Vietnam Draft Decree Would Let Petrolimex (PLX) Set Its Own Fuel Prices

Overview

Vietnam’s Ministry of Industry and Trade has circulated a draft decree that would end state-set retail fuel prices, handing pricing authority to petroleum wholesalers and distributors, with the state intervening only during abnormal market swings. The proposal directly affects Petrolimex (PLX), the country’s largest fuel retailer, which would gain pricing flexibility but also absorb new regulatory and margin risk.

Key Facts

• The draft decree would remove the state’s retail price ceiling; fuel prices would be set by the market and by businesses, per Trần Hữu Linh, Director of the Domestic Market Management and Development Department at the Ministry of Industry and Trade.
• Retail prices would be decided by key wholesalers using a state-prescribed formula: purchase price plus sourcing costs, standard business costs, profit and taxes.
• Distributors within a wholesaler’s system could not sell above the price published by that wholesaler.
• The Petrolimex (PLX) stabilization fund would move to the State Treasury under the Ministry of Finance; businesses must lock in fund balances and transfer positive balances to the Treasury account.
• Linh said the mechanism accepts that each fuel station may post a different price, and that a price could change between morning and afternoon.
• Đỗ Hoàng Hà, Head of Business at Petrolimex, said the absence of specific rules on when distributors may adjust prices could create problems at the explanation stage.
• PLX closed at VND 36,650 on 1 October 2026 on HOSE.

What Happened

Speaking to Tuổi Trẻ, Trần Hữu Linh said fuel has always been a state-priced commodity in Vietnam, particularly the retail ceiling. Under the draft, the state would no longer set retail prices and would intervene only when the market shows unusual volatility. All import, sourcing, standard business cost, profit and tax components would be decided by the business and its distribution system, he said.

The draft also sets out a stabilization mechanism. If the market price level moves abnormally with large impact, the Ministry of Industry and Trade would coordinate with other ministries to assess the severity and submit a document to the Government for a decision on stabilization measures. The price stabilization fund would be managed by the State Treasury rather than held at enterprises. Petrolimex’s Đỗ Hoàng Hà raised concerns that allowing distributors to buy from multiple sources and set and adjust prices without specific timing rules could cause difficulties, particularly if a distributor cuts prices below its wholesaler and the wholesaler later raises them.

Market Context

PLX trades on HOSE and closed at VND 36,650 on 1 October 2026. Petrolimex is the dominant name in Vietnam’s oil and gas retail sector, and its earnings are sensitive to the spread between import costs and regulated retail prices. The draft decree is part of a broader Vietnamese policy shift toward market-determined pricing in administered sectors, and it lands as global fuel prices remain a key input into domestic inflation and transport costs.

Strategic Significance

For long-term investors, the core question is whether pricing freedom expands Petrolimex’s margin or exposes it to competitive undercutting. A market-based formula could let PLX pass through import cost increases faster than the current ceiling allows, supporting gross margins during upcycles. But the same freedom lets smaller distributors compete on price, and the shift of the stabilization fund to the State Treasury removes a buffer that has historically smoothed earnings. The draft’s intervention trigger, which is not yet quantified, is the main swing factor: a low threshold preserves the status quo in practice, while a high one makes PLX’s earnings more cyclical.

What to Watch

• The final decree text and whether it specifies a concrete volatility threshold for state intervention.
• Government or National Assembly feedback on the draft, and the timeline for issuance.
• Petrolimex’s disclosure on the transfer of its stabilization fund balance to the State Treasury.
• PLX quarterly earnings and any commentary on retail margin trends after the new pricing mechanism takes effect.
• Competitor pricing behavior among major wholesalers once the ceiling is removed.
