Tools RBI uses to contain inflation:

Cash Reserve Ratio This is the portion of funds that banks have to retain with the Reserve Bank. When the RBI increase this percentage, the amount actually available with the commercial banks comes down The RBI increases the CRR to draw out exess money from the banking system and thus check increase in prices. Bank Rate This is the rate at which the BRI lends to other banks. If the RBI increase its lending rate, the ripple effect will be felt across all the other banks that will hike lending rates to continue making profits. Repo Rate If banks face any shortfalls of funds they borrow from the RBI. Repo rate is the rate at which banks borrow money from the RBI. If the RBI reduces repo rates, it will be cheaper for the banks to borrow money. On the other hand, if repo rates go up, borrowing becomes expensive. Reverse Repo Rate: The RBI can borrow money from the banks and offer them a lucrative rate of interest. This is called the reverse repo rate and banks will be very glad to have their money with the RBI for a good interest rate as the money is safe here. When the reverse repo rate is increased, banks find it more attractive to park their money with the RBI, and hence money is drawn out of the system.
