Vietnam Fuel Price Drops Record 5,625 VND/L on March 27

Starting at midnight on March 27, 2026, Vietnamese fuel prices saw their sharpest single-session decline in over a decade. RON 95-III — the most commonly used gasoline — plunged 5,625 VND per liter, falling from 29,957 VND to 24,332 VND per liter. E5 RON 92, the ethanol-blended alternative, dropped 4,749 VND per liter to settle at 23,326 VND. Diesel 0.05S, which powers most commercial transport, fell 2,459 VND per liter to 35,440 VND. These cuts are not driven by a collapse in global oil prices — in fact, crude oil has been rising. Instead, the reductions are entirely the result of a government fiscal intervention: the simultaneous elimination of three separate taxes that typically account for 15-20% of the retail fuel price.

On March 26, 2026, Prime Minister Pham Minh Chinh signed Decision 482/QD-TTg — an emergency fiscal measure that simultaneously reduces three fuel-related taxes to zero percent. This is unprecedented: previous interventions targeted only one tax at a time. The three taxes eliminated: • Environmental protection tax (Thuế BVMT): Previously 2,000-4,000 VND/liter depending on fuel type. Now 0. • Special consumption tax (Thuế TTĐB): Previously 10% of base price for RON 95. Now 0. • Value-added tax (VAT): Previously 8% of pre-tax retail price. Now 0. The measure takes effect at 00:00 on March 27 and remains in force through April 15, 2026 — a 20-day window. The government will review conditions before deciding whether to extend, partially restore, or fully reinstate these taxes.

The paradox of this fuel price cut is that global crude oil is not falling — it is rising. Brent crude climbed 6% in March 2026, driven primarily by escalating tensions between Iran and the United States around the Strait of Hormuz. The strait handles roughly 20% of the world's oil trade, and any disruption there sends prices surging. Vietnam imports approximately 70% of its refined fuel. Without government intervention, domestic prices would have increased significantly this cycle. The fuel price stabilization fund — the traditional buffer — has been drawn down to roughly 320 billion VND, far too thin to absorb the full shock. Facing the prospect of fuel prices breaching the psychologically important 30,000 VND/liter threshold for RON 95, the Prime Minister opted for the nuclear option: zeroing out all three applicable taxes at once. This is a fiscal sacrifice — estimated to cost the government 3,000-4,000 billion VND over the 20-day period in lost tax revenue.

The Strait of Hormuz — a narrow waterway between Iran and Oman — is the world's most critical oil chokepoint. Roughly 21 million barrels of oil pass through it daily, accounting for about 20% of global petroleum trade. In March 2026, repeated naval confrontations between Iranian Revolutionary Guard vessels and US Navy escorts have rattled markets. Brent crude has climbed from around $78 to nearly $83 per barrel over the month — a 6% increase. Analysts warn that any actual disruption to tanker traffic could push prices above $100, which would create severe downstream effects for oil-importing nations like Vietnam. For Vietnamese consumers, this means the current low fuel prices are entirely policy-driven, not market-driven. If the government lifts the tax exemption in mid-April while Hormuz tensions persist, a sharp price rebound is virtually certain.
