The reopening of the Strait of Hormuz has delivered an immediate boost to global markets and energy supply expectations, but insurance and credit risks tied to the recent conflict remain far from resolved.
According to a report from the BBC, oil prices fell sharply after Iran confirmed that the key shipping lane would be “completely open” to commercial vessels for the remainder of the ceasefire. Brent crude dropped to $88 per barrel, down from more than $98 earlier in the day and well below its March peak above $119.
Roughly 20% of the world’s oil and liquefied natural gas passes through the Strait of Hormuz, which had effectively been shut since late February following US and Israeli strikes on Iran. The disruption triggered a surge in energy prices, strained supply chains, and heightened geopolitical risk across global markets.
Equity markets responded positively to the reopening. Major US indices, including the S&P 500, Nasdaq, and Dow Jones Industrial Average, all posted gains in early trading, while European markets also rallied.
However, analysts caution that the reopening represents a short-term de-escalation rather than a lasting resolution.
Daniela Hathorn, senior market analyst at Capital.com, said the announcement should be treated carefully. “On the surface, this is clearly positive for markets. However, the key issue is credibility and durability,” she said. “The Strait has already moved between ‘open’ and ‘restricted’ multiple times during the ceasefire period.”
Hathorn noted that markets remain highly sensitive to headlines, with sharp relief rallies often followed by renewed volatility. “This development reduces immediate tail risk but does not eliminate it,” she added.
The reopening does little to immediately reduce elevated risk pricing, particularly in marine and trade credit lines of insurance.
Raj Abrol, CEO of Galytix, said underwriting conditions will lag behind market optimism. “Insurance premiums that spiked 50% won’t come down until underwriters believe the risk has genuinely changed,” he said. “The word ‘fragile’ matters here.”
Marine insurers, in particular, are expected to maintain heightened war risk premiums until safe passage through the Strait is consistently demonstrated. Early industry signals suggest operators remain cautious, with some tanker companies unwilling to resume transit immediately.
Moving forward, insurers will be looking at whether the Strait will remain reliably accessible in the weeks and months ahead. Until then, elevated premiums and volatility are likely to persist.
Logistical challenges also remain. During the closure, many shipping routes were diverted around Africa, increasing transit times and costs. These changes are not easily reversed, said Abrol.
“Supply chains that were rerouted around Africa don’t switch back overnight,” he said. “Lenders and businesses need sustained stability, not a two-week window.”
The disruption has also impacted fertilizer shipments (around a third of key global supplies pass through the Strait), raising concerns about agricultural output and food price inflation. Such knock-on effects continue to influence insurance exposures in sectors ranging from agribusiness to aviation.
Beyond insurance, the broader financial impact continues to weigh on businesses and households. Abrol pointed out that borrowing costs for lower-rated corporates have more than doubled since late February, while UK gilt yields reached 5% for the first time since 2008.
Mortgage markets have also tightened, with over 1,500 products withdrawn during the period of heightened uncertainty.
