We report results of a randomized control trial in which parents of primary school leavers were encouraged to open a convenient bank account operated over a mobile money platform. A lock savings account (LSA) was randomly promoted to half the treatment group. Treatment boosted account take-up by 25 percentage points. Intent-to-treat estimates show that being offered either account increased savings on the mobile phone. Total financial savings increased by 3-4 times, suggesting access to the mobile bank account crowded in other forms of savings. High school enrollment was 5-6 percentage points higher – representing a one third increase for compliers.
