Euro Area Interest Rate

Understanding Interest Rate — a simple guide

What it measures

The central bank’s main policy rate — the rate at which it lends to, or pays, commercial banks. It anchors short-term borrowing costs across the economy.

How it is calculated

This is not calculated from a formula — it is decided by the central bank’s monetary policy committee at scheduled meetings. The figure shown is the official policy rate at the end of each month.

Why it matters for the economy and markets

Policy rates influence loan and deposit rates, bond yields, currency values and the discount rate investors apply to future earnings. Changes are among the most closely watched events in financial markets.

How to read it

Look at the direction and pace of changes as well as the level. Comparing the policy rate with inflation gives the “real” rate: a policy rate above inflation is generally considered restrictive, below it accommodative.

What to look at alongside it

Inflation (to calculate the real interest rate), bond yields, currency movements and bank lending growth.
