Rajan suggests that a central bank's reluctance to aggressively fight inflation may stem from a fear of being blamed for a potential recession. In a politically charged environment, the institutional risk of becoming the 'fall guy' can subtly influence policy, leading to a more dovish stance than economic data alone would suggest.

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.

Central bankers are caught in a tug-of-war. The slow reaction to the 2022 energy shock taught them to act decisively against inflation by raising rates. However, intense political pressure may push them to keep rates low, creating a difficult choice between applying learned economic prudence and ensuring political survival.

Inflation from a supply disruption, like an oil price spike, will eventually fade. It only becomes persistent and embedded in the economy if governments try to 'help' consumers pay for higher costs with stimulus checks, which increases the broad money supply.

Current oil prices are stuck in a dangerous middle ground. They fuel inflation across the economy but aren't high enough to trigger the demand destruction that would force central banks into decisive action, creating a prolonged inflationary environment.

Every day the Federal Reserve fails to hike rates, it is effectively easing monetary policy. This inaction allows already loose financial conditions to continue stimulating the economy, creating significant inflationary pressure and pushing the Fed further behind the curve.

Policymakers, scarred by post-COVID inflation, risk tightening monetary policy excessively in response to energy price surges. History suggests these shocks are temporary and primarily affect headline, not core, inflation. The greater danger is stifling economic growth by overreacting to a transient inflationary impulse.

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.
