In a surprise move, the OPEC+ alliance declared an additional voluntary output reduction of 1.2 million barrels per day, effective immediately. The decision was driven by concerns over a projected oversupply amid slower demand growth in China. Brent crude futures jumped 6 percent, settling at $92.5 per barrel, while West Texas Intermediate rose to $88.3. The rally reverberated through US markets, with energy‑focused ETFs such as XLE gaining 3.1 percent in pre‑market trading. Major oil majors saw their shares climb: Exxon Mobil (XOM) rose 5.4 percent, Chevron (CVX) added 4.9 percent, and ConocoPhillips (COP) jumped 5.2 percent. The cut also lifted natural‑gas prices, benefitting pipeline operators like Kinder Morgan (KMI). Analysts anticipate that the tighter supply outlook could sustain higher oil prices through the fourth quarter, providing a tailwind for energy sector earnings. Investors are advised to monitor geopolitical developments in the Middle East that could further influence supply dynamics.
