Bessent escalates market intervention as Treasury buybacks become a tool to lean against rising yields
U.S. Treasury Secretary Scott Bessent has moved aggressively this year to contain borrowing costs, pairing currency intervention with Japan, signaling potential cuts to long-dated debt issuance, and then announcing that buybacks of 10- to 30-year Treasuries would be at least doubled. Bloomberg described him as the most activist Treasury secretary in financial markets in decades. Markets reacted quickly: on the day of the latest buyback move, the 10-year Treasury yield fell about 6 basis points, the 30-year yield dropped nearly 9 basis points, and the dollar index slid to a three-month low. The strategy has drawn attention because of Bessent’s background. He worked at Soros Fund Management during the 1992 sterling trade and later helped lead other macro bets, including a $1 billion yen short in 2013. Critics now argue that the same instinct for spotting pressure points is being applied to defend, rather than attack, a stressed market. Economists and market participants quoted by Bloomberg question whether intervention can do more than alter near-term pricing. Federal net interest expense reached $963 billion in the first 10 months of fiscal 2026, while the deficit hit $1.8 trillion. Several observers said buybacks and FX operations do not address the deeper drivers of long-end yields: deficits, spending, refinancing at higher rates, inflation expectations, and Federal Reserve policy.
