Economist Tyler Cowen argues that the market's muted reaction to the DOJ's investigation of Jerome Powell is because the Fed's independence was already compromised. The nation's high debt and deficits create implicit pressure to eventually monetize the debt through inflation, a structural force more powerful than political rhetoric.

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.

Governments with massive debt cannot afford to keep interest rates high, as refinancing becomes prohibitively expensive. This forces central banks to lower rates and print money, even when it fuels asset bubbles. The only exits are an unprecedented productivity boom (like from AI) or a devastating economic collapse.

In a democracy with massive debt, reckless government spending becomes inevitable. The electorate will consistently vote for short-term relief (money printing, free programs) over the long-term pain of austerity, making fiscal irresponsibility a predictable outcome of human nature.

The political hope is that AI-driven productivity will solve the national debt. The overlooked danger is that AI's first casualties will be highly-paid, indebted professionals (bankers, lawyers), whose mass defaults could crash the financial system before any 'age of abundance' arrives.

With debt-to-GDP at 130%, the implicit policy is to use inflation to devalue the debt burden. This is becoming explicit, with proposals like using tariff money for direct stimulus checks. This strategy favors risk assets and creates a 'full on euphoria tech bubble' if real yields go negative again.

Under "fiscal dominance," the U.S. government's massive debt dictates Federal Reserve policy. The Fed must keep rates low enough for the government to afford interest payments, even if it fuels inflation. Monetary policy is no longer about managing the economy but about preventing a debt-driven collapse, making the Fed reactive, not proactive.

The U.S. economy's only viable solution to its long-term debt and inflation is a "beautiful deleveraging"—a painful but controlled economic downturn. The alternative is delaying and being pushed off the cliff by market forces, resulting in a much more severe and uncontrolled crash.

The Fed is cutting rates despite strong growth and inflation, signaling a new policy goal: generating nominal GDP growth to de-lever the government's massive, wartime-level debt. This prioritizes servicing government debt over traditional inflation and employment mandates, effectively creating a third mandate.
