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.
If the central bank raises its policy rate from 6.0% to 6.5%, banks usually raise their loan and deposit rates soon after, making home loans and business borrowing more expensive.
A higher policy rate makes borrowing costlier. Central banks usually raise rates to bring down high inflation. Higher rates can slow spending and investment.
A lower policy rate makes borrowing cheaper and is usually used to support growth when the economy is weak or inflation is low.
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.
