Asian Stock Markets Strengthen Following Trump's Ultimatum to Iran Over Strait of Hormuz

Jakarta – Asian-Pacific stock markets strengthened during trading on Monday, 6 April 2026. The gains followed market participants digesting the latest developments in the Middle East conflict and recent statements from United States President Donald Trump.

The strengthening occurred amid the closure of many Asian markets for major religious holidays and regional festivals. Investors seized the opportunity to respond to the still-heating geopolitical dynamics.

According to CNBC International, Japan’s main index, the Nikkei 225, surged 0.62 per cent. The Topix index rose 0.23 per cent.

In South Korea, the Kospi index strengthened 1.8 per cent. The Kosdaq index, comprising small-capitalisation stocks, rose 0.98 per cent.

Market sentiment was driven by Trump’s latest statement, which again ramped up pressure on Iran. In his remarks on Sunday local time, Trump threatened to attack Iran’s electricity facilities and civilian infrastructure if Tehran did not promptly reopen the Strait of Hormuz.

Trump emphasised the ultimatum in a stern tone. He even warned of bringing “hell” to Iran following the successful US rescue of an American pilot in Iranian territory last week.

He also set a new deadline for Iran to reach an agreement with the US. The White House later confirmed that this timeframe was the latest deadline for Iran to reach a deal with Washington.

“Deadline Tuesday at 20:00 Eastern Time,” Trump wrote, without providing further details.

Trump is also scheduled to hold a press conference with military officials in the Oval Office on Monday afternoon local time. This has further heightened the attention of global market participants.

On the other hand, Iran rejected the ultimatum. The Tehran government stated that the Strait of Hormuz would only be fully opened after compensation for war damages is provided, and Iran has reportedly continued launching attacks on economic targets and infrastructure in the Gulf region, including Kuwait’s oil headquarters.
