AI Debt Starts Moving the U.S. Treasurys Market

The massive capital expenditure requirements for artificial intelligence infrastructure are driving significant shifts across global credit markets. Hyperscalers are utilizing a broad array of financing channels—including investment grade, high yield, and private credit across seven different currencies—to meet the demand for compute that currently outstrips supply. While initial financing focused on 20-plus year durations for entire data center builds, a strategic shift is emerging toward shorter five-year amortizing structures to fund rapidly obsolescing components like chips. This surge in corporate issuance is directly impacting the U.S. Treasury market; as dealers absorb corporate duration risk onto their balance sheets, they frequently sell Treasuries to manage risk, contributing to persistently high yields in the 20-plus year category. Political pushback and bipartisan opposition to data centers further complicate the landscape, introducing volatility and uncertainty regarding the future cadence of bond issuance.
