What Inflation Data Actually Tells Us, and What It Doesn't
Headline inflation is a summary statistic, not a verdict. A short guide to reading the components that drive policy.
By Ali Wardhere
Every inflation release triggers the same ritual: a single number, a flurry of reaction, a forgotten nuance. Yet the headline figure is an average of very different stories.
Core versus headline
Stripping out food and energy is not a trick to flatter the data. It isolates the persistent component policymakers can actually influence. Energy spikes fade; services inflation tends to stick.
The composition matters
Two economies can print the same inflation rate while facing opposite problems. One driven by wages and services is a very different policy challenge than one driven by a one-off supply shock.
