Just when OPEC seemed to have finally mastered the long-running problem of members breaching their oil-output targets, a new offender is emerging.
The United Arab Emirates -- traditionally a loyal partner of group leader Saudi Arabia -- pumped a little bit over its agreed limit in July, according to OPEC data. It has admitted doing so again in August.
Now, many traders are turning their attention to data showing the Gulf state’s excess may be far greater than previously believed, contributing to the drop in crude prices to a two-month low.
The strongest signal that something was amiss came last month from the International Energy Agency, which estimated in its closely watched oil market report that the UAE pumped 3 million barrels a day in July. According to Petro-Logistics SA, which tracks international oil-shipping movements, the country supplied even more than that in August.
