Treasury Secretary Scott Bessent dared currency and bond market traders to challenge his interventions on Tuesday, hours before the Treasury Department was set to reveal how large it would make its bond buyback program.

"I am the house now," Bessent said at a Southern Methodist University event in Texas on Tuesday, referring to his department's moves to support the Japanese yen, according to Bloomberg. "And you can bet against me if you want."

The Treasury is expected to announce around 11 a.m. Wednesday the size of its bond buyback operation, according to CNBC. The actual buyback operation will not take place until Thursday.

Bessent framed his yen intervention as giving him an informational edge over traders. "When we intervene with the Japanese yen, I have pretty good insight into what the Bank of Japan is going to do, what Japanese policymakers are going to do," he told Bloomberg. "I have asymmetric information."

On the bond side, the Treasury announced last month it would at least double the maximum size of its buyback operations for longer-dated securities, setting a floor of $4 billion per operation for 10-to-20-year and 20-to-30-year bonds — double the prior level. Speculation has grown since then that the figure announced Wednesday will be larger still. "Something in the $5 billion to $6 billion range now seems likely to be the starting point for the discussion, and we cannot rule out something larger," analysts at Wrightson ICAP said in a note, according to CNBC.

The yen intervention was designed in part to prevent Japan from selling its U.S. Treasury holdings. With Japan sitting on $1.1 trillion of U.S. debt — the single largest foreign position — any move by Tokyo to offload Treasurys would drive yields upward, a serious concern given that total U.S. debt has now crossed $40 trillion and the annual deficit is closing in on $2 trillion. According to Bloomberg, the yen operation was carried out in close coordination between Bessent and Japan Finance Minister Satsuki Katayama.

Since the buyback announcement, the 10-year yield has climbed roughly 10 basis points, with the 30-year yield also moving higher. BMO Capital Markets' Ian Lyngen, who leads rates strategy at the firm, has characterized 5.3% on the 30-year as a threshold Bessent effectively drew in the sand.

Not everyone is persuaded that Bessent's approach will hold. Stanley Druckenmiller, the billionaire investor who mentored Bessent early in his career, called the buyback expansion a "mistake" driven by "price management." "Governments defending prices against fundamentals always lose," Druckenmiller wrote in a Wall Street Journal opinion piece. In a note cited by CNBC, Lyngen cautioned that the direction Bessent has charted risks undermining "the credibility of Treasuries as an asset class."
