Gulf States Cautious as US-Iran Truce Sparks Uncertainty Over Hormuz Strait

The Gulf region breathed a sigh of relief on Tuesday after Iran and the United States agreed to a two-week truce, halting over five weeks of escalating attacks and hostile rhetoric.

However, Gulf states are expressing caution, concerned that the US, seeking a swift exit, might agree to terms granting Iran some control over the Strait of Hormuz, a vital waterway through which one fifth of the world's oil and natural liquefied gas passes.

Iran had nearly brought traffic through the strait to a standstill in response to joint US-Israeli attacks on its soil since February 28. Under the truce, Iran has agreed to halt attacks for two weeks in exchange for resumed maritime transit in the key waterway.

Despite this, Gulf Cooperation Council (GCC) countries are stressing that any deal must result in a permanent, long-term arrangement to keep the strait open. They fear a weakened yet intact Iranian leadership could use the strait as leverage, leaving them under constant threat of disruption and economic blackmail.

“There is a quiet but palpable concern that President Trump, eager for a quick political victory, could tolerate some Iranian leverage over the strait in exchange for a fragile truce, prioritising optics over Gulf realities,” said Hesham Alghannam, a Saudi Arabia-based scholar at the Malcolm H Kerr Carnegie Middle East Center.

The GCC countries, which have faced near-daily Iranian missile and drone attacks, have welcomed the truce but emphasize that the Strait of Hormuz must reopen. They are also concerned about Iran's future influence over the strait, with a Bahrain-sponsored UN Security Council resolution calling for countries to use defensive missions to keep the maritime chokepoint open being vetoed by Russia and China.

A further escalation could have devastating consequences for the GCC economies, undoing decades of work to make the region a safe hub for finance, tourism, and culture. Analysts say GCC countries have stepped up diplomacy in the lead-up to the conflict, but officials across the region have warned Iran should not mistake their inaction as a sign of weakness.

“The Gulf will leave no stone unturned if Iran continues to take the path of aggression,” said Hamad Althunayyan, a political analyst and professor at Kuwait University. “The Gulf expects its interests to be represented, and included, in any deal with Iran.”
