The Bank of Thailand has warned that recurring economic shocks are eroding the financial resilience of households and small businesses, raising concerns that recent flooding could cause lasting damage. Officials noted that vulnerable borrowers’ balance sheets have weakened, with estimated nationwide losses ranging from 16.9 billion to 33.8 billion baht, including significant impacts in Bangkok.
Flooding has disrupted transport, retail, construction, manufacturing, and tourism, with Toyota plants suspending operations and Bangkok hotels reporting cancellations during Golden Week. Daily wage earners and small firms face cash-flow pressures as fixed costs continue despite lost income. The central bank is urging lenders to offer payment relief and liquidity support, while monitoring consumer spending and fiscal pressures amid rising public debt.
The Bank of Thailand has recently warned that repeated economic shocks are weakening the financial position of households and small businesses, increasing the risk that the country’s latest floods will cause damage long after the water recedes.
Chayawadee Chai-Anant, assistant governor for corporate relations and a spokesperson for the central bank, said successive shocks had already weakened the balance sheets of vulnerable borrowers. “Small businesses and vulnerable groups could face a heavier debt burden,” she said during an official briefing to reporters on behalf of the BOT. Also, added:
“Successive economic shocks are weakening their balance sheets. That is quite worrying.”
The warning comes as flooding disrupts activity across several major sectors and economists estimate nationwide losses of between 16.9 billion baht and 33.8 billion baht. The central estimate includes damage and lost activity in Bangkok, where losses have been placed at approximately 10.6 billion baht, as reported.
Flood disruption spreads across sectors
The flooding has affected transport, services, retail, wholesale, construction and goods distribution. Manufacturing initially escaped much of the disruption, but supply-chain problems later forced four Toyota plants to suspend operations.
The impact on tourism is also becoming visible. Bangkok hotels have recorded cancellations and postponed reservations during China’s National Day Golden Week, which began on October 1.
Thienprasit Chaiyapatranun, president of the Thai Hotels Association, said the group was surveying members to determine the scale of the cancellations. The association expects Bangkok hotel occupancy to decline by less than 10% year on year during September and October.
The disruption is concentrated in parts of eastern Bangkok, including Bang Kapi, Ramkhamhaeng, Srinakarin and On Nut. Several areas of neighbouring Samut Prakan have also been affected.
Most major hotels remain open, and the city’s two main airports continue to operate. Major roads, including Vibhavadi Rangsit Road and Bangkok’s motorway network, remain accessible. The Thai Hotels Association estimates that around 30% to 40% of Bangkok has been affected, leaving large parts of the capital functioning normally.
The distinction matters for the tourism industry. Travellers may change their plans after seeing images of flooded roads even when their hotels, airports and intended destinations remain accessible. Reservations can be cancelled or postponed only a few days before arrival, leaving operators exposed while the situation remains uncertain.
The Association of Thai Travel Agents expects Bangkok tourism to feel the impact for roughly 10 days and has warned that some international visitors could choose alternative destinations.
Households and small firms face deeper pressure
Flood damage is arriving after a period of weak growth and financial strain. Daily wage earners can lose income as soon as roads become impassable or businesses close. Rent, loan repayments and other fixed costs continue during the interruption.
Small companies face a similar imbalance. Sales may disappear while wages, debt payments and operating expenses remain due. A short closure can therefore create a cash-flow problem even when a business suffers little direct physical damage.
Bangkok and its surrounding provinces account for approximately half of Thailand’s economic output. The financial pressure created by disruption can therefore spread through the national economy, especially when highly indebted households reduce spending and small firms postpone investment.
Kasikorn Research Centre has estimated losses of between 7 billion baht and 17 billion baht if disruption lasts three to seven days. A longer period of flooding, further manufacturing stoppages or additional logistics problems could push the total higher.
The different estimates reflect the uncertainty surrounding the crisis. Flooding remains active across several areas, while the eventual cost will depend on how quickly businesses reopen and how much production, tourism and consumer activity recover.
BOT calls for lender support
The Bank of Thailand is encouraging financial institutions to assist borrowers affected by the floods. Possible measures include temporary principal and interest payment holidays, lower monthly instalments and additional liquidity for small and medium-sized businesses.
These measures could prevent a temporary loss of income from turning into a broader credit problem. They will be particularly important for companies that need working capital to replace stock, repair equipment or pay employees during a period of reduced revenue.
The central bank is also monitoring household purchasing power and tourism confidence as Thailand approaches the final months of 2026. Any prolonged reduction in consumer spending could extend the economic damage beyond the directly flooded areas.
Public finances face additional pressure as well. Flood relief and reconstruction will require government spending at a time when public debt is approaching the statutory ceiling of 70% of GDP. Repeated disasters could increase the fiscal cost of repairing infrastructure while the country also faces long-term spending pressures linked to an ageing population.
For now, the duration of the disruption remains the most important variable. A rapid improvement in weather would allow transport networks to reopen and businesses to resume operations. Continued rainfall would increase the risk of broader supply-chain interruptions and deeper losses.
The Bank of Thailand’s concern reaches beyond flooded streets and damaged property. Each additional shock reduces the financial room available to households and businesses. Thailand’s recovery will depend on how quickly economic activity resumes, and on whether vulnerable borrowers can survive the disruption without taking on unsustainable debt.
