For residents and long-term expats who cook at home in Vietnam, August brought a small rise in kitchen running costs. Under the August 1 price revision, the retail price of a 12kg household LPG cylinder rose to 552,000 dong (about 3,320 yen) in Ho Chi Minh City — up 30,000 dong (about 180 yen) per cylinder from the previous month. In Hanoi, too, the price climbed to 518,400 dong (about 3,110 yen), up 16,200 dong (about 100 yen). Unlike in Japan, where a bill arrives from the gas company every month, Vietnamese households feel this kind of price rise "each time they swap the cylinder." Here's a rundown of what the numbers mean and how the exchange system works.
Ho Chi Minh City at 552,000 dong — a gap of more than 30% between regions for a 12kg cylinder
Retail prices for household gas in Vietnam vary clearly by region and brand. After the August revision, the 12kg cylinder costs 552,000 dong (about 3,320 yen) in Ho Chi Minh City, the highest in the country, while Hanoi's Petrolimex is among the cheapest at 518,400 dong (about 3,110 yen). By brand, the gap runs to nearly 130,000 dong between the cheapest, Petrolimex at 518,400 dong, and the most expensive, Pacific Petro at 647,000 dong (about 3,880 yen), even for the same 12kg size.
According to the report, the gap between the highest-priced area, Ho Chi Minh City, and the cheapest region (Hai Phong) is 45,912 dong (about 280 yen) per cylinder. Even within the same country, annual gas costs can differ by several thousand yen depending on the city you live in and the cylinder brand.
| Region / brand (12kg) | August retail price | Approximate yen conversion |
|---|---|---|
| Ho Chi Minh City (highest nationwide) | 552,000 dong | About 3,320 yen |
| Hanoi Petrolimex (among the cheapest) | 518,400 dong | About 3,110 yen |
| Pacific Petro (highest by brand) | 647,000 dong | About 3,880 yen |
Not a bill but a "cylinder swap" — piped city gas barely exists
What first throws people newly arrived from Japan is that piped city gas is almost nonexistent in Vietnamese homes. Most houses and apartments cook by running a hose from a metal cylinder beside the kitchen to the stove. When the gas runs out, the whole cylinder is swapped for a full one. So there's little concept of "this month's gas bill" — a price hike instead hits all at once the next time the cylinder is replaced.
How long a 12kg cylinder lasts varies enormously depending on whether a household eats out mostly or cooks at home mostly. For a household of one or two people using the stove only once or twice a day, one cylinder lasting several months isn't unusual. A household that stir-fries and simmers dishes properly every day, on the other hand, burns through it faster. For a household that swaps cylinders infrequently, this 30,000 dong (about 180 yen) increase adds only a few tens of yen a month to the burden — not enough of an impact to warrant panic-buying.
Why it moves every month — the import price (CP) — August at $630/ton, up $40 from the previous month
Vietnam's household gas prices are revised on the 1st of every month because the country relies almost entirely on imports for its raw LPG. The benchmark import average price (CP) was set at $630 per ton in August, up $40 per ton from July. This rise in the international price is passed straight through to domestic retail prices, driving the increases seen in each region.
Put another way, gas prices move up and down every month in line with global LPG market rates. This time it's a rise, but when the CP falls, cylinder prices come back down just as readily the following month. Unlike Japan's gradual city-gas rate revisions, it helps to budget on the assumption that prices can swing by a few hundred yen from month to month. For those who cook at home, it's enough to give the monthly price-revision news a quick glance.
In a country where eating out is cheap, home-cooking gas costs are key to protecting your budget
Vietnam is a country where eating out is so cheap — a bowl of street-stall pho for around 80 yen — that cooking at home doesn't always save money. Even so, families and long-term residents tend to cook more, and cylinder costs become a real fixed expense. For a household that goes through one 552,000-dong cylinder every two to three months, gas costs roughly 1,000 to 1,800 yen a month. That's small compared to rent or electricity (utility bills of around $80 a month are typical in Ho Chi Minh City), but it adds up if prices keep climbing.
Fine-tuning the stove's flame, cutting simmering time with a pressure cooker, prepping ingredients in batches to reduce how often you light the stove — small habits like these stretch a cylinder further.

The practicalities of swapping cylinders — a phone call, a deposit, and the risk of fakes
The swap process itself is simple. Call the number on the sticker attached to the cylinder, or ask your apartment's building manager, and a new cylinder arrives by motorbike the same day, with the empty one taken away. In most cases, you pay a deposit for the cylinder itself the first time, and after that only pay for the contents. So what you pay each time is the "gas" portion that just went up in price — the deposit is refunded when you move out, for example.
One thing residents should watch for is cheap, unbranded cylinders that weren't properly refilled, or refills that fall short of the stated volume. It's safer to avoid extremely cheap door-to-door sellers and stick with the shop you've used since moving in, or a clearly branded supplier like Petrolimex. Deterioration of the regulator and hose can lead to fires, so it's also important not to keep using old equipment just because it's cheaper.

Summary
Under the August 1 revision, the 12kg household cylinder rose to 552,000 dong (about 3,320 yen, up 30,000 dong from the previous month) in Ho Chi Minh City and 518,400 dong (about 3,110 yen, up 16,200 dong) in Hanoi. The trigger was a $40 rise in the import CP price to $630 per ton. Because gas in Vietnam is paid for through cylinder swaps rather than a monthly bill, a price hike hits all at once at the next swap. For households that swap infrequently, the added monthly burden is only a few tens of yen — but budgeting on the assumption that prices move every month with the CP means you can take both hikes and drops in stride.
