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.
After a decade of zero rates and QE post-2008, the financial system can no longer function without continuous stimulus. Attempts to tighten policy, as seen with the 2018 repo crisis, immediately cause breakdowns, forcing central banks to reverse course and indicating a permanent state of intervention.
The U.S. is approving stablecoins for a strategic reason: they require reserves, which must be U.S. treasuries. This policy creates a massive, new, non-traditional buyer for government debt, helping to finance enormous and growing fiscal deficits with a structural source of demand.
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 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 a government's deficit spending forces it to borrow new money simply to cover the interest on existing debt, it enters a self-perpetuating "debt death spiral." This weakens the nation's financial position until it either defaults or is forced to make brutal, unpopular cuts, risking internal turmoil.
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.'
