Seoul, March 31 South Korean stocks traded lower late on Tuesday morning, led by heavy foreign sell-offs, as an escalating conflict in the Middle East heightened concerns about global oil supplies and broader economic impacts.
The benchmark Korea Composite Stock Price Index (KOSPI) fell 89.14 points, or 1.69 percent, to 5,188.16 as of 11:20 a.m.
The index opened about 3 percent lower and had been under downward pressure, though some of the earlier losses were erased, reports Yonhap news agency.
US President Donald Trump threatened to "completely obliterate" Iran's Kharg Island, a key oil hub, as well as its power plants and oil wells, if a peace deal with the United States is not reached "shortly."
Tehran, however, dismissed the peace proposals as "unrealistic, illogical and excessive," while a parliamentary security committee approved a draft bill to introduce a toll system for the Strait of Hormuz, according to foreign media reports.
The widening conflict pushed up global oil prices. U.S. West Texas Intermediate (WTI) crude futures for May delivery rose 3.25 percent to US$102.88 per barrel, surpassing the $100 mark on a closing basis for the first time since July 2022.
