ECB Insight: Rotation Risk in 2026, or Which Meetings Are Most Exposed to the Voting Roster

6 January 2026

By David Barwick – FRANKFURT (Econostream) – The European Central Bank emphasizes that the monthly rotation of Governing Council voting rights does not silence anyone: all governors still attend and have the right to speak, and most decisions are reached by consensus. A recent empirical study of the ECB’s rotation model is broadly consistent with that claim, finding only rare cases in which rotation appears likely to have determined outcomes.

Still, the identity of who is eligible to vote and who is not is not irrelevant. In the uncommon case of a genuinely knife-edge decision—one that is settled by a formal vote rather than the usual “mood-reading” in the room—who is entitled to cast a ballot can, by construction, matter at the margin.

And even when the rate decision itself is unchanged, the voting lineup can still influence how the ECB frames the balance of risks, the degree of optionality it signals and the tone of the policy outlook.

In this Insight, we abstract from the macro backdrop and ask a simple question: in 2026, which meeting outcomes have the greatest potential to be influenced by the rotation system, purely because of who does and does not hold a vote?

A tempting approach would be to apply Econostream’s hawk/dove scores to the six governors without a vote at each meeting and sum them. The problem is that this suggests a degree of precision that is misleading. The relevant institutional fact is one member, one vote—conditional, of course, on holding a voting right that month.

We therefore take a more straightforward approach and ask, for each meeting, whether rotation excludes more hawks, more doves, or an equal number of each. From there, it is naturally possible to note whether the excluded members are relatively hardline or moderate within their respective camps, but any meeting-specific “intensity” judgment depends heavily on the circumstances at the time.

None of this should be read as a mechanical forecast. By our taxonomy, hawks outnumber doves on the Governing Council overall, and among national central bank governors as well. Yet the Council is plainly able to take dovish decisions when warranted by the inflation outlook and the balance of risks. The exercise therefore identifies meetings where the voting roster could matter most in a genuinely close call, particularly for tone and risk framing.

The underlying distribution also cautions against simplistic “hawk majority” readings. Excluding Slovenia (whose acting governor has no vote), the average score across national central bank governors is very close to neutral.

And while the dovish camp is smaller, it is thus somewhat more pronounced on our scorecard than the hawkish camp. These are descriptive points, not predictions—but they reinforce that roster arithmetic should be treated as a marginal influence, not a deterministic driver.

Before getting into the details, a few assumptions are needed.

First, we assume that Slovenia, which currently lacks a permanent national central bank head, will soon have one, and that this person will tend to side with the hawks.

Second, we assume that Estonia’s incoming governor Ülo Kaasik, who will take over from current officeholder Madis Müller after Müller’s term ends on 6 June 2026, will, like Müller, turn out to be a policy hawk.

Third, we assume that Bank of Lithuania Governor Gediminas Šimkus, whose term ends on 6 April 2026, and Bank of Greece Governor Yannis Stournaras, whose term ends on 26 June 2026, will both be reappointed.

Finally, we ignore the very plausible possibility that a sitting governor will succeed ECB Vice President Luis de Guindos, whose term ends on 31 May 2026, and that the relevant national central bank will therefore itself need a new governor.

Here are the eight 2026 monetary policy meetings and the governors excluded from voting, classified as hawks or doves using our current hawk/dove taxonomy.

5 February 2026 (five hawks, one dove): Olaf Sleijpen, Pierre Wunsch, Dimitar Radev, Madis Müller, Gabriel Makhlouf; Olli Rehn.

19 March 2026 (five hawks, one dove): Joachim Nagel, Madis Müller, Gabriel Makhlouf, Boris Vujčić, Christodoulos Patsalides; Yannis Stournaras.

30 April 2026 (four hawks, two doves): José Luis Escrivá, Boris Vujčić, Christodoulos Patsalides, Gaston Reinesch; Mārtiņš Kazāks, Gediminas Šimkus.

11 June 2026 (three hawks, three doves): Martin Kocher, Slovenia, Peter Kažimír; Fabio Panetta, Álvaro Santos Pereira, Olli Rehn.

23 July 2026 (five hawks, one dove): Olaf Sleijpen, Pierre Wunsch, Dimitar Radev, Ülo Kaasik, Peter Kažimír; Olli Rehn.

10 September 2026 (three hawks, three doves): José Luis Escrivá, Boris Vujčić, Christodoulos Patsalides; Yannis Stournaras, Mārtiņš Kazāks, Gediminas Šimkus.

29 October 2026 (two hawks, four doves): Gaston Reinesch, Martin Kocher; François Villeroy de Galhau, Mārtiņš Kazāks, Gediminas Šimkus, Alexander Demarco.

17 December 2026 (five hawks, one dove): Olaf Sleijpen, Pierre Wunsch, Dimitar Radev, Slovenia, Peter Kažimír; Olli Rehn.

On this count-based view, February, March, July and December all tilt heavily dovish: five hawks lose votes in each case, while only one dove does.

April also tilts dovish, but less so.

June and September are close to neutral, with equal numbers of hawks and doves excluded.

October stands out as the only meeting at which the rotation system materially favors the hawks, with four doves excluded against only two hawks.

Not all monetary policy meetings are created equal, however. Staff projections are updated quarterly, and meetings with new projections are natural venues for decisions the ECB wants to ground in a fresh baseline and risk assessment.

That makes the roster arithmetic most salient at the projection meetings. Of the four, June and September are close to neutral on hawk/dove exclusions. December, by contrast, is one of the most dovish-skewed rosters of the year, but it is also nearly a year away.

March, therefore, is the meeting to watch in a present-tense sense. It combines updated projections with a voting roster that removes five hawks—Müller, Nagel, Vujčić, Makhlouf and Patsalides—while sidelining only one dove, Stournaras.

If a knife-edge decision were to arise early in the year, March is the point at which rotation is most likely to increase the odds that the outcome, or at least the ECB’s messaging around it, lands on the dovish side of the Council’s internal balance.
