Petrolimex (PLX): Vietnam Retail Fuel Prices Rise; 0% Petrol Tax Under Review

Overview

Vietnam’s Ministry of Industry and Trade announced a retail fuel price increase effective 15:00 on October 29, lifting E5RON92 by 666 VND/liter to 26,027 VND/liter and diesel 0.05S by 696 VND/liter to 30,246 VND/liter. The adjustment directly affects Petrolimex (PLX) on HOSE and the wider listed energy complex, including PV Oil (OIL), Bình Sơn Refining (BSR), PV Drilling (PVD) and PetroVietnam Technical Services (PVS). Separately, Deputy Prime Minister Nguyễn Văn Thắng has tasked the Ministry of Finance with assessing a proposal to cut the special consumption tax on petrol to 0% from November 1, 2026 to March 31, 2027.

Key Facts

• E5RON92 rose 666 VND/liter to 26,027 VND/liter, effective 15:00 on October 29.
• E10RON95-III rose 521 VND/liter to 25,734 VND/liter, now 293 VND/liter below E5RON92.
• Diesel 0.05S rose 696 VND/liter to 30,246 VND/liter; mazut 180CST 3.5S rose 223 VND/kg to 23,596 VND/kg.
• The inter-ministerial Công Thương - Tài chính group made no stabilization fund appropriation for any product this cycle, versus 300 VND/liter previously for biofuel petrol.
• The Ministry of Finance must complete its review of the 0% petrol excise tax proposal before November 1.
• The proposed 0% rate would run from November 1, 2026 through March 31, 2027.
• The ministry cited Houthi attacks on Saudi oil infrastructure, falling US crude inventories, expected OPEC+ output discipline in December and the Russia-Ukraine conflict as drivers.

What Happened

According to the Ministry of Industry and Trade notice, the joint Công Thương - Tài chính price management team raised all common retail fuel grades at the 15:00 October 29 adjustment. The ministry attributed the move to a mix of geopolitical and supply factors: fighting between Houthi forces and the Yemeni government alongside continued attacks on Saudi Arabian oil facilities, a drawdown in US crude inventories, expectations that OPEC+ will hold its December output target, higher diesel production at Russian refineries, and the ongoing Russia-Ukraine conflict.

This cycle the regulators did not appropriate funds into the petrol price stabilization fund for any product, having previously set aside 300 VND/liter for biofuel petrol, and continued to suspend disbursements for most grades. The article notes that after four consecutive increases in September, prices fell in two mid-October adjustments before turning higher again in the final October cycle. On September 30 the government issued a resolution extending excise and related tax cuts on fuel to stabilize prices and ease inflation pressure, and the Ministry of Industry and Trade has separately urged measures to prevent supply disruption.

Market Context

Petrolimex (PLX) closed at 35,350 on October 28 on HOSE, with PV Oil (OIL) at 13,100, Bình Sơn Refining (BSR) at 28,750 and PV Drilling (PVD) at 18,800. The price-context block does not include PVS, and the source article does not provide trading volumes or index levels. Retail fuel pricing in Vietnam is administratively set on a periodic cycle, so the direct read-through for PLX is to inventory gains and revenue per liter rather than to a freely clearing price; for BSR, higher product cracks support refining margins, while PVD and PVS are more exposed to upstream capital spending than to pump prices.

Strategic Significance

The more consequential item for long-term holders is the proposed 0% special consumption tax on petrol for November 2026 through March 2027, which would lower the retail price wedge and could support volume through the distributor network if crude stays elevated. For PLX, the thesis rests on volume and inventory timing rather than on the regulated per-liter margin, so a tax cut that lifts demand without compressing the allowed margin is the favorable combination. The absence of stabilization fund appropriations this cycle also means retailers are carrying less deferred cost on the balance sheet, a cleaner earnings profile than in periods of heavy fund accrual.

What to Watch

• The Ministry of Finance’s report on the 0% petrol excise tax proposal, due before November 1.
• The next retail price adjustment cycle and whether the stabilization fund appropriation resumes.
• OPEC+ December output guidance and US crude inventory data, both cited as drivers.
• Third-quarter earnings disclosures from PLX and BSR for inventory and margin effects.
• Any Ministry of Industry and Trade supply-security directive if Middle East tensions escalate.
