What portion of bank deposits are kept by banks for day-to-day transactions?
Answers
Banks in India are required to hold a certain proportion of their deposits in the form of cash. However Banks don't hold these as cash with themselves, they deposit such cash(aka currency chests) with Reserve Bank of India , which is considered as equivalent to holding cash with themselves. This minimum ratio (that is the part of the total deposits to be held as cash) is stipulated by the RBI and is known as the CRR or Cash Reserve Ratio.
When a bank's deposits increase by Rs 100, and if the cash reserve ratio is 9%, the banks will have to hold Rs. 9 with RBI and the bank will be able to use only Rs 91 for investments and lending, credit purpose. Therefore, higher the ratio, the lower is the amount that banks will be able to use for lending and investment. This power of Reserve bank of India to reduce the lendable amount by increasing the CRR, makes it an instrument in the hands of a central bank through which it can control the amount that banks lend. Thus, it is a tool used by RBI to control liquidity in the banking system.
