Iraq-Turkiye Pipeline: Flows Halted Again Ahead of July 2026 Deadline

The Iraq-Turkiye pipeline (ITP) has halted crude oil flows again as of early March 2026, with approximately 200,000 barrels per day (bpd) shut in after producers reduced output as a precautionary measure. The stoppage comes with a critical deadline looming: Turkey formally terminated the legal agreements governing the pipeline in July 2025, with that termination taking effect on 27 July 2026. Baghdad and Ankara have less than five months to negotiate a replacement framework or risk the permanent closure of a pipeline that has moved northern Iraqi crude to Mediterranean markets for over five decades.

Pipeline Status: From Restart to Halt in Six Months

The ITP resumed flows on 27 September 2025 after a two-and-a-half-year shutdown triggered by a 2023 arbitration ruling that ordered Turkey to pay Iraq $1.4 billion in compensation for facilitating unauthorised Kurdish oil exports. The restart followed a US-facilitated trilateral deal between Baghdad, the Kurdistan Regional Government (KRG), and international oil companies operating in the Kurdistan Region, with Iraq’s State Organisation for Marketing of Oil (SOMO) taking full control of sales.

Initial flows at restart reached approximately 200,000 bpd, well below the pipeline’s combined nameplate capacity of 1.5 million bpd across its twin 40-inch and 46-inch lines running 960 kilometres from Kirkuk to the Ceyhan terminal on Turkey’s Mediterranean coast. The trilateral export agreement was extended to March 2026 — and flows have now ceased again as that arrangement has lapsed without a permanent successor deal in place.

Turkey’s Treaty Termination: What It Means

Turkey’s termination of the Iraq-Turkey Crude Oil Pipeline Agreements — originally signed in 1973 and last amended in 2010 — was announced by presidential decree in July 2025 and takes effect on 27 July 2026. The termination covers the original 1973 agreement and all subsequent protocols, memoranda, and amendments that have governed pipeline operation for over five decades.

Ankara’s stated motivation is dissatisfaction with pipeline utilisation and a desire to renegotiate on broader terms. Turkey wants any new agreement to cover gas transit, electricity interconnection, and new financial terms — not simply oil transit . Turkey also has not paid the $1.4 billion arbitration award and is believed to be seeking a settlement of that liability as part of any renegotiation. The July 2026 deadline creates a forcing mechanism — but it also creates the risk that talks fail and the pipeline enters legal limbo with no governing framework.

Iraq’s Strategic Exposure

For Baghdad, the ITP is not simply a commercial route — it is a sovereign export diversification asset. Iraq’s primary export infrastructure runs through the southern Basra terminal and the Strait of Hormuz, a route exposed to periodic threat from regional tensions. The northern Ceyhan route offers an alternative path to Mediterranean and European buyers that bypasses the Gulf entirely.

The treaty governing the ITP was originally signed in 1973, last renewed in 2010, and expires in July 2026 — and Ankara has informed Baghdad of its wish not to renew the agreement. With SOMO now in control of all northern export sales following the trilateral arrangement, Iraq has more leverage than at any previous point in the pipeline’s recent history — but that leverage is time-limited. The KRG’s exposure is equally significant: the 2023 shutdown cost the federal government, the KRG, and oil companies an estimated $25 billion in lost revenues over its duration.

Ceyhan Terminal: Capacity Sitting Idle

The Ceyhan terminal on Turkey’s southern coast is one of the Mediterranean’s largest crude export hubs, handling volumes from both the ITP and the Baku-Tbilisi-Ceyhan (BTC) pipeline connecting Azerbaijan’s Caspian fields to the Mediterranean. BTC volumes — primarily Azeri Light crude — continue to flow regardless of the ITP’s status, but the terminal’s infrastructure was designed for combined throughput significantly above current utilisation.

Turkey’s BOTAS pipeline operator constructed a spur connecting domestic Gabar oilfields to the ITP system, briefly feeding Turkish crude into the line during the ITP’s shutdown period — a move that Baghdad characterised as a violation of the bilateral agreements. That episode underscores Ankara’s interest in repurposing pipeline capacity for its own production, adding another dimension to the renegotiation dynamic.

Outlook: Negotiation Window Closes in July 2026

The March 2026 flow halt puts renewed pressure on Baghdad and Ankara to reach a framework agreement before the July deadline. Turkish officials have proposed expanding bilateral energy cooperation to cover gas transit and electricity — aligning the ITP’s future with the broader Development Road infrastructure corridor that Turkey is promoting as a trade route linking Basra to European markets via Turkish territory.

For Iraq, accepting a broader energy package may be the price of securing a new pipeline agreement. For Turkey, the termination notice was as much a negotiating tactic as a strategic withdrawal. Whether the two sides can close a deal in the available window — against a backdrop of unresolved arbitration liability, KRG sovereignty disputes, and competing infrastructure proposals — remains the critical question for northern Iraq’s oil export future.
