The estimate, included in the World Bank’s Nepal Development Update unveiled this week, is close to the Nepal government’s preliminary Rapid Damage and Needs Assessment (RDNA), which put physical damage at US$1.81 billion. The government’s assessment also estimated losses beyond physical assets at US$883.32 million, taking the total economic effects of the disaster to approximately US$2.7 billion. The World Bank’s Global Rapid Post-Disaster Damage Estimation (GRADE) found that infrastructure suffered the greatest damage, estimated at US$1.38 billion, or 83 per cent of the total. Residential buildings accounted for US$185 million, or 11 per cent, while non-residential buildings sustained damage worth US$101 million, or 6 per cent. The floods along the Bhotekoshi and Trishuli rivers caused extensive damage to hydropower projects, solar energy facilities, electricity transmission infrastructure and transport networks. The energy sector, particularly hydropower, was among the worst affected. The August 2026 floods affected 12 hydropower projects and one solar project, involving 281.1 MW of operational capacity and 395.02 MW of capacity under construction. Damage to transmission lines and substations also disrupted the transmission of 149.6 MW of electricity to the national grid. The total affected capacity reached approximately 430.7 MW, equivalent to 10.6 per cent of Nepal’s installed hydropower and solar capacity at the end of fiscal year 2025-26, which concluded in mid-July. The disaster also severely damaged transport infrastructure along the 82-km Rasuwa trade corridor, which connects Kathmandu with the Rasuwagadhi border point with China. More than 55 km of the corridor was damaged, including 40 km that was completely destroyed. The floods also damaged 37 motorable bridges and 68 suspension bridges. The disaster resulted in significant human losses along the affected corridor and beyond. According to Nepal’s National Disaster Risk Reduction and Management Authority, 1,455 people had been confirmed dead, while 5,285 remained missing following the disaster. The World Bank report found that the physical damage was concentrated in three districts in central Nepal: Rasuwa, Nuwakot and Dhading. Rasuwa was the worst-affected district, accounting for US$1.07 billion, or 64 per cent, of the total direct damage. Nuwakot recorded an estimated US$551 million in damage, while Dhading suffered approximately US$39 million. “The findings highlight the concentration of physical damage in a small number of districts and the disproportionate impact on infrastructure, underscoring the scale of the reconstruction challenge facing the affected areas,” the World Bank said. The global development financier said the floods had demonstrated the scale and complexity of disaster risks in Nepal’s Himalayan environment. The event also showed how a single extreme weather event could trigger cascading impacts across sectors and geographical areas. The report said recovery efforts should extend beyond restoring infrastructure to its pre-disaster condition. While the principle of “Build Back Better” remained relevant, the World Bank stressed that rebuilding infrastructure to higher engineering standards in the same locations might not always be sufficient. “In some cases, simply rebuilding the same infrastructure in the same location to a higher engineering standard may not be sufficient. Nepal may need to build differently — based on a better understanding of risk, more careful decisions about location and design, greater redundancy in critical networks, stronger monitoring and early warning, and a more integrated approach to infrastructure development in the Himalayas,” the report said. The World Bank said Nepal’s recovery strategy should incorporate improved risk assessment, more informed infrastructure planning, stronger monitoring systems and better early warning mechanisms. The report emphasised that reconstruction should not only restore damaged assets but also reduce the impact of future disasters, particularly in the country’s vulnerable Himalayan regions.
