Turkey halts Turkmenistan gas imports via Iran under US pressure

Turkey stopped importing Turkmenistan’s gas through Iran. The arrangement began in March 2025 and was designed to deliver 1.3 billion cubic metres annually to Turkey. It mattered because it gave Ankara access to Turkmen gas without waiting for a new direct pipeline from Turkmenistan across the Caspian Sea.

Iran served as the transit route. Turkmen gas entered Iranian infrastructure, crossed the country, and then reached Turkey. Turkish importer Botas held an import licence for the arrangement until 2033. Turkey said it was not paying Iran, but Iranian involvement still became a problem under US sanctions rules.

The flow stopped after US-Iran tensions escalated. Turkmenistan had already cut supplies in October 2025, citing the short-term contract and unresolved volume and price terms. Although Turkey later said imports would resume, they did not. The arrangement therefore remains suspended.

OFAC is the US Office of Foreign Assets Control. It administers and enforces US economic sanctions. Those sanctions can restrict transactions, services, financial channels, or business involving sanctioned countries, companies, or infrastructure. The article identifies OFAC as the reason Turkey stopped the Turkmen gas arrangement.

The key mechanism is indirect exposure. Gas could come from Turkmenistan, and Turkey said it was not paying Iran, but the shipment still depended on Iranian infrastructure. When the situation between Iran and the United States escalated, companies and governments faced sanctions-related risks connected with that route. Those risks can make an otherwise workable energy deal impossible to continue.

Turkey’s Energy Minister Alparslan Bayraktar said OFAC was somehow involved. He linked the stoppage to the US-Iran war, which the article says began in February. The case shows that sanctions can affect transport arrangements, not only direct payments.

The deal promised Turkey 1.3 billion cubic metres of Turkmen gas each year. That volume is important, but it is not enough to transform Turkey’s entire gas supply. It would provide an additional source and reduce reliance on other suppliers, especially during periods of strong demand or disrupted deliveries.

For scale, 1.3 billion cubic metres is roughly 2–3% of Turkey’s overall annual gas use, using recent consumption levels as a comparison. The article itself gives the deal’s volume but not Turkey’s total consumption, so this percentage is an outside estimate rather than an article figure.

The volume could matter more strategically than its percentage suggests. Turkey has spare capacity in the Trans-Anatolian Gas Pipeline, and Bayraktar said exports to Europe could potentially double. Turkmenistan’s abundant reserves could therefore support both Turkey and European buyers if transport barriers are overcome.

For Turkey, the immediate consequence is the loss of a planned annual gas source. The suspended arrangement would have supplied 1.3 billion cubic metres from Turkmenistan. That does not represent Turkey’s whole energy system, but it would have added supply diversity and potentially reduced pressure on other import arrangements.

Europe could also lose a possible future supply route. Turkey is positioned between gas-producing countries and European markets, and Bayraktar said the Trans-Anatolian Gas Pipeline has spare capacity. He said Turkey could easily double the volume of gas exported to Europe, but the halted Turkmen arrangement means that potential supply is not currently moving through this route.

The longer-term effect depends on whether the route can restart and whether Turkmen gas reaches Turkey by another path. Turkey’s gas contracts with Iran expire in November, and it remains unclear whether Ankara will renew them. Azerbaijan’s reserves are also slowly being depleted, increasing interest in Turkmenistan’s gas.

Routing more Turkmen gas through Azerbaijan and Turkey offers a way to connect Turkmenistan’s abundant reserves with two markets: Turkey and Europe. It could also help address the article’s warning that Azerbaijan’s gas reserves are slowly being depleted. Turkey already has the Trans-Anatolian Gas Pipeline, which Bayraktar says has spare capacity.

The main obstacle is getting gas from Turkmenistan to Azerbaijan. A pipeline would need to cross the Caspian Sea, but a dispute over exclusive economic zones makes that infrastructure harder to build. Without a new connection, Turkmenistan cannot easily send larger volumes westward through Azerbaijan and onward to Turkey.

The route is therefore attractive but not ready to replace the halted Iranian transit arrangement. Turkey could potentially double gas exports to Europe, according to Bayraktar, yet the necessary Turkmen-Azerbaijani link remains constrained by infrastructure and legal disputes. The outcome depends on resolving those barriers.

Turkey is both a gas buyer and a transit country. It wanted Turkmen gas for its own market and could use spare Trans-Anatolian capacity to send more gas toward Europe. Turkmenistan supplies the gas and has abundant reserves, but its October cut showed that contract terms on volumes and prices also matter.

Iran provided the infrastructure needed for the original route. The United States affected that route through OFAC and broader sanctions pressure after tensions with Iran escalated. Azerbaijan is a possible bridge for Turkmen gas, although its own reserves are slowly being depleted and a Caspian pipeline faces disputes over exclusive economic zones.

European gas buyers are potential customers for increased exports through Turkey. Their interest aligns with Turkey’s plan to expand exports, but the article does not identify individual buyers or specific contracts. The suspended route and unresolved infrastructure problems leave all parties without a settled long-term arrangement.

Natural gas needs a physical route, a contract, and permission for the route to operate. Pipelines carry gas across borders, while transit agreements set terms such as volumes, prices, licences, and responsibilities. If any part fails, gas may stop even when the producer and buyer still want the trade.

The Turkmen arrangement shows this interaction clearly. Turkmenistan’s gas used Iranian infrastructure to reach Turkey. Botas had an import licence until 2033, but the arrangement also depended on agreed volumes and prices. Turkmenistan said in October 2025 that it could not sell gas without agreement on those terms. Later, US sanctions pressure created another barrier because Iran was involved in the route.

The current result is a suspended flow. Turkey’s possible alternatives require more infrastructure, including a connection between Turkmenistan and Azerbaijan. That option faces Caspian economic-zone disputes. Legal, commercial, and physical conditions must therefore align before gas can move reliably.
