Questions: Capital Flows and the Financial Account

Question 1

A country runs a $200 billion current account deficit in a given year. Which of the following must also be true by accounting identity?

• A. The country's foreign exchange reserves fall by exactly $200 billion
• B. Foreigners accumulate $200 billion more claims on the country than the country accumulates on foreigners — a financial account surplus of $200 billion
• C. The country borrows $200 billion from the IMF or other multilateral lenders
• D. The country's trade in goods and services is negative by exactly $200 billion

Answer: (B)

The balance of payments accounting identity requires that current account + financial account = 0. A current account deficit of $200 billion must be exactly matched by a financial account surplus of $200 billion. This is not an economic relationship — it is a definitional identity, because every international transaction that sends goods or services out also brings a financial claim back. Options A, C, and D are specific channels through which the surplus could occur but are not necessarily true.

Question 2

East Asian economies in the 1990s attracted large capital inflows that ultimately contributed to the 1997–98 financial crisis. Which feature of these inflows best explains their role in the crisis?

• A. The inflows were concentrated in foreign direct investment, which cannot be withdrawn quickly, so the problem was illiquidity rather than capital flight
• B. The inflows were dominated by portfolio investment and short-term debt, which could be reversed almost overnight when investor confidence collapsed, triggering a sudden stop and currency crisis
• C. Central banks in these countries prevented exchange rate adjustment, so capital inflows accumulated as reserves rather than financing investment
• D. The inflows caused large trade surpluses that eventually became unsustainable and triggered a correction

Answer: (B)

The crucial factor was the composition of inflows. Portfolio investments — stocks, bonds, short-term bank loans — are liquid and sentiment-driven. When investors simultaneously lost confidence in growth prospects and exchange rate sustainability, they sold en masse. This sudden reversal (the 'sudden stop') drained financing for current account deficits, forced sharp currency depreciation, and triggered recessions. FDI, by contrast, cannot be withdrawn with a keystroke — a factory does not leave during a panic.

Question 3

A country's current account deficit is necessarily matched by a financial account surplus of equal magnitude, because every international transaction involves both a real-side exchange and a financial-side payment.

• T. True
• F. False

Answer: True

This is an accounting identity, not an economic law. When a country imports more than it exports, the difference must be financed — foreigners receive payment and hold the resulting claims as financial assets. The balance of payments records these two sides of every transaction: the real exchange (goods, services) in the current account and the corresponding financial claim in the financial account. They sum to zero by construction, not coincidence.

Question 4

Foreign direct investment poses the same sudden stop risk as portfolio investment, because both represent foreign ownership of domestic assets and can be withdrawn if investor sentiment shifts.

• T. True
• F. False

Answer: False

FDI and portfolio investment are very different in practice. FDI involves acquiring physical production capacity — factories, subsidiaries, lasting business relationships. These cannot be liquidated quickly during a panic. Portfolio investment (equities, bonds, money market instruments) can be sold globally within seconds. During the EM crises of the 1990s, it was portfolio flows and short-term bank lending — not FDI — that reversed suddenly and caused financial distress. Countries with FDI-heavy capital inflows were far more resilient.

Question 5

What is a 'sudden stop' in capital flows, and why does the composition of a country's capital inflows determine how severe its economic consequences will be?

Model answer: A sudden stop is an abrupt reversal of capital inflows — foreign investors simultaneously sell domestic assets and withdraw financing. Its severity depends on the composition of prior inflows. If inflows were concentrated in short-term debt or portfolio investment, investors can exit rapidly, triggering a sharp fall in the financial account surplus. This forces either a large currency depreciation (to reduce the current account deficit) or a drain of foreign exchange reserves. Countries financed primarily by FDI are more insulated because FDI cannot be quickly liquidated, providing a buffer against mass exit.

The composition insight is subtle. Two countries with identical current account deficits face very different risks depending on how those deficits are financed. A deficit financed by FDI is stable; one financed by hot money (short-term portfolio flows) is fragile. This is why analysts track not just the size of deficits but their financing mix, and why the IMF often advises countries to attract FDI rather than relying on portfolio debt inflows.
