Financial Health HistoryFrost Bank’s Texas Ratio stayed near 2.87% in Q3 2023 to 2.74% 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 4.0 to 5.0 and its Health Grade from B+ to A+. Lower Texas Ratios are healthier — this bank’s entire history sits far below the 15% threshold 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. Show the quarterly figures
