When does OPEC+ announce its decisions?

After its meetings, whose dates are announced by OPEC. There is no fixed time of day, meetings are often held online, and some conclude on weekends. The official statement is published on OPEC's website.

Why does crude oil sometimes gap on Sunday evening?

If OPEC+ or other events produce news over the weekend, the first trades at the reopening of CME Globex price it all at once in a thin book, so the first bars can open far from Friday's close.

OPEC+ meetings: production decisions, weekend headlines and crude futures

OPEC+ is the alliance of OPEC members and partner producers such as Russia that coordinates oil production policy. Its ministerial meetings, monitoring committee sessions and the separate meetings of member groups with voluntary cuts have no fixed release time, are often held online and sometimes conclude on weekends. Crude oil futures (CL) can therefore reprice at the Sunday evening reopening rather than at a scheduled second.

How OPEC+ decides

OPEC+ groups the Organization of the Petroleum Exporting Countries with partner producers that joined through the Declaration of Cooperation in 2016. Full ministerial meetings set group-wide policy; a monitoring committee reviews conformity with agreed levels; and in recent years a smaller group of members that took additional voluntary cuts has met separately to decide how fast to restore or extend them.

The outcome is usually published as a statement on OPEC's website after the meeting. Before that, delegates and officials often speak to the press, so parts of the decision can circulate as headlines hours or days in advance.

Why the lack of a fixed time matters

There is no scheduled second to prepare for; liquidity can stay cautious for a long window rather than stepping back at a known instant.
Headlines attributed to unnamed delegates can move crude before the official statement, and the statement can confirm or contradict them.
Meetings that end on a Saturday or Sunday leave the reaction for the reopening of CME Globex on Sunday evening.
Postponed or rescheduled meetings are themselves news, as they often signal disagreement.

Why crude futures react

Production targets change expected supply. A decision to add barrels faster than expected, or to extend cuts, shifts the expected balance between supply and demand and reprices the futures curve, starting with the front months. The market also reads compliance: announced cuts that members do not implement matter less than the headline suggests. Energy-linked currencies and energy-heavy equity sectors can follow crude.

Order flow at the Sunday reopening

When a decision lands over a weekend, the first CL prints at the Sunday evening reopening absorb two days of news at once. The book is thin in the first minutes of the session, and the first bars can open away from Friday's close, leaving a gap. On the footprint, the reopening bars show whether the gap attracts aggressive orders that extend it or responsive orders that start to fill it.

Neither outcome is predictable from the gap alone. What the tape shows is who is active: a gap that extends on rising volume and one-sided delta, or a gap that stalls as passive size absorbs the initial aggression.

In Senzoukria

The economic calendar filters events by the nine zones it knows, US, EU, GB, JP, CN, AU, CA, CH and NZ; an event that the feed files under no single currency does not appear in that list, so do not rely on the calendar for OPEC+ meetings. Use the news wire instead: the ENERGY tag matches headlines that mention OPEC, crude or oil, and the CL / MCL preset combines the ENERGY, GEOPOLITICS and US tags.

A keyword alert on opec rings once per matching headline, on the wire refresh, on your machine only; the wire is delayed by about 15 minutes. On the chart, the Gap Open indicator marks bars that open at least four ticks (by default) from the previous close, which is where a weekend decision shows up.
