Renewed hostilities in the Middle East are keeping supply disruption concerns firmly on the table, pushing European natural gas benchmarks toward a fourth consecutive weekly advance as winter fuel inventories face mounting pressure. Despite choppy trading on Friday, the benchmark contract is still up more than 7% for the week.

After a relatively calm stretch, the escalating exchange of military strikes between the United States and Iran has driven natural gas prices across Europe and Asia to their highest levels in over three years in recent sessions. Before the conflict erupted, roughly one-fifth of the world's oil and liquefied natural gas passed through the Strait of Hormuz from the Middle East to global markets.

While some crude tankers are still managing to transit the crucial waterway, LNG exports from Qatar through the Strait of Hormuz have largely ground to a halt. With the heating season fast approaching, Europe is facing significant pressure to replenish its gas reserves. Storage facilities across the continent are only about 66% full, marking the lowest level for this time of year on record.

Germany's situation is even more severe, with storage inventories sitting at just 54%. Meanwhile, the United Arab Emirates continues to load LNG vessels in the Persian Gulf despite the regional instability, though overall shipping traffic remains well below pre-conflict levels. Strategists Warren Patterson and Eva Manthey at ING noted in their report this week that "the escalation in the Persian Gulf has dashed hopes for a recovery in LNG exports from the region."

With winter approaching, competition for gas supplies between Europe and Asia could intensify, "particularly if Qatari LNG remains largely absent from the market through the end of the year."
