Rate decisions land at 14:00 ET, eight times a year. Minutes follow three weeks later. There is nothing to be surprised by — and it is still the hardest-moving class on the calendar.
The Federal Open Market Committee sets the target range for the federal funds rate. Eight scheduled meetings a year, each producing a statement, and at quarterly meetings a Summary of Economic Projections — the "dot plot" showing where each member expects rates to go.
Minutes of each meeting are published three weeks later.
By the meeting date the decision itself is typically priced with high confidence. What is not priced is the framing — how close the vote was, what conditions would change it, and how the risks are characterised.
That framing moves the expected path of rates, which moves real yields, which is gold's opportunity cost.
Assuming no surprise means no movement.
No consensus forecast exists for a text release, so there is no surprise figure to compute at all. Yet minutes routinely produce some of the largest ranges on the calendar.
A release with nothing to be surprised by can still reprice the entire curve. Surprise and impact are separate ideas, and conflating them is how people size a text release as if it were quiet.
The dot plot at quarterly meetings, and any change in how the risks are described. A single reworded sentence can move rate expectations more than the decision itself.
In the minutes, the distribution of opinion matters: a unanimous decision and a narrow one imply very different odds for the next meeting.
