Retaining Deposits and Competing With Fintechs in 2026

Traditional financial institutions are at an existential crossroads. Over $2 trillion in deposits has already shifted from incumbent banks and credit unions to fintech platforms and neobanks, according to Cornerstone Advisors, as consumers and businesses increasingly seek modern, digital-first experiences.  

While a majority (69%) of credit unions have prioritized new member growth, Cornerstone found, and bank executives have called raising deposits a top concern, digital banks are pulling ahead in the race for new checking accounts. With sleek technology and ease of use, they’re outpacing the largest traditional banks and reshaping competition for new deposits. Legacy banking infrastructure is no longer just a growth constraint; it is directly impacting account holder experience and retention.  

Over the next year, frequent users of mobile applications and online banking are significantly more likely to grow their relationship with their financial institution—through deposits, loans, or expanded services—but only if their digital experience meets rising expectations, recent research shows.* Americans who don’t currently have a savings account or checking account/debit card would be most interested in obtaining one in the next 12 months.  

Fintechs are not winning because they offer dramatically better products or lower prices. They are winning because they prioritize speed, simplicity, and convenience from the very first interaction. If outdated systems, manual processes, or channel inconsistencies slow the account opening process, banks lose relationships before they begin. And once primacy shifts, deposits follow. 

For community banks and credit unions, modern account opening can be the most direct path to stemming deposit outflows. By pairing relationship-driven service with fast, seamless, and consistent digital experiences, these institutions can compete head-to-head with digital-first players, not just to win accounts but to retain and grow deposits throughout the account holder lifecycle. 

Digital Experience Divide Driving Deposit Flight 

Consumers increasingly choose providers that are easier to use and offer integrated experiences. According to recent research, half of digital banking Americans would change financial providers for a better digital banking user experience.* They want to manage spending, saving, and borrowing without juggling multiple apps and financial institutions.  

While community banks and credit unions are paragons of relationship banking, many still contend with fragmented legacy systems. Different account types operate in separate systems that don’t communicate with each other. Opening an account often involves manual processes, in-branch visits, or restarting applications to switch channels. 

This divide can shape applicant behavior, leading potential customers to abandon new accounts and deterring existing account holders from opening more accounts. Over time, they consolidate their financial lives with providers that make expansion effortless. 

The result is a slow but compounding erosion of primacy. 

Using Modern Account Opening to Retain and Grow Deposits 

Investing in modern omnichannel account opening technology enables community banks and credit unions to deliver diverse products at the convenience applicants expect, while strengthening operational efficiency and long-term relationships with account holders. 

Modern account opening strengthens competitive position in five critical ways: 

Fast account opening for all product types for new and existing account holders 

When a prospect can open an account in minutes at a digital bank, but it takes days at a traditional institution, speed becomes a competitive disadvantage. 

Unified origination platforms accelerate the application process across retail deposits, business deposits, and lending. They enable existing account holders to open additional accounts in just a few clicks. Speed reduces friction, abandonment, and protects deposit growth. 

Unified account holder experience 

At many institutions, opening a checking or business account, or a loan involves entirely different workflows and interfaces. Adding an account feels like starting over. 

Modern platforms standardize the experience across account types. Cross-selling becomes a natural extension of the relationship rather than a friction-filled restart. When account holders can easily add accounts, they are more likely to consolidate their deposits with their existing trusted institution rather than distribute them elsewhere. 

Real-time integration 

Legacy systems often require manual handoffs between origination and core systems, delaying account access by hours or days. 

Direct core integration allows accounts to be booked and accessible immediately. Funds move seamlessly. Account holders can begin transacting right away. Real-time access reinforces confidence and prevents new accounts from becoming dormant or secondary. 

Automation that enables scale 

Manual processing creates bottlenecks that drive delays and limit growth. Staff can only process so many applications before service levels suffer. 

Automation removes these constraints, freeing bankers to focus on relationship development rather than paperwork. Institutions can grow deposits without proportional increases in back-office headcount or longer processing times. 

Accessible and actionable data 

Fragmented systems limit visibility into the full account holder journey. When origination and onboarding, digital banking, and data and marketing operate independently, institutions miss critical opportunities to deepen account holder engagement and loyalty. 

A unified platform connects data across every touchpoint, enabling proactive outreach and smarter engagement at key moments. Institutions can anticipate needs, strengthen relationships, and grow deposits sustainably. 

Stemming Deposit Outflows 

Community banks and credit unions still hold an edge: relationship banking. When that strength is combined with modern, seamless account opening infrastructure, institutions can compete on experience, retain primacy, and keep deposits in-house. 

Modern account opening empowers financial institutions to acquire new accounts while also protecting and growing existing relationships. This is critical to preventing further deposit outflows and building sustainable growth in 2026 and beyond.
