Com the increase of $6.51 in relation to the Friday quotation (116.60 dollars), the barrel used as reference by OPEC records six consecutive discharge sessions since September 4, accumulating a valuation of 26%.
This rise followed the reference Brent oil for Europe, and the US reference Texas (WTI), which on Monday also closed at 105.68 and 101.39 dollars per barrel, respectively.
This reflects the composition of the OPEC barrel, consisting of twelve types of crude (one per member country, including one of the Emirates, although the United Arab Emirates abandoned the organization last May), of which the main ones are extracted in the Middle East and are directly exposed to the geopolitical and logistical impact in the region.
Analysts attribute the most recent increases to the ‘preventive’ closure of the East-West Saudi pipeline, located in the Riyadh and Medina regions, announced by Saudi authorities on Friday, after the installation has suffered several attacks.
The pipeline is one of Saudi Arabia's main alternative routes to export crude oil without crossing the Ormuz Strait, where oil traffic remains affected.
In recent days, fighting has intensified near the narrow strategic of Bab al-Mandeb, which links the Red Sea to the Gulf of Aden.
Over the year, the average price of OPEC reference barrel is $97.70, a value more than 40% higher than the average of US$65.59 recorded throughout the year 2025.
