Forward Guidance Versus Surprise: Why Price Reacts to the Gap, Not the Decision
Posted: Mon Oct 26, 2026 12:44 pm
A central bank rate decision that matches expectations usually produces a muted reaction, because the outcome is already priced into currency and rates markets. The tradable event is the gap between what was priced and what is delivered, along with any change to the expected path.
Forward guidance is the tool that narrows that gap. Clear signals about future policy let markets adjust gradually in the weeks before a meeting, so the day itself can feel quiet. When guidance is vague, or when officials deliberately stress data dependence, the decision day carries more uncertainty and wider reactions.
Some of the largest moves arise not from the rate decision but from the statement tone and press conference. A currency may spike on the headline, reverse on a single phrase and settle in a different place by the end of the press conference. Initial direction on the decision candle is therefore a poor guide to the final one.
For scalpers, the useful habit is to compare market pricing, such as futures-implied expectations, against the central bank's own signals before the event. A small gap suggests limited reaction, while a large gap suggests spreads and slippage may be elevated.
