Shipping operations across the Strait of Hormuz and the Bab al‑Mandeb Strait have faced severe disruption over the past 48 hours, as fresh attacks, military escalation, and covert vessel movements deepen instability across two of the world’s most critical maritime corridors.
In the Strait of Hormuz, tensions spiked following reports that Iran struck an oil tanker accused of unauthorized transit, underscoring Tehran’s increasingly assertive posture over the waterway. This comes amid broader threats by Iranian forces warning that vessels could be targeted if they fail to comply with evolving security directives.
Shipping data over the last two days highlights the immediate operational fallout. Vessel traffic through Hormuz has dropped sharply, with only three to four commercial ships transiting daily - well below recent averages.
Several tankers have reportedly switched off tracking systems or adopted indirect “dark routes” to avoid detection, while others have delayed entry altogether.

Meanwhile, activity in the Bab al-Mandeb Strait - linking the Red Sea to the Gulf of Aden - remains under sustained pressure from Iran-backed Houthi forces.
Although transit volumes there have not collapsed to the same extent, crossings have still declined below average levels, reflecting heightened risk perceptions among operators.
The Houthis’ continued targeting of Saudi-linked shipping and their growing control over Yemen’s Red Sea coastline are compounding the threat environment.
The dual disruption across both chokepoints is forcing significant adjustments in regional logistics. Saudi Arabia, for instance, has been compelled to continue routing oil exports through Hormuz despite efforts to bypass it, as alternative corridors via the Red Sea face parallel security risks.
This has driven up freight rates, insurance premiums and transit complexity.
Wider supply chain impacts are also emerging. Cargo volumes across the Gulf have dropped dramatically in recent days, with some estimates indicating a near-total collapse in container traffic through Hormuz-linked routes.
Traders and shipowners are increasingly diverting cargo, splitting shipments, or relying on smaller regional ports, adding cost and delays.
With military activity intensifying and no clear de-escalation in sight, both the Strait of Hormuz and Bab al-Mandeb are entering a period of sustained operational volatility - raising fresh concerns over global energy flows and maritime security in the days ahead.
