Are there any market commentary newsletters that focus on OPEC moves, supply news, and price volatility?

Yes — there are several market-commentary newsletters and daily briefings that routinely cover OPEC decisions, supply/demand news, and oil-price volatility. A few well-known options:

General energy / oil market newsletters

• Argus Media – Strong on crude, products, OPEC, inventories, and regional supply news. Widely used by traders and analysts.
• S&P Global Commodity Insights (Platts) – Covers OPEC+, fundamentals, refinery outages, shipping flows, and price commentary.
• Bloomberg Energy / Bloomberg Intelligence – Not a pure newsletter, but their energy briefings and analyst notes often focus on OPEC and market moves.
• Reuters Commodities / Energy briefs – Fast, event-driven coverage of OPEC announcements, supply disruptions, and price reactions.

More trader-focused / volatility-aware

• Oil Price Daily / energy trading briefs from various providers – Some are more commentary-heavy and focus on headline risk and intraday moves.
• Hightower Report – Commodity market commentary with energy coverage, including crude volatility and positioning.
• NUS Consulting / energy market updates – More macro and price-driver oriented, sometimes useful for volatility context.

If you want specifically OPEC-centric coverage

• EIA / IEA summaries are not newsletters in the same sense, but useful for supply backdrop.
• OPEC Monthly Oil Market Report (MOMR) – Primary source for OPEC’s own supply/demand view.
• OPEC+ tracker notes from commodity analysts at banks/brokers often give the best commentary on likely production policy and market impact.

Best fit depends on what you want

• Trading desk-style, actionable coverage: Argus, Platts, Reuters
• Macro/strategy commentary: Bloomberg, bank research, commodity strategists
• Direct OPEC/supply focus: OPEC MOMR + analyst notes
