Maritime Risks in the Strait of Hormuz Remain Severe Despite Diplomatic Progress

The Strait of Hormuz remains one of the world's highest-risk maritime chokepoints despite recent diplomatic efforts aimed at reopening this strategically important waterway. Reports of explosions in the area, continued reliance on military assistance for vessel movements, and uncertainty surrounding the timeline for a full resumption of commercial shipping all indicate that the situation remains highly complex.

On Monday, multiple explosions were reported in the vicinity of the strait. At the same time, reports emerged that Iranian forces had fired upon a vessel attempting to transit the waterway. Industry sources indicated that vessels lacking authorization from the Persian Gulf Security Authority (PGSA) are still unable to transit under normal procedures, while some ships are operating under the protection of U.S. military escorts.

The U.S. military has also issued guidance advising shipping companies and vessel operators not to dispatch vessels through the Strait of Hormuz until a formal peace agreement between Washington and Tehran is officially signed. Meanwhile, the Joint Maritime Information Center (JMIC), part of the U.S.-led Combined Maritime Forces, continues to classify the threat level in the region as "severe" despite encouraging diplomatic developments.

A JMIC representative noted: "Mariners should expect increased naval presence, enhanced force protection postures, potential VHF hailing and congestion near anchorage areas."

Positive Signals from the Diplomatic Front

Despite ongoing security concerns, the market has begun to see signs that maritime operations may gradually resume.

Iranian state media reported that several Iranian vessels had successfully transited through the U.S. naval exclusion zone in the Gulf of Oman following a preliminary agreement between the two sides.

Speaking on the sidelines of the G7 Summit in France, U.S. President Donald Trump suggested that shipping activity was gradually resuming.

He stated: "The strait is already partially open. They are doing a little hunting for a couple of mines that they’ve already found."

President Trump also commented: "Ships are starting to go out. On Friday, it’ll be completely open."
Meanwhile, Vice President JD Vance indicated that an official announcement could come sooner than expected, suggesting that details of the agreement may be released before the formal signing takes place.

Market Participants Remain Cautious

In contrast to the optimism expressed by political leaders, the global shipping community continues to take a cautious approach.

Charu Chanana, Chief Investment Strategist at Saxo Markets, said: "Even as the market reacts to Hormuz opening headlines cleanly, the operational reality is likely to be messier."

According to Chanana, several practical obstacles remain: "Mine-clearing, insurance costs, port congestion and the risk of geopolitical spoilers could all keep barrels moving more slowly than the headline suggests."

Shipping broker BRS shares a similar view, arguing that even if a formal agreement is signed and remains in force, the restoration of traffic through Hormuz will likely occur in stages.

In its latest market assessment, BRS stated: "All told, if the deal is signed on Friday and then holds, we suggest that it should take four to five months for maritime traffic to return to normal in the strait."

This suggests that a full recovery of shipping activity through Hormuz is unlikely in the near term.

Biofouling Emerges as a New Operational Challenge After More Than 100 Days of Disruption

Even if security conditions improve, the shipping industry faces another significant technical challenge: biofouling.

Current estimates indicate that more than 500 vessels have been stranded or forced to wait at anchor in the Gulf region since the crisis began in late February. Many ships have remained idle or drifting for months in one of the world's hottest marine environments.

Sea surface temperatures in both the Persian Gulf and Gulf of Oman frequently exceed 30°C during the summer months, creating ideal conditions for the growth of barnacles, algae, biofilms, and other marine organisms on vessel hulls.

Under normal operating conditions, anti-fouling coatings are designed to perform effectively when vessels maintain regular sailing speeds. However, prolonged periods at anchor or reduced operational activity significantly diminish the effectiveness of these coatings, increasing the likelihood of marine growth accumulation.

Industry studies have shown that even moderate hull fouling can increase fuel consumption by 15% to 30%, with more severe cases resulting in even greater inefficiencies.

As a result, vessel operators could face substantially higher fuel costs and overall operating expenses. Shipping lines hoping to rapidly redeploy vessels once the market reopens may instead encounter increased fuel consumption and reduced operational efficiency during the early stages of recovery.

Compliance Challenges at Destination Ports

In addition to higher operating costs, biofouling creates significant regulatory compliance risks.

Australia, New Zealand, and several jurisdictions in the United States enforce strict biosecurity regulations aimed at preventing the introduction of invasive marine species through vessel hulls.

Ships that have remained idle in the Gulf region for extended periods may face:

●    Underwater hull inspections

●    Mandatory hull cleaning requirements

●    Delays in port clearance procedures

●    Operational restrictions until regulatory requirements are fully satisfied

This challenge is particularly significant given the relatively limited availability of hull-cleaning and underwater inspection services across the Middle East. Should Hormuz fully reopen and large numbers of vessels simultaneously return to service, demand for biofouling inspections and remediation could surge sharply, placing substantial pressure on regional marine service providers.

The Market Still Needs More Time

Although prospects for reopening the Strait of Hormuz are becoming increasingly tangible, most shipping companies are not yet prepared to declare the crisis over.

From mine-clearing operations and maritime security assessments to fleet redeployment and the management of operational consequences such as biofouling, the global shipping industry still faces considerable work before this critical maritime artery can return to stable operations.

Even under the most optimistic scenario, many industry experts believe it will take several more months before shipping volumes through Hormuz recover meaningfully, while a return to pre-crisis activity levels may ultimately become a story for 2027 rather than 2026.
