Digital traps: The compounding impact of BNPL and social media on consumer financial stress

This study investigates the impact of Buy Now, Pay Later (BNPL) usage, social media exposure, and their interaction on consumer financial stress, using a large, nationally representative dataset of U.S. households. Financial stress is measured by self-reported financial insecurity, credit card debt, and the use of check-cashing services. To address endogeneity and strengthen causal inference, the study employs a triangulated identification strategy that combines Propensity Score Matching, Doubly Robust Estimation, Extended Regression Models, and Conditional Mixed Process estimation. Across all methods, BNPL and social media independently exacerbate financial stress, while their joint exposure—conceptualized as digital co-exposure—compounds these effects, particularly by increasing unsecured debt and reliance on alternative financial services. For example, the propensity score matching results indicate that joint exposure to BNPL use and social media increases financial insecurity by approximately 0.34 points and unsecured debt by about 1.46 points, relative to comparable non-users. These findings support a behavioral amplification mechanism in which algorithmic targeting and frictionless credit access jointly erode financial self-regulation. For financial practitioners, the results underscore the importance of integrating behavioral and digital indicators into risk models, especially when assessing younger or financially vulnerable consumers. The study also informs regulatory and design interventions, including mandatory BNPL credit reporting, algorithmic transparency, and the use of digital nudges to mitigate impulsive spending. As fintech and social media ecosystems increasingly converge, understanding their interactive influence is essential for promoting consumer financial resilience.
