A significant disconnect is emerging between Fed policy and inflation data. The Federal Reserve is signaling a dovish shift, prioritizing labor market risks and viewing inflation as transitory, even as forecasts show both headline and core inflation accelerating into the fourth quarter.

Faced with a stagflationary shock, the Federal Reserve is on hold. Its next move will be dictated by inflation *expectations*, measured by the 5-year breakeven rate. If expectations remain anchored, the Fed can focus on growth; if they rise, aggressive rate hikes will follow.

The Federal Reserve's practice of pre-committing to low interest rates (forward guidance) hindered its ability to react swiftly to rising inflation in 2021. This policy trap caused the Fed to be late in raising rates, allowing the economy to overheat and inflation to take hold, a mistake the new leadership seeks to avoid.

The Fed's concern isn't just the current high inflation rate, but the risk that prolonged high inflation changes public psychology. If businesses and consumers begin to expect continued price hikes, they may become less price-sensitive, creating a self-reinforcing 'snowball' effect that makes inflation much harder to control.

By choosing inaction over rate hikes or hawkish communication, the Fed is betting that inflation will moderate on its own in the near future. If this gamble fails and inflation remains high, the Fed will face a significant credibility challenge and be forced to take more aggressive action later.

The Federal Reserve is no longer willing to 'look through' one-time supply shocks causing inflation. After a prolonged period of high inflation from various sources (tariffs, war, AI demand), the FOMC signals it will act to prevent high inflation expectations from becoming permanent, regardless of the original cause.

The textbook response to supply-shock inflation is to "look through" it and hold rates. However, one expert argues that after five years of high inflation, the sheer duration creates a risk of it becoming embedded. This "duration risk" could override the cause, forcing the Fed to tighten policy as a risk management measure.

The Federal Reserve can tolerate inflation running above its 2% target as long as long-term inflation expectations remain anchored. This is the critical variable that gives them policy flexibility. The market's belief in the Fed's long-term credibility is what matters most.

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.
