As the name suggests, #NBFCs (or Non-Banking Financial Companies) are not banks. CASA deposits or Current Account Savings Accounts are not used to raise funds by NBFCs. CASA deposits only apply to banks. The RBI issues licenses for the banks in order to accept money from the public. The #NBFCs don't have these prosperities. This means they need alternative sources of money supply that are higher than deposits made by banks where the interest rates offered range between 4% and 6%.
