Why a 90-Year-Old Treaty Limits NATO in the Black Sea

The Forgotten Treaty That Keeps the Black Sea a Military Vacuum
The 90-year-old Montreux Convention, signed on July 20, 1936, has had a lasting impact on the balance of power in the Black Sea. Despite its age, the treaty’s influence remains significant as Ukraine struggles against Russia’s invasion. NATO’s inability to project power into these vital waters raises questions about the limitations imposed by an outdated agreement.
The Black Sea has become a critical security front line since 2022, with warships from various nations patrolling its surface. Yet, paradoxically, it remains largely empty of warships. This is largely due to the Montreux Convention’s strict rules governing access to the Turkish Straits, which connect the Black Sea to the Mediterranean.
A Single Path Forward
The convention’s key provision allows free passage for civilian ships during peacetime but restricts military vessels, imposing a 21-day limit on their stay in the sea. This arrangement keeps Turkey in a powerful position as gatekeeper of the straits, giving it significant influence over regional trade and security. As Daria Isachenko, a visiting fellow at the German Institute for International and Security Affairs, notes, “Turkey’s sovereignty over the Turkish Straits is essential to its status as a major power.”
The Shadow of History
The Montreux Convention was born out of the ashes of World War I, when international oversight of the Ottoman Empire’s vital waterways became necessary. Its 30-page document established the framework governing the Turkish Straits, with Turkey regaining control over these strategic passageways. This treaty has been repeatedly tested by war and conflict, including in 2022, when Russia invaded Ukraine.
A Test of Will and Steel
When Russia launched its full-scale invasion, the Montreux Convention faced one of its greatest challenges since its inception. Article 19 was invoked, restricting military ships belonging to countries engaged in the fight from passing through the straits. This decision had far-reaching consequences, preventing Russia from adding more vessels to its Black Sea fleet and giving Ukraine a temporary advantage.
The Limits of Technology
The conflict has highlighted how warfare itself has evolved, with Ukraine leveraging drones and modern technology not covered by the 1936 document. “Ukraine didn’t build military vessels; it just shifted the generation of attack,” notes Iulian Chifu, a Romanian foreign policy analyst. This underscores the limitations imposed by treaties like the Montreux Convention, which struggle to keep pace with rapidly changing technologies.
The Price of Neutrality
Turkey’s approach to the conflict has been calculated and deliberate. By restricting NATO’s access to the Black Sea, it sends a clear message: “Leave us alone in the Black Sea, we will handle this.” This stance not only reflects Turkey’s own interests but also underscores its commitment to neutrality in the face of great power rivalries.
The Future of the Montreux Convention
As tensions continue to simmer in the region, the Montreux Convention remains a crucial factor. Its enduring relevance lies in its long-standing recognition by states and its ability to adapt to changing circumstances. However, its limitations are also evident – particularly in its inability to account for modern technologies or the evolving nature of warfare.

The Montreux Convention's stranglehold on NATO's naval presence in the Black Sea is a relic of a bygone era, but its implications for regional security are very much alive. While Turkey's sovereignty over the Turkish Straits is undeniably a cornerstone of stability, one cannot help but wonder if this arrangement has simply shifted the balance of power from one imperial overlord to another – namely, Russia. As the conflict in Ukraine drags on, it's clear that an update to this 90-year-old treaty is long overdue, lest we witness a repeat of history's darker chapters.

The Montreux Convention's restrictive rules on military access have become a convenient excuse for NATO's inaction in the Black Sea. However, what's often overlooked is that Turkey's leverage over the straits has also made it a key player in regional diplomacy. Ankara's willingness to balance its relationships with Russia and Ukraine has allowed it to maintain some semblance of stability in the region. As the conflict escalates, it's crucial for NATO to reassess its strategy and find ways to work around – or through – Turkey's gatekeeping role.

The Montreux Convention's hold on NATO's Black Sea presence is more than just a relic of history – it's a strategic straitjacket. While the article correctly identifies the treaty's limitations on military vessels, it overlooks the fact that these restrictions also apply to NATO ships. This dichotomy raises questions about the alliance's flexibility and willingness to adapt to modern security threats. Can NATO truly counter Russia in the Black Sea if its own actions are constrained by a 90-year-old agreement? The answer is unclear, but one thing is certain: this outdated treaty demands a serious reevaluation.
