Financial Health History
SIU Credit Union’s Texas Ratio rose from 3.31% in Q3 2023 to 4.91% in Q2 2026, so its financial health has stayed very strong over the past 12 quarters. Over the same period its Star Rating moved from 5.0 to 5.0. Lower Texas Ratios are healthier — this credit union’s entire history sits far below the 15% threshold for the MBR Verified Healthy badge.

How to read this chart: the two lines move in opposite directions by design. The Texas Ratio (blue) measures trouble, so a rising blue line means more non-performing assets against capital. The Star Rating (green) and Health Grade chips measure strength, so they fall when the Texas Ratio climbs and recover when it drops.
