Bessent, Warren clash over U.S. yen intervention

Treasury Secretary Scott Bessent and Sen.

Elizabeth Warren (D-Mass.) have turned a dispute over the Donald Trump administration’s intervention in the Japanese yen into a sharp clash.

Scott Bessent Slams Elizabeth Warren Over Yen Intervention On Friday, Bessent escalated the dispute after Warren pressed him for details about the U.S. intervention to support the yen. "In her latest sciolistic letter to me, @SenWarren made it clear that she knows even less about foreign exchange markets than she does about banking," Bessent wrote on X, referring to Warren’s Aug.

13 letter.

Bessent also suggested Warren and her staff take an introductory course in international finance, offering to provide a "Foreign Exchange for Dummies" tutorial.

What is equally shocking, but not surprising: not a single member of the media mob has a rudimentary-enough level of financial… pic.twitter.com/0mmp2tapqJ — Treasury Secretary Scott Bessent (@SecScottBessent) August 28, 2026 At issue is Treasury’s use of its Exchange Stabilization Fund to sell euros and purchase yen after the Japanese currency plunged to a 40-year low.

Warren had argued that U.S. taxpayers could ultimately bear the cost if Japan failed to repay Treasury.

"No new congressional appropriation was involved, and no credit was extended to Japan.

Japan owes Treasury nothing," Bessent wrote in a response on Thursday.

He argued the intervention was necessary because disorder in Japanese currency markets could spill into global markets and potentially increase U.S. borrowing costs.

However, Treasury has not disclosed the amount of yen purchased, the execution rate or the current value of the position.

A Reuters photograph of Bessent’s notes showed a target of "$5-10 bil." in Japanese yen, but Treasury has not confirmed that figure.

Elizabeth Warren Fires Back at Bessent "Tough couple weeks for Sec.

Bessent," Warren wrote on X sharing Bessent’s post. "His effort to prop up a foreign currency hasn’t worked." She also pointed to criticism of Bessent’s Treasury-market policies and argued that the administration should focus on economic pressures facing American households.

Tough couple weeks for Sec.

Bessent.

His effort to prop up a foreign currency hasn’t worked.

His failed intervention in Treasury markets was blasted by his mentor as burning "two centuries" of credibility.

Trump's economy is crushing families.

Maybe he should focus on that. — Elizabeth Warren (@SenWarren) August 28, 2026 The U.S. intervention marked a rare move in currency markets, with the Treasury last directly intervening to support the yen in 1998.
