of the substantial debt being issued by technology companies to fund artificial intelligence buildouts.

Flight to Quality Amid Tech Debt Fears

A growing skepticism around the financing costs and return timelines for massive AI capital expenditures triggered a broad de-risking across markets. According to the report, concerns were exacerbated by news of cloud provider CoreWeave’s $50 billion debt pile, which highlighted the scale of borrowing in the sector.

This flood of corporate debt issuance reportedly crowded credit markets, leading to wider corporate credit default swaps (CDS). In response, institutional investors began rotating out of high-grade corporate bonds and into more liquid, risk-free U.S. Treasuries, a classic flight-to-quality move that also pressured equity indices.

Fed Chair Signals Data-Dependent Approach

Bond markets also found support from comments by Federal Reserve Chairman Kevin Warsh. Speaking at the IMF and World Bank annual meetings, Warsh declined to signal future interest rate moves, reinforcing the central bank's data-dependent stance ahead of its late-October policy meeting.

"Policymakers will carefully assess developments across economic output, employment, and inflation ahead of our remaining meetings this year," Warsh stated, according to the report. This neutral tone solidified market expectations that the Fed will likely keep rates on hold at its October 27–28 meeting, further easing upward pressure on yields.
