BP plc's shares are trading higher after OPEC maintained its growth forecasts and predicted a supply shortfall. This suggests that global oil supply may be constrained relative to demand, leading to an increase in oil prices. BP, as a major oil and gas company, can benefit from higher oil prices as it can sell its oil and gas products at higher prices, potentially boosting its revenues and profits. Global oil markets are anticipated to face a significant supply deficit exceeding 3 million barrels per day in the next quarter, possibly the largest in over a decade.
