Finance minister calls for efforts to address global imbalances at G20 meeting

Global imbalances occur when some economies run large current-account surpluses while others run deficits. Lee said these differences require coordinated action because policies in one country can affect trade, capital flows and financial stability elsewhere.

At the G7 finance ministers’ meeting, Lee called for comprehensive macroeconomic policies and structural reforms. He also stressed cooperation within the G7 and with the broader G20. The proposed approach was not limited to reducing exports or imports. It included addressing underlying economic structures that influence saving, spending, investment and competitiveness.

The call came during wider discussions about debt and financial stability. Lee also urged joint action on supply-chain disruptions linked to the Middle East war and on finding growth engines as AI develops. South Korea said it would contribute to global economic stability and growth, while continuing cooperation with partners such as Australia, which co-chaired a G20 study group on imbalances.

A current account records a country’s trade in goods and services, plus certain income and transfers. A surplus means the country receives more from the rest of the world than it pays. A deficit means it pays more than it receives. The article defines global imbalances as large surpluses in some countries leading to deficits in others.

The link works through trade and finance. A surplus country may export more than it imports and lend its extra savings abroad. A deficit country may import more than it exports and attract foreign money to finance that gap. One country’s net exports therefore correspond broadly to another’s net borrowing.

This relationship is not automatically harmful. Imbalances can reflect productive investment or different stages of development. They become a concern when they persist, depend on heavy borrowing, or create vulnerability to sudden changes in exchange rates, interest rates or investor confidence. That is why G20 and G7 officials discuss them alongside debt and financial stability.

Global imbalances are large by any practical measure. In recent years, the combined absolute value of major economies’ current-account balances has been several trillion U.S. dollars annually. The exact total changes with commodity prices, exchange rates, domestic demand and global growth. International institutions therefore assess both the size and persistence of each country’s balance.

China, Germany, Japan and some oil-exporting economies have often been among the biggest surplus economies. The United States has typically recorded the world’s largest current-account deficit. The United Kingdom and India have also frequently run deficits, although rankings and amounts vary. A surplus or deficit can change as energy prices, imports, exports or investment shift.

These patterns matter because they connect economies through trade and finance. Surplus countries accumulate foreign assets or lend abroad, while deficit countries attract financing. The article does not provide current figures or rankings, so the scale described here uses established international economic patterns rather than numbers from the report. Lee’s meetings focused on coordinated responses.

A persistent trade surplus can make growth overly dependent on exports and foreign demand. A persistent deficit can increase reliance on foreign borrowing. Neither outcome is automatically damaging, but long-running gaps can become risky when debt rises, investment is poor or economies cannot adjust smoothly. The article links imbalances with debt and financial stability for this reason.

For households, adjustment may mean weaker wages or employment in exposed industries, higher borrowing costs, or pressure to reduce spending. Surplus-country households may also face limited domestic consumption if policy favors saving and exports. Deficit-country households can benefit from plentiful imported goods, but later face tighter credit or falling incomes if financing becomes harder to obtain.

Financial markets can react when investors question a country’s ability to repay or attract capital. Currency declines may raise import prices and foreign-currency debt burdens. Asset prices and interest rates can move sharply. These effects explain why Lee advocated comprehensive policies and structural reforms, rather than relying on trade restrictions alone.

Supply chains connect factories, consumers and countries. Disruptions linked to the Middle East war can delay inputs, raise costs and weaken production across borders. High debt adds pressure because governments, companies and households have less room to absorb higher interest rates or new shocks. These problems cannot be managed fully by one country alone.

AI creates both opportunity and adjustment costs. It may raise productivity and open new industries, but investment, skills and rules must develop quickly. Lee urged members to identify new growth engines and invest proactively in future sectors. He also highlighted the need to strengthen supply-chain resilience and protect vulnerable groups.

Cooperation helps governments share information, keep trade routes and finance functioning, and coordinate responses. The G20 discussed imbalances, debt and financial stability together. Lee’s meetings with Germany, Australia, Singapore, the ADB and others show the practical side of that cooperation: building projects, exchanging expertise and preparing joint approaches to future economic pressures.

Countries can narrow imbalances through policies that address their domestic causes. Surplus economies might strengthen household incomes, social protection and public investment, encouraging more consumption and imports. Deficit economies can improve competitiveness, raise domestic saving, and direct borrowing toward productive investment rather than consumption. Fiscal and financial policies should remain sustainable.

Structural reforms can improve productivity, workforce skills, competition and infrastructure. Exchange-rate flexibility may help prices adjust, although currency changes alone cannot solve every imbalance. Countries can also reduce excessive subsidies, remove barriers that distort investment, and cooperate on standards and supply chains. These steps aim to change economic incentives without abruptly shutting trade.

The transition must be gradual and protect vulnerable groups. Sudden austerity or broad trade barriers can reduce demand, disrupt supply chains and weaken growth. Lee called for comprehensive macroeconomic policies and structural reforms, plus cooperation among G7 and G20 members. That approach matches the need to correct imbalances while preserving investment, trade and future growth.

Exports add to the current account, while imports subtract from it. Income received from foreign assets can add to the balance, while payments to foreign owners can reduce it. At the national level, the current account broadly equals saving minus domestic investment. A country that saves more than it invests has funds to lend abroad and usually runs a surplus.

For example, strong household or government saving can finance factories at home and purchases of foreign assets. If domestic investment remains smaller than total saving, exports or foreign lending fill the gap. Conversely, a country investing heavily or consuming more than it saves may import capital and goods, producing a deficit. Capital flows therefore mirror the financial side of trade.

Exchange rates influence these relationships by changing the prices of exports and imports. A weaker currency can support exports and make imports costlier, though adjustment takes time. The article’s definition captures the outcome: some countries’ large surpluses correspond to others’ deficits. G20 discussions seek cooperation because these positions are interconnected.
