Oil Prices Fall After Rumors of Production Increase from Opec+ and the Risk of U.S. Government Shutdown That Could Affect the Global Energy Market.
On the morning of Wednesday, October 1, 2025, oil prices started the day lower, reflecting a combination of global uncertainties. The market reacted to both the Opec+ negotiations regarding possible production increases and concerns over the partial shutdown of the United States government.
At 07:08 AM (Brasilia time), Brent for December was down 0.33%, priced at US$ 65.81 per barrel, while WTI for November fell 0.34% to US$ 62.16 per barrel. These numbers add to the significant losses of the previous two days, when international benchmarks dropped more than 3% on Monday and 1.5% on Tuesday, marking the largest streak of declines since August.
Impact of Opec+ and Excess Supply Risks
According to analysts, the pressure on prices mainly comes from the supply side. Opec+ is considering allowing an increase of up to 500,000 barrels per day in November, three times more than the increase recorded in October. Internal sources within the group confirmed that the debate ranges between 274,000 and 411,000 barrels but do not rule out the larger figure.

In an official statement, however, Opec+ classified as “misleading” the reports that already treated the 500,000-barrel increase as decided. Despite the denial, investors remain cautious in light of the more aggressive stance from Saudi Arabia and its allies, who seek to regain market share internationally.
Another factor that affected expectations was the release of data from the American Petroleum Institute (API). The report showed a decrease of 3.67 million barrels in crude oil inventories, but at the same time, an increase of 1.3 million barrels in gasoline and 3 million in distillates.
According to specialist Sugandha Sachdeva from SS WealthStreet, this movement reduces some of the optimism. “Although U.S. crude oil inventories are in a downward trend, the pace of reduction has slowed, moderating the bullish sentiment,” she assessed.
U.S. Shutdown Increases Tension
Meanwhile, in Washington, the political crisis adds uncertainty. The partial shutdown of the U.S. government, which began on Wednesday, puts strategic sectors at risk and could cost US$ 400 million per day. Among the expected impacts are the suspension of payments to troops, the furlough of 750,000 federal workers, the interruption of scientific research, and even delays in air travel.
This paralysis is also expected to delay the release of the much-anticipated September non-farm payroll report, a key indicator for measuring the strength of the U.S. economy and, consequently, future fuel demand.
In addition to the pressure in the U.S., industrial surveys in Asia have reinforced the atmosphere of concern. Strategic sectors reported contraction in September, driven by the decline in Chinese demand, the slowdown in U.S. growth, and fears of new trade tariffs.
Given this scenario, experts assess that oil prices remain vulnerable to Opec+ decisions, the direction of the global economy, and the political tensions that directly influence energy consumption.
