When Bank Entry Rules Shape Who Gets an Account

A change in where banks could open branches reached beyond the banking industry: more low-income households obtained accounts. In their 2019 study, Bank-Branch Supply, Financial Inclusion, and Wealth Accumulation, Claire Célérier and Adrien Matray estimated that fully lifting interstate branching restrictions increased account ownership by about four percentage points.
The researchers exploited differences in how US states relaxed entry barriers after a 1994 federal law. They combined bank branch records with household survey data from 1993–2005, focusing on households earning less than twice the poverty threshold. They compared changes within states against states in the same region whose rules had not changed, while accounting for household characteristics and economic conditions.
Branch density rose by roughly 20% in poor counties after full deregulation. Account ownership also increased. This combination suggests that remaining outside banking partly reflected limits on available services. Shorter distances and more affordable accounts are possible explanations, but the study does not establish their separate contributions.
To investigate wealth, the authors used account ownership predicted by deregulation, rather than treating the ordinary wealth gap between banked and unbanked households as causal. Their estimate indicated about $5,752 more net worth excluding housing, measured in 2000 dollars. Vehicles and interest-bearing balances were important components of the asset gains; borrowing also increased.
The causal interpretation depends on deregulation affecting wealth through financial inclusion, without a separate direct pathway. Tests found no measurable income or employment changes, and credit unions unaffected by the law showed no comparable branch expansion. These checks support that assumption without proving it. The wealth analysis also used repeated cross-sections rather than tracking each household’s accumulation over time.
The estimates apply to households whose account ownership responded to these historical reforms, not automatically to every household. For market-access policy, the useful lesson is that rules governing provider entry can affect participation and household balance sheets. More accounts alone do not guarantee the same benefits elsewhere.
