China instructs some major refiners to maintain high fuel production to protect domestic supplies, according to people familiar with the matter cited by Bloomberg. The move comes as renewed tensions involving Iran raise concerns that oil shipments through the Persian Gulf could be disrupted again. Bloomberg reports that China’s guidance is aimed at ensuring enough fuel is available for consumers at home despite potential disruptions in crude or product flows tied to the region. The reporting notes the latest concern stems from strikes in the Persian Gulf that have, at times, threatened shipping routes and the broader energy supply chain. The instruction targets refiners involved in meeting China’s demand, and it emphasizes sustaining output rather than cutting production in response to supply uncertainty. The Investing.com item also frames the decision as China directing refiners to keep fuel output high because the Iran conflict poses a risk to supply. No additional policy details or specific production targets are provided in the excerpts.
