The Japanese yen and Swiss franc saw gains as currency markets opened following a weekend of major U.S. and Israeli strikes against Iran, which reportedly resulted in the death of Supreme Leader Ayatollah Ali Khamenei.

The euro depreciated by 0.34% against the dollar, trading at $1.1776. It also fell 0.5% versus the Swiss franc to its lowest point since 2015.

The dollar weakened against the yen, dropping 0.26% to 155.65 yen.

These events have sent ripples through the Middle East and global markets, impacting shipping, air travel, and oil, with concerns rising over energy costs and trade disruptions in the Gulf region. Analysts anticipate a sharp increase in oil prices and a potential rise in gold values, while stock markets are expected to open lower.
