Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

What changed

Dated, newest first

  1. Chapters 17, 18, 19 provisionally closed 12 Oct 2026; 21 of 33 closed; all 33 opened; Kos: the finish line is within reach; Spajić goal of membership in 2028 [1]
  2. Council figures: 21 of 33 chapters provisionally closed, all 33 opened; nothing final until an overall agreement [4]
  3. Croatia withholds consent on chapter 14 and holds up chapters on foreign and security policy, judiciary and fundamental rights, justice freedom and security; demands on war crimes, missing persons, property, maritime boundary, school ship Jadran; elections due June 2027; Kos: Montenegro could still join by 2028 without closing every chapter in 2026 [2]

Why it matters

Montenegro is the front-runner for EU membership: it has opened all 33 chapters and provisionally closed 21. The Commission says the finish line is within reach and the prime minister aims for membership in 2028. Croatia is holding up four chapters over bilateral claims, and Montenegro votes in June 2027.

Why Likelihood 5 Sources on each side: the Commission and government aim to close (21 of 33 closed, 2028 goal) vs Croatia holding four chapters with no deal. Pushes: Croatia's hold; elections in June 2027. Brakes: eight chapters closed in 2026 so far. An open contest.

The other facts on file (1)
  • Government: 20 chapters remained to close in 2026 [3] (16 Dec 2025)

How it spreads

If

By 31 Oct 2027, at least one of Montenegro's 33 opened negotiating chapters is still not provisionally closed (judged on that date).

Not under way

Channels 3 on the card

  1. CanadaNo Canadian loss sourced.
  2. Accession treatyClosing every chapter is the step before the accession treaty; a slip delays entry (Strature's view).
  3. The regionA bilateral veto that holds would signal that neighbours can stall the last stage for Albania and others (Strature's view).

Three scenarios and their signposts

  1. S1

    Deal and close

    Croatia and Montenegro settle the claims and the last chapters close in 2027.

  2. S2

    Election pause

    Closure stalls around the June 2027 vote.

  3. S3

    Veto holds

    Croatia keeps the four chapters blocked through the window.

The signposts of each scenario
PathSignpost
S1A foreign ministries' agreement
S2No intergovernmental conference in the first half of 2027
S3Chapter 14 still open after the next conference

No probability is given for the three paths.

The other side

A settlement with Croatia would clear the last political block on the front-runner and could speed Albania's path too (Strature's view) [1][2].
