Key Takeaways:
A.P. Moller-Maersk A/S is closely monitoring the Strait of Hormuz after Iranian threats, as a new US naval blockade raises the risk profile in a waterway handling about a fifth of the world’s daily oil supply. The Danish shipping giant said the safety of its crews, vessels, and customer cargo remains its highest priority.
"We have noted Iran's statement regarding the Strait of Hormuz," a Maersk spokesperson said in a statement. "Our crew, vessels, and customers' cargo safety remains our priority."
The US blockade, which began April 13, targets vessels entering or leaving Iranian ports while allowing neutral ships to transit the strait. US Central Command reported that in the first 48 hours, nine Iran-linked ships complied with orders to turn back, and no commercial vessels evaded the cordon. The blockade follows failed diplomatic talks in Pakistan and is designed to cut off Iran’s economic jugular after it refused US demands.
The move escalates a conflict that has already seen Iran use its control over the strait to disrupt global trade, sending gas prices soaring and creating broad economic uncertainty. While analysts at Linerlytica note the direct impact on container shipping is "negligible" because traffic was already limited to Iranian-linked ships, the risk to oil and chemical tankers is severe. The Red Sea, a key alternative route, accounts for up to 30 percent of global container trade, and its security is also in question due to threats from Iran-allied Houthi militants.
The US naval operation involves more than a dozen warships patrolling east of the strait in the Gulf of Oman, enforcing a blockade on all vessels entering or leaving Iranian ports. The stated goal is to halt Iran's sea trade completely while encouraging non-Iranian ships to resume passage through the critical waterway.
According to maritime data company Kpler, several vessels with links to Iran appeared to make U-turns or slow down after the blockade was implemented. The last time the US and Iran engaged in similar naval escalations in 2019, insurance premiums for tankers in the region surged by as much as 1,000 percent. A sustained blockade could trigger a similar spike in costs, ultimately affecting consumers through higher energy and goods prices.
The Strait of Hormuz is the world's most important oil chokepoint. Before the conflict, it saw more than 120 vessels transit daily, carrying one-fifth of global oil and gas. The International Energy Agency has previously called a blockage of the strait the “largest disruption in history” to oil supply.
While the immediate impact on container rates has been muted, the potential for a wider conflict keeps markets on edge. The S&P 500 has recovered from its initial sell-off on hopes of a peace deal, but the blockade introduces a new source of volatility. A prolonged standoff could force a re-evaluation of risk, with potential impacts on global equity markets, inflation, and operational costs for industries reliant on maritime trade.
