Shares opened higher Friday, rebounding from sharp losses the previous session, as investors had guarded hopes for the reopening of the Strait of Hormuz amid a prolonged conflict in the Middle East.

After opening 2.7 percent higher, the Kospi rose 172.7 points, or 3.3 percent, to 5,406.75 in the first 15 minutes of trading.

During a prime-time address on Wednesday, U.S. President Donald Trump said the United States would hit Iran "extremely hard over the next two to three weeks" and "bring them back to the Stone Age," without providing a timeline for ending the conflict.

The warning of intensifying military operations dampened hopes for a swift resolution to the monthlong conflict, which has pushed up oil prices amid supply disruptions, rattled financial markets and fueled fears of inflation and a potential economic slowdown.

Iran's Deputy Foreign Minister Kazem Gharibabadi, however, said Tehran is drafting a protocol with Oman to monitor traffic through the Strait of Hormuz, which would require ships to obtain permits and licenses, according to foreign media reports.

The move raised hopes for progress in reopening the strategic waterway, which has effectively been shut since the start of the war in late February, and helped ease global oil prices.

Overnight, the Dow Jones Industrial Average fell 0.13 percent, while the Nasdaq composite rose 0.18 percent. The S&P 500 gained 0.11 percent.
