The current study investigated the association between psychological factors and financial behaviour during the COVID-19 pandemic in older people. Older people were chosen compared to other age groups because of the relatively greater impact in this age group of suboptimal financial decisions on future financial wellbeing. We hypothesised that the psychological factors facilitating general wellbeing during the COVID-I9 pandemic, i.e., positive mental wellbeing, hope, and positive coping, will have positive effects on financial behaviour. Based on telephone interviews, 1501 older Australians (Men = 750 and Women = 751; 55-64y = 630; > 65y = 871) completed an omnibus questionnaire examining coping, hope, mental wellbeing, and financial behaviour. Data was analysed using logistic regression and an ordinary and two-stage least square frameworks. Analyses revealed that the psychological factors identified as facilitating general wellbeing during the COVID-I9 pandemic also facilitated positive financial behaviour with hope and mental wellbeing emerging as significant determinants. Based on weightings from principal component analysis, one item each from the hope and mental wellbeing scale with eigenvalues > 1 were found to be robust predictors of positive financial behaviours. In conclusion, the findings support the assumption that the psychological factors associated with general wellbeing during the COVID-19 pandemic are also associated with positive financial behaviour. They further raise the possibility that single hope and positive mental well-being items can also be used to monitor psychological health and predict financial behaviour in older people and, in particular, at times of crisis. The latter may be useful measures for government to monitor psychological and financial wellbeing and inform policy for supporting older people at times of crisis.
