Global markets show jitters as U.S.-Iran tensions escalate and uncertainty spreads across currencies and rates. Multiple reports say the U.S. dollar strengthens while cracks appear in a Middle East peace effort, amid concerns that President Donald Trump threatens to restart conflict in the region and that Iran’s actions further raise the risk of disruption. Both accounts link the market strain to heightened pressure around oil trade and the Strait of Hormuz, including Tehran closing the strait, which contributes to worries about energy supply.

In the currency markets, the British pound weakens, with sources citing political uncertainty tied to UK leadership dynamics. One report specifically mentions uncertainty involving Labour leader Sir Keir Starmer. The Japanese yen also edges near a two-year low, with authorities monitoring market moves.

On interest rates, U.S. Treasury yields rise, reflecting expectations that further interest rate hikes could follow. Market participants appear to be reassessing risk as geopolitical developments influence oil prices and broader financial conditions.
