OPEC Meeting Schedule 2027
OPEC and its OPEC+ allies do not publish a fixed annual calendar the way central banks do — each meeting date is confirmed by press release, usually one to three weeks ahead. What is predictable is the cadence: full ministerial meetings (ONOMM) roughly every one to two months, monthly Joint Ministerial Monitoring Committee (JMMC) reviews in between, and extraordinary sessions whenever the market demands one. The expected 2027 windows below follow that established pattern and are updated as official dates are confirmed.
When is the next OPEC meeting?
The next OPEC+ gathering is the JMMC expected in Early January 2027. OPEC confirms the exact date by press release on opec.org, and the decision statement is published when the session concludes — typically late morning to mid-afternoon Vienna time (CET), which is early to mid-morning in New York.

Expected 2027 OPEC / OPEC+ meeting windows
| Expected window | Meeting type | What to watch |
|---|---|---|
| Early January 2027 | JMMC | First monitoring review of the year — compliance with the current output agreement and any carry-over compensation plans. |
| Late January / early February 2027 | Ministerial (ONOMM) | First full OPEC+ ministerial of 2027; sets or confirms Q1 output policy. |
| Early March 2027 | JMMC | Monitoring review ahead of the spring ministerial — watch for language on unwinding voluntary cuts. |
| April 2027 | Ministerial (ONOMM) | Spring policy meeting; historically a live date for mid-year production target changes. |
| Late May / early June 2027 | Ministerial (ONOMM) | The traditional mid-year meeting — OPEC's June Conference slot — where H2 policy is set. |
| July 2027 | JMMC | Summer monitoring review; usually a confirmation exercise unless the market has moved sharply. |
| August / September 2027 | Ministerial (ONOMM) | Late-summer meeting; watch for baseline and quota renegotiation headlines. |
| October 2027 | JMMC | Monitoring review ahead of the year-end ministerial round. |
| Late November / early December 2027 | Ministerial (ONOMM) | Year-end meeting — the 2028 policy framework is typically agreed here. |
Windows are indicative, based on the OPEC+ meeting cadence since 2022 — they are not confirmed dates. OPEC confirms each meeting by press release, and extraordinary meetings can be called at short notice. This page is updated as official 2027 dates are announced.
How OPEC decision days actually run
Unlike a central bank, there is no scheduled release time. Ministerial meetings are held in Vienna or by video conference, and the first market-moving information is usually wire headlines from delegates while the session is still running — the official communiqué lands on opec.org only after the meeting closes, typically late morning to mid-afternoon CET. That means oil can trade the rumour for hours before the fact. The JMMC, by contrast, is a monitoring body: it reviews compliance and can recommend policy changes, but only the full ministerial meeting can set quotas. The other dates that matter around the meetings are the monthly OPEC oil market report (usually the second week of the month) and, for the voluntary-cut group, the compensation schedules members file for past overproduction.
Why OPEC meetings move macro, not just oil
OPEC+ controls roughly 40% of global crude supply, so its quota decisions feed straight into the inflation prints that drive central bank policy — a surprise cut lifts energy CPI components within weeks and can shift the expected Fed, ECB and BoE rate paths priced by rates markets. The transmission runs wider than crude: Brent and WTI set the tone for energy equities and high-yield credit, CAD and NOK track the oil beta, refining margins and airline stocks move on the crack spread, and a sustained supply squeeze is one of the few shocks that can move breakeven inflation rates on its own. That is why OPEC+ ministerial days sit alongside CPI and FOMC as the highest-volatility sessions on the macro calendar.
