The Israeli strike on Iran’s South Pars gas field on 18 March 2026, represents one of the most consequential escalations in the ongoing Iran-Israel conflict, as the first direct strike on critical energy infrastructure, and will have global economic significance. The South Pars field, which Iran shares with Qatar’s North Dome field, is the largest natural gas reservoir in the world and forms the backbone of Iran’s domestic energy system. It also underpins a substantial share of global Liquefied Natural Gas (LNG) supply through Qatari exports.

Any disruption to this field therefore carries implications far beyond Iran itself. Reports indicate that the Israeli strike hit facilities in the Asaluyeh energy complex on Iran’s southern coast, including gas processing units, pipelines, and associated petrochemical infrastructure linked to South Pars production, resulting in temporary suspension of operations in parts of the field. Estimates suggest that roughly twelve per cent of Iran’s gas output was affected, a level of damage sufficient to disrupt domestic supply chains and force Tehran to halt gas exports to Iraq. The immediate market reaction reflected the strategic importance of the target, with oil prices rising sharply amid fears of wider disruption to Gulf energy flows.

By targeting energy infrastructure rather than purely military facilities, Israel signalled a willingness to impose costs on the Iranian state and population, and to expand the scope of the conflict into the economic domain.
