MANILA — Oil companies in the Philippines have signaled that fuel price adjustments will be mixed this week, citing volatility in energy markets and uncertain security conditions in the Persian Gulf.

The changes were laid out in price adjustment advisories issued on Monday and will be reflected in pump prices on Tuesday. Such weekly announcements are standard practice in the Philippine fuel retail market, where pump prices track movements in international oil rates — a mechanism that lets shifts in global supply conditions reach consumers within days.

Shell Pilipinas Corp. and Petron Corp. said they will raise gasoline prices by P1.90 per liter and kerosene prices P3.30 per liter, while cutting diesel prices by P1.30 per liter.

Seaoil Philippines, Inc. will raise gasoline prices by P1.93 per liter and kerosene by P3.30 per liter, with diesel prices set to fall by P1.30 per liter.

Jetti Petroleum, Inc., meanwhile, will hike diesel prices by P1.30 per liter and gasoline prices by P1.90 per liter.

The result is a divergent picture at the pump: higher costs for gasoline and kerosene, alongside continued relief on diesel, a fuel widely used in Philippine transport and freight. This week's diesel increase only partially claws back last week's P7.57-per-liter rollback, leaving diesel cheaper than it stood two weekly cycles ago.

Last week, the industry implemented rollbacks of P0.24 per liter for gasoline, P7.57 per liter for diesel, and P5.85 per liter for kerosene.

The Department of Energy (DOE) had not announced its own prescribed price adjustments as of the deadline. The agency gained the authority to guide fuel prices during the energy emergency, and how that power is eventually used alongside the companies' weekly advisories remains among the items to watch.

Jetti Petroleum President Leo P. Bellas said oil prices were volatile this week due to reports that another United States aircraft carrier was heading to the Gulf, China's decision to curb exports of refined petroleum products, and the extension of Russia's diesel export ban.

These factors, he said, offset easing supply concerns as Middle Eastern oil flows recovered. With pump prices reset weekly against that backdrop, the next round of advisories — and any DOE announcement — will offer the next reading on how these crosscurrents filter through to consumers. — Sheldeen Joy Talavera
