Motorists will endure a new round of slight increases in the pump prices of petroleum products starting tomorrow morning, 28 November, due to supply constraints, which will cut the four-week streaks of rollbacks.

In separate advisories today, local oil companies announced that the prices of diesel will inch up by 30 centavos per liter and kerosene by 65 centavos per liter. Gasoline prices, on the other hand, will not move.

The Department of Energy Oil Industry Management Bureau or DOE-OIMB said the price movement was triggered by the supply cuts to be implemented by members of the Organization of the Petroleum Exporting Countries.

The latest data from the DOE-OIMB showed that gasoline increased by P12.30 per liter from the start of the year until 21 November, while diesel and kerosene both logged a cumulative increase of P5.70 per liter and P1.09 per liter, respectively.

Oil companies announce price adjustments every Monday to be implemented the morning of the following day.

They adjust their prices weekly based on the movement of the Mean of Platts Singapore — the regional pricing benchmark adopted by the deregulated downstream oil sector.
