Interest Rate Decisions

A central bank's policy interest rate is the rate at which it lends to (or influences lending within) its own banking system. When it rises, it generally pulls a currency higher over time; when it falls, it generally pushes the currency lower. Nearly every other release on this list matters mainly because of how it changes expectations about what the central bank will do with this rate next.

Central banks move markets through language as much as through the rate decision itself. A "hawkish" tone (leaning toward raising rates, or holding them higher for longer) tends to strengthen a currency even with no rate change that day; a "dovish" tone (leaning toward cutting, or holding lower for longer) tends to weaken it. This is why a press conference with an unchanged rate can still move markets sharply -- the words are the news.

Suppose a central bank holds its rate unchanged, exactly as expected -- but its statement drops previous language about "further tightening may be needed" and instead says policy is "well positioned," widely read as a signal it's done hiking. Even with zero actual change to the rate, that shift in guidance can weaken the currency meaningfully, since it reprices what the market expects for the next several meetings, not just this one.
