Open Economy Macroeconomics
Anchors India's external sector dynamics, balancing BoP accounting rules, foreign exchange determination, capital account convertibility, and official reserve transactions.
6.1 The Balance of Payments
This section is extremely high yield. UPSC frequently tests the classification of transactions under the Current Account (trade in goods, services, unilateral transfer payments) and the Capital Account (FDI, FPI, external commercial borrowings, external assistance). Focus heavily on the accounting balance vs economic balance: BoP as an accounting identity always balances, but the autonomous transactions can create a surplus or deficit which is settled by accommodating transactions (official reserves). Watch out for traps: unilateral transfers are part of the Current Account, not the Capital Account, and FDI involves a lasting interest/management control (>10% equity) unlike portfolio investment.
6.2 The Foreign Exchange Market
Crucial for understanding how currency values fluctuate. Focus on the concepts of Nominal Effective Exchange Rate (NEER) and Real Effective Exchange Rate (REER), where REER adjusts NEER for inflation differentials, serving as a key indicator of trade competitiveness. Understand the mechanics of currency depreciation vs devaluation (market-driven vs policy-driven), and fixed vs flexible vs managed floating exchange rate systems. UPSC often tests how domestic inflation or interest rate hikes by foreign central banks (like the US Fed) trigger capital flight and put depreciation pressure on the Rupee.
