The World Bank on Tuesday, 6 October 2026 lowered Nepal's economic growth projection to 3.7 per cent for fiscal year 2026-27, down from its earlier forecast of 4.2 per cent, citing the severe disruption caused by the August 2026 floods. The revision reflects what the global development lender described as a 'material negative impact' on the Himalayan nation's near-term economic prospects.

Four Transmission Channels Driving the Slowdown

In its report titled Nepal Development Update: Building Back Differently for the Future, the World Bank identified four primary channels through which the floods are expected to weigh on the economy: energy, transportation, trade, and tourism. Agriculture and the banking and insurance sectors were also flagged as affected channels, though with comparatively lower potential impact.

The bank said industry is expected to be the main drag on growth, given extensive damage to hydropower generation, solar energy assets, electricity transmission infrastructure, and transport networks. These disruptions, it warned, will constrain electricity production and impede the movement of goods across the country.

Hydropower Takes the Hardest Hit

Energy — and hydropower in particular — emerged as the most critical transmission channel in the bank's assessment. The floods affected 12 hydropower projects in total: seven operational projects with a combined capacity of 256.1 MW and five projects under construction with a combined capacity of 395.02 MW, along with a 25 MW solar facility.

Damage to transmission infrastructure disrupted a further 149.6 MW, bringing total affected generation and transmission capacity to approximately 430.7 MW — equivalent to 10.6 per cent of Nepal's installed hydropower and solar capacity for FY26. The World Bank pointed to the 111 MW Rasuwagadhi Hydropower Project as a cautionary case: it took nearly a year to fully restore generation after it was severely damaged by the 8 July 2025 Bhotekoshi flood — and the same project has been badly affected once again by the August 2026 floods.

'This illustrates the potential for flood-related damage to disrupt electricity supply and impose substantial reconstruction costs,' the bank said. It also noted that hydropower construction in unaffected areas is expected to continue, though projects could face higher insurance premiums, financing reassessments, and cost overruns.

Human and Economic Toll

The human cost has been devastating. According to the National Disaster Risk Reduction and Management Authority, 1,455 people have been confirmed dead and 5,285 remain missing following the disaster, which destroyed communities and infrastructure along the Bhotekoshi and Trishuli river corridors.

A Rapid Disaster Needs Assessment (RDNA) prepared jointly by the National Planning Commission and the disaster authority estimates physical damage at 274.48 billion Nepali rupees (approximately US$ 1.93 billion), with total losses and damages reaching 408.28 billion rupees (approximately US$ 2.87 billion). Preliminary assessments indicate that more than 723 billion rupees will be required for reconstruction and recovery of affected infrastructure and assets. The Nepali government is now working on a more comprehensive Post-Disaster Needs Assessment.

Tourism and Trade: A Prolonged Disruption

Tourism is expected to face a potentially prolonged impact, reflecting both physical disruptions and heightened perceptions of travel risk. More than 200 hotels and restaurants were damaged across affected districts, while access to major trekking and pilgrimage destinations — including Langtang, Gosaikunda, and the Kailash Mansarovar corridor — has been disrupted.

Transportation and trade are also significant transmission channels, given Nepal's heavy dependence on a limited number of international and domestic trade corridors. Services more broadly are expected to be affected through disruptions to trade, transport, tourism, and financial activity, the bank said, while agricultural losses — though limited in their effect on aggregate output — are expected to have significant impacts on livelihoods in affected areas.

Recovery Expected From FY2027-28 Onwards

Despite the bleak near-term outlook, the World Bank said economic activity is expected to gradually recover in fiscal year 2027-28 as reconstruction gains momentum and damaged infrastructure is progressively restored. The pace of that recovery will hinge on how swiftly Nepal can mobilise reconstruction financing and address the structural vulnerabilities that made its hydropower and transport networks so exposed to repeat flood events.
