Summary · why it matters

Four brokerages assess that the flood situation in Bangkok and its vicinity in 2026 will cause limited economic damage, as the waters have not yet spread into industrial estates or key production bases, unlike the great flood of 2011 that disrupted production chains on a wide scale. Finansia Syrus Securities estimates preliminary damage at around 20–40 billion baht, or roughly 0.1–0.2% of GDP, and views pressure on the stock market as reflecting short-term concerns rather than affecting earnings. Kasikorn Securities estimates damage at about 3,000–4,000 million baht per day, or roughly 20–30 billion baht per week; if severe conditions persist for one week, it could drag on GDP by about 0.1%. As of 27 September 2026, 25 provinces and 128 districts have been affected, with about 545,000 people impacted, compared with 2011 when floods hit 66 provinces, affected about 13.6 million people and caused damage of approximately 1.4 trillion baht. CGS International notes that Bangkok and its vicinity account for about 47.3% of the country's economy, and divides the situation into two scenarios: if water can be drained within 4–5 days, the impact will be limited, but if it drags on beyond 5 days, it could weigh more on purchasing power and consumption. For stocks that benefit after the waters recede, Finansia Syrus favours HMPRO, GLOBAL, DOHOME, TOA, SCGD, DCC and DRT, while Kasikorn favours retail and food groups as well as the ICT group. Pi Securities estimates a SET range of 1,590–1,620 points and picks BDMS, BCH, CPALL, PTT, PTTEP, PTTGC, TOP, ITC and TU, while CGS International says to watch DELTA, HANA and KCE if the SET falls below 1,600 points, on the theme of investment in artificial intelligence and digital infrastructure.
