Given the facts that Thai refineries still have to compete with imports from Singapore and that Singapore petroleum product price movements are in line with those in other markets, but with less price fluctuation, Thailand’s petroleum product pricing based on Singapore spot prices is considered the most appropriate for the time being. Nevertheless, since Thailand exports a portion of petroleum products at lower prices than distribution prices in the country, domestic consumers should benefit from the cheaper export prices. Currently, oil refineries have, at intervals, given discounts to oil traders; the latter will then deduct such discounts from their domestic distribution prices in certain areas. If the decrease in distribution prices can be expanded nationwide through a permanent decrease of ex-refinery prices to be close to export prices, consumers will be benefited as a whole.
