SEOUL, March 24 (AJP) — South Korea’s benchmark KOSPI opened sharply higher on Tuesday upon expectation of a potential truce.

Seoul’s main index rose 4.39 percent to 5,643.00 at the open, while the KOSDAQ gained 3.47 percent to 1,135.00. Gains later pared to around 2 percent as conflicting remarks from Washington and Tehran over a possible truce tempered early optimism.

U.S. President Donald Trump delayed a potential strike on Iran by five days and signaled openness to negotiations, raising hopes for early de-escalation.

The rally was further supported by a sharp drop in oil prices and easing bond yields. West Texas Intermediate crude plunged 10.3 percent to the high-$80 range per barrel, while the U.S. 10-year Treasury yield slipped to around 4.34 percent.

The decline in oil prices reflected expectations of diplomatic progress and a normalization of supply, though volatility driven by geopolitical headlines is likely to persist.

Major KOSPI heavyweights moved broadly higher. Samsung Electronics rose 3.92 percent to 193,600 won, while SK hynix jumped 5.47 percent to 984,000 won. Hyundai Motor advanced 3.30 percent to 501,000 won, and LG Energy Solution gained 4.92 percent to 373,500 won.

Among other large caps, Samsung Biologics added 2.10 percent to 1,555,000 won. Hanwha Aerospace edged up 1.41 percent to 1,296,000 won, and Doosan Enerbility climbed 3.18 percent to 103,900 won.

Financials and industrials also traded higher. KB Financial Group gained 2.41 percent to 148,800 won, HD Hyundai Heavy Industries rose 2.99 percent to 517,000 won, and Samsung C&T climbed 3.10 percent to 283,000 won. Celltrion advanced 2.97 percent to 193,900 won, while Samsung Life Insurance added 2.76 percent to 223,500 won.

Shinhan Financial Group rose 1.22 percent to 91,000 won, Hanwha Ocean gained 3.11 percent to 122,600 won, and Mirae Asset Securities advanced 3.07 percent to 63,800 won. Hyundai Mobis increased 2.10 percent to 389,000 won, while HD Hyundai Electric jumped 3.83 percent to 948,000 won.

Kia was the only major decliner, falling 2.04 percent to 158,400 won.
