Global stock markets traded on a mixed note while international oil prices edged upward following an agreement between the United States and Iran to halt their latest weekend drone and missile exchanges, providing a tentative breather to a highly unstable Middle East truce. While the de-escalation raised hopes that Washington and Tehran will finalize a deal to reopen the strategic Strait of Hormuz, investor sentiment remained deeply fractured as energy supply anxieties clashed with a widening tech sell-off. Major equity hubs across Hong Kong, Shanghai, and Tokyo managed minor recoveries, but the market was simultaneously weighed down by a sharp warning from the Bank for International Settlements (BIS), which cautioned that the ongoing, multi-trillion-dollar corporate artificial intelligence expenditure boom risks turning into a protracted investment bust if commercial returns continue to disappoint.
