Interest rate decision


Family IX · Macro

Not to be confused with exchange rate, floating exchange rate, inflation rate.

Interest rate decision is the formal announcement by a central bank's monetary policy committee of the target level for its policy interest rate, or of a change to that level, following a scheduled or ad hoc policy meeting. The decision sets the rate at which the central bank lends to or borrows from commercial banks, which in turn anchors short-term market rates. It is typically published with a statement explaining the reasoning and, in many jurisdictions, a vote breakdown.[1]

What the decision contains

A rate decision usually consists of three parts: the new target level for the policy rate, the size of any change from the previous level, and the accompanying statement or minutes. The target level may be expressed as a single figure or as a range, depending on the central bank. The statement often includes forward guidance about future policy, though the wording and the extent of that guidance vary by institution.

Decisions are taken by a committee, such as a rate-setting council or board, and the vote is often published. The frequency of scheduled meetings varies by central bank, commonly between six and twelve times a year, and an unscheduled decision can occur in exceptional circumstances.

Worked example

Suppose a central bank's policy rate is 4.50% and the committee votes to raise it by 25 basis points.

EFFECT OF A 25 BASIS POINT HIKE
Previous policy rate4.50%4.50%
Change+0.25 percentage points+25 basis points
New policy rate4.50% + 0.25%4.75%

The new target is 4.75%. Market rates such as the overnight interbank rate typically adjust toward this level, though the speed and completeness of the pass-through depend on liquidity conditions and the operating framework.

An interest rate decision is an action by a central bank, not a market price. It is distinct from the exchange rate, which is the price of one currency in terms of another. A floating exchange rate is a regime in which that price is determined by market supply and demand, rather than a policy announcement. The inflation rate is a measure of the change in the general price level, often the target that motivates a rate decision but not the decision itself.

Often confused with

exchange rate
An exchange rate is a market price for one currency against another, while an interest rate decision is a policy announcement by a central bank; the visible sign is that an exchange rate is quoted as a pair such as EUR/USD, whereas a rate decision is stated as a target percentage.
floating exchange rate
A floating exchange rate is a currency regime in which the price is set by trading, while an interest rate decision is a specific policy action; the visible sign is that a floating rate changes continuously during market hours, whereas a rate decision changes only at scheduled or emergency announcements.
inflation rate
The inflation rate measures the change in consumer prices over time, while an interest rate decision sets a policy rate; the visible sign is that inflation is reported as an annual or monthly percentage change in a price index, whereas a rate decision is reported as a target level for the policy rate.
