Monetary policy operates with a 12-18 month lag, whereas the inflationary effects of oil shocks are immediate and front-loaded. By the time interest rate changes impact the economy, the initial inflationary pressure from oil has passed, making a policy response ineffective and potentially harmful.

The Fed uses slow, imprecise methods like household surveys to measure key inflation components like rent. This creates a significant lag, causing them to be late in both recognizing rising inflation (as in 2021) and seeing its decline, resulting in harmful policy errors and misallocation of trillions.

The inflationary impact from the Middle East war will persist well beyond initial gasoline price hikes. Secondary effects on airline fares, diesel fuel, transportation, and agricultural inputs will continue for months, eventually causing an acceleration in core CPI, not just the headline figure.

Investors often rush to price in the disinflationary outcome of an oil shock (demand destruction). However, the causal chain is fixed: prices rise first, hitting real spending. Only much later does this weaken the labor market enough to reduce overall inflation, a process that can take 9-12 months to play out.

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.

Kevin Warsh's confirmation hearings suggest a potential regime change at the Fed. He has indicated possible shifts in how inflation is measured (using trimmed mean), the size of the balance sheet, and a reduction in market communication like forward guidance.

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.

Kevin Warsh expresses skepticism about the Fed's reliance on real-time data, forecasts, and complex economic models, which he argues are often wrong and create a false sense of precision. This suggests a preference for a more principles-based monetary policy framework over a reactive, data-driven one.

The Fed's rate policy is driven by flawed data. The BLS's shelter inflation component has a built-in six-month delay and uses outdated collection methods. Real-time data shows inflation is already at target, meaning current high rates are unnecessarily damaging the economy.
