OIL PRICE WATCH as of Oct. 20, 2026
By Saghir Hussain ·
Oil prices are moving in opposite directions across the pump — and that split tells you more about the global economy than any single headline figure.
The Philippine signal
Manila's latest adjustment lays bare the distortion. Gasoline drops P4.30 a litre. Kerosene falls P1. Diesel, the fuel of logistics, agriculture and public transport, climbs again. After two weeks of across-the-board rises, the rollback on petrol looks like relief. For the jeepney driver in Quezon City or the rice farmer in Bukidnon, it is not. Their costs stay pointed up.
The Department of Energy attributes the split to "divergent product cracks" in Singapore — the regional pricing hub. Translation: refiners are chasing petrol margins while diesel stays tight. That is not a local quirk. It is a structural shift visible from Rotterdam to Houston.
Refinery economics, geopolitical floor
European refineries have cut runs since summer. Maintenance backlogs from 2024, weaker petrol demand from EV adoption, and the loss of Russian diesel flows have reconfigured the barrel. OPEC+ discipline holds — Saudi Arabia and Russia extended voluntary cuts through Q4 — but the cartel manages crude, not cracks. The product market prices itself.
In the US, Gulf Coast exports of diesel to Latin America and Europe hit record September volumes. Domestic stocks drew. The API weekly data showed a 3.2 million barrel distillate drop. That pulls Singapore cracks higher via arbitrage. Asian buyers pay the premium.
Meanwhile, Chinese teapot refineries in Shandong ramped throughput to 78% capacity — a 14-month high — flooding the region with petrol and jet fuel. Their diesel yield lags. The result: a petrol glut in Asia, a diesel squeeze everywhere.
Who pays, who profits
Small hauliers in the Philippines, Indonesia, Vietnam absorb the diesel rise. They cannot pass it on fast enough. Food prices follow — the Inquirer's parallel report on rice externalities notes transport now accounts for 18% of farm-gate-to-market cost. In the UK, road fuel duty freeze saves the motorist 5p a litre while HGV operators face 12% year-on-year diesel inflation. The politics of the pump protects voters, not logistics.
Oil majors report Q3 this week. Expect record downstream margins — again. The split barrel rewards integrated players who control both crude and retail. Independent refiners without marketing arms bleed.
The ground truth
Price watches focus on the headline. The reality is a two-tier energy transition: petrol demand peaks, diesel demand persists. No policy has solved for that. Until it does, every rollback on gasoline is a mirage for the people who move the world.
