Questions: The Current Account and External Balance

Question 1

A developing country is running a large current account deficit while GDP grows rapidly. The deficit is driven by massive imports of industrial machinery and capital equipment. An economist argues this deficit is not necessarily problematic. What is the best reason for this view?

• A. Current account deficits are always harmless for developing countries regardless of what drives them
• B. The imports are building productive capacity, so the borrowed resources are being deployed to generate future income that can service the debt
• C. The deficit will automatically close once the country's currency depreciates to restore competitiveness
• D. Developing countries are exempt from the sustainability concerns that apply to advanced economies

Answer: (B)

Whether a deficit is problematic depends entirely on what drives it. A deficit fueled by investment in productive capacity — importing capital equipment to build factories, infrastructure, or technology — is fundamentally different from one driven by consumption beyond income. In the investment-driven case, the borrowed resources create the future income needed to service the debt. In the consumption case, external debt accumulates without a corresponding increase in productive capacity.

Question 2

A politician warns: 'Our current account deficit is a crisis — we are spending more than we earn and going into debt.' A more complete macroeconomic analysis would add which of the following?

• A. The politician is right; every current account deficit represents a financial emergency requiring immediate policy action
• B. Whether the deficit is sustainable depends on what drives it, and the deficit is always exactly offset by a financial account surplus — foreign capital inflows finance the gap
• C. Current account deficits are always offset by trade surpluses in subsequent periods through automatic adjustment
• D. The financial account has no systematic relationship to the current account balance

Answer: (B)

Two things the politician misses: First, the deficit's significance depends on its cause — high investment can justify deficits, low saving is more concerning. Second, the balance of payments identity means every current account deficit is exactly matched by a financial account surplus — foreigners are sending capital in (buying bonds, making investments) to finance the gap. The 'going into debt' framing is partially right but ignores that foreigners willingly provide that financing, often because returns in the country are attractive.

Question 3

A country running a current account deficit must simultaneously be receiving net financial inflows from abroad, because the financial account and current account must sum to zero in the balance of payments.

• T. True
• F. False

Answer: True

This is an accounting identity, not an empirical generalization. Every current account deficit means domestic spending exceeds domestic income; the difference must be financed by net claims from foreigners, which shows up as a financial account surplus of equal magnitude. Foreigners are acquiring domestic assets (bonds, equity, real estate, direct investments) in exchange for the goods and services the country is importing in excess of its exports.

Question 4

A large, persistent current account deficit is generally a sign of an economy in trouble and requires immediate policy correction.

• T. True
• F. False

Answer: False

The United States has run large current account deficits for decades; whether this represents a crisis or a sustainable arrangement is genuinely debated. Defenders argue the deficit reflects the dollar's reserve currency status and strong U.S. investment returns; critics argue it reflects structural competitiveness problems and unsustainable consumption. Deficits become genuinely problematic when they require ever-larger borrowing just to service existing external debt — a dynamic that can trigger currency crises — but not every deficit reaches that point.

Question 5

Why does a current account deficit not automatically indicate economic mismanagement, even though it means a country is spending more than it earns?

Model answer: Because the deficit's significance depends on what drives it. A deficit caused by high investment demand — a country borrowing to build productive capacity — can be entirely appropriate: the borrowed resources generate future income to service the debt. A deficit caused by low saving (consuming beyond income) is more concerning because it accumulates external claims without building productive capacity. The same deficit size can be benign or dangerous depending on its underlying cause.

The key insight is separating the accounting fact (spending > income, matched by capital inflows) from the economic judgment (is this sustainable and beneficial?). Conflating them leads to either panic about every deficit or complacency about genuinely dangerous ones. The diagnostic questions are: what is the money being used for, and is the economy building the capacity to service its growing external obligations?
