On April 29, 2026, the KRW/USD exchange rate recorded a daily decline of 0.101%, reflecting a stronger U.S. dollar and a weaker South Korean won. This movement was primarily driven by the won, which accounted for 59% of the attribution, compared to 41% for the dollar. The currency pair has been under pressure as geopolitical tensions in the Middle East drive up oil prices, exacerbating inflation concerns and increasing the energy import burden for South Korea. Furthermore, uncertainty regarding U.S. Federal Reserve monetary policy and the "hawkish hold" stance has sustained demand for the dollar, limiting room for won appreciation.

Mid-to-long-term trends reveal a market characterized by high choppiness and moderate volatility. Across the 1-week, 6-month, and 1-year periods, the efficiency metrics are consistently low (ranging from 0.02 to 0.06), indicating that the market is not following a clean, directional trend but is instead experiencing significant, directionless zigzagging. Volatility, measured by the standard deviation of daily returns, remains between 0.26% and 0.62%, suggesting a period of instability. Overall, the data points to a market struggling for clear direction, heavily influenced by shifting risk sentiment and external economic shocks rather than steady, fundamental growth.
