Class 12 Economics - ISC
Money and Banking
The 'Money and Banking' chapter in Class 12 ISC Economics explores the evolution of money, its primary and secondary functions, and how commercial and central banks create and regulate credit. Understanding money supply measures (M1, M2, M3, M4) and the functioning of the Reserve Bank of India (RBI) through quantitative and qualitative credit control tools is crucial. This chapter forms the foundation of macroeconomics, consistently carrying substantial weight in the ISC board examinations through both theoretical and numerical problems on money multiplier and credit creation.

Frequently Asked Questions
What is the difference between CRR and SLR?
CRR (Cash Reserve Ratio) is the fraction of deposits that commercial banks must keep with the Central Bank (RBI), whereas SLR (Statutory Liquidity Ratio) is the fraction banks must maintain with themselves in liquid assets like approved securities.
How does an increase in the Repo Rate control inflation?
An increase in the Repo Rate makes borrowing expensive for commercial banks. They pass this cost to the public by raising lending rates, which reduces borrowing, lowers aggregate demand, and helps control inflation.
Why are savings and time deposits not included in M1?
M1 includes only the most liquid forms of money (currency and demand deposits) that can be used directly for transactions. Time and savings deposits have restrictions on immediate withdrawal and are less liquid.
