Iran has signaled that peace negotiations with the United States are no longer viable following a fresh escalation of Israeli military operations in Lebanon.

The diplomatic stalemate introduces fresh uncertainty into an already fragile geopolitical landscape.

Markets are for potential spillover effects on energy supplies, shipping routes, and risk sentiment across European and US equities.
