Market resolves to YES if the UK government implements the originally announced full ban on imports of Russian oil products (including diesel and jet fuel routed via third countries) in full before 1 September 2026. In May 2026 ministers said the ban would be phased in rather than applied immediately due to fuel supply concerns linked to the Iran conflict. Partial restrictions, guidance changes, or further delays resolve NO. Resolution is based on published UK statutory instruments or official government implementation notices.
