On November 13, 2026, Türkiye and Qatar signed a mutual defense agreement in Istanbul as Greece defended continuing seabed surveys in the Eastern Mediterranean and a Kyrenia court examined missing recordings from the Filo Jet disaster.
The treaty's military assistance terms remain unpublished. A separate dispute over a research vessel off Cyprus also emerged as Turkish and Greek warships took part in the same NATO exercise.
Gulf Defense | Türkiye and Qatar Sign Pact as Mecca Approval Process Continues
President Recep Tayyip Erdoğan and Qatar's Emir Sheikh Tamim bin Hamad Al Thani met in Istanbul on November 13 for the 12th Türkiye-Qatar Supreme Strategic Committee meeting. They signed a Mutual Defense Agreement, and their governments declared a common position against an external armed attack on either or both countries. The communiqué also covers security consultations, joint exercises, military training and defense industry cooperation.
The communiqué leaves the authorization of military assistance, possible deployments and the treaty's entry into force unexplained. Türkiye already maintains troops in Qatar under earlier bilateral arrangements. Their presence does not establish what the new agreement would require in a future crisis.
The Istanbul signature follows two agreements with different legal purposes. Türkiye, Pakistan and Saudi Arabia signed the Mecca Agreement for Joint Defense on August 7. On November 5, the Turkish parliament adopted the law approving its ratification. The vote did not itself complete the treaty's international entry-into-force procedure.
Türkiye, Qatar, Pakistan and Indonesia also signed the Badr Memorandum on October 21. The Turkish-Qatari communiqué welcomed that initiative, which concerns defense industry cooperation, production, technology and supply chains. Badr does not carry the same defense commitments as the other two agreements. Nor do the three instruments establish a single four-country military alliance.
Energy and regional diplomacy also featured in the Istanbul talks. Erdoğan and the emir called for expanded liquefied natural gas trade and unrestricted navigation through the Strait of Hormuz. The joint statement also addressed Gaza, Lebanon, Syria, Yemen, Sudan, Somalia, Libya and Cyprus. No new operational arrangements were announced for those theaters.
Aegean and Eastern Mediterranean | GSI Surveys, Rival NAVTEX and NATO Activity
At Iraq's Slemani Strategic Forum on November 13, Greek Foreign Minister Giorgos Gerapetritis said Greece would not accept interference with surveys for the Great Sea Interconnector (GSI), the planned electricity cable between Greece and the Republic of Cyprus. He maintained that Greece had authorized the work. He discussed GSI alongside the proposed Greece-Egypt electricity connection, the Vertical Gas Corridor and the India-Middle East-Europe Economic Corridor. No new financing or agreements were announced for those projects.
His remarks followed a radio exchange on November 12 south of Karpathos. The Turkish frigate TCG Gökova asserted Ankara's consent claim to the French-flagged survey vessel Abeille Marengo; the Greek frigate Limnos answered that Greece had authorized the work. Greek and Republic of Cyprus reports said the vessel kept surveying without being physically stopped. The French diplomatic notification and opposing naval messages remain central to the dispute. Neither France's note nor Ankara's written reply has been published.
A separate research dispute surfaced later on November 13. Antalya NAVTEX station's warning 1136/26 challenged Larnaca warning 347/26 concerning Bob the Shark, a vessel scheduled to conduct visual and acoustic marine-mammal surveys around Cyprus from November 12 to 26. Türkiye argued that the notified area crossed waters it claims and waters under Turkish Cypriot authority, without coordination with its institutions. No physical action against Bob the Shark was reported. Its marine-mammal research is separate from the GSI seabed survey, although both have prompted competing jurisdictional claims.
Off Aksaz, Turkish naval forces held the distinguished visitors' day of Mavi Balina-2026, an anti-submarine exercise scheduled for November 9-20. Navy Commander Adm. Ercüment Tatlıoğlu reported eight submarines, 20 surface units, ten aircraft and approximately 4,500 personnel. Greek and Spanish ships participated through Standing NATO Maritime Group 2, a North Atlantic Treaty Organization (NATO) formation. Tatlıoğlu also said the third Reis-class submarine, Muratreis, was expected to enter service later in November; commissioning had not yet taken place.
That NATO operation followed its own command arrangements. It did not change either government's position on research consent near Karpathos.
Cyprus and the EU | UN Talks, Crossings and Defense Spending
Turkish Cypriot President Tufan Erhürman said on November 13 that rotating leadership and at least one affirmative Turkish Cypriot vote in federal decisions remained central to his negotiating approach. He said he had consulted Türkiye and proposed an informal meeting with Republic of Cyprus President Nikos Christodoulides at the 31st United Nations climate conference (COP31), which did not take place because of scheduling. Erhürman's new proposal has not been made public.
In Dublin, Christodoulides said he expected a meeting with Erhürman and United Nations Secretary-General António Guterres to be arranged after Guterres's travels. He wants discussions on confidence-building measures and a date for a wider conference. Neither a meeting date nor a negotiating mandate had been announced by November 13. Christodoulides also announced that the next Greece-Republic of Cyprus intergovernmental summit was planned for November 18.
The November 9 understanding on simultaneously opening Akıncılar/Louroujina-Limya/Lympia and Kambo/Kampos-Gemikonağı/Karavostasi has yet to yield an opening date. Ministers in the Turkish Cypriot government have objected to the presidency's conduct of the talks, particularly where road access, staffing and other implementing decisions fall to the cabinet. The disagreement over Erhürman's negotiating role and the cabinet's responsibilities has yet to be resolved.
The Republic of Cyprus presented its proposed 2027 defense budget to parliament on November 13. Defense Minister Vasilis Palmas outlined €894.7 million in spending, an increase of €266.6 million over 2026. The draft earmarks €430.15 million for defense capabilities, compared with about €177 million the previous year, including procurement under the European Union's Security Action for Europe (SAFE) framework. Palmas also identified local defense manufacturing as a priority. These remain proposed budget allocations; they do not represent completed purchases or deliveries.
In a separate EU process, a Council decision was published on November 13. Council Decision 2026/2557, adopted on November 9, sets out the Union's position on technical rules for implementing the existing EU-Türkiye Customs Union, including customs documentation. The decision neither opens modernization talks nor approves the political incentives reportedly under discussion ahead of European Commission Executive Vice-President Raffaele Fitto's planned November 20 visit to Ankara.
Maritime Safety | Missing Filo Jet Recordings and the Mersin Complaint
Police told a Kyrenia court on November 13 that their examination of Filo Jet's voyage data recorder (VDR) was complete, confirming that no records were available for August 30, when the catamaran sank shortly after leaving Kyrenia for Taşucu. Officer Mehmet Mannaş also reported recording gaps on other dates. The court extended the detention of nine suspects, including the captain and his deputy, for seven days at their 12th appearance. Defense lawyers questioned the handling of the investigation but did not oppose the detention extension.
The absence of recordings from the day of the sinking was already disclosed at an October 9 hearing. On November 13, police said the specialist examination was complete and identified two further gaps: July 31-August 5 and August 8-16. The device had also failed to log equipment faults. Earlier hearings had identified an interruption in bridge audio on August 28, a separate finding that should not be confused with the newly detailed recording gaps. Investigators are still seeking the ship's Safety Management System Manual and emergency-duty assignments, and are examining evidence gathered in Türkiye. The cause of the gaps and the sinking has not been established.
Survivors and victims' families filed a criminal complaint with the Mersin Chief Public Prosecutor's Office on November 4. As detailed in Bosphorus News's examination of the Turkish parliamentary record, Türkiye's Transport Ministry confirmed three port-state inspections, time-limited approvals for services to Türkiye and a June 2 survey by Türk Loydu on behalf of the Turkish Cypriot flag administration. The ministry disclosed the dates, but not the inspection findings or any deficiencies identified.
The Kyrenia proceedings concern the sinking and the conduct of people under investigation there. In Mersin, the families have asked prosecutors to examine business connections, maintenance and regulatory oversight involving Türkiye. The inspection history and missing recordings establish no individual's criminal responsibility. The unreleased survey reports, maintenance files and recorder history could clarify what was known about the vessel before its final voyage.
COP31 | Climate, Energy & Finance
The Asian Infrastructure Investment Bank (AIIB) released the terms of two loans to Türk Eximbank totaling $300 million: $100 million for green infrastructure and sustainable energy, and $200 million to support exporters facing external shocks. Both were included in the four-bank, $5.1 billion financing package signed on November 12. They must not be added to that total.
QNB Türkiye announced a separate framework for up to $500 million in financing over five years with the Asian Development Bank, AIIB, European Bank for Reconstruction and Development (EBRD), Dutch development bank FMO and the World Bank Group's International Finance Corporation. Proposed uses include green and social financing and nature-related investments. Disbursements under those arrangements have not been confirmed.
The European Investment Bank and İller Bankası signed a November 13 agreement to help municipalities prepare climate-resilient and lower-carbon projects. The agreement provides technical assistance, with no new loan announced. At the EBRD's COP31 events, Türkiye's Industrial Decarbonisation Investment Platform presented low-carbon pathways for glass and ceramics, adding project-development work in two more sectors to its existing industrial agenda.
The Organization of Turkic States held the first ministerial meeting of its Partnership for Climate, Innovation, Green Economy and Trade in Antalya. Officials discussed the Turkic Investment Fund, digital commerce and green finance, without announcing a new binding funding commitment. A separate clean-energy partnership among Türkiye, Azerbaijan, Georgia and Bulgaria had been signed on November 10. Its proposed cross-border transmission projects still need financing and delivery arrangements.
At Akkuyu, eight days of strength and leak-tightness tests on the first reactor's inner containment were completed, according to World Nuclear News. Cold and hot functional tests are among the next commissioning steps, the operator said. Energy Minister Alparslan Bayraktar said at a COP31 nuclear event that physical start-up was expected in the coming weeks. The reactor has not yet begun generating power. He also advocated the COP31 Presidency's global target of raising electricity's share of final energy demand to 35% by 2035.
Türkiye's nuclear supplier talks continued on another track. Under an agreement signed on November 12, Türkiye Nükleer Enerji Anonim Şirketi and Canada's Candu Energy will study feasibility and front-end engineering for a possible plant at Sinop. AtkinsRéalis executives have discussed a six-reactor option totaling 4.5 gigawatts, against Ankara's earlier plan for four reactors at that site. The CANDU feasibility work and financing discussions have not settled the design, unit count, ownership or investment decision.
UN climate officials also pressed for affordable access to financing. The existing goals of $300 billion a year by 2035 under developed-country leadership and $1.3 trillion a year from all funding sources were discussed. No new target was adopted on November 13.
Middle East and Maritime Energy | Hormuz and the Iraq-Syria Oil Route
Iran's Islamic Revolutionary Guard Corps Navy claimed on November 13 that two oil tankers had struck mines in the Strait of Hormuz and caught fire. Iranian authorities separately alleged that a liquefied natural gas carrier hit a mine while using an unauthorized route, Reuters reported. Vessel identities and technical evidence of the reported mine strikes were not independently confirmed. Maritime authorities had recorded other shipping incidents in the area earlier in the week.
With Hormuz disrupted, Iraqi crude has begun moving by road to the Mediterranean. Reuters reported that Qatar-based UCC Holding started trucking heavy oil on October 26 from the Tuba storage site near Basra to Syria's port of Baniyas. Iraqi officials described shipments of approximately 120,000-150,000 barrels a day, subject to truck availability, and about 1.6 million barrels loaded for Mediterranean markets including Türkiye, Greece and Italy. The route's capacity depends on truck availability, transit conditions and transport costs.
Saudi Arabia has also shifted more oil toward its Yanbu export terminal. Unlike Iraq's truck route, the Yanbu option uses a pipeline. No evidence links UCC Holding's shipments to the Türkiye-Qatar defense agreement signed on November 13.
Türkiye Markets | Fund Repayments, Returns and SPK Action
Türkiye's tenth Fund Coordination Board meeting, chaired by Vice President Cevdet Yılmaz, reported that payments across 119 funds had reached approximately 161 billion Turkish lira by November 13. According to the Presidency's Directorate of Communications, 444,893 investors had received cash or in-kind distributions and 333,493 had recovered their full net investment. The figures cover cumulative payments in ordinary and extraordinary liquidations, not a new distribution made during the meeting.
Türkiye Sigorta disclosed a voluntary payment of 1,599,887,908 lira to the Savings Deposit Insurance Fund (TMSF), representing inflation-adjusted gains connected to funds in liquidation. The company maintained that its original investments complied with the applicable rules. The Capital Markets Board (SPK) meanwhile introduced disclosure, general-meeting and financial-reporting requirements for certain voluntary returns under Law No. 7596.
SPK's November 13 bulletin also called for criminal complaints against 65 individuals over share trading in E-Data Teknoloji, Kardemir Çelik and Graintürk Holding, and imposed trading restrictions on specified individuals and companies. Those stock-trading cases cannot all be attributed to the extraordinary fund liquidation. Criminal complaints do not establish guilt.
Earlier arrests had already brought the wider fund investigation into the banking regulator and financial institutions, including a deputy chairman of the Banking Regulation and Supervision Agency (BDDK) and a bank chief executive. Separately, MSCI's November index changes and its concerns about Turkish market accessibility remain relevant to overseas investors. MSCI has not linked its index changes to the latest SPK actions. Likewise, the 161 billion lira in investor payments and voluntary returns to TMSF cannot be added as separate compensation totals; they belong to overlapping recovery and liquidation processes.
Bosphorus Read
Türkiye's Gulf defense agreements now offer three different tests of commitment. The Mecca treaty has a documented parliamentary approval stage; Badr concerns defense industry cooperation; the Qatar treaty's public communiqué speaks of a common response to attack. The missing Qatar text matters because Türkiye already has troops on the ground. Under what authority would either government request assistance, and would an existing deployment fall under the new arrangement? Until the authorization and command provisions are known, treating these instruments as one military alliance would assign them obligations that the available documents do not establish.
The GSI encounter shows the limits of what can be inferred from an operation that continues without obstruction. The French survey ship kept working after the radio exchange; Ankara and Athens kept their opposing claims. The separate Bob the Shark warning extends the argument over consent to scientific research unrelated to a power cable. Meanwhile, Greek and Turkish crews can operate under the same NATO exercise command. That provides a channel for military cooperation, but the public record does not establish which procedures would govern a more serious encounter around a survey vessel. The ability to exchange radio messages is not, by itself, a tested mechanism for handling an escort, a course change or physical interference.
The proposed Cyprus crossings expose an obstacle that a diplomatic meeting cannot resolve on its own. Erhürman can reach an understanding with Christodoulides, but the road works, staffing, budgets and property arrangements will require action by institutions whose ministers are contesting his approach. The European Union faces a different division of authority: technical changes to the existing Customs Union can proceed without Brussels having approved modernization negotiations or the industrial concessions mentioned in diplomatic reporting. Any incentive meant to advance Cyprus talks would need a clear approval route, agreed conditions and institutions able to deliver it. None has yet been presented as a binding package.
COP31 has moved some projects closer to implementation without settling their commercial viability. The AIIB loans have identified borrowers, whereas QNB still needs financing transactions and municipalities must prepare investable projects. Grid access, permits and disbursement conditions will determine what actually gets built. Nuclear decisions require a different test: Akkuyu's containment checks move one reactor toward commissioning, while the Canadian study has yet to establish a viable Sinop contract. Ownership and fuel obligations, rather than the technology label, will determine how far Türkiye can diversify its nuclear dependence.
Iraq's road route to Baniyas is a measurable response to disrupted Gulf shipping, but its future rests on truck capacity, transit security and delivered cost. Those constraints may keep it commercially useful without making it a substitute for seaborne exports. UCC Holding's Qatari ownership provides no evidence of coordination with the new defense treaty. Claims of mine strikes in Hormuz require named ships and technical findings before their effect on shipping can be assessed.
The new SPK disclosure requirements offer a way to test whether voluntary repayments can be traced to identifiable transactions and properly reflected in company accounts. They cannot determine criminal responsibility, which belongs to a separate process. Investor distributions measure restitution; MSCI's concerns center on market transparency and accessibility. The durability of Türkiye's market recovery will depend on what regulators and issuers disclose about ownership, trading and enforcement, not simply on the volume of money repaid.
