Commercial shipping through the Strait of Hormuz has declined due to security concerns and soaring insurance premiums for tankers.

This downturn threatens the stability of global energy markets, as approximately one-fifth of the world’s oil passes through the narrow waterway between Oman and Iran [1].

In a recent discussion, Pramit Pal Chaudhuri, India Practice Head at Eurasia Group, and Christof Ruehl, Global Adviser at Crystol Energy, analyzed the strategic dynamics of the region. They said that oil markets may be under-pricing the current risk despite the volatility. The decline in traffic is attributed largely to the deterrent effect of high insurance costs and persistent security worries.

These tensions follow a period of direct conflict, including a joint U.S.-Israel attack on Iran that began on Feb. 27, 2024 [2]. While a cease-fire was announced for Aug. 17, 2024 [3], the lasting impact on maritime logistics remains significant.

The stability of the region currently hinges on a memorandum of understanding between the U.S. and Iran. However, experts said the terms of this agreement remain vague. Specifically, the document lacks clear definitions regarding "Iranian arrangements," leaving the strategic balance uncertain.

Control of the waterway remains a point of contention. Some reports indicate Iran still maintains control of the Strait, while other accounts emphasize the challenges posed by U.S. and Israeli military interventions [1], [2]. This ambiguity contributes to the hesitation of commercial shipping firms to return to pre-conflict volumes.

“Commercial shipping through the Strait of Hormuz has declined.”

The combination of high insurance premiums and ambiguous diplomatic agreements suggests that the formal cease-fire has not yet translated into commercial confidence. Because the U.S.-Iran memorandum lacks specific operational definitions, shipping companies are treating the Strait of Hormuz as a high-risk zone, potentially leading to long-term shifts in oil transport routes or sustained price volatility.
