South Korean Won Trading Volume Nears $14 Billion, Intraday Volatility Hits Three-Year Peak
The South Korean won’s currency trading volume surged to its highest level on record in March, driven by significantly heightened volatility in the foreign exchange market. Escalating geopolitical tensions, particularly the conflict in the Middle East, have fueled this sharp rise in forex activity.
Data compiled by the Seoul Money Brokerage Services and Korea Money Brokerage Corp. reveals that the average daily trading volume in the won-dollar spot market reached an impressive $13.92 billion last month.
This figure represents a substantial increase from historical trends. For over two decades, since the early 2000s, the won’s daily trading volume consistently remained below the $10 billion threshold. It first surpassed this mark in 2023, reaching $10.59 billion, before climbing further to exceed $13 billion in June last year and again in February this year. The recent surge in March, pushing turnover close to $14 billion, highlights a rapid expansion in South Korea’s currency market activity.
The significant spike in won trading can be largely attributed to increased foreign exchange market volatility. Intensifying tensions in the Middle East have unsettled global financial markets, leading to heightened risk aversion among investors.
Elevated periods of currency volatility typically stimulate heavier trading volumes, as various market participants react to the dynamic environment. Some investors actively pursue arbitrage strategies to capitalize on short-term price swings, while others increase their hedging activities to mitigate potential currency risks. Greater uncertainty surrounding the exchange rate’s direction also tends to trigger a higher frequency of transactions, thereby boosting overall market turnover.
Recent statistics from the Bank of Korea underscore the extent of these market fluctuations. The won’s average intraday movement reached 11.4 won per dollar in March, marking the largest daily swing in over three years since November 2022, when it registered a 12.3 won movement.
During that earlier period, the South Korean currency experienced sharp strengthening amid expectations of a shift by the US Federal Reserve away from aggressive monetary tightening policies. In stark contrast, the current wave of won volatility is primarily driven by geopolitical uncertainty and shifts in broader global risk sentiment.
The won has also demonstrated a clear weakening trend over recent months. It averaged 1,486.64 per dollar in March, a depreciation from 1,449.32 per dollar in February. More recently, daily fluctuations of 20 to 30 won have become increasingly common, often triggered by developments related to the Middle East conflict, including remarks from influential figures like US President Donald Trump.
With the ongoing conflict in Iran expected to persist, market analysts predict that won volatility is likely to remain elevated in the near term.
Oh Jae-young, an analyst at KB Securities, commented, “The exchange rate is currently influenced by a confluence of factors including ceasefire expectations, global oil price movements, shifts in investor risk appetite, and foreign capital flows within Korea’s stock and bond markets.”
He further added, “From April onward, the conflict’s impact is expected to be increasingly reflected in inflation and trade data. Even if the conflict eventually subsides, significant volatility is projected to persist at least through May.”
Some analysts caution that the downside risks for the South Korean currency could intensify if geopolitical tensions fail to ease. Choi Kwang-hyeok, an analyst at LS Securities, warned that the won could potentially weaken to as much as 1,600 per dollar if the Iran conflict extends beyond April.
Choi stated, “The current geopolitical situation could exert further depreciation pressure on the won.”
He also highlighted deeper structural concerns, noting a gradual weakening trend in the currency over time.
“The won’s baseline has been trending weaker, suggesting a potential deterioration in Korea’s underlying economic fundamentals,” he explained. “This makes the situation more concerning than a short-term fluctuation solely driven by external events.”
The combination of persistent geopolitical risks, capital flow volatility, and underlying structural pressures indicates that the South Korean won may remain under considerable strain, even beyond the immediate impact of the Middle East conflict.
