Overview
This series explains when a central bank can treat an energy-price surge as a temporary first-round shock and when persistence, pass-through, expectations, or activity damage make earlier action more defensible. It moves from supply-and-demand diagnosis through core inflation and country differences to the Federal Reserve’s time-stamped 2026 case, ending with a conditional rule rather than a universal rate threshold.
Learning outcomes
- Looking through is defensible only when the energy movement is likely to reverse or remain contained before policy works.
- Large supply-driven energy increases can have disproportionately larger and longer-lasting core-inflation effects than smaller shocks.
- Import dependence, energy intensity, exchange rates, fiscal policy, and starting expectations change the policy trade-off across economies.
- The evidence supports conditional updating, not a universal rate threshold or a one-size-fits-all response.

PlansFAQ
When should a central bank look through an energy shock?
A central bank should look through it when a temporary first-round movement is likely, broader inflation and expectations remain contained, and activity damage is manageable.
Why can an energy shock raise inflation and weaken the economy at the same time?
An energy shock raises direct prices and firms’ costs while reducing households’ real income and, potentially, production, consumption, and employment.
How does an energy-price increase become core inflation?
It becomes broader inflation when firms, workers, households, or fiscal measures reinforce the initial cost increase through prices, wages, demand, or expectations.
Why do countries respond differently to the same energy shock?
Countries differ because import dependence, export income, energy intensity, exchange rates, fiscal policy, and starting inflation conditions change pass-through and activity damage.
