The key rate is a benchmark interest rate that plays a crucial role in the financial system by determining bank lending rates and the cost of credit for borrowers. Central banks use the key rate as a primary tool to control monetary policy, influence economic activity, and maintain financial stability.
Definition

It impacts the rates at which banks lend to each other overnight and, consequently, the rates they charge consumers and businesses for loans.
