Petrol prices for Tongatapu will increase by 5 seniti per litre, while retail prices for all petroleum products will remain the same starting tomorrow, 1 October
The Ministry of Trade and Economic Development (MTED) advised that the October 2025 price change is based on the August 2025 average of the published daily Mean of Platts Singapore (MOPS) benchmark prices for product prices and freight, along with that month’s exchange rate.
The average Brent crude oil price for August was US$66.99/bbl lower than July. Petrol prices increased during August due to decreased supply from China. Diesel prices decreased during August due to increased Indian exports creating plentiful regional supply, and increased refinery runs, however partially reversed by the end of the month as supply from China decreased. Kerosene prices decreased during August due to increased Indian exports creating plentiful regional supply, and increased refinery runs. Again the end of the month, these decreased partially reversed as supply from China decreased.
Meeanwhile, average freight prices decreased in August primarily due to excess supply of vessels in the market earlier in the month, but from mid-August demand for shipments from Americas to Asia increased, offsetting some of the earlier price decreases.
The Tongan pa’anga weakened against the US dollar, thus increasing prices slightly.
The combined effects of the above movements, and with rounding up/down to the nearest 5 seniti, the retail prices for all petroleum products for Tongatapu will remain the same while Petrol prices increase by 5 seniti/litre.
Consumption tax is included in all price changes.
