Vietnam Petrol Prices Fall to 21,150 VND as PLX, OIL, BSR Face Margin Squeeze

Overview

Vietnam’s inter-ministerial price regulator cut domestic petrol and oil prices by 180-2,310 VND per litre from 15:00 today, taking E10 RON 95-III to 21,150 VND per litre and E5 RON 92 to 20,890 VND. The move follows a near-11% fall in world RON95 feedstock prices between the 3 November and 5 November pricing windows. It matters for HOSE-listed Petrolimex (PLX), PVOIL (OIL) and Binh Son Refining and Petrochemical (BSR) because it resets the retail and refinery pricing base while a temporary zero rate of special consumption tax on petrol runs from 1 November to end-March 2027.

Key Facts

• E10 RON 95-III cut by 2,080 VND per litre to 21,150 VND; E5 RON 92 cut by 2,310 VND to 20,890 VND, effective 15:00 today.
• Diesel fell to 28,690 VND per litre and mazut to 22,000 VND per kg, with oil products down 180-1,970 VND per litre or kg.
• World RON95 feedstock for E10 blending fell nearly 11% to USD 113.9 per barrel between the 3-5 November windows; diesel slipped 0.44% to USD 163.6 per barrel and mazut dropped about 11.3% to USD 732.8 per tonne.
• The special consumption tax on petrol was cut to 0% from 1 November through end-March 2027, worth an estimated 1,575-1,804 VND per litre at the pump and a budget shortfall of more than VND 7,672B.
• Petrol prices have fallen in three consecutive adjustments since early November, with E5 RON 92 down more than 5,100 VND per litre and E10 RON 95-III down almost 4,600 VND in total.
• The regulator resumed provisioning the petrol price stabilisation fund at 700 VND per litre for biofuel petrol and 500 VND per kg for mazut, while halting fund drawdowns for all products.
• Eleven firms are licensed to blend E10 biofuel petrol with combined capacity of 1.41 million cubic metres per month, against monthly demand of about 1 million cubic metres.

What Happened

The joint Ministry of Industry and Trade and Ministry of Finance adjustment cited the US midterm election outcome and Saudi Aramco’s crude pipeline expansion plan as drivers of the world energy price decline. Finished product prices fell across all grades between the 3 November and 5 November pricing cycles, with RON95 feedstock for E10 blending down nearly 11% to USD 113.9 per barrel. The ministries set the new retail ceilings accordingly and reintroduced stabilisation-fund provisioning after a period of drawdowns.

The tax change is the larger structural item. From 1 November, the special consumption tax on petrol is zero through end-March 2027, which the article estimates lowers pump prices by 1,575-1,804 VND per litre and costs the budget more than VND 7,672B. E10 RON 95-III has been sold nationwide since 1 June, fully replacing mineral petrol. At a 4 November government press conference, Deputy Minister of Industry and Trade Luong Hoang Thai said the ministry had received 315 comments on E10, mostly in June and July, with almost none in the past two months.

Market Context

PLX on HOSE last closed at 33,500 VND (4 November), OIL at 12,900 VND (4 November) and BSR at 26,000 VND, down 0.94% on volume of 3.87 million shares (5 November). The retail price cut lands directly on PLX and OIL, whose distribution margins are set within the regulated pricing band, while BSR’s refining spread depends on the gap between crude and product prices rather than the domestic retail ceiling. The three consecutive declines since early November return E10 prices to levels last seen in early March, when Middle East conflict broke out, meaning the sector gives back the geopolitical premium that supported shares earlier in the year.

Strategic Significance

The zero special consumption tax is a demand-support measure dressed as a price cut. By removing 1,575-1,804 VND per litre of tax through March 2027, the government absorbs the revenue hit rather than letting distributors carry it, which protects PLX and OIL retail volumes but caps the per-litre margin they can earn. For BSR, the relevant variable is the Singapore product crack, not the domestic ceiling; a near-11% drop in RON95 feedstock in one cycle compresses the refining spread if crude does not fall in step. The structural overhang is E10 blending capacity of 1.41 million cubic metres per month against demand of about 1 million, which keeps blending margins competitive and reinforces the shift away from imported mineral petrol.

What to Watch

• The next pricing adjustment cycle and whether the 21,000 VND threshold on E10 RON 95-III holds.
• November and December trade data on petrol import volumes and E10 blending utilisation.
• BSR’s Q4 refining spread versus the Singapore RON95 crack and crude differentials.
• Any National Assembly guidance on extending the 0% special consumption tax beyond March 2027, given the VND 7,672B revenue gap.
• PLX and OIL Q4 earnings disclosures on retail volume and per-litre margin.
