Janet Yellen on Fiscal Dominance

Janet Yellen, in remarks given on January 4, 2026, expressed concern that the preconditions for a fiscal dominance regime are strengthening in the U.S. economy. She defined this regime as a situation where large government deficits and debt pressure monetary policy, forcing the central bank to keep interest rates lower than warranted or absorb government debt primarily to ease the government's financing burden, rather than achieving its dual mandate of price stability and maximum employment. She explicitly contrasted this with the current structure, which she characterized as a monetary dominance regime, noting that the Federal Reserve raised rates sharply post-pandemic despite worsening fiscal arithmetic.

The dangers she outlined for a shift to fiscal dominance include higher and more volatile inflation, politically driven business cycles, and unanchored inflation expectations, making price stabilization much more costly later. The basis for her concern rests on the Congressional Budget Office’s projection of a steep upward trajectory for debt, with net interest costs rising significantly as a share of GDP, alongside persistent large deficits. Avoiding this outcome, she stressed, requires a credible, medium-term fiscal adjustment from Congress and the president, as political pressure from high debt service costs could compromise institutional protections for the Fed's independence, though she concluded the U.S. is not in that regime today.
