The Rise of Online Banks
Online-only banks (sometimes called neobanks or digital banks) have grown dramatically since 2010. Institutions like Ally, Marcus, SoFi, Discover Bank, and dozens of others offer high-yield savings accounts, checking accounts, and loans entirely through apps and websites — with no physical branches. Their low overhead allows them to offer rates and fee structures that rival credit unions.
Savings Rates: Who Wins?
Online banks and credit unions are the two strongest competitors for deposit rates:
- Online banks: Consistently offer top-tier high-yield savings account rates, often matching or exceeding the best credit union rates. No membership requirements.
- Credit unions: The best credit union rewards checking accounts can pay 3–6% APY on balances up to $25,000 — a rate most online banks cannot match on liquid checking. Credit union CD rates are also highly competitive.
Loan Rates
Credit unions generally offer lower auto loan and personal loan rates than online banks, particularly for members with excellent credit. Mortgage rates are comparable across both categories — shopping and comparing remains essential.
Technology and User Experience
Online banks have invested heavily in their apps and UX, and many set the benchmark for digital banking experiences. Large credit unions offer comparable mobile apps, but smaller credit unions may lag on cutting-edge features. The gap is narrowing as credit unions adopt modern core banking platforms.
Physical Access
Online banks have zero branches by definition. Credit unions typically have at least one branch, and many participate in the CO-OP Shared Branch network (5,600+ locations) and surcharge-free ATM networks (30,000+ machines through CO-OP and Allpoint). If you ever need to deposit cash, an online bank is a significant inconvenience; a credit union is usually a better fit.
Customer Service
Credit unions consistently score higher on member satisfaction surveys than both traditional banks and online banks. Credit union staff are typically empowered to make exceptions and work with members individually. Online bank support is usually app or chat-based with varying quality.
The Verdict
For pure savings rate maximization on a simple high-yield savings account, the best online banks are hard to beat. For a complete banking relationship — checking, savings, auto loans, mortgages, and personal service — credit unions offer exceptional value. Many savvy consumers use both: an online bank for high-yield savings and a credit union for loans and primary banking.
Frequently Asked Questions
Reputable online banks are FDIC-insured, providing the same $250,000 deposit protection as credit unions' NCUA insurance. Both are equally safe for insured balances.

Yes. Most online banks participate in surcharge-free ATM networks (Allpoint, MoneyPass) and often reimburse out-of-network ATM fees. However, they generally cannot process cash deposits, which is a significant limitation.
Absolutely, and many people do. A common strategy: use a credit union for loans and primary checking, and an online bank (or credit union high-yield savings account) for maximizing savings rates.
