Suez Canal Tolls and Turkey’s £20bn Canal Plan: 5 Strategic Shifts
The suez canal is back at the center of a bigger argument about power, risk and revenue. As tensions around the Strait of Hormuz rise, Turkey’s £20 billion Istanbul Canal is attracting attention because it would create a toll-based route that looks less like a national infrastructure project and more like a strategic bet on global shipping. The appeal is simple: if natural chokepoints become more volatile, artificial waterways that can charge fees may look increasingly valuable. That is the economic logic now shaping the debate.
Why the Suez Canal Model Matters Now
The new attention is not only about Turkey. It is also about what the suez canal represents: a man-made route that can monetize transit traffic. The Istanbul Canal, planned to run parallel to the Bosphorus Strait, is described as a route linking the Black Sea and the Sea of Marmara and capable of handling around 160 vessels or oil tankers each year.
That design matters because natural straits are treated differently under the United Nations Convention on the Law of the Sea. Ships have the right of transit passage through straits used for international navigation, while bordering states generally cannot demand payment for passage. Man-made waterways, by contrast, can levy tolls. That distinction is the core reason the suez canal remains such a powerful reference point in this debate.
What Lies Beneath the Istanbul Canal Push
Turkey’s proposal is tied to economics as much as geopolitics. The project is estimated at £20 billion, with £12 billion for the canal itself and £8 billion for development on either side, and it is expected to be completed by 2027. In 2021, President Recep Tayyip Erdogan called it transformative for Turkey’s economy and said it was intended to protect Istanbul’s Bosphorus and the citizens around it.
Yet the deeper attraction is revenue. The plan would allow Turkey to potentially monetize transit traffic in a manner similar to Egypt’s suez canal and Panama’s interoceanic route. That matters at a time when toll-based waterways are gaining credibility as stable income sources in a world where strategic routes can become political flashpoints.
Egypt’s own numbers underline why. Canal revenues reached $449 million between January 1 and February 8, 2026, with 1, 315 ships transiting the route, up from $368 million during the same period last year. The canal generated about $40 billion between 2019 and 2024 and remains Egypt’s most important source of foreign currency. The Suez Canal Authority forecasts roughly $8 billion in the 2026/2027 fiscal year, rising to about $10 billion the following year.
Expert Perspectives on Law, Fees and Risk
Legal limits are central to the debate. The United Nations Convention on the Law of the Sea allows transit passage in international straits, but it does not give bordering states a free hand to impose fees. That is why Turkey’s canal proposal is being watched so closely: as an artificial waterway, it would open the door to structured tolls without breaching international law.
The broader political test is whether strategic waterways can be turned into revenue engines without triggering legal or diplomatic pushback. The issue is now being sharpened by Iran’s demands in its standoff with Washington, which has brought the question of charging vessels in strategic waterways into a much more sensitive phase. In that sense, the suez canal is no longer only an Egyptian asset; it is a template others are trying to adapt.
Regional and Global Impact
The regional implications extend beyond Turkey and Egypt. Rising tensions around the Strait of Hormuz have heightened demand for alternative maritime chokepoints, increasing attention on projects that can offer control, predictability and revenue. For energy markets and shipping operators, the immediate concern is not just cost but continuity. A managed canal route may look attractive when existing routes appear exposed to geopolitical shocks.
At the same time, the comparison is revealing. The suez canal is profitable because it is a controlled passage through which states can charge for access. If Turkey succeeds in turning the Istanbul Canal into a similar model, it would show how infrastructure, law and geopolitics are converging around one simple idea: control the route, and you can shape the trade.
The unresolved question is whether more states will now treat the suez canal model as a blueprint for the next generation of strategic waterways, or whether legal and political limits will keep that ambition in check.
