U.S. Treasury Secretary Scott Bessent personally led a January “rate check” on the yen during its sharp slide against the dollar, according to senior U.S. officials cited by Nikkei, in a move designed to stabilise markets rather than respond to a formal Japanese request.
The check, conducted on Jan. 23 by the Federal Reserve Bank of New York at the Treasury’s direction, came as the yen weakened toward the 158 per dollar level amid political uncertainty ahead of Japan’s Feb. 8 lower house election. Officials said Bessent was concerned about broader market instability during what he described as a “political vacuum,” as well as the potential for spillovers into global bond markets.
Rate checks are typically viewed as a precursor to possible currency intervention, involving authorities sounding out financial institutions on pricing were official action to occur. Following the move, the yen strengthened sharply to around 155 per dollar.
According to U.S. officials, Japan’s Ministry of Finance had not requested either a rate check or coordinated intervention at the time. However, Washington would have considered joint action had Tokyo asked.
The backdrop included rising long-term Japanese government bond yields, with newly issued 40-year debt touching 4% for the first time. Selling pressure spilled into U.S. Treasuries, pushing 10-year yields toward 4.3%, before retreating toward 4.0% after the rate check.
Officials said Bessent believed markets were misreading signals from Japan’s bond market and feared that higher global yields could undermine broader financial stability. The action was described as consistent with a broader U.S. principle of using its economic strength to help stabilise allies.
Following the landslide election victory of Prime Minister Sanae Takaichi, U.S. authorities assess that political uncertainty has receded. They have also expressed confidence in Finance Minister Satsuki Katayama and Bank of Japan Governor Kazuo Ueda.
While no specific measures are currently planned, U.S. officials indicated close coordination with Japan will continue.
