Petrol and Diesel Market Price vs. Formula Price in June 2025

Abstract

Fuel prices remained unchanged in June 2025, with the market price of Octane 92 petrol at LKR 293.00 and auto diesel at LKR 274.00. However, the formula price has dropped for both petrol and diesel.

The market price of petrol now exceeds the formula price by LKR 5.64, breaching the 3% allowable variation* threshold. Over the past four months, petrol prices remained aligned with the formula, but this month’s deviation is driven by a drop in global petrol prices—down by an average of LKR 1.62.

The market price of auto diesel in June 2025 exceeds the formula price by LKR 19.11—marking a further widening of the gap that has persisted over the last three months. This increase is due to the absence of a reduction in the market price, despite a fall in the formula price by LKR 5.56.
