Frequently Asked Questions
What is the difference between Commercial Bank and Central Bank?
A commercial bank aims to earn profit by accepting public deposits and advancing loans to households and firms, whereas the central bank (RBI) is the apex institution that regulates the entire banking system, controls money supply, and does not deal directly with the general public.
How does Central Bank control inflation using Repo Rate?
During inflation, the Central Bank increases the Repo Rate, making borrowings expensive for commercial banks. Banks in turn raise lending rates for the public, reducing credit demand, aggregate demand, and ultimately bringing down inflation.
What is Legal Reserve Ratio (LRR)?
LRR is the minimum fraction of total deposits that commercial banks are legally required to keep with themselves (as Statutory Liquidity Ratio) and with the Central Bank (as Cash Reserve Ratio) before they can lend out money.
