Brent crude experienced significant volatility during the first two weeks of November 2025. Prices initially declined due to concerns about oversupply and weak demand signals, then regained some momentum as sentiment improved and new supply-side risks emerged. This report examines price movements during that period and the key factors that shaped the market's trajectory—including supply and demand dynamics, OPEC+ policy, US inventory data, geopolitical developments, and the overall economic environment.
OPEC+ Decisions and Oversupply Concerns
The outlook for oil supply was one of the main factors weighing on Brent prices at the beginning of the month. On November 3, the OPEC+ alliance agreed to a slight increase in production of approximately 137,000 barrels per day for December, while simultaneously indicating a freeze on any further increases during the first quarter of 2026.
These decisions sent mixed messages to the market: the limited increase in December implies more supply in the short term, reinforcing concerns about a return to a surplus market, while the anticipated freeze at the beginning of 2026 reflects the oil cartel's awareness of the risk of oversupply and its attempt to contain it.
These concerns come amidst a three-month downward trend in prices that lasted until October, as reflected in Brent crude prices on the Plus500 platform, stemming from worries that the pace of production increases—both from OPEC+ and non-OPEC producers—may outpace global demand growth. Since August 2025, the alliance has begun a gradual rollback of previous production cuts, while non-OPEC producers have also increased their output. Some analysts have described the situation as “the most obvious and predictable supply glut in history,” suggesting that the market had already prepared for a significant supply surge at the end of 2025. Actual data supported these projections. A Reuters survey showed that OPEC production rose again in October, while US output remained near record highs. Furthermore, the International Energy Agency (IEA) predicted that the global market could see a surplus of up to 4 million barrels per day in 2026 if production growth continued unchecked. Meanwhile, Saudi Arabia—the de facto leader of OPEC—cut its official selling prices to Asia for December to remain competitive in an oversupplied market.
Against the backdrop of this tight supply picture, there were worrying signs on the global demand side. Oil consumption around the world appeared to be weaker than expected. Analysts at JPMorgan Chase noted in a client note that global consumption had risen by about 850,000 barrels per day from the beginning of the year through early November—less than their previous forecast of nearly 900,000 barrels per day. Other indicators showed a decline in fuel consumption in key markets, particularly the United States, where weak travel and reduced overland freight shipments reflected sluggish US oil demand. Indeed, inventory data reflected a widening gap between supply and demand. After a limited drawdown at the end of October, the trend quickly reversed, with the US Energy Information Administration reporting a significant increase in crude oil inventories of approximately 5.2 million barrels in the first week of November.
Globally, demand signals were equally discouraging. In Asia, China has experienced a slowdown in oil consumption growth in recent years, coinciding with its expansion into cleaner energy sources. This decline in Chinese demand, coupled with weak consumption in Europe and other regions, meant that global demand was not strong enough to absorb the increase in supply. While India provided some support with growing domestic demand, the overall picture remained bleak at the beginning of November.
Geopolitical Developments and Supply Disruption Risks
Geopolitical developments played a dual role in Brent crude price movements, with one of the key issues being the impact of Western sanctions on Russian oil. In late October, the United States imposed a new round of sanctions on Russia’s largest oil companies. While the initial market reaction was bullish, traders grew more skeptical over time, believing the sanctions might not significantly disrupt Russian oil flows in the near term, given Moscow’s ability to find alternative export routes.
Despite these uncertainties, the risk of supply disruptions prevented prices from falling further. In early November, a major Russian refinery was struck by a Ukrainian drone, forcing it to halt production, while Lukoil declared force majeure at its West Qurna-2 oil field in Iraq due to the sanctions. Russia also announced it had thwarted drone attacks near a major Black Sea port.
Although none of these incidents resulted in a significant and immediate loss of supply, they highlighted the vulnerability of some oil sources, reinforcing the perception that a portion of the global supply could be disrupted at any moment. Macroeconomic Factors and the Role of Financial Markets
The overall economic situation and the direction of financial markets in November formed the primary backdrop for Brent crude oil price movements. In the first week, economic concerns and the rise of the US dollar to its highest level in several months weighed on oil prices. The United States was experiencing an unprecedented government shutdown, and by early November, its effects were becoming increasingly apparent. US stocks were highly volatile, and oil traders feared that the government paralysis would severely damage economic activity.
However, the landscape shifted at the beginning of the second week. Market sentiment improved as progress was made toward ending the government shutdown, leading to a rise in stock indices and a return of risk appetite. This contributed to the rise in Brent prices, as investors believed that a resolution to the crisis would support economic activity and restore some confidence to consumers.
Monetary policy also played a role. In late October, the US Treasury cut interest rates.
