Open-Market Rate

The open-market rate is the interest rate at which banks lend money to each other overnight. It is set by the central bank and is used as a benchmark for other interest rates in the economy.

The open-market rate is important because it affects the cost of borrowing for businesses and individuals. When the open-market rate is low, it is cheaper for businesses and individuals to borrow money, which can lead to increased economic activity. Conversely, when the open-market rate is high, it is more expensive for businesses and individuals to borrow money, which can lead to decreased economic activity.

The central bank uses the open-market rate to manage the money supply and control inflation. When the central bank wants to increase the money supply, it lowers the open-market rate. This makes it cheaper for banks to borrow money from the central bank, which they then lend to businesses and individuals. The increased lending leads to an increase in the money supply. Conversely, when the central bank wants to decrease the money supply, it raises the open-market rate. This makes it more expensive for banks to borrow money from the central bank, which they then lend to businesses and individuals. The decreased lending leads to a decrease in the money supply.

The open-market rate is also used as a benchmark for other interest rates in the economy. For example, the prime rate is typically set at a fixed margin above the open-market rate. The prime rate is the interest rate that banks charge their most creditworthy customers. Other interest rates, such as mortgage rates and credit card rates, are often based on the prime rate.

The open-market rate is a key tool that central banks use to manage the economy. By carefully setting the open-market rate, central banks can influence the cost of borrowing, the money supply, and inflation.
