Seoul, April 3 (NationPress) – South Korean equities surged nearly 2.5% on Friday morning as reports indicate that Iran is negotiating a protocol with Oman to oversee traffic in the Strait of Hormuz, instilling optimism for the reopening of this vital shipping lane.
The benchmark Korea Composite Stock Price Index (KOSPI) increased by 128.99 points, equivalent to 2.46 percent, reaching 5,363.0, according to the Yonhap news agency.
The index commenced with a 2.7 percent rise, bouncing back from a significant drop in the previous session, and sustained its upward trajectory due to robust buying from institutional investors.
Despite high concerns regarding escalating conflicts in the Middle East, particularly after U.S. President Donald Trump's prime-time address on Wednesday (U.S. time), where he stated that the U.S. would respond to Iran with severe measures over the next two to three weeks, no timeline was given for ending the ongoing conflict that began in late February.
Iran's Deputy Foreign Minister Kazem Gharibabadi announced that Tehran is in the process of drafting a protocol with Oman to monitor traffic in the Strait of Hormuz, which raises hopes for reopening this crucial waterway, effectively closed since the onset of the war.
In Seoul, large-cap technology stocks propelled the index's rise, with market leader Samsung Electronics climbing by 3.28 percent and semiconductor giant SK Hynix soaring 5.18 percent.
Top automotive manufacturer Hyundai Motor saw a rise of 1.29 percent, while its affiliate Kia edged up 0.2 percent.
Defense contractor Hanwha Aerospace gained 2.05 percent, and artificial intelligence investment company SK Square increased by 1.06 percent. Additionally, nuclear power plant construction firm Doosan Enerbility jumped 3.42 percent.
Shipbuilding stocks also made significant gains, with industry leader HD Hyundai Heavy surging 9 percent, while its competitor Hanwha Ocean climbed 5.62 percent.
However, leading battery manufacturer LG Energy Solution dipped 0.87 percent, and biotech giant Samsung Biologics fell 1.77 percent. Financial powerhouse KB Financial experienced a slight decline of 0.07 percent.
Point of View
The surge in South Korean stocks reflects a cautious optimism in the wake of geopolitical tensions. Investors seem to be responding positively to potential diplomatic efforts, despite the ongoing conflicts in the region. Our focus should remain on the implications for both local and global markets.
