The World Bank has estimated 1,425 billion baht (US$ 45.7 Bn) in economic damages and losses due to flooding, as of 1 December 2011. Most of this was to the manufacturing industry, as seven major industrial estates were inundated by as much 3 meters (10 feet) during the floods. Disruptions to manufacturing supply chains affected regional automobile production and caused a global shortage of hard disk drives which lasted throughout 2012.
The World Bank's estimate for this disaster means it ranks as the world's fourth costliest disaster as of 2011 surpassed only by the 2011 earthquake and tsunami in Japan, 1995 Kobe earthquake, and Hurricane Katrina in 2005.
Thailand's southern provinces also saw seasonal flash-flooding towards the end of the year, although these did not occur in the same extreme nature as in the more Northern provinces.
