Bringing together insights from feminist political economy and everyday financialization, this paper explores the complex nature of women’s pension decisions. Women in the UK experience structural constraints originating from a pension system which ignores socially reproductive activities, and they face limitations in pension planning due to prevalent gender norms. Both aspects have a significant impact on women’s long-term financial wellbeing and yet little attention has been paid to how they operate within these constraints, ultimately leading to women’s behaviors being construed as passive or irrational. Drawing on 61 interviews, our paper conceptualizes pension practices adopted by women through gendered finance rationality, defined as variegated financial practices shaped by the gendered context in which they arise. Rather than being irrational or passive victims of an unequal welfare system, women actively engage with the limitations of the pension system and seek out asset strategies which seem more suited to their life trajectories, but implicitly reinforce gendered wealth inequalities.
