A Federal Reserve official recently pushed back on the idea of central banks meddling in each other's monetary policy decisions. The stance underscores a broader principle: when it comes to interest rates, inflation targets, and currency management, each nation's central bank should focus on its own house first. This matters for crypto markets too—when major central banks coordinate heavily or overstep into others' affairs, it can create policy confusion and trigger unexpected capital flows. Clean boundaries between monetary authorities typically mean more predictable markets.
