European central bankers fear erosion of U.S. policy norms

The frustration centers on the U.S. Treasury’s recent sale of euros to support the Japanese yen, a move executed without the customary heads-up to European counterparts. One official described the lack of communication as infuriating, arguing that the episode signals a shift toward a policy of unilateral action regardless of international protocol. While some delegates suggested the oversight might have been accidental, the prevailing sentiment is that the current administration increasingly prioritizes domestic political goals over traditional diplomatic coordination.

Beyond currency maneuvers, the Treasury’s strategy to increase buybacks of longer-dated bonds has sparked fears of broader market volatility. European bankers worry that these interventions, aimed at capping borrowing costs, could set a dangerous precedent or invite political pressure on the Federal Reserve to adopt similar measures. The concern is that such actions, if they escalate, could trigger market upheavals that transcend American borders.

Even the stability of dollar liquidity swap lines—a bedrock of the global financial system—is now being viewed through a lens of skepticism. Although these facilities remain under the independent control of the Federal Reserve, some international officials worry that the administration’s aggressive trade stance could eventually bleed into monetary cooperation. Despite these tensions, Fed Chair Kevin Warsh has attempted to maintain a steady hand, working to preserve institutional relationships even as the broader political environment remains fraught with uncertainty.
