Thailand has become the first Southeast Asian nation to secure safe passage for its oil tankers through the Strait of Hormuz, following a diplomatic agreement with Iran. [1] Prime Minister Anutin Charnvirakul announced the deal on March 28, saying "an agreement has been reached to allow Thai oil tankers to transit safely through the Strait of Hormuz." [2]

A Thai oil tanker belonging to Bangchak Corporation safely transited the strait on March 25, following diplomatic coordination between Bangkok and Tehran. [3] A second Thai vessel has since been granted permission to pass. [4]

The agreement is a diplomatic breakthrough for Thailand — and a potential blueprint for other Southeast Asian nations. Malaysia has reportedly reached a similar arrangement. [5] The Philippines, which declared a national energy emergency on March 24, has not yet announced a deal.

Analysts say Iran's willingness to grant passage to Southeast Asian vessels is calculated. By allowing neutral ASEAN nations through the strait, Iran positions itself as a reasonable actor — distinguishing between countries it considers hostile (the US, Israel, their allies) and countries it considers neutral.

The deal does not solve Thailand's energy crisis. The country still faces elevated fuel prices, supply chain disruptions and the risk that the agreement could be revoked if diplomatic relations sour. But it is a lifeline that most of Southeast Asia does not have.

For the Philippines, Cuba and Kenya — all suffering fuel emergencies with no negotiated passage — Thailand's deal is a reminder that the Hormuz closure is not uniform. It is selective. And selectivity is a form of power.
