The U.S. Treasury Department announced a surprise increase in its government debt repurchases, stating it would "at least double" the size of these operations, specifically targeting longer-term bonds from the 10-year to 30-year sector. This move, which will take effect on September 9, caused longer-term U.S. Treasury yields to drop sharply; the 30-year Treasury bond yield plunged from 5.26% to as low as 5.18%, while the 10-year yield fell from 4.68% to 4.63%. This unexpected decision by Secretary Scott Bessent aims to rein in soaring interest rates, which have pushed the 30-year Treasury yield to its highest level since 2007, increasing the federal government's borrowing costs. U.S. stocks initially rose, with the S&P 500 closing up 0.2% and the Nasdaq Composite up 0.16%.
Jim Bullard, former president of the Federal Reserve Bank of St. Louis, described the Treasury's action as an "important tactical move" and "a little bit unexpected" during an appearance on Bloomberg TV. However, he expressed skepticism about its long-term impact, stating, "I don't think it changes the fundamentals of big fiscal deficits and a Fed on the sidelines," which he believes are the true drivers of higher long-term yields. Other analysts, like Mohamed El-Erian, a professor at the Wharton School, suggested the move could temporarily lower mortgage rates but warned of potential "collateral damage and unintended consequences."
The increased buybacks involve targeting the 10- to 20-year and 20- to 30-year portions of the market, doubling the maximum size of operations from $2 billion to "at least" $4 billion. This action signals the Treasury's intent to be a more active participant in providing liquidity to the longer end of the bond market. While the announcement led to a temporary rally in long-dated Treasuries, some experts, including Evercore ISI's Krishna Guha, cautioned that it "changes almost nothing in terms of the fundamentals," pointing to the persistent need to finance large government deficits and a surge in corporate debt, particularly related to artificial intelligence. Joe Brusuelas, chief economist at RSM, also raised concerns that efforts to suppress yields could complicate the Federal Reserve's fight against inflation, given Chairman Kevin Warsh's preference for market-determined rates. The total increase in buybacks is estimated by Barclays strategists to be around $16 billion per quarter, or $64 billion annually, representing about 15% of the current annual supply of 20- and 30-year bonds.
The Treasury did not specify how the purchases would be funded, but analysts widely expect it to involve issuing more short-term bills, effectively rebalancing the maturity schedule rather than reducing overall debt. This approach echoes the Federal Reserve's "Operation Twist" playbook. The timing of Secretary Bessent's move, just ahead of the November Congressional elections, suggests a political motivation to curb borrowing costs and alleviate pressure on consumers, with Bessent having previously indicated that the level of 10-year yields served as a benchmark for the administration's success.
