Fluctuations in Murban crude oil supply have been causing trouble for traders, putting the reputation of the Abu Dhabi National Oil Company to the test.

According to the Zhitong Finance APP, the confusion surrounding the flagship Murban crude oil supply of the Abu Dhabi National Oil Company (Adnoc) this month has left traders frustrated and questioning official information about production levels. Last month, Adnoc had announced a cut in the supply of Murban crude oil for July, but some buyers later received notifications that they would receive their full quota. Prior to this, Adnoc had also unexpectedly reduced export volumes for the coming months at the end of May, only to make adjustments just days after releasing initial shipment forecasts for 2026.
