US Secretary of State Marco Rubio is navigating significant resistance from Gulf Arab leaders as he attempts to secure regional backing for Washington’s proposed Iran peace deal.

During a diplomatic tour of the United Arab Emirates, Kuwait, and Bahrain, Rubio is confronting deep-seated concerns that excessive concessions to Tehran could strengthen Iran’s regional influence and destabilize the balance of power.

The friction between Washington’s diplomatic objectives and Gulf security priorities is a critical variable for energy markets.

While the prospect of a nuclear deal typically reduces geopolitical risk premiums, the current lack of consensus among key regional allies suggests that shipping and supply chain risks in the Strait of Hormuz will remain elevated.

Markets are likely to maintain a cautious stance on oil prices until a unified regional position emerges.

Rubio’s itinerary, which runs through Thursday, aims to align Gulf states with the US strategy on ongoing nuclear negotiations.
