Historically, surges in U.S. public debt have consistently led to periods of negative real interest rates. This suggests that the sheer weight of government debt creates a structural constraint, forcing markets to keep real rates capped, irrespective of short-term inflation or central bank policy.

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.

In a world where the government is the largest debtor, raising interest rates acts as a fiscal transfer, increasing income for the private sector (bondholders). When this is financed through monetized bill issuance, higher rates can paradoxically become an economic stimulus, not a contractionary force.

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.

The Fed's tool of raising interest rates is designed to slow bank lending. However, when inflation is driven by massive government deficits, this tool backfires. Higher rates increase the government's interest payments, forcing it to cover a larger deficit, which can lead to more money printing—the root cause of the inflation in the first place.

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.

Traditional monetary policy tools like interest rate hikes are poorly suited to combat modern inflation drivers. They fail to address price pressures from specific industrial booms (e.g., AI memory chips) or the inflationary effects of large, persistent government deficit spending.

The massive increase in government debt held privately has broken the monetary policy transmission mechanism. When the Fed raises rates, the private sector's interest income from Treasury holdings now rises significantly, creating a stimulus that counteracts the tightening effect on borrowing costs.

With federal debt at high levels, raising interest rates creates a massive fiscal transfer. The government's interest expense, now over a trillion dollars, becomes income for bondholders. This stimulatory effect for the wealthy can counteract the intended tightening, while simultaneously hurting lower-income individuals who need to borrow.
