The U.S. Treasury's recent strategy to double its long-end bond buybacks to at least $4 billion per operation, aiming to reduce long-term borrowing costs, has largely failed to calm the bond market. After an initial brief dip following the announcement, Treasury yields quickly rebounded, with the 10-year Treasury note reaching 4.71% and the 30-year yield climbing to 5.26% by Friday, surpassing their levels prior to the buyback announcement. This indicates that underlying concerns regarding persistent inflation, expanding government debt, and significant borrowing by AI-focused tech firms continue to drive up yields. The move was a response to long-bond yields hitting their highest levels since 2007, but investors are seeking more lasting support.
Treasury Secretary Scott Bessent had indicated the buyback program, which began in 2024, could further increase beyond $4 billion, suggesting a larger toolkit is available. However, market participants like JPMorgan analyst James Sullivan likened the intervention to "paying your mortgage with your credit card," suggesting it may only postpone a deeper problem. The market's reaction, including a rise in the breakeven rate (a measure of inflation expectations) across the curve, indicates that the buyback, despite its intent, has inadvertently fueled inflation worries.
The persistent rise in yields is attributed to several factors. Inflation fears, exacerbated by geopolitical events such as the war in Iran, remain prominent. Additionally, U.S. Treasuries face increased competition from higher-yielding government debt in Asia and Europe, a record-setting surge in issuance from hyperscalers investing in artificial intelligence, and a general increase in term premiums. These factors contribute to the extra yield investors demand for holding U.S. debt, which recently surpassed the $40 trillion mark. The elevated yields mean that borrowing costs for mortgages, corporate loans, and consumer credit remain high, dampening economic activity.
