ed miliband vows permanent shutdown of the north sea

The permanent ban on new North Sea oil and gas fields creates a regulatory supply constraint for UK upstream production. This reduces future domestic output, increasing reliance on imports (LNG, pipeline gas) and potentially raising wholesale gas prices for UK utilities and consumers. The channel is regulatory (supply restriction) with a global oil crisis context. Direct losers: UK upstream producers (e.g., Shell, BP, smaller operators). Winners: LNG importers, renewable energy developers. Impact is UK-specific but with global oil price spillover due to the Iran war.
