Asia-Pacific markets are expected to fall on Monday as investors weigh the impact of escalating tensions between the U.S. and Iran in the Middle East. The tensions have intensified after the U.S. threatened to "obliterate" Iran's power plants if Tehran fails to reopen the Strait of Hormuz, a vital global energy chokepoint. Iran has pushed back, threatening to target energy infrastructure and desalination facilities in the Gulf region if the U.S. carries out its ultimatum.

Why it matters

The rising tensions in the Middle East have the potential to disrupt global energy supplies and roil financial markets, particularly in the Asia-Pacific region which is heavily dependent on energy imports. Any military conflict or disruption to oil and gas flows through the Strait of Hormuz could lead to a spike in crude prices, hurting energy-importing economies.

The details

President Donald Trump said on Saturday that the U.S. would "obliterate" Iran's power plants if Tehran failed to fully reopen the Strait of Hormuz within 48 hours. In response, Iran's Parliament speaker Mohammad Bagher Ghalibaf threatened to target energy infrastructure and desalination facilities in the Gulf, as well as financial entities that purchase U.S. government bonds. Crude prices were largely stable in early trading on Monday, with Brent crude down 0.25% and WTI down 0.6%.

  • On Saturday, President Trump issued a 48-hour ultimatum for Iran to reopen the Strait of Hormuz.
  • On Saturday, Iran's Parliament speaker Ghalibaf threatened retaliatory strikes on energy and oil infrastructure in the region.
