Using a comprehensive dataset of 272 large-scale natural disasters in 83 countries from 1986 to 2018, we find that disasters increase government debt financing costs (T-bill rates and 10-year government bond yields) but only in the middle- and low-income countries. This distinct response relative to high-income countries is due to lower levels of credit market depth, of private insurance penetration, and of central bank independence.
The results for all natural disasters are driven by biological (epidemic) and climatological disasters - two types of hazards, the frequency and severity of which have been rising.
