Asian markets gave up early gains and mostly swung to losses, as investor confidence wavered on media reports that the U.S. has intercepted at least three Iranian oil tankers in Asian waters, heightening uncertainty that the Middle East conflict may drag on.
Earlier in Thursday’s session, Japan and South Korea stocks hit record highs, trailing overnight gains on Wall Street after President Donald Trump’s extended a ceasefire with Iran, boosting investor sentiment alongside strong corporate earnings.
The U.S. military has intercepted at least three Iranian-flagged tankers in Asian waters and is redirecting them away from positions near India, Malaysia and Sri Lanka, shipping and security sources said on Wednesday.
This followed Iran’s navy saying it had seized two container ships in the Strait of Hormuz.
Trump extended a two-week U.S. ceasefire on Tuesday, saying it was warranted due to Tehran’s “seriously fractured” government.
“Based on the fact that the Government of Iran is seriously fractured, not unexpectedly so and, upon the request of Field Marshal Asim Munir, and Prime Minister Shehbaz Sharif, of Pakistan, we have been asked to hold our Attack on the Country of Iran until such time as their leaders and representatives can come up with a unified proposal,” Trump said in a Truth Social post.
The ceasefire will remain in place until Iran submits a proposal or talks conclude, while the U.S. military continues its blockade of Iranian ports, Trump said.
However, the timeline remains uncertain. Iranian state media reported Wednesday that Tehran’s negotiators would not attend talks with the U.S., calling them a “waste of time.” A lack of commitment from Iran reportedly prompted Vice President JD Vance to pause his trip to join peace talks.
