Montenegro had opened the accession track, built negotiating institutions and accepted the logic of chapter-by-chapter conditionality, but it had not yet reached the decisive phase where closure, budget integration and treaty preparation become the core issues. Its central conclusion was cautious: Montenegro wanted EU membership, but still lacked the full institutional capacity and compliance record required for accession.
Five years later, that diagnosis has not become irrelevant. It has changed scale. Montenegro is no longer merely trying to demonstrate that it understands the negotiation framework. It is now being tested on whether it can complete the remaining chapters, absorb the financial and administrative consequences of membership, and prove that reforms are durable enough for the EU to admit a new member without creating new rule-of-law or governance risks inside the Union.
This is the real shift in Montenegro’s accession story. The country has moved from the technical opening of chapters to the political economy of closing them. The European Commission and the Council now record that Montenegro has opened all 33 negotiating chapters, with 16 provisionally closed after the June 2026 accession conference, which closed Chapter 2: Freedom of movement for workers and Chapter 28: Consumer and health protection. That places Montenegro ahead of other Western Balkan candidates in formal negotiation progress, but it also means that the remaining chapters are now more politically sensitive and institutionally demanding.
The 2021 paper was built around the logic of EU conditionality. It examined Montenegro’s negotiating context, the institutions involved, the role of lobbying and the way European Commission reports translated the accession process into points of agreement and disagreement. That method remains useful because the EU accession process is not a single political bargain. It is a structured audit of state capacity. Each chapter tests whether Montenegro can legislate, implement, enforce and monitor EU-compatible rules across markets, courts, public administration, agriculture, environment, energy, taxation, customs, financial control and fundamental rights.
The difference now is that the audit is reaching its hardest stage. Opening chapters is evidence of alignment ambition. Closing chapters is evidence of implementation credibility. The EU’s negotiating principles also make clear that provisional closure is not final until an overall accession agreement is reached. That means Montenegro’s 16 closed chapters are important, but they are not irreversible political capital. The remaining chapters, especially those linked to rule of law, judiciary, fundamental rights, justice, freedom and security, will determine whether the country’s accession timetable remains credible.
The old chapter-based analysis therefore needs to be updated with a new financial and institutional layer. In June 2026, the European Commission presented a dedicated financial package for Montenegro’s possible accession under the next Multiannual Financial Framework 2028–2034. The indicative package totals €3.189 billion over 2028–2034, including €2.076 billion under Heading 1 for cohesion, agriculture, rural and maritime prosperity and security, €523 million under competitiveness, prosperity and security, €147 million under Global Europe-related adjustment and €442 million for administration.
That changes the meaning of the accession chapters. They are no longer only legal files to be negotiated in Brussels. They are becoming gateways to actual EU budget flows, investment pipelines and administrative obligations. Chapter 33: Financial and budgetary provisions, once a technical budget chapter, now matters directly for the state’s fiscal planning. Chapter 22: Regional policy and coordination of structural instruments becomes central to whether Montenegro can absorb cohesion-style funding. Chapter 11: Agriculture and rural development, already provisionally closed, becomes connected to the proposed €277 million Common Agricultural Policy envelope. Home affairs, linked to borders, migration and internal security, becomes tied to a proposed €592 million allocation because Montenegro’s accession would create a new EU external border.
This is why Montenegro’s accession process has moved into an engineering phase. The country must not only pass legislation; it must build systems. It needs paying-agency capacity for agriculture, audit systems for EU funds, procurement controls, border infrastructure, digital customs, environmental enforcement, judicial performance, energy-market alignment, statistical reliability and anti-corruption track records. These are not abstract European standards. They are the operating conditions for receiving and managing EU money without disruption or correction.
The 2021 paper’s emphasis on institutions is therefore still highly relevant. Montenegro’s accession depends less on declarations of European orientation and more on whether institutions can perform under pressure. A small administration can be an advantage because coordination is easier, but it can also be a weakness because absorption capacity, technical staffing and project preparation are limited. EU membership would multiply the administrative burden. Ministries, municipalities, regulators, courts, inspection bodies, paying agencies and public enterprises would all face higher scrutiny.
The political dimension is equally important. Montenegro’s formal progress is strong, but EU accession today is shaped by lessons from previous enlargements. Brussels is more concerned about post-accession backsliding, rule-of-law durability and the credibility of safeguards. The EU’s decision to begin work on drafting an accession treaty for Montenegro in 2026 is a major milestone, but it also reflects a more cautious enlargement environment in which treaty safeguards and value-protection mechanisms are likely to be stronger than in earlier rounds.
For Montenegro, this creates a dual opportunity. The first is symbolic and geopolitical: becoming the EU’s next member would anchor the country firmly inside the European institutional system and strengthen its position in the Western Balkans. The second is economic: accession would open a larger funding and investment framework, improve credibility with lenders, support regional development and help diversify an economy still too dependent on tourism, real estate and public spending.
But the risks are also clear. Montenegro could enter the final stage of negotiations with strong headline progress while still facing bottlenecks in implementation. The chapters that remain open are not equal in difficulty. Some are technical and can move quickly if legislation and administrative systems are in place. Others require a record of enforcement, court decisions, convictions, transparent procurement, media freedom protection, environmental compliance and credible institutional independence. These cannot be created overnight.
That is why the negotiation process should now be read through three linked tests. The first is legal alignment: whether Montenegro can complete the remaining acquis obligations. The second is institutional delivery: whether adopted laws are enforced by functioning bodies. The third is financial absorption: whether Montenegro can turn potential EU funding into completed projects, measurable reforms and sustainable public investment.
The academic paper framed Montenegro’s accession as a chapter-based negotiation between a candidate country seeking membership and a Union setting mandatory requirements. That remains true, but the 2026 context is sharper. Montenegro is now close enough to accession for the EU to estimate its budget cost, prepare financial transition mechanisms and start the accession treaty process. The accession chapters are no longer a distant roadmap. They are becoming the checklist for Montenegro’s first years inside the Union.
The country’s advantage is that it has a clear lead in the Western Balkan accession race. Its challenge is that the final stretch is not about speed alone. It is about credibility. A country can close chapters quickly only if it has already built the institutions that make closure defensible. Montenegro’s task is to show that its reform record can survive the pressure of membership, EU funding, domestic politics and external scrutiny.
The 2021 paper captured Montenegro at a stage when the question was whether it met the conditions for EU membership. The 2026 reality is more advanced but more demanding: Montenegro is now being asked to prove that it can function as a member state from day one. The next phase of accession will be decided not by the number of chapters opened, but by the quality of the state machinery behind the remaining closures.
