APYs are variable and can change at any time. The FDIC national average is a floor for what an ordinary savings account pays, not a competitor. Named comparisons use each product's last issuer-page check.

What is Vio Bank Cornerstone Money Market?

Editorial review
Vio Bank's Cornerstone Money Market has a strong parent in MidFirst Bank and a history of competitive rates, but its public rate data is a mess. The honest verdict: a fine rate with a fee trap for paper statements and stale marketing numbers everywhere; verify before opening. The account pays 3.55% APY per Yahoo Finance as of early July 2026, though confidence in that figure is low: older sources still circulate wildly stale numbers, including a 5.30% claim that is years old. Opening requires $100, there is no minimum balance for the rate, and the $5 monthly fee is waived with e-statements. FDIC insurance runs through the MidFirst Bank charter to $250,000. The catches: the paper-statement fee trap, no ATM access and ACH-only transfers, a dated app, and messy public rate data that demands a check at viobank.com first.
