What each bank pays on deposits
An advertised rate tells you what a new savings account earns today. It cannot tell you how the bank has priced the savings and money market deposits it already holds, over time. This section shows that. The figure is computed from the interest expense and deposit balances that every bank files with the FDIC in the same form. That is what makes it comparable across banks and across quarters.
Ally Bank
The two figures answer different questions, so they sit side by side and are not combined.
In Q2 2026, Ally Bank paid a higher average rate on savings and money market deposits than 94% of banks that reported a figure (FDIC call report). The all-bank median was 1.45%.
Each figure is that bank's own charter-level average across its whole deposit book, so the two are shown one after the other and are not a ranking.
Capital One
The two figures answer different questions, so they sit side by side and are not combined.
In Q2 2026, Capital One paid a higher average rate on savings and money market deposits than 92% of banks that reported a figure (FDIC call report). The all-bank median was 1.45%.
Average annualized rates paid on savings and money market deposits, and on all interest-bearing deposits, quarterly. The FDIC line for savings includes money market deposit accounts and business savings deposits and does not separate consumer accounts. Source: FDIC call report data, as reported; it may be amended. The percentile compares all FDIC filers, count-weighted. A missing quarter is suppressed, never interpolated. The percentile counts the banks that paid strictly less on savings and money market deposits, one vote per bank, among the banks that reported a figure for the quarter.
CD rates, term by term
Ally Bank lists CDs on Banksparency at 3, 6, 9, 11, 12, 18, 36 and 60 months. Capital One lists CDs at 6, 9, 11, 12, 18, 24, 30, 36, 48 and 60 months. Each row below is one term, with the best rate each bank advertises for it.
