Bank rate is the key policy interest rate set by a central bank and used as a benchmark for monetary conditions in the wider economy.
Why it matters
Changes in the bank rate influence borrowing costs, saving incentives, asset prices, and exchange rates. Through those channels, the policy rate affects aggregate demand and inflation.
Economic transmission
When the central bank raises the rate, commercial funding costs usually rise and credit conditions often tighten. When it lowers the rate, financing conditions may ease and spending can be encouraged, though the strength of the effect depends on banking conditions and expectations.
More than one interest rate
The bank rate is not every market rate. It is a policy anchor. Market rates and retail lending rates may move with it, but not necessarily one-for-one.
