Thailand's October 2026 Inflation Hits 3.90% as Fuel Prices Jump 29.18%

Fuel and food push household costs higher

Thailand's annual headline inflation reached 3.90% in October 2026 as fuel prices climbed 29.18%, putting pressure on household travel, public transport and everyday meals. Diesel cost 42.70 baht a litre, compared with 31.35 baht a year earlier, while food and non-alcoholic beverage prices rose 4.26%.

Nuntapong Jiralertpong, director of the Commerce Ministry's Trade Policy and Strategy Office, said the consumer price index reached 103.90 in October, increasing 0.94% from September. Annual inflation accelerated from September's 2.82%, a rise of 1.08 percentage points in one month.

The ministry kept its forecast for average inflation in 2026 at 1.8% to 2.2%, with a midpoint of 2.0%. Average headline inflation for January through October was 1.77% compared with the same period in 2025. November inflation was expected to remain positive.

The figures show why families can face sharply higher bills even when the annual average remains relatively moderate. Fuel, eggs, prepared meals and several transport services became more expensive, while electricity, some household goods and personal care products became cheaper.

What the inflation figures mean

Headline inflation measures how the price of a basket of consumer goods and services changes over time. October's 3.90% annual rate means that the basket cost 3.90% more than in October 2025. The monthly increase of 0.94% compares October with September 2026.

Core inflation, which leaves out fresh food and energy, stood at 1.58%. Those categories are excluded because their prices can move sharply with weather, harvests and international energy markets. The gap between headline and core inflation shows how strongly those volatile costs affected October's reading.

A household's experience depends on what it buys. A family spending heavily on fuel and prepared meals would face a different change in expenses from one buying discounted appliances or paying a lower electricity bill.

Diesel shows the size of the energy shock

October's fuel increases reflected continuing pressure from the Middle East energy crisis following attacks on Saudi Arabian oil producing areas. Average Dubai crude prices reached their highest level in seven months, raising the cost of an important input for transport and distribution.

The ministry's fuel figures show how much prices changed from October 2025:

• Diesel rose to 42.70 baht a litre from 31.35 baht, an increase of 11.35 baht, or about 36.2%.
• Gasohol 95 rose to 41.47 baht a litre from 32.27 baht, an increase of 9.20 baht, or about 28.5%.
• Gasohol 91 rose to 40.92 baht a litre from 31.68 baht, an increase of 9.24 baht, or about 29.2%.

For someone purchasing 50 litres of diesel, those prices translate into a bill of 2,135 baht, compared with 1,567.50 baht a year earlier. The difference is 567.50 baht for the same quantity of fuel.

Relatively low fuel prices a year earlier also made October's annual increase larger. An annual inflation calculation compares two price levels, so the starting price matters alongside the current one.

Transport fares extend the pressure beyond drivers

Prices in the vehicles, transport and communications category rose 10.93% from a year earlier. Increases covered fuel and several services used for commuting, school journeys and travel between provinces.

School transport, interprovincial vans, air-conditioned buses, motorcycle taxis and minibuses became more expensive. Prices also increased for songthaews, the shared pickup taxis used on many local routes. Households without a private vehicle therefore faced some of the same transport pressures as motorists.

The broader category covering goods and services other than food and beverages increased 3.66%. Within it, recreation, reading, education and religious activities rose 1.51%, with increases for domestic and overseas tours, travel to visit relatives or make merit, and pet food. Tobacco and alcoholic beverages edged up 0.04%, including increases for beer and wine.

Food bills rise as flooding eases

Food and non-alcoholic beverage prices increased 4.26% from October 2025. Flooding in major vegetable growing areas pushed up some fresh vegetable prices early in the month, although prices gradually moved back towards normal by the end of October as disruption eased.

Limes, holy basil, Chinese kale, aubergines, spring onions, yardlong beans and Chinese flowering cabbage were among the vegetables that became more expensive. Pork, fresh chicken, fresh and steamed mackerel, whiteleg shrimp and squid also rose in price.

Prepared food prices increased 4.06%. The rises affected ready-made dishes, noodles, rice with curry, rice with holy basil stir-fries and fried rice. These are routine purchases for many workers and students, making the increase relevant to daily spending as well as grocery budgets.

Eggs and dairy products recorded a larger increase of 6.90%, including higher prices for chicken and duck eggs, soya milk and fermented milk drinks. White rice, glutinous rice and sandwich bread also became more expensive.

Non-alcoholic beverages rose 1.94%, including purified drinking water, soft drinks, instant coffee, and hot and iced coffee. Other increases covered sweets, ice cream, brown sugar, fish sauce, shrimp paste, vegetable oil, monosodium glutamate, seasonings and soy sauce.

Lower electricity and goods prices offer some relief

Electricity prices declined, helping to offset part of the increase elsewhere in household budgets. Charges for contracted home repairs covering labour and materials also fell.

Several household items became cheaper, including bedsheets, blankets, towels, bathroom and floor cleaners, washing machines and air conditioners. Personal care price declines covered skin protection and skincare products, hair conditioner, perfume, soap, face powder, facial cleansers and toothpaste.

Clothing and footwear prices also fell for selected products, including men's and women's shirts and trousers, men's trainers and children's T-shirts. Fresh fruit prices declined 0.15%, with lower prices for longkong, mangoes, dragon fruit and Nam Wa bananas.

The timing of purchases matters for household relief. Lower electricity charges can affect a recurring bill, while cheaper washing machines or air conditioners mainly help families buying those appliances. Higher food and transport costs reach budgets through frequent purchases.

Households seek energy relief and income support

A nationwide survey of 5,553 people conducted from October 5 to 26 found demand for measures to reduce everyday expenses, especially fuel and electricity costs. Respondents also wanted government co-payment measures, support for employment and help to increase income.

Co-payment measures divide an eligible purchase between the consumer and the government. They can reduce what a household pays at the checkout, while employment and income support address how much money people have available to spend.

The Commerce Ministry's Thai Chuai Thai and Thong Fah programmes included 3,036 outlets selling goods at reduced prices for 90 days. Cooperation with 27 private firms covered discounts on 4,223 goods and services during October and November, with reductions of up to 78%.

The ministry also assigned commerce offices in all 76 provinces to monitor prices and keep supplies sufficient for demand. Its monitoring covered energy costs, transport charges and goods prices. The advertised maximum discount applied to selected purchases; the amount saved by each household would depend on the products it bought.

How Thailand compares with its neighbours

September figures, the latest international comparison cited by the ministry, placed Thailand's headline inflation rate of 2.82% as the 37th lowest among 139 reporting economies. Thailand ranked fifth lowest among the 10 ASEAN economies included.

Thailand's September rate was below those of Indonesia, Vietnam, Cambodia, the Philippines and Laos. October's domestic reading of 3.90% came later, so the international ranking describes conditions before the latest acceleration.

The sequence of figures and measures helps put the October result in context:

• September 2026: Annual headline inflation stood at 2.82%, the rate used in the international comparison.
• October 5 to 26: A survey of 5,553 people gathered views on living costs and government support.
• October 2026: Annual headline inflation reached 3.90%, while prices increased 0.94% from September.
• October and November 2026: Discounts involving 27 private firms covered 4,223 goods and services.
• November 2026: The ministry expected annual inflation to remain positive.

Why the annual forecast remains at 2.0%

The Commerce Ministry retained its forecast range of 1.8% to 2.2% for average headline inflation across 2026. October's 3.90% reading sits above that range, but the annual forecast covers price changes across the whole year rather than a single month.

The January to October average of 1.77% helps explain the difference. Earlier months carry weight in the annual result, so a sharp increase late in the year can coexist with a lower annual average.

Global energy prices, prepared food costs, transport charges and weather affecting agricultural production were the main risks identified for November. Government energy measures, the ministry's price monitoring and easing floods were expected to reduce pressure on household costs.

The ministry gave no numerical forecast for November in its assessment. Its expectation that inflation would remain positive means prices were expected to stay above their level a year earlier. The size of that increase would depend in part on energy costs and the continued recovery of agricultural supplies.
