NEW YORK--For credit unions and banks, instant payments are quickly moving from a nice-to-have feature to a competitive necessity, as younger consumers—especially Gen Z—show little patience for legacy settlement windows and increasingly reward institutions that can move money in real time.
According to PYMNTS, roughly 74% of consumers now use instant payments, underscoring how quickly expectations around access to funds have shifted.
That pressure may be especially acute for credit unions, where the member retention stakes are rising. PYMNTS reported that Gen Z consumers are more than twice as likely as the broader population to switch financial institutions, often gravitating toward fintechs that deliver the kind of seamless, always-on experiences they now view as standard. For traditional FIs, the message is increasingly clear: real-time payments are becoming table stakes, not a differentiator.
PYMNTS noted that Gen Z’s preference for instant access is shaped not just by digital habits, but by financial reality. Many younger consumers work hourly jobs or participate in the gig economy, making delays tied to traditional ACH settlement more than an inconvenience. Waiting days for funds can mean overdraft risk, late fees or difficulty covering everyday essentials such as groceries or gas. That urgency is also helping drive broader adoption of alternative payment methods, with PYMNTS pointing to Gen Z as significantly more likely than older generations to embrace digital wallets and other fast-settlement tools.
Still, many smaller financial institutions—particularly credit unions—remain on the sidelines, not because demand is unclear, but because the operational lift can be substantial. PYMNTS said 73% of financial institutions cite legacy core systems as a major barrier to modernization, while 87.8% point to high implementation costs as a key deterrent. Connecting to multiple real-time rails such as the RTP network and FedNow service can require complex integration work, 24/7 liquidity management and staffing models that many institutions historically have not built around payments.
Fraud concerns also continue to slow adoption, but PYMNTS said early movers increasingly view that risk as manageable—and often misunderstood. Institutions that have gone live with instant payments have found fraud issues are more commonly tied to account takeover and authentication weaknesses than to the speed of the rail itself. As a result, controls such as multi-factor authentication, transaction limits and velocity monitoring are emerging as the more practical answer, rather than delaying deployment altogether.
To reduce risk, PYMNTS said many successful institutions are rolling out instant payments in phases, often starting with receive-only functionality before enabling outbound transactions. That approach allows credit unions and banks to monitor member behavior, gain operational confidence and manage liquidity exposure before taking on the more complex challenges of full send-and-receive real-time capabilities.
At the same time, partnerships with service providers and corporate credit unions are helping smaller institutions shortcut the process, in some cases cutting implementation timelines from more than a year to just a few months by handling rail access and routing through a single platform.
The payoff, according to PYMNTS, extends well beyond faster payments. Institutions that successfully deploy instant rails are finding new opportunities in areas such as earned wage access, immediate loan funding and digital wallet transfers—services that can deepen relationships with younger members and help credit unions compete more effectively with digital-first challengers.
