Bundesbank warns US Fed's loss of independence could fuel global inflation

Joachim Nagel, president of Germany’s Bundesbank, warned that a weakening of the U.S. Federal Reserve’s independence would have consequences beyond U.S. borders by encouraging domestic political pressure on other central banks. Nagel argued the risk is primarily a precedent effect: if political actors succeed in shifting policy in a large economy, imitation and lowered political costs for intervention could spread. He stressed that the Eurosystem benefits from strong legal protections for independence, but that formal safeguards alone cannot fully insulate Europe from changed global norms and market reactions. Market channels — shifting expectations about future rates, higher term premia, wider risk premia and exchange-rate swings — would transmit any U.S. pivot to other economies, raising imported inflation and complicating price stability objectives. Nagel’s warning comes as public debate in the United States has included open criticism of rate policy and prominent voices in Washington signalling preferences, a dynamic that can blur the boundary between oversight and political pressure. That trend is reinforced by fiscal dynamics in the United States — large near-term borrowing needs and upcoming rollovers — which raise the political stakes of high rates and could tempt calls for easier policy. Messaging from Treasury and other officials, even when touting objectives like a strong dollar, can add to market uncertainty when other signals suggest a tilt toward lower rates. For central banks that recently restored low inflation, such external pressures would make it harder to anchor expectations and sustain credibility without costly policy reversals. Nagel urged policymakers to defend institutional safeguards and clear communication to prevent a slide toward short-term demand boosts that have longer-run inflationary costs. Investors and companies should therefore broaden scenario planning to include politically driven shifts in rate trajectories and greater volatility in bond and FX markets. Over time, the persistence of any change will depend on whether political incentives that favour easier policy outweigh the reputational costs of eroding central bank independence. Nagel’s intervention is a reminder that credibility is both an institutional and a political achievement, vulnerable to cross-border imitation if norms change in major economies.
