UK activates worst-case Cobra planning for CO2 and food shortages tied to Hormuz closure past June
British officials disclosed the Cabinet Office Briefing Room A (Cobra) has run
Analysis
Exercise Turnstone's disclosure, corroborated by IBTimes UK and GB News after The National's initial readout, which carries privileged Gulf-sourced access to UK planning, is the first Whitehall confirmation that Hormuz has crossed into domestic-resilience territory, and the operative risk is CO2, not food: an 82% supply collapse hits meat-sector stunning immediately, transfusion services within weeks, and civil-nuclear cooling within 60-90 days. Prior reporting treated Hormuz closure effects as macroeconomic; Cobra's named cascade thresholds give those risks institutional ownership for the first time. Emergency-legislation drafting before the scenario materializes is very unusual and likely signals that within the coming month Treasury has moved its assessment of Hormuz remaining closed past June above the 30-35% probability range. The quieter tell is the UK's apparent readiness to unwind climate-adjacent industrial policy to preserve chemical-sector CO2 output, a reversal that costs months of policy capital and is not undertaken speculatively.
