Money and Banking

While barter system limitations like double coincidence of wants are elementary, focus on how fiat money differs from legal tender and commodity money. Note that legal tender is backed by law and cannot be refused for settlement of transactions, a definition tested by UPSC in 2018. Skip long historical anecdotes on shell money, but memorize the distinction between token money and full-bodied money as UPSC traps students on intrinsic vs face value.

Highly critical for understanding liquidity preference theory. Pay close attention to speculative demand for money, which has an inverse relationship with the interest rate—creating a liquidity trap at ultra-low rates. Memorize the exact formulas for money aggregates: M1 (narrowest, most liquid) to M4 (broadest). High-powered money (H) or reserve money consists of currency with the public, vault cash, and bank deposits with RBI. UPSC frequently tests the impact of cash withdrawals on M1 and money supply (e.g., gs1-2020-50).

Explains credit creation, the deposit multiplier (1/LRR), and the money multiplier. Note that LRR consists of CRR and SLR. The money multiplier formula (M/H) is a favorite UPSC theme (e.g., 2019, 2021). Students must understand how changes in banking habits (like digital transactions) or cash-to-deposit ratios affect the multiplier. Skip complex accounting ledger balances but thoroughly master how a single deposit generates multiple credit expansions.

Crucial core of monetary policy. Distinguish clearly between quantitative tools (CRR, SLR, Repo, Reverse Repo, MSF, Bank Rate, Open Market Operations) and qualitative tools (margin requirements, moral suasion). Note that CRR is kept as cash with RBI, earning no interest, while SLR can be held in gold, cash, or government securities (G-Secs). Understand how RBI sterilizes foreign exchange inflows using market stabilization schemes. UPSC tests expansionist vs contractionary monetary stances (e.g., gs1-2020-57).
