Macroeconomics: Fiscal and Monetary Policy Explained
Part 1: Fiscal Policy
Fundamentals of Fiscal Policy
Fiscal policy is the mechanism by which a government manages its receipts (revenue) and expenditure to influence the economy. Increasing spending stimulates growth, while reducing it helps curb inflation.
- Revenue Receipts: Regular income, such as taxes (Income Tax, GST) and non-tax revenue (fees, PSU dividends).
- Capital Receipts: One-time or debt-based inflows, including borrowings, asset sales, and disinvestment.
Note: GST replaced VAT and excise in July 2017 but excludes petroleum, alcohol, and electricity.
Understanding the Three Deficits
- Revenue Deficit: Revenue Expenditure minus Revenue Receipts. Indicates if the government is borrowing to fund daily expenses.
- Fiscal Deficit: Total Expenditure minus (Revenue Receipts + Non-debt Capital Receipts). The total shortfall bridged by borrowing.
- Primary Deficit: Fiscal Deficit minus Interest Payments. Reflects the current fiscal burden by excluding past debt obligations.
The FRBM Act (2003)
The Fiscal Responsibility and Budget Management (FRBM) Act serves as a fiscal constitution to ensure discipline. It tracks the Fiscal Health Index (FHI) across five dimensions: quality of expenditure, revenue mobilization, fiscal prudence, debt index, and debt sustainability.
Part 2: The 2008 Credit Crisis
The Core Story
The crisis originated from a global savings glut that kept US interest rates low, fueling a housing bubble. Banks utilized securitization to bundle loans into Mortgage-Backed Securities (MBS), adopting an originate-to-distribute model that removed the incentive to ensure loan quality.
Instruments of Risk
- CDO (Collateralized Debt Obligation): Bundled MBS sliced into tranches; risk was hidden, not eliminated.
- CDS (Credit Default Swap): Insurance against default that became a massive, unregulated market.
- SIV (Structured Investment Vehicle): Off-balance-sheet entities used to hide short-term liabilities against long-term assets.
Collapse Sequence
As interest rates rose, defaults spiked, house prices fell, and institutions like Lehman Brothers (bankrupt Sept 2008) collapsed. The crisis was exacerbated by thin capital buffers, often as low as 2%.
Part 3: Monetary Policy
RBI and Money Supply
Monetary policy manages money supply and interest rates to stabilize the economy. Key metrics include:
- M0 (Reserve Money): Currency in circulation plus deposits with the RBI.
- M3 (Broad Money): M1 plus time deposits; the most closely monitored figure.
- Money Multiplier: M3 divided by M0, representing how banking amplifies the base money.
RBI Policy Tools
- CRR (Cash Reserve Ratio): Percentage of NDTL parked with RBI at zero interest.
- SLR (Statutory Liquidity Ratio): Percentage of NDTL held in liquid assets (gold, G-secs).
- Repo Rate: The policy rate at which RBI lends to banks.
- OMO (Open Market Operations): Buying or selling G-secs to manage liquidity.
- LAF Corridor: SDF (floor), Repo Rate (anchor), and MSF (ceiling).
The Impossible Trinity
A country cannot simultaneously maintain a fixed exchange rate, free capital flows, and an independent monetary policy. Nations must choose two of these three pillars.
