As of 1 Oct 2026, the Ministry of Industry reports 1,315 businesses affected across 40 provinces, including 1,179 SMEs. Thai Chamber of Commerce estimates 5 days of flooding caused 12,000 million baht in damage, and KResearch projects 7,000-17,000 million baht depending on how long it lasts. For cash-based SMEs, losing 1-3 days of sales can disrupt liquidity while rent, wages and ingredients still fall due. Plan now for a second upstream flood wave expected in early the following month: build a cash buffer, check supplier and delivery continuity, and protect staff safety first.
