Ukraine says it is prepared to enter a maritime truce covering safe commercial navigation in the Black Sea, endorsing proposals put forward by Egypt, India and Türkiye as attacks on merchant ships and ports intensify. President Volodymyr Zelenskyy told leaders at the UN on September 23 that Kyiv was ready to ensure safe shipping and food security if Russia takes reciprocal de-escalation steps. Russia has not accepted the proposal; Foreign Minister Sergei Lavrov said separately that Moscow opposed a temporary pause in the wider fighting, although U.S. Secretary of State Marco Rubio said both Russia and Ukraine had expressed interest in a more limited arrangement involving grain and energy targets. Türkiye reinforced the maritime push on September 24, with President Recep Tayyip Erdoğan calling attacks by both sides on commercial vessels unacceptable and urging action on Black Sea navigational safety.
Black Sea Truce Watch · September 2026
Kyiv Says Yes. The Operational Deal Does Not Exist Yet.
Ukraine has publicly accepted the concept of a Black Sea maritime truce, but the detailed rules, monitoring system, geographic scope and Russian participation still have to be established before shipowners can treat the basin differently.
Ukraine
Ready
Zelenskyy says Ukraine is prepared to support safe shipping and food
security if Russia takes reciprocal de-escalation steps.
→
Proposals
Egypt · India · Türkiye
Kyiv says all three countries have presented ideas for restoring safe
merchant navigation in the Black Sea.
→
Russia
No Acceptance Yet
Moscow has not publicly accepted the maritime proposal and Lavrov has
rejected the idea of a temporary pause in the broader fighting.
→
Shipping
Still High Risk
Commercial vessels remain exposed to attacks, higher war-risk costs
and uncertainty around port access and voyage planning.
Kyiv's Core Position
Safe Shipping + Food Security
Zelenskyy said Ukraine was waiting for a Russian response and was
prepared to support safe Black Sea shipping if Moscow also moved
toward de-escalation.
The Commercial Baseline
Insurance
Entire Basin High Risk
London's Joint War Committee expanded Black Sea reporting
requirements across the full basin in September.
Voyage Cost
+$100Ks
Reuters reports war-risk premiums adding hundreds of thousands
of dollars to some seven-day voyages.
Merchant Casualty
Captain Killed
A Tanzania-flagged vessel heading toward a Ukrainian port was
attacked on September 17.
Russian Grain
Routes Shifting
Russian exporters are already redirecting grain toward Baltic
and Arctic ports after Black Sea disruption.
Türkiye Plan
Safe Grain Passage
Ankara says it has submitted a plan and is talking with both sides.
U.S. Signal
Limited Truce Interest
Rubio says both sides have expressed interest in arrangements involving grain and energy.
Public Terms
Incomplete
Monitoring, enforcement, ports and military-vessel rules have not been publicly defined.
Current Status
Proposal Stage
No bilateral Black Sea ceasefire has been announced or put into force.
Important distinction:
Ukraine's declaration is an acceptance of a proposed maritime truce framework.
It is not an announcement that Black Sea hostilities have stopped, and there is
not yet a jointly published Russia-Ukraine operating agreement.
Merchant Ships · Ports · Grain · Insurance · Verification
A Truce Headline Is Only Step One
For commercial operators, the decisive questions are operational: which ships are protected, whether ports are included, who verifies attacks and what happens when one side alleges a violation.

| Issue | What Is Publicly Known | Ukraine | Russia | Commercial Requirement | Still Undefined |
|---|---|---|---|---|---|
| CORE ISSUE Merchant Vessels | The current proposals are explicitly tied to safe commercial navigation and food-security shipping. | Kyiv says it is prepared to participate if Russia takes real reciprocal de-escalation steps. | No public Russian acceptance of the new maritime proposal has been announced. | Clear protection for neutral-flagged merchant ships regardless of cargo origin or destination. | Vessel eligibility, prohibited cargoes, inspection rights and whether Russia-linked sanctioned vessels are covered. |
| NOT CLEAR Ports & Terminals | Public statements focus primarily on shipping and grain movement. | Ukraine wants safe access to commercial export infrastructure. | Russian strikes have continued against Ukrainian port and logistics infrastructure while Ukraine has targeted Russian export infrastructure. | A vessel cannot use a protected corridor effectively if its loading terminal, anchorage or approach channel remains exposed to attack. | Whether the truce would explicitly protect Odesa, Chornomorsk, Pivdennyi, Novorossiysk and other commercial ports. |
| HIGHLY SENSITIVE Military Activity | The current public proposal does not contain detailed rules governing naval vessels or military drones. | Kyiv has used long-range and maritime drones against Russian military, energy and shipping-related targets. | Moscow continues missile and drone attacks against Ukrainian targets and has rejected a broader temporary cessation. | Commercial operators need physical separation between protected merchant routes and active military operations. | Exclusion zones, naval patrol rules, drone operations and rights of self-defense. |
| MEDIATION FOCUS Grain & Food Cargoes | Türkiye's submitted plan specifically addresses safe grain passage, while Zelenskyy links the wider truce to food security. | Ukraine depends heavily on Black Sea outlets for agricultural exports. | Russia also depends heavily on Black Sea grain exports and is now rerouting some volumes through Baltic and Arctic ports. | Reliable port calls, predictable voyage schedules and enough confidence for charterers and insurers to commit ships. | Whether any accord would include Russian demands related to food, fertilizer, banking or sanctions. |
| MARKET RESPONSE War-Risk Insurance | The entire Black Sea now falls under expanded Joint War Committee reporting requirements. | A functioning agreement could reduce the physical risk affecting Ukraine-bound voyages. | Russian-port voyages face a separate combination of war, sanctions and compliance exposure. | Underwriters need a sustained reduction in attacks rather than a political announcement alone. | How quickly premiums would decline and whether the whole basin would eventually be removed from heightened-risk treatment. |
| CRITICAL GAP Monitoring & Enforcement | No monitoring system has yet been announced for the current proposals. | Ukraine has said outside countries can play a role in maritime de-escalation. | Moscow has historically sought guarantees covering its own trade interests when discussing Black Sea agreements. | Owners need a contact point for incidents, verification and rapid clarification of alleged violations. | Whether Türkiye, the UN, the U.S. or another group would operate a coordination and verification mechanism. |

Black Sea Deal History
July 2022
Grain Initiative
Türkiye and the UN broker a safe-shipping mechanism that ultimately
moves almost 33 million tonnes of Ukrainian grain.
July 2023
Russia Withdraws
Moscow leaves the grain agreement, arguing obstacles remain for
Russian food and fertilizer trade.
March 2025
Safe-Navigation Framework
Washington separately announces that Russia and Ukraine agreed in
principle to safe navigation and elimination of force in the Black Sea.
Summer 2026
Attacks Escalate
Both sides intensify attacks affecting commercial vessels, ports
and export infrastructure.
Sep. 23–24
New Truce Push
Ukraine publicly says it is ready; Türkiye presses both sides to
stop attacks on merchant shipping.
The March 2025 precedent matters.
The White House announced separate commitments from Kyiv and Moscow to safe
navigation and eliminating force in the Black Sea, but Russia subsequently
tied implementation to relief affecting its agricultural trade. Current
commercial attacks demonstrate that no durable maritime cessation resulted.

Scenario model only:
a maritime truce would not automatically remove the Black Sea from war-risk
listings or eliminate sanctions, compliance, mine, crew-safety or security
costs. Insurance pricing would depend on actual attack frequency, duration
of compliance and underwriter assessment after an agreement takes effect.
