Diplomatic efforts to ease tensions between the United States and Iran stalled after Tehran announced it would not meet directly with U.S. negotiators who had traveled to the Middle East. The setback raises fresh uncertainty over the framework for de-escalation and restoring reliable shipping passage through the critical Strait of Hormuz.

The development casts a shadow over global markets, which had been optimistic about a resolution. The renewed diplomatic friction keeps geopolitical risk at the forefront for investors and places a renewed focus on energy market stability, even as crude oil prices remained relatively contained in early trading.
