Micro-entrepreneurs in South and Southeast Asia operate with thin margins and limited buffers, which leaves them exposed to economic shocks such as inflation, currency depreciation, supply disruption and political instability. Mobile financial services (MFS) have expanded rapidly in the region and are frequently promoted as a means of strengthening the capacity of small businesses to withstand such shocks. Using survey data from 640 micro-entrepreneurs, this paper compares how MFS contribute to business resilience during economic shocks in Bangladesh and Myanmar, two countries with contrasting MFS ecosystems and shock experiences. Data were collected through structured interviews in Dhaka, Chattogram, Yangon and Mandalay between September and December 2025 and analysed using ordinary least squares regression with a composite resilience index as the dependent variable and indicators of MFS use as the main predictors. The results show that MFS use is positively associated with resilience in both countries. Access to digital savings and micro-insurance shows the strongest resilience effect, exceeding the effects of mobile payments and digital credit, and this pattern holds in both samples. The association between digital credit and resilience is positive in Bangladesh but not statistically significant in Myanmar, where credit access contracted after 2021. The paper argues that policies promoting MFS for small business resilience should prioritise savings and insurance products rather than payments alone, and that provider strategies should be adapted to the regulatory and macroeconomic conditions of each country.
