Declining Traffic and New Regulations in the Strait of Hormuz

Recent Transit Figures
Preliminary data from ship-tracker Kpler show five commodity vessels transited the Strait on August 25, matching the four vessels on August 24 and the five on August 10—well below the 10-day average of 15 vessels. The low counts contrast with the pre-war baseline, when roughly one-fifth of global crude oil and LNG passed through the waterway.
Diplomatic Moves Toward a Temporary Corridor
Iranian Foreign Ministry officials and Omani Foreign Minister Badr Albusaidi met in Tehran on August 25 to discuss a “phased framework” for a joint temporary navigation corridor and a mine-clearing project. The joint statement said the talks aimed to create a practical basis for moving forward and to respect the sovereignty of both coastal states. Both sides also signaled intent to negotiate a permanent corridor and a mechanism for exchanging navigation-traffic information.
New Iranian Regulatory Actions
The Persian Gulf Strait Authority (PGSA) issued a “Non-Compliant Vessels” list that includes 46 ships registered under 17 flag states, with 21 flagged to Liberia and seven to the Marshall Islands. Vessels on the list face possible fines, detention, seizure, or denial of future transits. The PGSA warned that any ship cooperating with listed vessels—through ship-to-ship transfers or transshipment—will itself be added to the list.
In parallel, the Iranian Parliament’s National Security and Foreign Policy Commission approved Article 3 of a bill authorizing fees for services such as navigation assistance, environmental protection, fuel supply, insurance and safety. Fees may be paid in Iranian rials or another designated currency, and the provision awaits full parliamentary approval.
Official Positions
- Iran maintains that the strait will remain closed until the United States lifts its naval blockade, drops oil sanctions and releases Iranian assets.
- Oman emphasizes respect for international law and the sovereignty of neighboring states while supporting the joint corridor framework.
- United Nations Secretary-General Antonio Guterres offered a neutral facilitation mechanism for fertilizer shipments, contingent on agreement by all conflict parties.
Conflicting Reports & Gaps
- Kpler reported a 10-day average of 15 commodity vessels, while Vortexa’s provisional data estimated roughly 5 million barrels per day of oil moved on August 25, with a seven-day average of 6–7 million barrels per day as of August 23. The two sources differ on the volume of oil transiting the strait.
- The exact number of vessels already fined or detained under the new PGSA regulations is not disclosed, leaving uncertainty about enforcement intensity.
Why It Matters
The combination of sharply reduced traffic, a pending fee regime, and an expanding blacklist heightens operational risk for global shipping firms and could further constrain energy supplies that already account for a significant share of world oil and gas exports. The diplomatic initiative between Iran and Oman offers a pathway to restore some level of normalcy, but its success hinges on broader geopolitical developments, notably U.S. sanctions policy and regional acceptance of the UN-proposed facilitation mechanism.
What’s Next
- Iran and Oman are expected to announce the formal details of the temporary corridor in the coming weeks.
- The PGSA will continue updating the Non-Compliant Vessels list, with ship owners advised to review it before chartering.
- U.S. Treasury Secretary Bessent indicated that additional sanctions will be announced imminently, potentially affecting entities that engage with the listed vessels.
These developments will shape the future of maritime traffic through one of the world’s most critical energy chokepoints.
