Iran has declared peace negotiations with the United States pointless following a fresh escalation of Israeli military operations in Lebanon, casting immediate doubt on the viability of a diplomatic resolution to the regional crisis.

The announcement comes as Washington continues to press for a breakthrough agreement by Sunday, coinciding with Donald Trump’s 80th birthday.

The breakdown in dialogue marks a significant deterioration in the diplomatic track, which had previously been the primary mechanism for de-escalating tensions after Iran launched missiles at Israel earlier this week.

Israeli forces have since retaliated with strikes on Iranian military targets, while simultaneously intensifying operations in Lebanon, creating a multi-front conflict that has overwhelmed the fragile ceasefire framework.

This development fundamentally alters the market backdrop for energy and defense sectors.

The collapse of the immediate diplomatic window removes the near-term ceiling on geopolitical risk premiums.
