European central bankers left the Jackson Hole symposium last week expressing concern over recent U.S. policy actions that they view as potential threats to transatlantic financial stability.
The latest tensions stem from a U.S. Treasury intervention on August 1, when authorities moved to support the Japanese yen by selling euros to purchase yen, according to Treasury Secretary Scott Bessent. European officials said they were not given advance notice of the operation, a customary practice in major currency interventions. Bessent also outlined plans to expand buybacks of longer-dated U.S. Treasuries, a strategy that could be financed through increased issuance of shorter-term debt.
European policymakers interpreted these measures as evidence of Washington’s willingness to intervene more aggressively to suppress borrowing costs. One source questioned whether pressure might eventually be applied to the Federal Reserve to purchase bonds directly. The Treasury rejected this interpretation, stating that the goal of the buyback expansion is to enhance market liquidity rather than impose a ceiling on interest rates.
A Treasury official said on Thursday that the department aimed to push long-term yields lower after they moved beyond what officials considered fair value. The official added that the changes were part of a broader effort to stabilize debt markets rather than a signal of broader policy shifts.
Discussions at Jackson Hole also touched on the Fed’s dollar swap lines with major central banks, which provide dollar liquidity during periods of financial stress. Some European officials expressed unease that political tensions could undermine these facilities, though no immediate threat was identified. The Treasury emphasized that swap line decisions remain solely with the Federal Reserve, and officials expect the arrangements to remain intact.
Fed Chair Kevin Warsh has sought to rebuild international relationships since taking office, including a recent trip to Europe that officials described as broadly constructive. The Jackson Hole gathering highlighted the growing divide between U.S. and European approaches to monetary and fiscal policy, even as central bankers acknowledged the need for continued cooperation.
