Global markets traded lower on Tuesday as renewed military escalation between the US and Iran raised concerns over global energy supplies, driving oil prices higher and increasing expectations that major central banks could maintain tighter monetary policies.
Investors remained focused on US inflation data due later Tuesday amid growing concerns that higher energy prices could fuel inflation and push bond yields higher.
US President Donald Trump said the American blockade in the Strait of Hormuz has been reinstated, while a 20% transit fee will be imposed on all vessels transiting through the waterway.

The escalation also intensified fears of disruptions to global energy supplies through the strategic waterway, adding to inflation concerns and risk aversion in financial markets.
