From Tehran Attacks Navigation Systems in Strait of Hormuz; Oil Flows Continue via STS

How could the attacks on navigation systems in the Strait of Hormuz affect Europe?

Possible What happens if… A possibility worth considering, not a forecast.

Europe's energy security faces risk from Strait of Hormuz instability The attacks by the Islamic Revolutionary Guard Corps and Tehran on navigation systems in the Strait of Hormuz introduce operational risk to Gulf oil exports. Gulf exporters are responding by increasing the use of ship-to-ship transfers (STS) off the coasts of Oman and the United Arab Emirates, utilizing locations near Sohar and Fujairah. While some sources suggested the attacks on Didamar island would have a limited impact on commercial shipping, the continued disruption and reliance on workarounds affect the stability of global oil flows, which is critical for Europe's energy security.

The facts so far

As reported. Each one links to where it comes from.

  • Iran attacked ship navigation systems on the Omani island of Didamar in the Strait of Hormuz.jpost.com
  • Gulf exporters have been increasingly using ship-to-ship transfers (STS) off the coast of Oman and the United Arab Emirates.jpost.com
  • Bigger tankers, mostly very large crude carriers (VLCCs), shuttle oil from Gulf ports to ship-to-ship transfer locations near Oman's Sohar and the UAE's Fujairah.jpost.com
  • Gulf oil exports recovered to over 80% of pre-war levels in September and October.jpost.com

Why it matters

The Strait of Hormuz is one of the world's most critical chokepoints for global energy trade. Any disruption, whether from military attacks or operational workarounds like STS, introduces uncertainty into the supply chain for oil and gas. For Europe, which relies heavily on imported energy, this instability translates directly into risks to its energy security and potential market volatility.

This incident occurs against a backdrop of ongoing geopolitical tension, where the US military has been aiding commercial vessels transiting the Strait since the US-Israeli war on Iran began in late February. The ability of Tehran to target infrastructure, as seen on Didamar island, demonstrates a capability that could further complicate maritime transit in the region.

What we don't know yet

  • Will the use of STS transfers increase the overall cost or complexity of Gulf oil transport?
  • How will the continued attacks on navigation systems affect the long-term viability of commercial shipping in the Strait of Hormuz?

What would change this answer

The attacks escalate or target major shipping lanes directly.The effect on Europe would become stronger and more immediate, potentially forcing major rerouting and supply shocks.
Gulf exporters successfully stabilize flows without relying on STS workarounds.The risk to European energy security would fade, as the primary operational vulnerability would be mitigated.
