Currency – South Korean Won Slides as Oil Prices Rise Amid Middle East Tensions
Currency – The South Korean won weakened against the US dollar on Thursday as rising global oil prices unsettled financial markets. The decline came amid growing concerns that escalating tensions in the Middle East could disrupt oil supplies, creating uncertainty for countries heavily dependent on imported energy, including South Korea.

Financial data showed the won opening at 1,480.1 per dollar, marking a drop of 13.6 won compared with the previous trading session. The movement reversed gains seen earlier in the week when the currency had briefly recovered from a 17-year low.
Rising Oil Prices Trigger Market Concerns
Energy markets have experienced renewed volatility following developments in the Middle East that raised fears about potential disruptions to global oil supply routes. Oil prices climbed after reports that Iran had effectively halted cargo traffic through the Strait of Hormuz, one of the world’s most critical oil transit channels.
According to international reports, Iranian forces targeted commercial vessels and also struck Dubai International Airport, escalating tensions in the Persian Gulf region. These actions increased uncertainty about shipping safety and the stability of energy supply chains, pushing oil prices higher in global markets.
Higher crude prices often place pressure on currencies in countries that rely heavily on imported energy. South Korea is one of the world’s largest importers of crude oil, which means rising prices increase demand for US dollars used to purchase energy supplies abroad. This dynamic contributed to the won’s depreciation during Thursday’s trading session.
Earlier Gains Reversed After Temporary Stability
The currency had strengthened slightly over the previous two days before Thursday’s decline. Market sentiment had improved after comments from US President Donald Trump suggesting that the ongoing conflict in the Middle East might reach a resolution in the near future.
At the same time, global oil prices had shown signs of stabilizing earlier in the week, helping ease pressure on the Korean currency. The brief recovery allowed the won to bounce back from levels not seen in nearly two decades.
However, renewed concerns about supply disruptions quickly reversed that momentum, sending the currency lower again as oil prices resumed their upward climb.
Global Measures Attempt to Ease Supply Concerns
Efforts have been made by international authorities to counter the potential impact of supply disruptions. The International Energy Agency announced the release of a record oil stockpile totaling 400 million barrels in an attempt to stabilize markets and maintain adequate supply.
In addition, the United States confirmed plans to release 172 million barrels from its Strategic Petroleum Reserve beginning next week. These measures are intended to offset possible shortages and prevent extreme price spikes in global energy markets.
Despite these steps, investors remain cautious as geopolitical tensions continue to influence trading activity across currencies, commodities, and equity markets.
Stock Market Reflects Investor Caution
South Korea’s stock market also reacted to the uncertainty. The benchmark Korea Composite Stock Price Index opened lower on Thursday, reflecting overnight declines on Wall Street and broader concerns about the potential economic consequences of a prolonged regional conflict.
The index started the session down 0.75 percent at 5,567.65. By 9:15 a.m., it had dropped 39.38 points, or about 0.7 percent, to 5,570.57. The decline followed a strong performance a day earlier when the market had climbed 1.4 percent.
Investors are closely watching developments in the Middle East, as continued instability could influence global trade flows, energy costs, and economic outlooks worldwide.
Currency and Energy Markets Remain Sensitive
Analysts note that fluctuations in oil prices often have immediate effects on currencies tied to energy imports. For South Korea, rising crude costs can quickly translate into increased demand for foreign currency, particularly US dollars, which tends to weaken the won.
With geopolitical tensions still evolving, financial markets are expected to remain sensitive to developments in energy supply routes and diplomatic efforts aimed at easing regional conflicts.
