Fed Chair Jerome Powell explains the framework for responding to energy price shocks (e.g., oil), which are supply shocks.
States monetary policy tools primarily work on aggregate demand, not supply, and act with "long and variable lags."
Argues the historical tendency is to "look through" transient supply shocks because by the time tighter policy impacts the economy, the shock may have passed, creating inappropriate economic drag.
Emphasizes a critical condition for this approach: the central bank must "carefully monitor inflation expectations."
Warns that repeated supply shocks can cause the public and businesses to adjust their long-term inflation expectations upward.
Notes that in the current context, inflation has been coming down post-pandemic but has not yet stabilized at the 2% target.
States that, for now, longer-term inflation expectations "appear to be well anchored."
Indicates the Fed is not currently facing a decision on how to respond to the latest geopolitical-driven energy shock, as the economic effects are still unknown.
Concludes that when a decision is necessary, the Fed will be "mindful of that broader context" of not having firmly reached 2% inflation.
