A survey indicates that many shipping companies intend to keep using oil or explore nuclear power for their vessels after the Hormuz Strait crisis highlighted shipping's vulnerability to chokepoint disruptions. The continued reliance on fossil fuels exposes global oil supply chains to geopolitical shocks and delays decarbonization of maritime transport, affecting energy markets and climate goals. Shipping companies surveyed, Iran (via Hormuz crisis), United States (through its Hormuz leverage plan), and regulators such as the IMO. Firms may await clearer geopolitical stability before investing in alternative fuels; the US could bolster naval presence or promote routing alternatives to secure Hormuz; IMO may tighten emissions rules pushing eventual fuel shifts. A survey released amid heightened Hormuz Strait tensions shows many maritime companies intend to continue relying on fossil fuels, with some considering nuclear power as an alternative. The finding underscores the sector's sensitivity to chokepoint risks and the slow pace of fuel transition even when security threats are evident. Likely next events: Possible IMO revisions to greenhouse gas strategy for shipping Increased US naval or diplomatic activity to secure the Strait of Hormuz Follow‑up surveys on adoption of low‑carbon fuels in the fleet Sectors affected: Maritime shipping Oil and gas Nuclear energy Regulatory implications: IMO 2023 greenhouse gas strategy revisions Potential sanctions or restrictions on Iranian oil exports Safety or security mandates for chokepoint transits Historical parallels: 1973 oil crisis prompting shipping route changes 2011‑2012 Iran sanctions reducing tanker traffic through Hormuz 2021 Suez Canal blockage showing global trade's chokepoint fragility
