European Central Bankers Warn of Growing Friction with Washington Amid Treasury Interventions

During this year’s Jackson Hole Economic Symposium, European central bankers voiced growing unease about the future of U.S. cooperation, citing recent Treasury actions that they view as departures from long‑standing norms.

Federal Reserve officials took the opportunity to reassure their European counterparts that the Fed would uphold all of its commitments, but they were clear that the central bank cannot guarantee against sudden policy shifts from the U.S. administration, particularly under President Donald Trump.

The main point of contention was the Treasury’s intervention in the foreign‑exchange market. On August 1, the Treasury purchased Japanese yen, a move that was later described by Treasury Secretary Scott Bessent as a “reallocation of resources” sourced from the Treasury’s Exchange Stabilization Fund. European officials were frustrated that they were not given a customary heads‑up about the sale of euros that accompanied the yen purchase.

Some European policymakers viewed the transaction as an honest oversight, given its unusual nature, while others expressed frustration that the U.S. seemed to act unilaterally.

In addition to the yen intervention, Bessent announced plans to increase the Treasury’s buybacks of longer‑dated bonds, a strategy that may require the issuance of more short‑term maturities to finance the purchases. European central bankers warned that such measures could signal a willingness to take unconventional steps to cap borrowing costs, potentially prompting further market volatility.

The Fed remains the sole U.S. monetary‑policy authority, designed to operate independently of the elected administration. Nevertheless, the European officials noted that President Trump has demonstrated a willingness to pursue extraordinary measures to advance his agenda, heightening concerns about the stability of global financial cooperation.
