Treasury Secretary Scott Bessent took Sen. Elizabeth Warren to school on Friday, publicly mocking the Massachusetts Democrat for getting the basics of foreign exchange markets completely wrong in a letter she sent him about U.S. intervention in the Japanese yen. As if being a fake Indian wasn’t enough work for Elizabeth Warren, now she has this to worry about.
“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. He then generously offered Warren and her staff a tutorial he called “Foreign Exchange for Dummies” and accused the media of ignoring what he described as her “remedial error.” Elizabeth Warren, who sits atop the Senate banking committee, apparently needed a refresher on how currencies work. Who could have seen that coming.
The flap started with the Bessent Warren yen intervention dispute after Warren sent an Aug. 13 letter demanding details about Treasury’s decision to sell euros from its Exchange Stabilization Fund and buy yen after the Japanese currency hit a 40-year low. The problem? Warren’s opening paragraph suggested Japan owed money to Treasury, writing that “American taxpayers would ultimately bear the cost if Japan were unable to repay” the department. Bessent was happy to correct the record.
“Treasury exchanged existing Exchange Stabilization Fund foreign-currency assets for yen,” Bessent wrote in his Thursday response. “No new congressional appropriation was involved, and no credit was extended to Japan. Japan owes Treasury nothing.” To be fair to Warren, she did correctly describe the transaction later in the same letter. But hey, when you hand your opponent an opening like that, expect to get dunked on.
Bessent defended the yen intervention as necessary to protect American economic interests, arguing that a disorderly yen could destabilize global markets and drive up U.S. borrowing costs. The move marked the first coordinated U.S.-Japan effort to strengthen the yen since 1998. Japan itself spent the equivalent of about $96.5 billion supporting its currency between July 30 and Aug. 26, a record for that period according to Japanese Finance Ministry data released Friday.
Warren fired back on X with the kind of response you write when you know you walked into the door but refuse to admit it. “Tough couple weeks for Sec. Bessent,” she posted, arguing his intervention hasn’t worked, pointing to criticism of Treasury market moves, and piling on with “Trump’s economy is crushing families.” Senate banking committee Democratic spokeswoman Saloni Sharma also chimed in, saying Bessent should focus “on reducing the cost of living for the American families struggling in President Trump’s economy” rather than feuding with Warren.
Worth noting, Bessent’s response did leave several of Warren’s questions unanswered, including how much yen Treasury actually purchased, the execution rate, and the position’s current value, even though a Reuters photo from July 31 shows Bessent’s notepad reading “Buy Japanese Yen (JPY) $5-10 bil.” He also skipped her questions about whether the European Central Bank was consulted before the euro sale and the detailed legal justification she requested.
So the scorecard reads: Warren got caught with a factual error in the very first paragraph of her letter, Bessent corrected it publicly and hilariously, and Warren responded by changing the subject. The Treasury Department did not immediately respond to a request for comment, which tracks, because when you’ve already won the argument on X, why bother picking up the phone.
If being a fake Indian isn't enough, then try being a fake foreign exchange expert too!
