Strait of caution: experts and insurers throw cold water on US-Iran reopening hopes

Despite official announcements from Iran and the US declaring the Strait of Hormuz reopened, maritime experts and traders remain deeply skeptical about the optimistic timeline, with data indicating no significant movement of previously trapped ships and expectations that normal shipping traffic may take three to four months to resume. Jakob Larsen, chief safety and security officer at BIMCO, highlights a critical disconnect between these statements and the operational realities, noting that key details such as safe routes, naval protection, and assurances of mine-free waters remain unclear, which fuels continued caution within the shipping industry.

This skepticism is further reinforced by the cautious stance of insurers and political risk analysts who emphasize that a sustained period of calm is necessary before risk appetite in the region can improve. David Kinzel of Aon plc underscores the uncertainty surrounding the truce’s impact on the Strait’s security, reflecting broader market doubts about whether the de-escalation will hold and when normalized shipping might realistically resume, thereby prolonging operational hesitancy despite the ceasefire.

Despite official announcements declaring the Strait of Hormuz reopened, maritime insurers have yet to resume coverage for vessels transiting the area, creating a classic 'chicken-and-egg' dilemma that effectively keeps most ships anchored. Jakob Larsen, chief safety and security officer at BIMCO, highlights that the lack of clear information on safe routes, naval protection, and mine clearance perpetuates a cautious stance among shipowners, who continue to view the security situation as volatile and risky. This persistent uncertainty underscores why, even months after the ceasefire, full operational resumption remains elusive.

The insurance market's hesitancy to increase exposure in the Strait of Hormuz region reflects deep-seated doubts about the durability of the U.S.-Iran truce and the overall security environment. David Kinzel, political risk U.S. practice leader at Aon plc, emphasizes that insurers require a sustained period of calm before underwriting risks anew, signaling that the ceasefire has yet to translate into improved risk appetite. This cautious approach by insurers not only delays the normalization of shipping activities but also highlights the fragile nature of the current geopolitical détente.

Oil prices have experienced significant volatility amid the US-Iran ceasefire talks, reflecting a market caught between optimism and caution. While Brent crude fell over 20% from recent peaks to below $85 per barrel following ceasefire announcements, futures contracts extending into 2027 have remained largely unchanged, signaling skepticism about a swift return to pre-conflict price levels. Analysts like those at Citigroup have adjusted forecasts downward, predicting Brent could average as low as $70 per barrel by late 2026, yet operational realities such as mine clearance and insurance hesitancy continue to delay full supply restoration, sustaining price pressures.

The disconnect between speculative futures markets and physical oil prices has been stark throughout the conflict period. David Blackmon highlighted that while Brent futures hovered around $90 to $100, physical deliveries to some U.S. refineries reached as high as $140 per cargo, underscoring logistical bottlenecks and insurance market reluctance to fully reopen shipping lanes. This divergence reflects the complex interplay of geopolitical risk, operational delays in the Strait of Hormuz, and cautious market sentiment awaiting concrete peace deal terms and safe passage assurances.

Geopolitical dynamics beyond the US-Iran ceasefire continue to inject uncertainty into oil markets, with ongoing defensive military activity in Iran and regional conflicts such as fighting in Lebanon complicating the outlook. The US administration's pursuit of a diplomatic off-ramp contrasts with divergent narratives on sanctions and nuclear issues, keeping investors wary. This persistent tension, combined with demand-side factors like China’s 29% year-over-year drop in crude imports, contributes to a fragile equilibrium where oil prices remain sensitive to both supply disruptions and shifting global demand.

Market reactions to ceasefire progress have been swift but tentative, with oil prices initially surging on hopes for normalized shipping through the Strait of Hormuz and potential lifting of Iranian sanctions, only to retreat amid skepticism about the timeline for full operational recovery. Despite President Trump's repeated assurances that energy prices would 'drop like a rock,' experts caution that clearing mines, restarting production, and replenishing reserves will keep prices elevated for years. As David Blackmon notes, the normalization of trading patterns and tanker movements is a gradual process, meaning that immediate price drops may be more feather-like than rock-like.

The recent memorandum of understanding extending the US-Iran ceasefire by 60 days triggered a notable 10% drop in oil prices and a 10 basis point decline in treasury yields, underscoring how deeply intertwined the conflict's trajectory is with global economic indicators. However, despite these initial market reliefs, President Trump’s acknowledgment that negotiations remain ongoing with no definitive timeline injects continued uncertainty, keeping investors cautious amid volatile geopolitical conditions.

Regional stability remains fragile as defensive kinetic activities in Iran and renewed fighting in Lebanon exacerbate tensions, complicating efforts to normalize shipping through the Strait of Hormuz. This persistent instability dampens risk appetite, with experts like David Kinzel of Aon plc emphasizing that insurers require a prolonged period of calm before increasing their exposure, thereby delaying any meaningful recovery in Middle Eastern market confidence.
