Bessent Slams Warren for Not Understanding FX; Warren Fires Back: Trump's Economy Is Crushing Families

The dispute between Treasury Secretary Scott Bessent and Senator Elizabeth Warren over the Trump administration's intervention in the yen has escalated into a heated clash.

Scott Bessent Blasts Elizabeth Warren Over Yen Intervention

On Friday, Bessent escalated the dispute after Warren pressed him for details on the U.S. intervention to prop up the yen.

"In her latest half-baked letter to me, @SenWarren made clear she knows even less about foreign exchange markets than she does about banking," Bessent wrote on X, referring to Warren's August 13 letter.

Bessent also suggested that Warren and her staff take an introductory international finance course, offering to provide a "FX 101" tutorial.

In her latest half-baked letter to me, @SenWarren made clear she knows even less about foreign exchange markets than she does about banking.

Equally shocking but unsurprising: not a single person in the media mob possesses even the most basic level of financial literacy...

At the center of the dispute is the Treasury's use of its Exchange Stabilization Fund to sell euros and buy yen, after the yen plunged to a 40-year low. Warren had argued that U.S. taxpayers could ultimately bear the cost if Japan failed to repay the Treasury.

Bessent Says Japan Owes the Treasury Nothing

Bessent dismissed that claim, stating the Treasury merely converted its existing foreign-currency holdings into yen.

"No new congressional appropriation is involved, and no credit has been extended to Japan. Japan owes the Treasury nothing," Bessent wrote in a reply on Thursday.

He argued the intervention was necessary because turmoil in Japan's currency market could spill over into global markets and potentially push up U.S. borrowing costs.

However, the Treasury has not disclosed the amount of yen purchased, the execution rate, or the current value of the position. Photos of Bessent's notes taken by Reuters showed a yen target of "$5 billion to $10 billion," but the Treasury has not confirmed that figure.

Elizabeth Warren Fires Back at Bessent

"It's been a tough few weeks for Secretary Bessent," Warren wrote on X while sharing Bessent's post. "His efforts to prop up foreign currencies haven't worked."

She also pointed to external criticism of Bessent's Treasury market policies and argued the administration should focus on the economic pressures facing American families.

It's been a tough few weeks for Secretary Bessent.

His efforts to prop up foreign currencies haven't worked. His failed intervention in the Treasury market was slammed by his own mentor as burning "two centuries" of credibility.

Trump's economy is crushing families. Maybe he should focus on that.

The U.S. intervention marks a rare move in foreign exchange markets, as the Treasury's last direct intervention to support the yen was in 1998.
