A recent article in the New York Times — “Love and Money: Why Sharing Accounts Is Good for Your Relationship” — explores scholarly evidence for the benefits of couples’ combining their bank accounts. The article features the insights of Indiana University marketing professor Jenny Olson, who appeared in 2023 on the ABA Banking Journal Podcast. For a special Valentine’s Day episode, we bring back that classic podcast episode — sponsored by R&T Deposit Solutions — in which Olson discusses her research on joint accounts and couples’ well-being.

Olson and her colleagues randomly assigned new couples to one of three conditions for a two-year period: using only separate accounts, using a joint account only or to a third group that received no instructions about the kind of accounts to use. Couples in the no-instruction group and the separate account group saw declines in relationship quality during the experiment, couples with joint accounts were “buffered” against the declines otherwise expected, she says.

“Because we randomly assigned couples, we can take better steps toward understanding causality,” Olson says. “Our results really do suggest that having a joint bank account improves relationship quality.” While every couple’s financial needs are unique and separate accounts may be what’s needed in many situations, Olson discusses implications of the research for how bankers and wealth managers approach financial planning conversations with clients.
