$10 Billion Four Seas Energy Corridor to Bypass Strait of Hormuz
The New Lines Institute proposes a $10 billion “Four Seas” energy corridor to bypass the Strait of Hormuz. According to Oilprice.com, the plan would link the Persian Gulf, Mediterranean, Black, and Caspian Seas via Syria and Turkey, transporting up to 4 million barrels of oil daily and 50 billion cubic meters of natural gas annually to Europe.
Why bypass the Strait of Hormuz?
Persistent tensions between the United States and Iran have made the Strait of Hormuz a geopolitical chokepoint. The New Lines Institute (NLI) argues that diversifying export routes is essential to reduce the risk of supply disruptions. By moving energy overland, the “Four Seas” initiative aims to lower Europe’s reliance on Russian and Iranian energy sources.
The strategy shifts the flow of energy away from vulnerable maritime lanes. This move would redirect investment from Persian Gulf states toward Western-oriented infrastructure projects, securing a more stable pipeline to European markets.
How would the “Four Seas” infrastructure work?
The NLI plan outlines a land-based network connecting the Persian Gulf to the Mediterranean through Iraq and Jordan. From there, the corridor extends into Syria and Turkey, creating central distribution hubs for energy moving toward the Black and Caspian Seas.

This network wouldn’t just move oil. The proposal includes the mobilization of $10 billion to build the necessary gas pipelines. The goal is to create a seamless transit system that connects multiple maritime basins, effectively turning the Levant region into a continental energy bridge.
What is the economic impact for Syria and Turkey?
The initiative views the stabilization of Syria following the Assad regime as a critical window for transformation. NLI reports that a post-Assad Syria could generate between $8 billion and $12 billion in annual combined revenue through energy production and transit fees.

Turkey would similarly benefit by cementing its role as a primary energy hub. By hosting these pipelines, Turkey increases its leverage over European energy security and strengthens its economic ties with Gulf investors.
How does this compare to the Three Seas Initiative?
The “Four Seas” model is based on the existing Three Seas Initiative (3SI). While the 3SI focuses on 13 European Union member states to improve north-south connectivity in energy and digital infrastructure since 2015, the “Four Seas” plan expands this logic to a transcontinental scale.
| Feature | Three Seas Initiative (3SI) | Four Seas Initiative |
|---|---|---|
| Focus | EU connectivity (North-South) | Gulf-to-Europe transit |
| Primary Goal | Infrastructure & Digitalization | Energy diversification/Bypassing Hormuz |
| Key Regions | Baltic, Adriatic, Black Seas | Persian, Med, Black, Caspian Seas |
Frequently Asked Questions
Who is funding the Four Seas initiative?
The plan calls for the creation of a consortium to mobilize up to $10 billion, primarily targeting investments from Persian Gulf states.
Which countries are central to this route?
According to the New Lines Institute, the route relies on Iraq, Jordan, Syria, and Turkey to move energy from the Gulf to the Mediterranean and beyond.
How much energy would this corridor move?
The proposal targets a capacity of 4 million barrels of oil per day and 50 billion cubic meters of natural gas annually.
