Asia-Pacific markets set to fall as investors brace for escalating tensions in Mideast

In this articleAsia-Pacific markets were set to fall on Monday as investors weighed escalating tensions in the Middle East after the U.S. and Iran threatened to intensify military hostilities as the war entered its fourth week.

President Donald Trump said on Saturday that he would "obliterate" Iran's power plans if Tehran failed to fully reopen the Strait of Hormuz — a vital artery for global energy flows — within 48 hours Iran pushed back, threatening to target energy infrastructure and desalination facilities in the Gulf if the U.S. carries out its ultimatum. Iran's Parliament speaker Mohammad Bagher Ghalibaf said Saturday that attacks on the country's power plants would "immediately" be met with retaliatory strikes on energy and oil infrastructure across the region. "Critical infrastructure and energy and oil infrastructure throughout the region will be considered legitimate targets and irreversibly destroyed, and oil prices will rise for a long time," Ghalibaf said on X.On Sunday, Ghalibaf extended the threat to U.S. treasury holders, warning financial entities that purchase American government bonds and "finance the U.S. military budget" would be considered legitimate targets, alongside military bases.
