The U.S. Treasury Department is preparing to announce the size of its upcoming buyback operation for long-dated U.S. debt, with details expected around 11 a.m. ET on Wednesday. While a prior announcement set the minimum buyback at $4 billion, analysts now anticipate the figure could be significantly higher, with Wrightson ICAP suggesting a range of $5 billion to $6 billion as likely, and not ruling out an even larger amount [1]. This operation, set to take place on Thursday, marks a notable shift in Treasury policy, as the $4 billion minimum is already double the typical size of such buybacks, and speculation is mounting that the actual figure will exceed this threshold [1].
Treasury Secretary Scott Bessent, speaking at Southern Methodist University, issued a pointed warning to currency traders, stating, "I'm the house now," in reference to the Treasury's efforts to support the Japanese yen. Bessent explained that the Treasury stepped in to buy yen so that the Bank of Japan would not need to sell its U.S. Treasurys. Japan, which holds $1.1 trillion in U.S. debt, could trigger a rise in yields if it began selling Treasurys, a risk amplified by the U.S. domestic debt surpassing $40 trillion and the deficit heading past $2 trillion [1].
Market reactions have already been observed, with the benchmark 10-year Treasury yield rising about 10 basis points (0.1 percentage point) since the buyback announcement, and the 30-year bond yield also edging higher, though it remains below the 5.3% level highlighted by BMO Capital Markets analyst Ian Lyngen [1]. Lyngen noted that this approach represents a departure from the Treasury's history of predictability and gradual change, expressing concern that it could negatively impact the credibility of Treasuries as an asset class [1].
Wrightson analysts described a $6 billion buyback as "fairly aggressive," and suggested that tripling or quadrupling the normal level would be "extreme" and would result in a much more visible deceleration in the net supply trajectory of U.S. debt [1]. The market is expected to closely monitor both the amount offered and the demand from debt holders during Thursday's operation [1].
CONCLUSION
The Treasury's anticipated aggressive buyback of long-dated U.S. debt signals a significant policy shift under Secretary Bessent, with potential implications for market confidence and Treasury yields. Analysts and markets are bracing for a larger-than-usual operation, and concerns have been raised about the long-term credibility of Treasuries as an asset class. The outcome of Thursday's buyback will be closely watched for its impact on yields and market sentiment.
