Iran has issued a warning that oil and gas infrastructure across the Persian Gulf could become "legitimate targets" in response to an Israeli strike on its South Pars gas field. This escalation raises the risk of direct attacks on facilities in Qatar, Saudi Arabia, and the United Arab Emirates, widening the conflict beyond Iran's borders and threatening key hydrocarbon-producing regions.

Impact on Critical Infrastructure and Global Supply

The South Pars field is one of the world's largest natural gas developments and a cornerstone of global LNG supply, shared between Iran and Qatar. The warning signals a potential shift from the earlier sparing of Gulf energy infrastructure, now raising the risk to upstream facilities, processing hubs, and export terminals. Regional energy flows are already under severe strain due to major disruptions to shipping through the Strait of Hormuz, a chokepoint for roughly one-fifth of global oil and gas supply. This has forced production shut-ins among Gulf producers and tightened global supply, causing crude prices like Brent to surge above $108 per barrel.

Expanding Conflict and Market Risks

Iran has intensified regional attacks using drones and missiles, targeting both military and energy-linked assets in countries like the UAE and Saudi Arabia. Despite this escalation, some Iranian export operations, such as crude loadings at Kharg Island, have continued under constrained conditions. Analysts identify the greatest market risk as broader disruption to critical global infrastructure nodes, including:

• Saudi Arabia's Abqaiq processing facility
• The UAE's Fujairah export hub
• Qatar's LNG infrastructure

Sustained damage to these facilities could trigger significant production losses and further tighten markets.

Long-Term Market Focus

As the conflict continues, the focus for energy markets is shifting from short-term price volatility to the longer-term risk of supply disruption. This is particularly pertinent if attacks expand to include major upstream or export infrastructure across the Gulf.
