We use country-wide data on all electronic payments in point-of-sale (POS) and online terminals of Iran to study the change in the pattern of consumption and online-offline substitution during the COVID-19 lockdown and after the relaxation of restrictions in May and June. Using a difference-in-difference approach, we find that during the strictest lockdown month, growth in value of transactions dropped by 41% compared to the benchmark month before the pandemic. After lifting the lockdown, the growth rose by 12% above the benchmark month.
