Oil prices weakened in Q3 as global supply outpaced demand and inventories swelled.
Brent crude fell 1.7 percent to end the quarter at US$65.90 per barrel, while West Texas Intermediate dropped to US$62.33. Deloitte’s latest energy report attributes the decline to rising stockpiles and OPEC+’s early decision to unwind production cuts, adding 1.37 million barrels per day in October.
The US Energy Information Administration noted supply exceeded demand by 1.6 million barrels per day between May and August, pointing to continued stock builds ahead.
“OPEC+ discipline is still somewhat unpredictable — its production signals are becoming more tactical rather than structural,” Isaev wrote. “On the other hand, US shale is adjusting to price signals with a focus on capital restraint instead of just ramping up volume. LNG shipments to Europe and Japan are turning into geopolitical tools, not just simple commercial agreements.”
As for how that could affect energy stocks, he stated, ‘The advantage will go to those (companies) who can skillfully navigate this complexity, foresee critical turning points, and invest their capital with both accuracy and creativity.’
