Vietnam fuel prices on 31 July 2026 see E10 falling almost 9,000 VND per litre and RON 92 approaching a fresh low, with detailed retail and tank‑fill costs for

E10 gasoline fell by roughly 9,000 VND per litre on 31 July 2026, pushing the price of RON 92 toward a new trough and reshaping cost calculations for the country’s most common mopeds. The move matters for commuters and small‑business owners who rely on low‑displacement motorcycles for daily travel.

| At a glance | |
|---|---|
| Price change | E10 down ~9,000 VND/litre |
| Current price | RON 92 at 22,388 VND/litre (Vùng 2) |
| Recent low | RON 92 7,722 VND below its 30,110 VND peak (24 Mar) |
| Catalyst | Global crude oil fell ~3% (≈1 USD/barrel) after Hormuz tensions eased |

## Price dynamics and recent trends  
The Ministry of Industry and Trade‑Finance’s third consecutive price hike on 30 July 2026 raised E10, RON 92 and diesel, but the adjustment held only until the afternoon of 31 July, when E10’s retail price slipped by nearly 9,000 VND per litre [1]. This drop follows a sharp 3% decline in world crude oil prices on 30‑31 July, driven by the easing of supply‑chain stress in the Hormuz Strait. Domestically, the earlier price increase was intended to offset the high purchase cost of crude in the prior week, but the subsequent global price retreat allowed retailers to lower pump prices.

RON 92 now trades at 22,388 VND/litre in the second pricing zone, a level 7,722 VND beneath its 30,110 VND peak recorded on 24 March [1]. Similarly, E10 (RON 95) sits 8,561 VND below its historic high of 31,420 VND on the same date. Diesel, which peaked at 44,780 VND/litre on 3 April, is now 17,138 VND lower [1]. These margins illustrate how quickly Vietnamese fuel prices can swing in response to global oil movements.

## Impact on mopeds and tank‑fill costs  
The price shift directly affects the cost to fill the fuel tanks of the nation’s most popular 110‑125 cc mopeds. For example, a Honda Wave Alpha (3.7 L tank) requires about 82,806 VND to fill with E5 RON 92, while the same tank filled with E10 RON 95 costs roughly 84,545 VND [1]. Larger models such as the CFMoto CT125 (5.4 L) see tank‑fill costs of 120,852 VND (E5) and 123,390 VND (E10). The modest price differential—often under 2,000 VND per full tank—means riders can choose fuel type based on engine technology: older carbureted bikes benefit from the cheaper E5, whereas newer FI‑equipped models gain longevity from the cleaner-burning E10 [1].

## What to watch  
- **Crude oil price trend:** A further decline in global crude could deepen domestic fuel price cuts, while any resurgence (e.g., renewed geopolitical tension) may trigger another domestic hike.  
- **Regulatory adjustments:** The Ministry’s decision not to allocate a price‑stabilisation fund in the latest cycle suggests future price moves will rely more on market dynamics than subsidies.  
- **Moped fuel‑type adoption:** Monitoring sales of FI‑equipped versus carbureted mopeds will indicate whether price differentials influence consumer fuel‑type preferences.

The sharp E10 reduction underscores how tightly Vietnamese fuel prices track international oil markets, and it highlights the cost sensitivity of the country’s dominant mopeds. Future price paths will hinge on both global crude developments and domestic policy choices.
