The ranking member of the U.S. Senate Committee on Banking, Housing and Urban Affairs, Elizabeth Warren, asked Treasury Secretary Scott Bessent to explain the administration’s use of the Exchange Stabilization Fund to purchase Japanese yen after the currency fell to a 40-year low. The letter seeks disclosure of the amount of taxpayer-linked funds deployed and the administration’s assessment of the intervention’s benefits and risks to the U.S. economy. Warren raised concerns about potential taxpayer losses, particularly if Japan were unable to repay the Treasury, and questioned whether the operation produced lasting results after the yen surrendered half of its post-intervention gains. She also sought information on the prospect of further intervention and the decision by the Treasury and Federal Reserve, acting as fiscal agent, not to notify the European Central Bank in advance that euros would be sold to fund the yen purchase.
