Central Bank Speeches and Forward Guidance
Policy is a path, not a single decision, and speeches are where the path gets revised without anything being announced.
Central bank speeches move markets because exchange rates are priced off the expected path of interest rates, not today's rate. When an official changes the language describing conditions, the market reprices that path immediately. A single altered clause can take an expected rate cut from 38% priced to 71% priced, move the two-year yield 14 basis points and shift a currency 90 pips, with no policy decision taken at all.
What to remember
- Nothing has to be announced for a speech to move price. Repricing the expected path is enough, because currencies trade off the differential across that path.
- The information is in the deviation from that speaker's own baseline. A known hawk sounding cautious is a larger event than a known dove repeating himself.
- Prepared text and question time are two separate risks. The unscripted answer that moves price often arrives twenty-five minutes after the text.
- A blackout period of seven to ten days before a decision clusters speech risk into the weeks between meetings and pushes sourced stories into the quiet window.

Central bank speeches move markets because policy is a path rather than a single decision, and speeches are where the path gets revised. An official who changes one clause can reprice an entire rate curve without anything being announced that day, which is why a scheduled testimony sometimes produces a larger move than the meeting it precedes.
A 38% chance became 71%, and nothing was announced
Here is the shape of it in numbers. The morning of a governor's testimony, interest rate futures price a 38% probability of a cut at the next meeting. In the prepared text the phrase "the committee can be patient" is gone, replaced by a line saying risks to the labour market have become two-sided. No decision was taken. No vote happened.
Within twenty minutes the same futures price a 71% chance of a cut, the two-year government yield falls 14 basis points, and the currency drops roughly 90 pips against the dollar. Ninety pips is more ground than EUR/USD covers in a normal full session, and on half a lot it is $450, produced entirely by a change in what the market expects rather than by anything that happened today. Put your own position size through the pip calculator and the reason speeches belong on your calendar becomes obvious.
Forward guidance is a description of conditions, not a promise
Forward guidance is an official signalling how the committee reads current conditions and what would have to change for policy to move. It works on price because an exchange rate is priced off the expected interest rate differential across the whole path, not off today's rate. Move the expected path down by 25 basis points over the next year and the currency reprices immediately, even though the current rate is untouched. This is the same mechanism covered in how forex prices move, applied to words instead of data.
The corollary is the part people miss. Guidance is conditional, so it can be withdrawn without anyone having lied. A committee that said it expected to hold rates through the year is free to cut in March if the data changes, and the market knows this, which is why guidance moves price by degrees rather than absolutely.
