What a current account deficit is and how to measure it

A current account deficit occurs in a country's balance of payments when the money leaving the economy exceeds the money entering it through certain channels. This happens if the combined value of net exports (exports minus imports) of goods and services, plus net income from investments abroad, plus net transfers (such as aid or remittances), results in a negative figure.

Key features of a current account deficit

• Currency flow imbalance - More currency flows out of the country than comes in, which can put downward pressure on the value of the national currency.
• Measurement as a percentage of GDP - The size of the deficit should be assessed relative to the country's gross domestic product (GDP) rather than in absolute numbers, as this gives a better sense of its economic significance.
• Narrowing deficits - A reduction in the deficit is not always a good sign, as it might result from an overall economic slowdown rather than improved trade performance.
• Growing deficits - An increasing deficit is not necessarily a problem if it stems from investments in productive assets, such as machinery, that could boost future exports in a developing economy.

When current account deficits are and are not concerning

Not all current account deficits pose a threat to an economy; some are temporary and self-correcting, while others signal deeper issues that require attention.

Situations when deficits are generally not concerning

• Cyclical deficits - These rise during periods of strong economic growth (booms) when imports increase, and fall during slowdowns as demand for imports drops.
• Transitory deficits - Short-term imbalances caused by one-off events, such as weather-related disruptions to agricultural exports.
• Deficits expected to reverse - Those that are likely to correct themselves naturally over time without intervention.

Situations when deficits are concerning

• Large relative size - When the deficit forms a substantial share of GDP, indicating a heavy reliance on foreign funding.
• Persistent nature - Long-lasting deficits that continue over many years without improvement.
• Structural economic issues - Deficits linked to underlying problems like ongoing high inflation, lack of competitiveness in global markets, or inflexible labour markets that hinder adaptation.

How persistent current account deficits are financed

Ongoing current account deficits cannot continue indefinitely without some form of funding to balance the outflows. Countries must attract money from abroad to cover the gap.

Methods of financing deficits

• Private capital inflows - Attracting investments from foreign businesses or individuals, such as through stock markets or direct investments in companies.
• Official borrowing - Governments taking loans from international organisations or other countries to bridge the shortfall.

If financing dries up, the deficit can lead to economic instability, forcing adjustments in trade or currency values.

The economic effects of current account deficits

Current account deficits, especially persistent ones, can have wide-ranging impacts on various aspects of the economy, from currency values to long-term growth prospects.

Effects on exchange rates

• Downward pressure on currency - Deficits increase the supply of the national currency abroad, often leading to depreciation.
• Risk of sudden falls - If foreign investors lose faith in the economy, the currency may depreciate sharply.
• Inflationary pressures - A weaker currency raises the cost of imports, potentially causing cost-push inflation.
• Impact on households - Lower-income families are hit hardest by higher prices for imported essentials like food and fuel.

Effects on interest rates

• Rate increases by central banks - To draw in foreign capital, interest rates may be raised, making borrowing more expensive.
• Government budget strain - Higher rates mean more public money goes towards interest payments on debt.
• Reduced economic activity - Costlier borrowing discourages consumer spending and business investment, lowering aggregate demand and increasing recession risks.

Implications for foreign ownership

• Sale of domestic assets - Countries may need to sell assets like land or companies to foreign buyers to raise funds.
• Discounted sales in weak economies - Poor economic conditions can force assets to be sold at lower prices.
• Loss of key assets - Strategic resources, such as natural reserves, banks, or transport networks, might come under foreign control.
• Threat to sovereignty - Increased foreign ownership can limit a country's control over its own economic decisions.

Consequences for national debt

• Diversion of future income - Repayments on accumulated debt reduce funds available for other uses.
• Export earnings redirected - Money from exports is used to service debt instead of buying imports.
• Limited public investment - Less money for essential areas like roads, hospitals, and schools.
• Higher borrowing costs - Lenders demand higher interest rates due to increased risk.
• Credit rating downgrades - Agencies such as Fitch, Moody's, and Standard & Poor's may lower ratings, making borrowing even more expensive.
• Risk of default - In extreme cases, countries may fail to repay debts, leading to forced economic reforms.

Implications for demand management

• Need for contractionary measures - Policies to reduce spending, such as cutting government budgets, may be required to curb imports.
• Lower incomes and imports - Reduced economic activity decreases demand for foreign goods.
• Rising unemployment - Job losses occur as demand falls.

Long-term growth impacts

• Prolonged recovery periods - Overcoming the effects of a deficit crisis can take several years.
• Diminished investment capacity - Governments have less ability to fund growth-promoting projects.
• Eroded investor confidence - It takes time to rebuild trust from foreign investors.
• Worsening inequality - Deficits often increase the gap between rich and poor.
• Risks of overconsumption - Living beyond means through deficits can lead to severe long-term economic damage.
