What is financial dominance?

Financial dominance is a condition in which the central bank's monetary policy decisions are constrained by concerns about financial system stability. When tightening policy to fight inflation would trigger a financial crisis, bank failures, or a severe market dislocation, the central bank may be forced to ease or pause even though inflation remains above target. In this scenario, financial stability considerations dominate the inflation mandate.

The March 2023 banking crisis provided a vivid example. The Federal Reserve was in the middle of an aggressive rate hiking campaign to combat 6%+ inflation when Silicon Valley Bank and Signature Bank failed. Despite inflation being well above target, the Fed created the Bank Term Funding Program, accepted collateral at par value, and eventually paused its hiking cycle sooner than it might have otherwise. While the Fed maintained that it could pursue financial stability and price stability simultaneously, the episode demonstrated how financial fragility can constrain monetary tightening.

Financial dominance is closely related to, but distinct from, fiscal dominance. Fiscal dominance occurs when government debt levels are so high that the central bank cannot raise rates without creating unsustainable debt service costs, effectively subordinating monetary policy to fiscal needs. Financial dominance is broader, encompassing not just government debt but the entire financial system: bank balance sheets, leveraged positions in markets, and the interconnected web of derivatives and repo funding. Both represent constraints on the central bank's freedom to set policy optimally for price stability alone.

For investors, the possibility of financial dominance has important implications. It suggests that there is an effective ceiling on how high or how quickly the Fed can raise rates, determined not by the inflation outlook but by the fragility of the financial system. Markets that are heavily leveraged and dependent on cheap funding create their own form of insurance against tight policy. This dynamic can be inflationary in the long run, as it limits the central bank's ability to fully tighten when needed. Recognizing when financial dominance is binding versus when the Fed has room to maneuver is essential for correctly positioning around tightening cycles.
