Current Account Deficit and Surplus Quiz: Causes and Effects

A current account surplus means a country's total receipts from trade in goods and services, primary income, and secondary income transfers exceed its total payments to the rest of the world. This makes the country a net lender to the global economy, accumulating foreign financial claims. Countries like Germany and China have maintained persistent surpluses by generating more in export and investment income than they spend on imports and transfers.

The answer is True. Because the Balance of Payments must theoretically sum to zero, a current account deficit must be offset by an equivalent surplus elsewhere, either in the financial account through foreign borrowing or investment inflows, or by drawing down official reserve assets. This relationship reflects the fundamental accounting identity of the BoP and explains how countries sustain deficits over time.

A current account deficit is not always negative. When driven by inflows of productive foreign investment rather than excessive consumer borrowing, it can signal that foreign investors see strong growth prospects in the country. The United States has sustained long-running deficits partly because global investors actively choose to place capital in its economy, funding business expansion and job creation.

All four factors can contribute to a worsening current account deficit. Higher import spending increases debit entries. Export competitiveness decline reduces credit entries. A strong currency makes imports cheaper and exports more expensive, worsening the trade balance. Large outflows of investment income to foreign investors increase primary income debits. Together these pressures reduce overall current account receipts relative to payments.

The answer is False. While a current account deficit can be sustained for extended periods, it cannot continue indefinitely without consequences. Persistent deficits require ongoing foreign financing through borrowing or asset sales. Over time, rising foreign debt levels increase interest payments, weaken the currency, and may eventually trigger a loss of investor confidence or a balance of payments crisis if deficits become too large or unsustainable.

A country that consistently runs a current account surplus accumulates financial claims on the rest of the world, becoming a net international creditor. Its residents and institutions invest the surplus income in foreign assets, including bonds, stocks, and direct investments. Over time, this builds a large stock of foreign assets, strengthening the country's international investment position and generating growing primary income flows back home.

The current account balance equals the gap between national savings and domestic investment. When a country invests more than it saves, it must borrow the difference from abroad, which results in a current account deficit. Conversely, when savings exceed investment, the surplus funds flow abroad, creating a current account surplus. This savings-investment identity is a fundamental framework for understanding persistent current account imbalances.

The answer is False. Large and persistent current account surpluses are often a source of international trade tension. Trading partners may argue that surplus countries are keeping their currencies undervalued, suppressing wages, or using unfair industrial policies to boost exports at the expense of other nations. The United States and European Union have raised concerns about surplus countries such as China and Germany, leading to broader debates about global imbalances.

Persistent current account deficits can lead to accumulating foreign debt, currency depreciation pressure as demand for foreign currency rises with imports, and vulnerability to capital flow reversals if foreign investors suddenly reduce their exposure. They do not guarantee economic growth improvement. In fact, if deficits reflect excessive consumption rather than productive investment, they can contribute to long-term economic fragility.

The twin deficits hypothesis argues that when a government runs a budget deficit by spending more than it collects in taxes, it reduces national savings. With less domestic saving available to fund investment, the country must attract foreign capital, which tends to generate a current account deficit. The United States in the 1980s is a widely cited example where rising fiscal deficits coincided with a growing current account deficit.

The answer is True. At the global level, all current account positions must sum to zero because every export from one country is an import for another, and every income payment out is income received elsewhere. This means that if some countries run surpluses, other countries must collectively run offsetting deficits. Persistent global imbalances, where surpluses and deficits are large and concentrated, are a major concern in international economics.

To reduce a current account deficit, a government can address the underlying savings-investment gap. Encouraging higher domestic savings and reducing the fiscal deficit lowers the need for foreign borrowing. A stronger savings position reduces the gap that must be filled by foreign capital, gradually improving the current account balance. Structural measures that boost export competitiveness are also effective in addressing persistent deficits.

When foreign investors suddenly withdraw capital from a country running a large current account deficit, the loss of financing can cause a sharp currency depreciation and force a rapid adjustment. Imports become more expensive, reducing demand, while exports become more competitive. This painful adjustment, known as a sudden stop, can cause economic contraction and financial instability, as seen in several emerging market crises historically.

A current account surplus means total international receipts exceed total payments across all sub-accounts including goods, services, primary income, and secondary income. This surplus must be matched by an equivalent outflow in the financial account or an increase in reserve assets. However, a country can still carry significant foreign debt from prior borrowing even while running a current account surplus, so having a surplus does not eliminate foreign debt obligations.

The answer is False. The current account encompasses four distinct components: trade in goods, trade in services, primary income including dividends and wages, and secondary income including remittances and foreign aid. Each of these components contributes to the overall current account balance. Focusing only on goods trade provides an incomplete picture, and countries can have very different current account outcomes depending on the size of their income and transfer flows.
