The longstanding principle that a surge in exports stabilizes exchange rates is no longer valid. Historically, an increase in South Korea's exports signaled an influx of foreign currency, typically leading to a stronger won and stable exchange rates. However, the current foreign exchange market operates differently. Despite improved export performance, particularly in semiconductors, the won-dollar exchange rate remains elevated and shows little sign of decline. Relying solely on export growth to ensure exchange rate stability is inadequate in today's market.
The most significant change is the altered flow of capital. In the past, trade balance was the primary factor influencing exchange rates. Now, capital movement has become equally, if not more, influential. Domestic investors are pouring substantial amounts into U.S. stocks and overseas exchange-traded funds. Pension funds and institutional investors are also increasing their allocations to foreign assets. Many companies are opting to reinvest their dollar earnings abroad rather than bringing them back to South Korea. This means that even when dollars are earned through exports, there is no guarantee they will be immediately supplied to the domestic foreign exchange market.
The interest rate differential between the U.S. and South Korea is another factor contributing to exchange rate instability. The prolonged high interest rates in the U.S. continue to enhance the appeal of dollar-denominated assets. Even as South Korea earns foreign currency through exports, global capital tends to flow toward dollar assets in search of higher returns and safety. Coupled with geopolitical risks and uncertainties surrounding U.S. fiscal and trade policies, non-reserve currencies like the won are under significant depreciation pressure. Exchange rates are now determined not just by trade balances but also by global capital flows, investor sentiment, and interest rate differentials.
The government's response must also evolve. Relying on verbal interventions or using foreign reserves to suppress the market has its limits. While stabilization measures are necessary during periods of extreme volatility, if high exchange rates stem from structural changes, short-term fixes will not be effective. The market may perceive that the government is stuck in outdated approaches.
A new framework for foreign exchange policy is essential. First, incentives should be strengthened to ensure that dollars earned by exporting companies are smoothly supplied to the domestic market. If increased overseas investment is unavoidable, it is crucial to establish institutional mechanisms that can stabilize the foreign exchange market while accommodating this trend. Large institutional investors, such as the National Pension Service, should refine their overseas investment and currency hedging strategies to mitigate market shocks. Additionally, the rise in individual overseas investments should be recognized as a new variable, necessitating enhanced statistics and monitoring systems.
Above all, exchange rate stability should be viewed as a matter of restoring trust in the overall macroeconomy. Without sound fiscal health, industrial competitiveness, financial market stability, and consistent monetary policy, confidence in the won is easily undermined. Expecting exchange rates to stabilize simply because exports are performing well is a dangerous misconception. The phenomenon of a weakening won despite strong export performance signals that South Korea's foreign exchange policy has entered a new phase.
The paradox of rising exchange rates amid a booming export market is not a temporary anomaly; it is a result of changes in the flow of money and investment structures within the South Korean economy. The government must not rely on past success formulas but instead develop foreign exchange policies suited to an era of free capital movement. High exchange rates should not be dismissed as a mere temporary market disturbance but should be interpreted as a signal to reassess the economic fundamentals of South Korea.
