01

The missing comparison

A headline describes an outcome. A market interpretation often concerns the difference between that outcome and what participants had expected. Those are separate comparisons. Before explaining a reaction, identify the baseline: a survey consensus, an implied market path or an assumption made by the commentator. They are not necessarily the same.

02

There may be more than one surprise

A policy announcement can leave the current rate unchanged while changing the explanation of the outlook. An economic release can match its headline expectation while revising prior months or changing the composition. The relevant information set is a package, not always a single number.

03

Expectations are not directly visible in one price

A market price can reflect several influences. Even when a particular instrument is used to infer an expected path, its interpretation depends on assumptions. Avoid describing the market as a single person with one perfectly observable forecast. Name the evidence used for the expectation claim.

04

Communication changes the path question

Forward guidance communicates information about future policy intentions based on the institution’s assessment. Its conditions and horizon matter. A statement about what would happen if a condition is met differs from an unconditional commitment. Read the complete sentence and the surrounding explanation.

05

A disciplined post-release note

Separate three lines: what was published, what changed relative to the chosen baseline, and what happened in the market over a defined window. Then explain the mechanism as an interpretation. If the evidence does not isolate one cause, preserve that uncertainty rather than converting a plausible story into an established fact.

HYPOTHETICAL / A THOUGHT EXPERIMENT

One outcome, two baselines

Imagine a hypothetical rate decision of 4%. An observer who expected 4% sees no surprise in the level; one who expected 4.25% does. Neither baseline can be assumed to represent every market participant. The useful question is which expectation measure the analysis is actually using.

A QUICK CHECK

A decision is unchanged but the expected future path shifts. Is “nothing happened” a complete reading?

Keep the language clear Three useful definitions

Forward guidance — Central-bank communication about the possible future course of policy. Its meaning depends on the stated conditions and the institution’s framework. Read more ↗

Conditional forecast — An outlook calculated under specified assumptions. Changing the assumptions can change the outlook; the forecast is not an unconditional commitment. Read more ↗

Policy differential — A difference between policy settings or expected paths in two economies. Specify both economies and the horizon; current rates and expected future rates are not interchangeable. Read more ↗
