Brent crude oil futures advanced 1.5% to $65.5 per barrel on Monday on Monday after OPEC+ agreed to a modest increase in production, easing market fears of a larger supply boost. The producer group agreed on Sunday to raise production by 137,000 bpd in November, matching October's increase, with markets seeing it as a cautious move amid persistent worries about oversupply. OPEC+ described the latest decision as a response to a steady global economic outlook and current healthy market fundamentals, noting that output adjustments may be paused or reversed if conditions change. By the end of September, OPEC+ had already rolled back a 2.2 million bpd cut - a year ahead of schedule - and was in the process of unwinding an additional 1.65 million bpd cut. However, price gains were limited as concerns grew that the ongoing US government shutdown could weigh on economic growth and, in turn, dampen energy demand.
