Forward guidance and stated rationale: language about the future, read factually

Why it matters

The newest FOMC brief cites a sentence from the statement of 2026-09-16 that looks forward: "The Committee will deliver price stability.". It also cites the sentence that gives the reason for the decision: "Inflation remains elevated.". Beside them, the brief holds the previous statement of 2026-07-29, whose own language preceded the current decision. A reader who takes the forward-looking sentence as a promise will expect the next meeting to deliver it. Why it is not a promise, and how the record shows that, is the idea here.

The concept

A central-bank statement contains sentences of three kinds around the decision. Assessment sentences describe what the committee sees: activity, employment, inflation, uncertainty. Rationale sentences say why it acted as it did at this meeting, often by naming the goal the action serves. Guidance sentences say what the committee expects to do and what it will weigh in doing it. Kitalpha’s brief cites each sentence as an attributed span and tags it by type, so the three kinds can be counted and read separately from the decision sentence and the vote.

Forward guidance is the kind most often misread, because it uses the future tense. The committee says it “will” deliver an objective, or that it “will assess” incoming information, or that it “anticipates” a course of action. Each of these is a statement about the committee’s own intentions under conditions it names, made by a body that meets again in six or seven weeks and decides afresh. Guidance describes a reaction function: given such conditions, this is how we expect to respond. It is not a decision, it is not a forecast of the economy, and it binds nothing. Its value is that it tells a reader what the committee says it will look at, which is different from telling the reader what will happen.

Stated rationale is the backward-looking counterpart. When the committee writes that an action supports its goal being reached sooner, or that it acted in view of the balance of risks, that sentence explains the decision just taken, and it is dated by the meeting that took it. It is the committee’s own account of its reasons, which the brief quotes verbatim rather than paraphrasing; it is not a claim about the next meeting.

The record itself is the best corrective. The brief cites the previous statement’s decision sentence from its own dated source, and the current statement’s decision sentence from its. Between the two, the guidance language may have barely changed while the decision changed in size or direction, because the conditions the guidance was conditional on changed. Setting the two decisions side by side, and reading the earlier guidance in between, shows in the plainest way that guidance preceded a fresh decision rather than fixing it.

Two habits follow. Read a guidance span as a description of intent with its conditions attached, and read a rationale span as the committee’s explanation of the action already taken. The table below sets one sentence of each kind beside the decision sentence from the newest brief. Look for which row is an action, and notice that the other three, however forward-looking their tense, are descriptions.

Worked example

Take the newest FOMC brief. The steps below count its attributed spans by the type the brief tags them with: assessment, rationale and guidance, out of all spans cited from the current statement; then take the share of spans that look forward, and read the size of the move the decision sentence records. Every figure comes from the brief’s own record.

What to read off the steps. The fifth line is the share of the statement’s cited sentences that describe the committee’s intentions rather than conditions, reasons or the decision; it is small, which is the first thing to know about a document that readers often treat as a set of promises. The last line is what the statement did. The faded example places it against the previous statement’s decision, which is the comparison that shows what the earlier guidance language actually preceded.

Faded example

Now the previous statement as the brief cites it, dated 2026-07-29, whose decision sentence reads: "The Committee decided to maintain the target range for the federal funds rate at 3-1/2 to 3-3/4 percent, in support of the Federal Reserve's dual mandate.". The upper limit of its range and the upper limit in the current decision are given. Complete the last step: the change between them in basis points.
