Why prices moved: Dubai crude rose about $8.90 a barrel. International gasoline rose about $6.50 a barrel, diesel rose about $11.40 and kerosene rose about $11.50. The peso weakened from ₱60.91 to ₱61.18 per US dollar, which makes imported fuel more expensive. (Trading week of August 10 to 14, 2026; figures from the Department of Energy's Oil Monitor.)
