BMW Bank pays more over a full year: 4.15% APY against Western Alliance’s 4.30% for the first 90 days, then 4.00% (both on Raisin, checked Nov 8, 2026). Western Alliance is ahead for the first 90 days, BMW catches up around day 180, and on $25,000 BMW ends year one about $19 ahead. The gap is small. Both have $1 to open, no fees, FDIC insurance at separate banks, and both count toward Raisin’s STACK bonus for new customers through Nov 30, 2026.

Do both accounts count toward the STACK bonus?
Yes. Raisin’s STACK welcome bonus is based on your total qualifying deposit with partner banks on the Raisin platform, so money split between BMW Bank and Western Alliance adds up toward one tier:
| Total deposited within 14 days | Welcome bonus |
|---|---|
| $10,000 to $24,999 | $40 |
| $25,000 to $49,999 | $100 |
| $50,000 to $99,999 | $200 |
| $100,000 to $199,999 | $425 |
| $200,000 or more | $900 |
You must be new to Raisin, enter code STACK at sign up, start your first deposit by Nov 30, 2026, 11:59pm ET, deposit within 14 days and keep the money on Raisin for 90 days. If your balance drops below a tier during those 90 days, you get the lower tier. The extra Savings + CD Boost ($10 to $100) needs at least $1,000 in a CD as well; a second savings account does not count. Full details in our Raisin STACK bonus guide.
Should you split money between BMW and Western Alliance?
Splitting makes sense in two cases:
- You have more than $250,000. BMW Bank and Western Alliance Bank are separate banks, so each has its own FDIC limit of $250,000 per depositor, per ownership category. Through one Raisin login, a single owner could keep up to $500,000 insured across the two. See how to insure more than $250,000.
- You want both the 90 day lock and BMW’s higher ongoing rate. In practice the difference is a few dollars, so most people are better served by keeping it simple.
One catch: if you also have Western Alliance’s direct Premier account, balances in both Western Alliance accounts count toward one FDIC limit. See Raisin vs Premier.
Are BMW Bank and Western Alliance safe?
Yes. BMW Bank of North America (FDIC certificate 35141) is owned by BMW Financial Services NA. Western Alliance Bank (FDIC certificate 57512) is the same bank behind Western Alliance’s direct Premier account. On Raisin, your money is held in a custodial account at the bank you choose and is eligible for pass through FDIC insurance if the conditions are met.

Our take
For most people opening a Raisin savings account, BMW Bank is the better long term pick at today’s rates, by a small margin. Western Alliance wins only for money you will move within about six months. Either way, the STACK bonus is worth far more than the rate gap if you can deposit $10,000 or more by Nov 30. Compare both with every other account in our best high yield savings accounts.
