The Federal Reserve is forced into a hawkish, inflation-fighting stance because the labor market and stock market are strong while inflation remains above target. This situation removes any justification for easing policy, making inflation the sole focus.

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.

Geopolitical instability has altered the Federal Reserve's response function. Morgan Stanley economists believe the Fed now requires a more significant oil price shock to trigger a resumption of rate hikes than previously anticipated, suggesting a higher tolerance for energy-driven inflation.

The primary inflation risk isn't a single event, but the compounding effect of multiple transient shocks (e.g., wars, tariffs). When these occur too frequently, businesses and consumers begin to perceive them as a permanent feature of the economy, leading to un-anchored inflation expectations even if the underlying causes are temporary.

While events like the pandemic, the Ukraine war, and the Iran conflict are individually unique, their rapid succession conditions the public to expect continuous price shocks. This transforms transitory inflation into a deep-rooted psychological problem for central banks, as people stop seeing these events as isolated.

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.

It's the volatility and unpredictability within the supply chain environment—rather than the magnitude of a single shock—that can dramatically amplify the inflationary effects of other events, like energy price spikes. This suggests central banks need situation-specific responses.

Pessimism on inflation is warranted because common analysis misses key factors. Household inflation expectations are becoming unanchored, the overall economy is tight based on the output gap (not just unemployment), and the "new normal" is a state of recurring supply shocks, not a return to pre-shock stability.

Policymakers have transitioned from a world where 2% inflation was a ceiling to one where it's a floor. The primary battle is no longer preventing inflation from rising above 2%, but rather struggling to bring it down to 2%, which is now seen as the bottom of the acceptable range.
