Muangthai Capital Public Company LimitedFloods are expected to hit MTC's 2026 earnings by about 2%.
Bualuang Securities (BLS) said in an analysis that the flood situation has widened, covering 30 provinces and 191 districts in Bangkok as of 1 October 2026, affecting 1.18 million households and about 3.35 million people. The impact on the economy remains limited, however, if the situation does not drag on and does not hit core production bases. The Bank of Thailand estimates the effect on GDP at about 0.03–0.10%, while the research team expects the impact on GDP to be no more than 0.1% and on SET earnings no more than 2%, far below the major floods of 2011. The key thing to watch is the length of production stoppages in the industrial sector rather than the amount of flooded area. At AMATA City Chonburi, about 150 factories were affected and 34 temporarily halted production, while KCE and HANA have some production bases in Ayutthaya. As for DELTA's plants in Bang Pu and Wellgrow, no water entered the factories and operations have returned to normal. Other groups saw fairly limited impact. Consumer finance firms are expected to see about a 2% hit to 2026 earnings for TIDLOR and MTC and 1% for SAWAD, while banks face their main risk from higher provisioning, with an estimated 1–2% impact on earnings, larger than the effect on interest income. BGRIM said its SPP power plants in Amata City Chonburi and its floating solar operations are still running normally. Bualuang sees the flood-driven volatility as a chance to gradually accumulate stocks with resilient earnings and quick recovery prospects, namely CRC, AWC, CENTEL, BDMS, BH, GULF, GUNKUL, DELTA, KCE and HANA, which still have support from demand for AI and data centers.
