Large, ongoing fiscal deficits are now the primary driver of the U.S. economy, a factor many macro analysts are missing. This sustained government spending creates a higher floor for economic activity and asset prices, rendering traditional monetary policy indicators less effective and making the economy behave more like a fiscally dominant state.
Recent inflation was primarily driven by fiscal spending, not the bank-lending credit booms of the 1970s. The Fed’s main tool—raising interest rates—is designed to curb bank lending. This creates a mismatch where the Fed is slowing the private sector to counteract a problem created by the public sector.
When national debt grows too large, an economy enters "fiscal dominance." The central bank loses its ability to manage the economy, as raising rates causes hyperinflation to cover debt payments while lowering them creates massive asset bubbles, leaving no good options.
A country's fiscal health is becoming a primary driver of its currency's value, at times overriding central bank actions. Currencies like the British Pound face a "fiscal risk premium" due to borrowing concerns, while the Swedish Krona benefits from a positive budget outlook. This creates a clear divergence between fiscal "haves" and "have-nots."
A condition called "fiscal dominance," where massive government debt exists, prevents the central bank from raising interest rates to cool speculation. This forces a flood of cheap money into the market, which seeks high returns in narrative-driven assets like AI because safer options can't keep pace with inflation.
Due to massive government debt, the Fed's tools work paradoxically. Raising rates increases the deficit via higher interest payments, which is stimulative. Cutting rates is also inherently stimulative. The Fed is no longer controlling inflation but merely choosing the path through which it occurs.
'Fiscal dominance' occurs when government spending, not central bank policy, dictates the economy. In this state, the Federal Reserve's actions, like interest rate cuts, become largely ineffective for long-term stability. They can create short-term sentiment shifts but cannot overcome the overwhelming force of massive government deficit spending.
When government spending is massive ("fiscal dominance"), the Federal Reserve's ability to manage the economy via interest rates is neutralized. The government's deficit spending is so large that it dictates economic conditions, rendering rate cuts ineffective at solving structural problems.
When countries run large, structural government deficits, their policy options become limited. Historically, this state of 'fiscal dominance' leads to the implementation of capital controls and other financial frictions to prevent capital flight and manage the currency, increasing risks for investors.
The U.S. government's debt is so large that the Federal Reserve is trapped. Raising interest rates would trigger a government default, while cutting them would further inflate the 'everything bubble.' Either path leads to a systemic crisis, a situation economists call 'fiscal dominance.'
In periods of 'fiscal dominance,' where government debt and deficits are high, a central bank's independence inevitably erodes. Its primary function shifts from controlling inflation to ensuring the government can finance its spending, often through financial repression like yield curve control.
