A mixed movement in pump prices is expected next week, with gasoline poised for a hefty rollback while diesel could see a slight increase.

Domestic pump prices are expected to fluctuate due to external factors impacting global oil prices, according to Energy Secretary Raphael Lotilla.

Rates of the Manila Electric Co. are up this month due to higher generation charge, ending two straight months of rate reductions for more than 7.7 million Meralco customers.

Pump prices could stay the same or see minimal adjustments next week.
