Unit 13: Monetary Policy

Monetary policy is the process by which a central bank regulates the supply, cost and availability of money and credit to achieve declared macroeconomic goals. In India it is conducted by the Reserve Bank of India (RBI, established 1935), and since the RBI Act amendment of 2016 it is anchored by a statutory inflation-targeting framework operated through a Monetary Policy Committee (MPC).

• Authority: The central bank, not the government, executes monetary policy; the RBI acts as the monopoly issuer of currency and banker to banks.
• Instrument variable: The policy lever is the short-term interest rate (the repo rate) and the quantity of reserves in the banking system.
• Target variable: The ultimate targets are price stability, output and employment; the operating target is the weighted average call money rate.
• Transmission chain: Policy rate → bank lending rates → investment and consumption → aggregate demand → output and prices.
• Nature: It is a demand-side stabilisation tool, complementary to fiscal policy, and works with a time lag of several quarters.

II. Concept and Meaning

The concept of monetary policy centres on deliberate control of monetary aggregates to influence real economic activity.

A. Concept and meaning

Monetary policy is defined as the central bank's management of money supply and interest rates to attain stated objectives.

• Core definition: Regulation of the cost of credit (interest rate) and volume of credit (money supply) by the monetary authority.
• Money supply measures: Framed in terms of monetary aggregates — M1 = currency + demand deposits, M3 = M1 + time deposits, where M3 is the broad money the RBI monitors.
• Two stances:
  1. Expansionary (easy money): Raising money supply and cutting rates to fight recession, e.g. cutting the repo rate to spur borrowing.
  2. Contractionary (tight money): Reducing money supply and raising rates to curb inflation, e.g. hiking the repo rate to dampen demand.
• Basis of action: Rests on the quantity theory link MV = PY, where M = money supply, V = velocity, P = price level, Y = real output; changing M alters P or Y.
• Distinction from fiscal policy: Monetary policy uses money and credit; fiscal policy uses government taxation and spending.

III. Objectives

Monetary policy pursues several goals that are often in tension, requiring the central bank to prioritise among them.

A. Objectives

The objectives specify what outcomes the manipulation of money and credit is meant to deliver.

• Price stability: Keeping inflation low and steady; the current Indian target is 4% CPI inflation ± 2%, the primary objective since 2016.
• Economic growth: Ensuring adequate credit to productive sectors so investment and output expand without overheating.
• Full employment: Supporting aggregate demand to raise employment toward its natural level.
• Exchange rate stability: Managing external value of the rupee to protect trade competitiveness and capital flows.
• Balance of payments equilibrium: Influencing interest rates to attract or moderate capital inflows and correct external imbalances.
• Financial stability: Maintaining orderly conditions in money and credit markets so that banks remain solvent and liquid.
• Conflict among goals: Growth and price stability can clash — cheap credit spurs output but risks inflation; the MPC resolves this by placing price stability first while keeping growth "in mind."

IV. Tools of Monetary Policy

The tools are the operational instruments through which the central bank alters liquidity and credit; they divide into quantitative (general) and qualitative (selective) controls.

A. Tools of monetary policy

The RBI uses instruments that either change the quantity of money economy-wide or channel credit to specific uses.

• Quantitative (general) tools: Affect the total volume of credit.
  • Repo rate: The rate at which the RBI lends short-term to banks against securities; a cut lowers banks' funding cost and lending rates.
  • Reverse repo rate: The rate at which the RBI absorbs surplus funds from banks; raising it withdraws liquidity.
  • Bank rate: The long-term lending/discount rate of the RBI, a signalling and penal rate.
  • Cash Reserve Ratio (CRR): The fraction of net demand and time liabilities banks must hold as cash with the RBI; a rise in CRR reduces lendable funds directly.
  • Statutory Liquidity Ratio (SLR): The share of liabilities banks must hold in cash, gold or approved securities; raising SLR shrinks credit capacity.
  • Open Market Operations (OMO): RBI's outright purchase or sale of government securities; buying securities injects liquidity, selling drains it.
  • Marginal Standing Facility (MSF): An emergency overnight window above the repo rate for banks short of funds.
• Qualitative (selective) tools: Direct credit toward or away from particular sectors.
  • Margin requirements: The gap between a loan and the collateral value; a higher margin curbs speculative borrowing against stocks or commodities.
  • Credit rationing: Setting ceilings on credit to specific sectors.
  • Moral suasion: Informal persuasion and advice to banks to comply with policy.
  • Direct action: Penalties or refusal of accommodation to non-complying banks.
• Corridor logic: The repo, reverse repo and MSF form the Liquidity Adjustment Facility corridor within which the call rate is steered.

Worked illustration of CRR

Bank deposits (NDTL)      = 1000
CRR                       = 4%   -> reserves locked = 40, lendable = 960
Money multiplier          = 1/CRR = 1/0.04 = 25
If CRR rises to 5%        -> multiplier = 1/0.05 = 20
Potential money creation falls from 25x to 20x of reserves.

• Reading: A one-point CRR rise cuts the credit-creation multiplier, tightening liquidity without changing the policy rate.

V. Role of Monetary Policy After the Period of Economic Reforms

Economic reforms reshaped monetary policy from a rigid, direct-control regime into a market-based, transparent framework.

A. Role of monetary policy after the period of economic reforms

The 1991 liberalisation and subsequent reforms shifted the RBI from administered credit allocation toward indirect, rate-based management.

• From direct to indirect controls: Pre-1991 policy relied on high CRR/SLR and administered interest rates; reforms lowered SLR (from around 38.5%) and CRR sharply and freed most lending rates.
• Deficit financing curbed: Automatic monetisation of the fiscal deficit through ad hoc Treasury Bills was ended (1997), separating monetary policy from government borrowing.
• OMO and LAF as prime tools: After the Narasimham Committee reforms, open market operations and the Liquidity Adjustment Facility (introduced 2000) became the main instruments, replacing quantitative rationing.
• Multiple indicator approach: From 1998 the RBI tracked a range of variables — output, credit, trade, capital flows — rather than a single money-supply target.
• Financial market development: Reforms deepened the call money, government securities and forex markets, strengthening the interest-rate transmission channel.
• Inflation-targeting regime: The 2016 framework institutionalised the reform trajectory — a statutory 4% CPI target and a six-member MPC deciding rates by majority vote.
• External integration: With liberalised capital flows, policy now weighs exchange-rate movements and foreign investment, using sterilised intervention and the Market Stabilisation Scheme to manage inflows.

VI. Inflation and Monetary Policy

Inflation control is the central objective of modern monetary policy, and the relationship between the two defines the policy stance.

A. Inflation and monetary policy

Inflation, a sustained rise in the general price level, is combated primarily by monetary tightening that reduces excess demand.

• Types by cause:
  1. Demand-pull inflation: Too much money chasing too few goods; monetary policy responds directly by raising the repo rate and CRR to shrink demand.
  2. Cost-push inflation: Prices rise from higher input costs (oil, wages); monetary policy is weaker here since tightening cannot lower supply costs and may hurt output.
• Measurement anchors: India targets the CPI (Consumer Price Index); the WPI (Wholesale Price Index) is a supplementary gauge.
• Transmission of tightening: Higher repo rate → costlier loans → lower investment and consumption → falling aggregate demand → easing prices.
• Phillips-curve trade-off: In the short run lower inflation can mean higher unemployment, expressed as an inverse relation between inflation and joblessness; the RBI accepts some growth sacrifice to hold inflation near 4%.
• Real versus nominal rate: The stance depends on the real rate r = i − π, where i = nominal policy rate and π = expected inflation; a positive real rate signals genuinely tight policy.
• Anchoring expectations: A credible, pre-announced inflation target keeps household and firm expectations low, so wage and price setting stay moderate — the core rationale for statutory targeting.
• Limitations against inflation:
  • Lag effect: Rate changes take two to four quarters to bite.
  • Supply shocks: Food and fuel spikes are largely outside monetary control.
  • Fiscal dominance: Large government borrowing can offset tightening.
  • Transmission gaps: Banks may pass on rate cuts slowly, blunting policy — a reason for the external benchmark lending-rate rules introduced in 2019.
