If the Central Bank increases its bank rate, it means that it raises the interest rate that it charges banks for borrowing money. This can have several effects on the economy. First, it can make it more expensive for banks to borrow money, which can reduce the amount of money that banks have available to lend to customers. This can cause the supply of money to decrease, which can lead to higher interest rates and less borrowing by consumers and businesses. Second, the higher interest rate charged by the Central Bank can lead to higher interest charges by commercial banks on loans and mortgages, which can discourage borrowing by customers. Overall, an increase in the Central Bank's bank rate can help to control inflation by reducing the supply of money in the economy, but it can also have a negative impact on borrowing and economic growth.
