D) Balance of payments equilibrium on current account

The idea

Achieving a balance of payments equilibrium on the current account is a key macroeconomic objective. The current account measures flows of goods, services, primary income, and secondary income between a country and the rest of the world. Equilibrium means inflows roughly match outflows over time, avoiding large, persistent deficits or surpluses. A persistent deficit can indicate a lack of international competitiveness and may require financing through borrowing, increasing external debt. Conversely, a large surplus might suggest an over-reliance on exports and suppressed domestic consumption.

For example: A country running a persistent trade deficit may face downward pressure on its exchange rate and long-term structural economic weaknesses.

What earns the marks

• Define the current account of the balance of payments as the record of trade in goods and services, plus primary and secondary income flows.
• Explain that equilibrium means the current account is broadly in balance, without unsustainable deficits or surpluses.
• Identify that a persistent current account deficit may indicate structural weaknesses, such as poor productivity or high relative inflation.
• Recognise that financing a large deficit requires inflows on the financial account, which can increase a nation's external debt.
• Explain that while a surplus is often viewed positively, a very large surplus can cause political friction and indicate unbalanced domestic consumption.

Common mistakes and how to put them right

• Confusing the government budget deficit with the current account deficit.

  Put it right: The budget deficit relates to government spending exceeding tax revenue, whereas the current account deficit relates to international trade and income flows.

• Assuming a current account deficit is always bad.

  Put it right: A deficit can be acceptable if it is driven by imports of capital goods that will increase future productive capacity and economic growth.

• Forgetting the income components of the current account.

  Put it right: The current account includes primary income (investment income) and secondary income (transfers), not just the trade in goods and services.

Exam tips

• When evaluating the significance of a current account deficit, consider its size as a percentage of GDP rather than just the absolute monetary value.
• Discuss the causes of a deficit, such as high domestic growth sucking in imports versus structural uncompetitiveness, to provide a nuanced evaluation.
• Link the current account position to other macroeconomic objectives, such as economic growth and employment, to demonstrate synoptic understanding.
