Vietnam Petrol Prices Rise; 0% Special Consumption Tax on Petrol Under Review

Overview

Vietnam’s joint Ministry of Industry and Trade and Ministry of Finance adjustment lifted retail petrol and diesel prices by 220-690 VND per litre or kilogram from 15:00 on the pricing date, tracking a firmer global market. The same policy discussion opened a second, larger question for listed energy names: a proposal to cut the special consumption tax on petrol to 0% from November 1 to March 31, 2027, now under review by the Ministry of Finance. The development touches Petrolimex (PLX) on HOSE, PVOIL (OIL) and Bình Sơn Refining (BSR).

Key Facts

• Retail E10 RON 95-III rose 520 VND to 25,730 VND per litre; E5 RON 92 rose 660 VND to 26,020 VND per litre.
• Diesel increased 690 VND to 30,240 VND per litre; mazut rose to 23,590 VND per kg.
• Regional feedstock RON92 for E5 blending averaged USD 138.6 per barrel, up 4.68% over the period; diesel averaged USD 172.6 per barrel, up 2.71%; mazut USD 810.4 per tonne, up 1.2%.
• The operator suspended contributions to and drawdowns from the petrol price stabilisation fund for all products this cycle.
• At an October 27 meeting on petrol and power price scenarios, Deputy Prime Minister Nguyễn Văn Thắng assigned the Ministry of Finance, with the Ministry of Industry and Trade, Ministry of Justice and related agencies, to review the legal basis and feasibility of cutting the special consumption tax on petrol to 0% from November 1 to March 31, 2027.
• Under the Special Consumption Tax Law effective July 1, rates are 10% for conventional petrol, 8% for E5 and 7% for E10; the tax was previously cut to 0% from late March to end-June 2026.
• Environmental protection tax on petrol and diesel remains at 0 VND per litre, and the products remain outside VAT declaration under a policy extended through end-2026.

What Happened

According to the joint ministry price announcement, global petroleum markets over the prior seven days were driven by Houthi attacks on Saudi Arabian oil infrastructure, a drawdown in US crude inventories, and higher diesel output from Russian refineries. Average world prices rose across all grades between the two adjustment cycles, feeding directly into the domestic pass-through.

The tax element came from a separate October 27 meeting on petrol and electricity price scenarios, where Deputy Prime Minister Nguyễn Văn Thắng directed the Ministry of Finance to lead a review of the legal basis and feasibility of a 0% special consumption tax on petrol. The article does not state whether a formal draft decree has been issued, nor does it disclose the expected revenue cost of the measure. The proposal follows an earlier 0% window running from late March to end-June 2026, indicating the mechanism has already been used as a price-stabilisation tool.

Market Context

PLX closed at 34,000 VND on October 29, 2026, with BSR at 27,650 VND and OIL at 12,700 VND. All three trade in the oil and gas sector, where earnings are driven by the spread between import or refinery gate costs and regulated retail prices rather than by volume growth alone. The current cycle is unusual in that the stabilisation fund was neither contributed to nor drawn upon, leaving the retail price fully exposed to world benchmarks. The broader Vietnamese market has been sensitive to administered-price decisions on fuel and electricity because of their direct pass-through into CPI.

Strategic Significance

The 0% tax proposal, if enacted, would lower the retail price ceiling without compressing distributor margins, since the tax sits between the landed cost and the pump price rather than inside the distributor’s spread. For PLX and OIL that supports volume and reduces the risk of demand destruction at current price levels; for BSR it supports refinery-gate offtake. The more durable signal is policy direction: the repeated use of tax cuts as a shock absorber suggests the government is willing to forgo fiscal revenue to cap inflation, which lowers the tail risk of administered price caps that would squeeze distributor margins directly. The open question is duration. A window ending March 31, 2027 is temporary by design, so the market should treat it as a cyclical support rather than a structural re-rating of the sector.

What to Watch

• Formal issuance of a draft or decree on the special consumption tax cut, and its stated effective dates.
• The Ministry of Finance’s estimate of revenue forgone, which would indicate the scale of the intervention.
• The next joint ministry price adjustment cycle and whether the stabilisation fund is reactivated.
• Brent and regional RON92 crack spreads, given the full pass-through now in effect.
• Third-quarter and full-year 2026 earnings for PLX, OIL and BSR, showing volume and inventory effects from the higher price environment.
