6.1.3 Balance of Payments Surplus and Deficit
The Balance of Payments (BoP) must always balance because any deficit or surplus in the current account must be offset by corresponding movements in the capital account or official reserves.
If a country has a current account deficit, it means it is spending more on foreign goods and services than it earns from exports. To finance this deficit, the country must borrow from abroad or sell assets, resulting in a capital account surplus (net capital inflow).
The fundamental identity is: Current account + Capital account = 0
When this identity holds without any change in official reserves, the BoP is said to be in equilibrium.
Alternatively, a country can use its official reserves (foreign exchange reserves) to finance a BoP deficit. The central bank sells foreign exchange reserves to meet the excess demand for foreign currency. A decrease in reserves indicates a BoP deficit, while an increase indicates a surplus.
Official reserve transactions are more significant under fixed exchange rate regimes, where the central bank actively intervenes to maintain the exchange rate.
Autonomous transactions are those made for reasons other than balancing the BoP, such as profit-seeking investments. Accommodating transactions respond to BoP imbalances and include official reserve adjustments.
Errors and omissions arise because it is difficult to record all international transactions accurately. They ensure that the BoP accounts balance mathematically.
Table 6.1 shows India's BoP with a trade deficit and current account deficit but a capital account surplus, resulting in an overall balance of zero.

🔗 Connection: This section prepares the understanding of how exchange rates are determined in the foreign exchange market, which is crucial for managing BoP.

Frequently asked questions
Differentiate between balance of trade and current account balance.
Balance of trade refers to the difference between the value of exports and imports of goods only, whereas the current account balance includes the balance of trade plus net income from abroad (such as remittances, interest, dividends) and net current transfers. Thus, the current account balance is a broader measure of a country's international transactions in goods, services, income, and current transfers.
What are official reserve transactions? Explain their importance in the balance of payments.
Official reserve transactions refer to the buying and selling of foreign exchange reserves by a country's central bank or monetary authority to influence the exchange rate or to maintain the balance of payments equilibrium. These reserves typically include foreign currencies, gold, and special drawing rights (SDRs). Their importance lies in stabilizing the currency, financing deficits in the balance of payments, and maintaining confidence in the country's external financial position.
Distinguish between the nominal exchange rate and the real exchange rate. If you were to decide whether to buy domestic goods or foreign goods, which rate would be more relevant? Explain.
The nominal exchange rate is the rate at which one currency can be exchanged for another currency. It is expressed as the price of one currency in terms of another (e.g., 1 USD = 75 INR).
The real exchange rate adjusts the nominal exchange rate for differences in price levels between countries. It measures the relative price of domestic goods in terms of foreign goods and is calculated as:
Real Exchange Rate (R) = (Nominal Exchange Rate × Domestic Price Level) / Foreign Price Level
The real e
Suppose it takes 1.25 yen to buy a rupee, and the price level in Japan is 3 and the price level in India is 1.2. Calculate the real exchange rate between India and Japan (the price of Japanese goods in terms of Indian goods). (Hint: First find out the nominal exchange rate as a price of yen in rupees).
Given: 1.25 yen = 1 rupee Price level in Japan (P*) = 3 Price level in India (P) = 1.2
Step 1: Find nominal exchange rate as price of yen in rupees: Since 1 rupee = 1.25 yen, 1 yen = 1 / 1.25 = 0.8 rupees
Step 2: Calculate real exchange rate (R): R = (Nominal exchange rate × Domestic price level) / Foreign price level Here, domestic country is India, foreign is Japan.
R = (0.8 × 1.2) / 3 = 0.96 / 3 = 0.32
Interpretation: The real exchange rate is 0.32, meaning Japanese goods cost 0.32 times
