From the Hormuz Crisis to the Global Energy Architecture: A Geopolitical and Strategic Analysis of the Basra–Ceyhan Pipeline

The Anatomy of Vulnerability: The Strategic Imperative Stretching from Hormuz to Ceyhan

The proposal for the Basra–Ceyhan pipeline, put forward by Fatih Birol, Executive Director of the International Energy Agency (IEA), in April 2026, should be viewed not as a sudden political reflex, but as the product of decades of structural vulnerability. Whilst the temporary reopening of the Strait of Hormuz provides short-term relief, the point Birol emphasised is crystal clear: the risk of this strait closing has now become a permanent fixture in global energy calculations. This observation goes beyond the foresight of any single leader or institution; it serves as a confirmation that a phenomenon discussed in energy security literature for decades has now reached its most critical historical turning point.

When the scale of this geographical bottleneck constricting global energy trade is laid out in data, a strikingly vivid picture emerges. According to IEA data, approximately 15 million barrels of crude oil passed through the Strait of Hormuz daily in 2025; this figure accounts for thirty-four per cent of global crude oil trade. When total oil and products are included for the same period, this figure rises to over 20 million barrels, constituting twenty-seven per cent of global seaborne oil trade on its own. Furthermore, 90 per cent of Qatar’s exports—the world’s second-largest liquefied natural gas (LNG) exporter—pass through this strait, making approximately 20 per cent of LNG trade dependent on a single geographical point. These figures elevate the Strait of Hormuz to the position of the most critical energy chokepoint in human history; any disruption to this chokepoint has the capacity to directly affect not only commodity markets but also global supply chains, food security and inflation dynamics.

In this context, the strategic importance of the Basra–Ceyhan route, as highlighted by Birol, goes far beyond that of a mere infrastructure project. The proposal in question is a structural intervention that must be discussed within the context of the reconstruction of the global energy security architecture, and this article aims to examine this proposal from an analytical perspective, taking into account both its historical depth and the current geopolitical context.

Iraq’s Oil Economy and Export Dependency: A Structural Constraint

In order for the Basra–Ceyhan pipeline debate to be conducted on the right footing, it is first necessary to understand Iraq’s structural position within the energy economy. Iraq is the country with the second-highest crude oil production within OPEC after Saudi Arabia and ranks as the sixth-largest producer of total petroleum liquids globally. With proven crude oil reserves recorded at 145 billion barrels, Iraq holds 17 per cent of the Middle East’s proven reserves and approximately 8 per cent of global reserves. The vast majority of this immense reserve is located in the Basra basin in the south, with smaller quantities situated in the Diyala region east of Baghdad and the Kirkuk region in the north.

However, this wealth, combined with an extremely fragile export infrastructure, creates a serious security vulnerability. Oil export revenues account for over ninety-five per cent of the government’s income; consequently, any disruption to export routes could lead to a financial collapse capable of paralysing the country’s entire public sector. As of mid-2024, export capacity from the south remains at approximately 3.4 million barrels per day, and even this level cannot be fully utilised due to infrastructure bottlenecks. To increase this capacity, Iraq approved the Sealine 3 project in the cabinet in 2023; furthermore, with the commissioning of new compressor facilities, an increase in export capacity of 300,000 barrels per day is targeted. However, the physical inadequacies of the infrastructure continue to pose a serious obstacle to these objectives.

An even more critical aspect is Iraq’s export geography. Almost the entirety of the country’s southern exports is channelled via the Gulf of Basra towards the Strait of Hormuz. The historically operational northern route, namely the Kirkuk–Ceyhan Pipeline, has effectively ground to a halt following a ruling in March 2023 by the International Court of Arbitration, where the Iraqi central government filed a case resulting in Turkey being ordered to pay $1.5 billion in compensation for unauthorised exports. Although this pipeline resumed operations in September 2025, its initial daily capacity remains at 250,000 barrels. With a design capacity of 1.6 million barrels per day and a length of 970 kilometres connecting Kirkuk to Ceyhan, the pipeline’s actual usable capacity, taking technical wear and tear into account, is only around 300,000 barrels per day. Looking at this picture, it is clear that Iraq’s northern export capacity remains structurally inadequate and that the country’s excessive reliance on the Strait of Hormuz route has not been genuinely addressed.

The Structural Vulnerability of the Strait of Hormuz and the Persistence of Security Risks

Birol’s proposal is, at its core, based on a logic of risk transfer: if the risk associated with the Strait of Hormuz has become permanent, the only effective way to manage this risk is through the construction of alternative routes. To test the validity of this proposition, it suffices to examine the structural vulnerabilities of the Strait of Hormuz. The Strait is merely 33 kilometres wide between Iran and Oman and possesses a commercial transit corridor of just two nautical miles in each direction. This physical narrowness transforms this narrow waterway, through which hundreds of oil tankers are forced to pass every day, into a unique strategic weak point for global oil markets.

EIA data for the first quarter of 2025 reveals that 22 per cent of crude oil passing through the Strait of Hormuz belongs to Iraq, whilst Saudi Arabia holds the highest share at 37 per cent. Five countries—namely Saudi Arabia, Iraq, the UAE, Iran and Kuwait—account for ninety-three per cent of the flow through the Strait of Hormuz. This high concentration dramatically increases the speed and severity with which a disruption of political or military origin would reverberate through global energy markets via a domino effect. As Birol also emphasised, repairing the damage to refineries and LNG facilities in the region will take a long time; this situation will transform a potential supply disruption from an immediate crisis into a prolonged supply shock.

Moreover, the current geopolitical climate is making the management of this risk even more difficult. The fact that global crude oil production has effectively reached its capacity ceiling is largely eliminating flexibility on the supply side. As Birol also highlighted, under current conditions there are two short-term options: keeping the Strait of Hormuz open or releasing additional volumes from strategic reserves into the market. However, strategic reserves are limited and cannot serve as a permanent structural solution. Warnings that, should tensions persist by late May 2026, oil prices will rise sharply, serious supply shortages will emerge in refined products—particularly jet fuel and diesel—and fertiliser and petrochemical supply chains will be disrupted, underscore the scale of this structural vulnerability.

The Basra–Ceyhan Route: Historical Background and Integration into the Development Path

The concept of the Basra–Ceyhan pipeline is, in fact, not a unique vision when assessed within the historical continuity of Iraq–Turkey energy relations, but rather a logical extension based on the expansion of existing infrastructure towards the south. The agreement forming the basis of the Kirkuk–Ceyhan pipeline was signed in 1973, entered into force in 1975, and, having been expanded through various protocols, has formed the backbone of bilateral energy relations for half a century. Turkey announced on 21 July 2025 its decision to unilaterally withdraw from this agreement, stating that it would cease to be valid on 27 July 2026; instead, it aims to establish a new framework agreement with a much broader scope, encompassing not only crude oil but also natural gas, petrochemicals and electricity. Energy and Natural Resources Minister Alparslan Bayraktar emphasised that, although the Kirkuk–Ceyhan pipeline was designed with a capacity of 1.5 million barrels per day, this level was never actually achieved, and clearly stated that mechanisms to ensure full capacity must be established in the new agreement.

A development that makes this historical context even more significant is Iraq’s 1,300-kilometre-long Development Corridor Project. This project, which will connect the largely completed Fav Port to the Turkish border, goes beyond road and rail transport to include new oil and natural gas pipelines stretching from Basra to Silopi. A Basra–Ceyhan pipeline integrated with the Development Corridor will transform Turkey from merely a transit country for crude oil into the hub of a multimodal energy backbone stretching from Basra to Europe. Should this vision be realised, Iraq will gain revenue stability by diversifying its export channels, whilst Turkey will have reinforced its geographical position with economic and political power.

Indeed, the recommissioning of the Kirkuk–Ceyhan pipeline in September 2025, with a capacity of 250,000 barrels per day, has further solidified the practical foundation of this strategic direction. The Iraqi Ministry of Oil’s statement in March 2026 also indicated that the northern pipeline is ready for exports as a countermeasure to disruptions on the southern route via the Strait of Hormuz, and this development concretises the sense of urgency regarding the expansion of the Basra route southwards.

Turkey’s Strategic Positioning: From Energy Corridor to Energy Hub Vision

Birol’s proposal identifies two distinct strategic opportunities for Turkey: the first is the repositioning of Istanbul as an alternative regional financial centre to Dubai; the second, and the decisive one, is the consolidation of the Ceyhan-centred energy corridor vision. Birol has clearly outlined the primary conditions for both opportunities: simplified tax structures, competitive financial incentives and sustainable macroeconomic stability; on the energy front, political consensus between Turkey and Iraq and the assurance of large-scale financing.

Turkey’s advantage in this equation is not limited to the transit revenue generated by its geographical location. Ceyhan’s current infrastructure capacity is sufficient to process Caspian oil from the Baku–Tbilisi–Ceyhan (BTC) pipeline; the introduction of a Basra–Ceyhan route would pave the way for these facilities to operate at much higher capacity and with significantly greater profitability. Furthermore, Turkey has consolidated its identity as a natural gas corridor through projects such as TurkStream and TANAP; in recent years, by constructing large-capacity LNG storage facilities, it has begun to assume the role of an energy bank serving both Europe and regional countries. The addition of crude oil from Basra to this picture has the potential to transform Turkey from merely a pipeline route into a genuine energy command centre where pricing, storage and re-export take place.

As Birol also emphasised, energy investment decisions are now shaped not only by cost and technology calculations, but also by the energy security risk premium. When assessed within this new framework, the number of countries willing to pay additional costs for a reliable and geopolitically stable route is increasing. With its geographical and infrastructural position capable of meeting precisely this demand, Turkey stands at a critical juncture to become an indispensable actor in the global energy security architecture.

The Value and Financial Dimension of the Project for Europe’s Energy Security

Birol’s indication that the project is open to European financing demonstrates that it is not merely a bilateral Turkey–Iraq issue, but rather a multi-dimensional initiative that must be included in the debate on the restructuring of the global energy security architecture. Following the outbreak of the Russia–Ukraine war, Europe has been forced to rapidly reduce its dependence on Russian energy sources and has accorded significant strategic priority to alternative supply routes. In this context, TANAP, which facilitates the transport of Caspian gas to Europe via Turkey, has become a pipeline operating at full capacity due to pressure on demand; it is assessed that a Basra–Ceyhan oil route could similarly meet Europe’s need for secure access to crude oil from the Middle East and the Gulf.

However, the scale and cost of this project should not be underestimated. According to IEA data for 2025, redirecting even a fraction of the daily exports exceeding 3 million barrels from the Strait of Hormuz to Iraq via the Ceyhan route would require investments amounting to billions of dollars. In terms of infrastructure financing, the participation of European public institutions (such as the European Investment Bank and the European Bank for Reconstruction and Development) and international energy companies could play a decisive role. However, the prerequisite for mobilising this financing is the establishment of a political framework of agreement between Turkey and Iraq, supported by comprehensive international legal safeguards and incorporating long-term purchase commitments.

In this context, the legacy of the legal disputes experienced throughout 2025 cannot be overlooked. The approximately two-and-a-half-year interruption of the Kirkuk–Ceyhan pipeline, spanning from March 2023 to September 2025, has had severe consequences not only economically but also geopolitically; it is estimated that Iraq lost approximately 25 billion dollars in revenue during that period. This experience clearly demonstrates the need for the legal foundations of any new mechanisms established in the future to be firmly grounded; it appears inevitable that dispute resolution mechanisms, revenue-sharing models and technical inspection protocols must be clearly defined in advance.

Conclusion: The Strategic Anatomy of an Opportunity

Birol’s Basra–Ceyhan proposal should be viewed not merely as a simple pipeline project, but as a crucial link in the transformation of the global energy security architecture in the post-Hormuz era. Iraq’s 145 billion barrels of proven reserves and its excessive dependence on the Strait of Hormuz; Turkey’s integration opportunity offered by its existing Ceyhan-centred corridor and the Development Corridor; Europe’s energy security demands, conditioned by its desire to become independent of Russian energy; and the legal infrastructure lessons left by international arbitration crises, transform this project into a structural opportunity—rarely seen in history—where different interest groups can all benefit simultaneously.

However, the realisation of this opportunity cannot be left to chance. As Birol also emphasised, once trust in the system is shaken, rebuilding it is extremely difficult. The most critical task facing Turkey and Iraq is not only to accelerate technical and financial preparatory work but also to swiftly implement a comprehensive framework agreement that will establish mutual trust, eliminate legal uncertainties, and ensure the project’s sustainability from both political and commercial perspectives. In this period when the global energy order is rapidly being reshaped, the strategic windows created by geographical and geopolitical conditions do not remain open for long. History reassesses the positions of nations based on whether such structural opportunities were seized in time.
