Vietnam Fuel Price Cut: Petrolimex (PLX) Gasoline Down, Diesel Up

Overview

The Ministry of Industry and Trade issued a fuel price adjustment effective 15:00 on October 22, cutting E5RON92 gasoline by 1,610 VND/liter and E10RON95-III by 1,816 VND/liter while raising diesel 0.05S by 444 VND/liter and mazut 180CST 3.5S by 1,238 VND/kg. The move matters for Petrolimex (PLX) on HOSE, the country’s largest fuel retailer, and for the wider listed energy complex including BSR, OIL, PVD and PVS. It is the second consecutive cut for gasoline after a month and a half of increases.

Key Facts

• E5RON92 set at 25,361 VND/liter, down 1,610 VND/liter, effective 15:00 on October 22.
• E10RON95-III set at 25,213 VND/liter, down 1,816 VND/liter, now 148 VND/liter below E5RON92.
• Diesel 0.05S set at 29,550 VND/liter, up 444 VND/liter.
• Mazut 180CST 3.5S set at 23,373 VND/kg, up 1,238 VND/kg.
• The inter-ministerial Công Thương - Tài chính body suspended price stabilization fund drawdowns for most products, retaining a 300 VND/liter contribution on biofuel gasoline only.
• The government extended fuel tax cuts under a resolution dated September 30 to ease inflation pressure.
• September recorded four consecutive fuel price increases, extending into early October before the recent reversal.

What Happened

The Ministry of Industry and Trade announced the adjustment in a formal notice, applying the new retail prices from 15:00 on October 22, with fuel traders required to implement them no later than that time. The ministry attributed the mixed outcome to global product price movements, citing the resumption of US-mediated Russia-Ukraine peace talks, continued Houthi attacks on Saudi Arabian oil infrastructure, fires on tankers transiting the Strait of Hormuz, and the ongoing Russia-Ukraine conflict.

At this cycle, the inter-ministerial Công Thương - Tài chính did not set aside price stabilization fund provisions for most products, except a 300 VND/liter contribution on biofuel gasoline, and stopped fund disbursements for nearly all items. The ministry also instructed wholesale and producing traders to fulfil their assigned 2026 minimum supply volumes by quantity, grade and registered quarterly plan, to diversify domestic and imported supply, and to maintain mandatory reserves, with particular emphasis on ensuring adequate diesel supply in all scenarios.

Market Context

PLX closed at 35,850 on HOSE on October 22, the reference date for this price context. BSR closed at 29,200, OIL at 13,300 and PVD at 18,900. The adjustment lands after a stretch in which domestic pump prices rose through four consecutive September cycles and into early October, pressuring household budgets and the inflation outlook; the government responded with a September 30 resolution extending fuel tax cuts. Gasoline retail prices and diesel wholesale economics pull in opposite directions for the listed complex, with PLX most exposed to retail gasoline margins and BSR most exposed to diesel and crude spreads.

Strategic Significance

The split adjustment matters because it separates the margin story for retail from the margin story for refining. A gasoline cut compresses the retail spread PLX earns on its highest-volume product, while a diesel increase supports the middle-distillate yields that anchor BSR’s refining economics. The suspension of stabilization fund drawdowns removes a buffer that has historically smoothed retail margins, leaving PLX more directly exposed to global product price swings. The ministry’s emphasis on diesel security and 2026 minimum supply obligations signals continued policy attention to inventory and import planning, which affects working capital and storage costs across the wholesale chain.

What to Watch

• The next pricing cycle announcement from the Ministry of Industry and Trade, expected within roughly seven days.
• Global Brent and Singapore product cracks, particularly diesel, which drive the pass-through into the next adjustment.
• Any further extension or expiry of the fuel tax cuts granted under the September 30 resolution.
• PLX and BSR third-quarter earnings disclosures, which will show how retail and refining margins absorbed the September price run-up.
• Foreign-ownership and block-trade filings in PLX and BSR, given the sector’s sensitivity to global crude moves.
