BREAKING: Iran Cuts Gas Flow to Türkiye After South Pars Strike, Hitting Regional Supply

By Bosphorus News Energy Desk

Iran has cut natural gas exports to Türkiye following last week’s strike on the South Pars gas field, according to Bloomberg, bringing the impact of the conflict directly into Türkiye’s supply system as regional energy flows remain disrupted.

Bloomberg reported that the halt followed Israel’s 18 March attack on South Pars, citing people familiar with the matter. The development links physical damage at Iran’s most important gas field to pipeline deliveries into Türkiye at a time when Gulf energy routes are already under strain.

South Pars sits at the core of Iran’s energy system. The field accounts for the majority of the country’s gas production and supports electricity generation, heating and industrial use. Damage there has immediate domestic consequences and limits Iran’s ability to sustain exports.

The cutoff lands in a market already tightened by wider disruption. The conflict has hit energy infrastructure across the Gulf, while the closure of the Strait of Hormuz has reduced LNG availability and increased price volatility. Under those conditions, any loss of pipeline gas adds pressure on regional supply balances.

For Türkiye, the interruption raises immediate questions around replacement and system balancing. The country continues to import gas from Russia and Azerbaijan and maintains LNG capacity, but Iranian pipeline flows remain part of its supply mix. A prolonged halt would increase exposure to higher spot prices and constrain flexibility.

The development also reinforces the importance of the Southern Gas Corridor. Carrying Azerbaijani gas through Georgia and Türkiye into Europe, the corridor has gained weight as one of the few overland routes supplying non-Russian gas to European Union markets. Any disruption on Türkiye’s eastern supply side increases the strategic value of volumes still moving west.

Bloomberg said the duration of the stoppage is not yet clear. That uncertainty is likely to keep attention on whether Iran can stabilise output after the South Pars strike and how quickly Türkiye can offset any sustained shortfall.

Turkish media reports on 24 March echoed the Bloomberg account, pointing to the South Pars strike as the trigger for the cutoff and highlighting the risk to supply planning if flows do not resume.
