The South Korean won averaged 1,489.3 per dollar through the first 27 days of March. This currency pressure pushed the monthly average to the fourth-lowest on record. The won-dollar rate breached 1,500 on a weekly basis for the first time in 17 years. Consequently, the won has become the worst-performing major currency this month.
The won fell 4.72 percent against the US dollar in the first 28 days of March. This marks the steepest monthly decline among major currencies. The US Dollar Index rose 2.6 percent over the same period. The euro fell 2.62 percent, the yen dropped 2.58 percent, and the yuan declined 0.84 percent. The won’s sharp drop outpaced all its peers. Therefore, this currency pressure reflects unique vulnerabilities in the Korean economy.
Foreign investors sold a net 29.8 trillion won worth of Korean stocks in March. This massive selloff followed a net 21.1 trillion won exodus in February. Prolonged Middle East tensions and concerns over artificial intelligence technology drove the selling. The war has effectively closed the Strait of Hormuz, a critical energy chokepoint. Korea depends heavily on oil imports through this waterway. Consequently, the currency pressure stems from both geopolitical and sector-specific factors.
The won’s monthly average of 1,489.3 ranks as the fourth-lowest in history. Only three months during the 1997 Asian financial crisis recorded weaker averages. Those were December 1997 at 1,499.38, January 1998 at 1,701.53, and December 1998 at 1,626.75. The current currency pressure has not yet reached crisis-era levels. However, the trend line points toward continued weakness.
On a weekly basis, the average won-dollar rate reached 1,503.4 last week. This breached the 1,500 threshold for the first time since March 2009. The won last traded consistently above 1,500 during the global financial crisis. That period also saw massive capital outflows and risk aversion. Therefore, this currency pressure echoes past episodes of market stress.
Analysts expect the won to hover around 1,500 even after the Middle East conflict subsides. Shinhan Bank economist Baek Seok-hyun said damaged energy facilities in Gulf states will take years to normalize. The Strait of Hormuz is also likely to remain disrupted for an extended period. “The exchange rate is highly likely to remain in the 1,500 won range,” Baek said. Consequently, this currency pressure may persist well beyond the current crisis.
The won’s decline has exceeded that of other major currencies by a wide margin. Foreign investor selling has focused heavily on Korean equities. The AI sector outlook has weakened, hitting Korean semiconductor stocks particularly hard. Samsung Electronics and SK hynix have seen significant outflows. Therefore, this currency pressure connects to sector-specific challenges alongside broader geopolitical risks.
The Bank of Korea has monitored the situation closely. The central bank may consider intervention if volatility intensifies further. However, intervention would only slow the decline, not reverse it. The fundamental drivers of currency pressure remain in place. Consequently, policymakers face difficult choices between defending the won and preserving reserves.
Importers are feeling the pinch from the weaker won. Energy costs have risen sharply as the currency has fallen. Consumer prices may face upward pressure in coming months. The government has already introduced fuel price caps and a supplementary budget. Therefore, this currency pressure has direct implications for household living costs.
The won’s weakness also affects Korean companies with foreign currency debt. Their repayment burdens have increased as the exchange rate has deteriorated. Some firms may face refinancing challenges if the won remains weak. The corporate sector will need to manage currency risk carefully. Consequently, this currency pressure extends beyond financial markets into the real economy.
Exporters present a mixed picture from the weaker won. Those with foreign currency revenues benefit from the exchange rate. However, imported materials have become more expensive, squeezing margins. The net effect varies by industry and company. Therefore, this currency pressure produces winners and losers across the economy.
The South Korean won has faced intense currency pressure in March, breaching the 1,500 level for the first time in 17 years. The won fell 4.72 percent against the dollar, the steepest decline among major currencies. Foreign investors sold nearly 30 trillion won in Korean stocks amid Middle East tensions and AI concerns. Analysts expect the won to remain around 1,500 even after the conflict subsides. This currency pressure echoes past crisis periods and has broad implications for importers, consumers, and the broader economy. Policymakers face difficult trade-offs as they navigate the current turbulence.
