The covid-19 pandemic has had a very high impact on student monthly expenses. This is indicated by a decrease in the amount of pocket money, changes in the source of pocket money income, and a significant change in student spending. This study investigates the effect of family financial socialization on financial behaviour mediated by self-efficacy. The survey was conducted online to 157 private and public undergraduate and postgraduate students in Indonesia including questions about demographics, Family financial socialization, Financial Behaviour, and Self-efficacy. The research model consists of three hypotheses which are tested using structural equation modelling. The results show that family financial socialization has a positive effect on financial behaviour directly. Family financial socialization has a positive effect on financial behaviour indirectly through self-efficacy.
