European Central Banks Explore Dollar Pooling to Reduce U.S. Reliance Amid Trump-Era Uncertainty

European financial stability officials are actively evaluating strategies to enhance resilience against potential disruptions to traditional dollar funding channels, with discussions focusing on creating an alternative to Federal Reserve backstops through pooled dollar reserves held by non-U.S. central banks . These deliberations follow policy shifts under U.S. President Donald Trump that have destabilized long-standing international financial relationships and raised questions about the independence of the Federal Reserve .

The Fed's swap lines—mechanisms that lend dollars to foreign central banks during market stress—have historically served as a critical tool for maintaining global financial stability . However, European officials now express concerns that these facilities could be weaponized by the Trump administration, given the U.S. president's aggressive tariff policies and rhetoric about reshaping international economic relationships . A key inflection point occurred in April 2025 when Trump's "Liberation Day" tariffs triggered systemic shocks, exposing vulnerabilities in banks' contingency funding plans .

While these concerns have somewhat abated following assurances from Federal Reserve Chair Jerome Powell at a July 2025 ECB-hosted conference, officials remain cautious about overreliance on U.S. institutions . The proposed dollar pooling mechanism would involve non-U.S. central banks collaborating to create an independent liquidity source, though officials acknowledge significant logistical and political hurdles to implementation .

The initiative reflects broader anxieties about the concentration of global financial power in U.S. institutions. European supervisors have repeatedly highlighted the dominant role of the Federal Reserve in crisis scenarios, particularly during episodes of dollar liquidity stress . This dynamic has become increasingly precarious under Trump's administration, which has pursued policies prioritizing U.S. economic nationalism over multilateral cooperation .

Market participants have observed subtle but measurable shifts in cross-border funding behavior since April 2025. Banks in the Eurozone and other regions have accelerated diversification of their dollar funding sources, including increased use of non-U.S. swap agreements and alternative reserve currencies . However, analysts caution that replacing the Fed's role in global liquidity management will require unprecedented coordination among central banks, given the scale and reach of U.S. financial infrastructure .

The potential reconfiguration of international liquidity networks carries implications for monetary policy effectiveness. If European central banks succeed in establishing a credible alternative to Fed facilities, it could alter the transmission mechanisms of U.S. monetary policy across global markets . Conversely, failure to implement such measures may leave European institutions more exposed to unilateral changes in U.S. financial policy .
