DetailsAPY for each tier is based on daily balance method: 3.00% APY on balances below $5,000.00, 0.15% APY on balances equal to or greater than $5,000.00. $5.00 minimum balance fee will be imposed monthly if the average daily balance for the statement cycle falls below $100.00. The average daily balance is calculated by adding the principal in the account for each day of the period and dividing that figure by the number of days in the period. A statement cycle may be from the 17th (a calendar day) of a month to the 16th (a calendar day) of the next month. To determine your statement cycle please ask your Personal Banker at the time of account opening. Account must be open and active for 180 calendar days, or a $30.00 closing fee may be assessed at account closing. Fees may reduce earnings. See disclosure for details.

Financial Health History
WaterStone Bank’s Texas Ratio rose from 1.42% in Q3 2023 to 2.07% 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 bank’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.
