Current Status

The USD/KRW exchange rate closed at 1491.6957 on March 13, 2026, marking a significant daily gain of +0.733%. This movement signifies a depreciation of the South Korean Won (KRW) against the US Dollar (USD), meaning it takes more Won to purchase one Dollar. The primary driver for this move was overwhelmingly the USD, attributed 84% of the influence, compared to only 16% from the KRW side. This suggests broad-based USD strength or a localized shock hitting the KRW hard, likely due to heightened global risk aversion. Recent data indicates the USD has been gaining strength as a safe-haven asset amid Middle East tensions, with Brent crude oil jumping above $100/barrel, increasing pressure on energy-import-reliant economies like South Korea.

Primary Drivers and Economic Context

The significant movement favoring the USD is likely linked to escalating geopolitical stress, particularly concerning Middle East conflicts, which has fueled a flight-to-quality into the US Dollar. Higher oil prices resulting from these tensions disproportionately affect the KRW due to South Korea's heavy reliance on energy imports, increasing dollar demand. Furthermore, concerns over US trade actions, such as Section 301 investigations, and global risk-off sentiment have pressured Asian markets, including the KOSPI, leading to foreign selling of Korean assets, which further weakens the Won. While the US Federal Reserve faces a complex situation with persistent inflation but slowing labor market signs, the immediate global risk environment appears to be prioritizing USD strength. Meanwhile, the Bank of Korea must contend with potential imported inflation from rising energy costs, complicating its monetary policy stance.

Mid/Long-term Trends and Volatility Analysis

Analyzing the trend data reveals a clear strengthening of the USD against the KRW over the medium term. Over the last six months, the pair has risen by a substantial +7.17% (+99.84 KRW), with the current rate being the highest point in that period. The one-year change is also positive at +2.40% (+34.97 KRW), though less pronounced than the six-month surge.

Assessing stability:

• 1 Week: The Choppiness Efficiency of 0.18 suggests a somewhat choppy, less stable one-week trend, although the 0.60% volatility (SD) is moderate.
• 6 Months: The Efficiency of 0.13 indicates a strongly trending market over the past half-year, aligning with the significant +7.17% net change. The volatility at 0.55% (SD) is slightly lower than the weekly measure, suggesting the trend, despite being strong, has been relatively orderly in terms of daily price swings.
• 1 Year: The Efficiency of 0.02 is extremely low, implying the one-year period has been exceptionally choppy or directionless overall, despite the net appreciation seen in the 6-month window. The volatility (SD) is slightly higher at 0.61%, reflecting greater day-to-day instability over the full year.
