Most US children keep cash outside banks, study finds

Hyperlayer has released research showing that most American children keep their money outside the traditional banking system. The study estimates that US children hold about $30 billion.

The findings focus on Generation Alpha, defined as children aged eight to 15, and suggest a large share of youth money sits in cash, fintech apps, or parent-managed accounts rather than bank accounts. According to the study, 72% of US children keep money outside traditional banking channels.

The report is based on a YouGov survey of 1,523 children in the United States, alongside parent focus groups. Hyperlayer said the wider international study also covered the UK and Hong Kong, but the US results highlight the scale of money children are already earning, saving, and spending before many form a direct relationship with a bank or credit union.

That market has attracted growing interest from financial groups and consumer finance apps. Cash App has expanded into banking for children as young as six, Chase offers an account for six-to-17-year-olds, and US Bank gives checking customers access to a co-branded Greenlight card for children. In another sign of competition for younger customers, Beast Industries acquired teen banking app Step.

Confidence gap

Beyond spending patterns, the research found a sharp shift in how children view their financial future as they move through their early teens. Among 14-year-olds, 37% said they expected to be rich as adults, but that figure fell to 16% among 15-year-olds.

The study also found that views on wealth grow more cautious with age. By 15, more than half of respondents defined being rich as "not having to worry about money", compared with about a third of eight-year-olds.

The findings suggest children are taking on more responsibility for money while reassessing what financial security means. They also indicate that money habits may form well before many young people receive mainstream banking products in their own name.

Rob Rooney, Co-Founder and Chief Executive Officer of Hyperlayer, said the results should prompt banks to think beyond the individual account model. "There's an irony to these findings, which is that banks have something fintechs don't yet have: decades of trust," Rooney said. "They're in the perfect position to serve this generation and their families. The cheapest customer a bank will ever acquire is the child of a customer it already has.

"What this research shows is that those children are not waiting around. They are already participants in the adult economy: earning, spending, saving, and worrying about money like the rest of us. But a kids' card is just the front door. Money isn't really managed by individuals but by families and households, through pocket money, shared bills, saving with a partner, and supporting a parent later in life.

"Banks have spent decades selling products to individuals, while all along the real unit of financial life has been the household. With the largest wealth transfer in history about to move through those same households, the question for banks is whether they intend to own that relationship or let it live somewhere else."

Household focus

Hyperlayer is using the findings to argue for products built around family finances rather than stand-alone accounts for single users. It said household-based services could include tools for a child's allowance, contributions from grandparents into savings, and oversight of spending for older relatives.

That approach reflects a broader shift in consumer finance, as banks face pressure from specialist apps that often target narrow use cases first and then widen their reach. For incumbent lenders and credit unions, the challenge is not only winning a child's first account but also staying relevant as financial decisions are shared across family members.

Hyperlayer positions its own product around that model and said it can be added without replacing a bank's core systems. Rooney said that point was central to the pitch to established financial institutions.

"The key for banks and credit unions is that we build all this around the regulatory approved infrastructure they already have, rather than disrupting it," Rooney said. "And none of this is theory. We run the most awarded family banking app in the highly competitive UK market, and we've been engaged to deliver multi-generation accounts by some of the world's largest banks."

The research adds to evidence that younger consumers are engaging with money earlier, often through tools and services outside the banking groups that have traditionally expected to acquire them later. In Hyperlayer's survey, the money is already there; the question is where children and their families choose to keep it.
