A proposed peace agreement between the United States and Iran has raised hopes that one of the world’s most critical maritime chokepoints, the Strait of Hormuz, could soon reopen to normal shipping. However, diplomats and maritime experts caution that signing a ceasefire memorandum may be only the first step.
Disagreements over transit fees, concerns about naval mines, elevated insurance costs, and lingering security risks could delay a full return to normal operations for weeks or even months.
The Strait of Hormuz carries a significant share of the world’s seaborne oil and liquefied natural gas (LNG), making its stability essential for global energy markets and international trade.
Why is the Strait of Hormuz so important?
The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. An Iran-Oman mechanism is currently in place under the new Persian Gulf Strait Authority, requiring vessels to apply and disclose ownership, cargo, and insurance.
It is one of the world’s most strategically important waterways because
- A large share of globally traded crude oil passes through it.
- Major LNG exporters rely on the route.
- It serves as the primary export corridor for Gulf energy producers.
- Any disruption can immediately affect global oil prices and shipping costs.
Because there are few practical alternatives for moving Gulf energy supplies, even temporary disruptions can have worldwide economic consequences.
What does the proposed Iran-US agreement say?
According to reports, the United States and Iran have reached a memorandum of understanding (MoU) intended to end recent hostilities.
The reported framework includes:
- A ceasefire between the two sides.
- A gradual reduction of U.S. military operations related to the conflict.
- Steps toward restoring commercial navigation through the Strait of Hormuz.
- Continued negotiations on broader issues, including Iran’s nuclear and missile programs.
However, officials from both countries have yet to publicly release a final, jointly approved agreement.
What is the dispute over ‘tolls’ versus ‘service charges’?
One of the biggest disagreements centers on what commercial ships should pay to transit the strait.
The U.S. position
According to reports, Washington wants:
- Immediate reopening of the waterway.
- Permanent toll-free navigation.
- Unrestricted access for international shipping.
The United States argues that charging transit fees could conflict with principles of international maritime navigation.
Iran’s reported position
Iran reportedly distinguishes between the following:
- Transit tolls, which it says it may not impose.
- Service charges, which would cover navigation assistance, maritime safety, environmental protection, and administrative services.
Iran also reportedly intends to maintain oversight of vessel registration, cargo declarations, ownership information, and insurance documentation through a regional maritime management mechanism.
Whether these charges are viewed as legitimate service fees or prohibited transit tolls remains a major point of negotiation.
Could naval mines delay shipping?
Even if political agreement is reached, physical safety remains another challenge.
Reports indicate that naval mines laid during the conflict could require extensive clearance operations before shipping fully resumes.
Mine clearance is among the most technically demanding naval missions because:
- Each suspected minefield must be surveyed individually.
- Commercial shipping lanes require extensive verification before reopening.
- Weather and underwater conditions can slow operations.
- Maritime authorities must certify routes as safe for navigation.
Some analysts estimate that complete mine clearance could take several weeks or, in more complex scenarios, several months.
Why aren’t shipping companies returning immediately?
For shipping operators, the biggest concern is risk rather than politics.
Commercial vessel owners consider several factors before resuming regular operations:
- Security threats.
- Insurance costs.
- Availability of naval escorts.
- Port operations.
- Confidence that the ceasefire terms will hold.
Marine insurers have significantly increased war-risk premiums during the conflict.
Even after hostilities end, insurers typically wait for an extended period of incident-free navigation before reducing premiums.
That means shipping costs could remain elevated long after diplomatic agreements are signed.
How quickly could normal shipping resume?
The timeline depends on several factors.
Initial reopening
Commercial vessels could begin returning relatively soon after the implementation of a formal agreement if maritime authorities declare portions of the route safe.
Partial recovery
Container shipping may gradually increase as confidence improves and insurers reassess risks.
Full normalization
A complete return to pre-conflict traffic levels could take considerably longer, depending on:
- Mine clearance.
- Security verification.
- Insurance pricing.
- Political stability.
- Compliance with the ceasefire agreement.
LNG carriers, which often operate under stricter risk assessments, may take longer to resume normal schedules.
What happens next?
While the reported memorandum represents a significant diplomatic breakthrough, reopening one of the world’s busiest maritime corridors involves far more than signing a political agreement.
Successful implementation will likely require:
- Maritime security coordination.
- Verification that shipping lanes are safe.
- Agreement on navigation rules and applicable fees.
- Continued diplomatic engagement.
- Confidence from shipping companies and global insurers.
Until those conditions are met, commercial traffic through the Strait of Hormuz is expected to recover gradually rather than immediately.
TL;DR
- The U.S. and Iran have reportedly agreed on the framework of a ceasefire memorandum, but implementation challenges remain.
- Washington wants unrestricted, toll-free navigation through the Strait of Hormuz.
- Iran reportedly insists on retaining administrative control and charging service fees for maritime support.
- Naval mines and security concerns may delay a full reopening.
- Shipping companies and insurers are expected to remain cautious even after any agreement is signed.
- Energy markets will closely watch how quickly commercial traffic returns.
