Financial Health History

SIOUX VALLEY COOP’s Texas Ratio rose from 5.36% in Q2 2023 to 7.27% in Q1 2026, so its financial health has held steady at a healthy level over the past 12 quarters. Over the same period its Star Rating moved from 5.0 to 5.0 and its Health Grade from A+ to A. Lower Texas Ratios are healthier; the green zone below the amber 15% line is where a credit union must stay to qualify for the MBR Verified Healthy badge. Hover over or tap a point for that quarter’s figures.

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.
