When the prevailing narrative, supported by Fed actions, is that the economy will 'run hot,' it becomes a self-fulfilling prophecy. Consumers and institutions alter their behavior by borrowing more and buying hard assets, which in turn fuels actual inflation.

Official inflation metrics (rate of change) are meaningless to the public. People feel the pain of absolute price levels versus their stagnant wages, creating a disconnect that fuels widespread economic apathy and anger, regardless of what government data says.

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.

While the direct impact of tariffs may be temporary, the elongated process risks making consumers and businesses comfortable with higher inflation. Combined with questions about the Federal Reserve's political independence, this could unmoor expectations and make inflation persistent.

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.

History suggests that if inflation remains high for too long, it can alter public psychology. Businesses may become less hesitant to raise prices, and consumers may grow more accepting of them. This shift can create a self-perpetuating feedback loop, or 'snowball' effect, making inflation much harder for the central bank to control.

Official inflation metrics may be low, but public perception remains negative because wages haven't kept pace with the *cumulative* price increases since the pandemic. Consumers feel a "permanent price increase" on essential goods like groceries, making them feel poorer even if the rate of new inflation has slowed.

While a single tariff hike is a one-time price shock, a policy of constantly changing tariffs can become a persistent inflationary force. The unpredictability de-anchors inflation expectations, as businesses and consumers begin to anticipate a continuous series of price jumps, leading them to adjust wages and prices upwards in a self-reinforcing cycle.

The longevity of above-target inflation is a primary concern for the Fed because it can fundamentally alter consumer and business behavior. Historical models based on low-inflation periods become less reliable. Businesses report being surprised that consumers are still accepting price increases, suggesting pricing power and inflation expectations may be stickier than anticipated.
