The Federal Reserve's anticipated rate cuts are not merely a response to cooling inflation but a deliberate 'insurance' policy against a weak labor market. This strategy comes at the explicit cost of inflation remaining above the 2% target for a longer period, revealing a clear policy trade-off prioritizing employment over price stability.

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.

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.

While current events may push the economy in a stagflationary direction (higher prices, slower growth), it's crucial to distinguish this from actual stagflation. Goolsbee notes that the 1970s saw unemployment and inflation rates both near or above 10%, a scenario far more severe than today's challenges.

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.

Single-mandate central banks like the ECB and BoE are trapped. They must react to oil-driven inflation with hawkish policy, even though their economies are most exposed to the energy shock's demand destruction, creating a stagflationary double whammy.

A single neutral interest rate may not exist. There could be one R-star for the investment-heavy AI sector and another for housing. A separate R-star might even be needed for financial stability. This divergence means the Fed faces a policy trade-off where a rate that balances one part of the economy could destabilize another.

Central bank credibility is a finite resource. By not fully stamping out inflation to its 2% target, the Fed depletes its credibility, making the next inflationary shock harder and more costly to control—a lesson from the recurring inflation of the 1980s.

When oil prices spike, they create widespread inflation. This prevents the Fed from using its primary tool—cutting interest rates—to help a struggling economy, as doing so would risk runaway inflation. The Fed is effectively caged until oil prices fall, leaving the market without its usual safety net.
