The Office of Trade Policy and Strategy (สนค.) reports average Thai household spending of 21,217 baht/month for Jan–Sep 2026, up 326 baht year on year. Transport, freight and communication rose most (+228 baht), driven by fuel and public transport fares. Food rose 118 baht, mainly ready-to-eat meals. Households are cutting non-essentials such as clothing and health services to protect cash flow. SND expects costs to stay high through year-end, with fuel price volatility, holiday travel and flood effects on fresh vegetable prices as risks. For a shop, expect customers to trim discretionary spending, and check fuel and delivery costs in your pricing.
