Amex Will Now Drop Your Cash Back Into Its Savings Account. It Pays 3.20%. Others Pay 4.40%.

If you carry a Blue Cash Everyday or Blue Cash Preferred card, Amex has a new place for your cash back: its own savings account. The dollar is worth the same either way. Where it sits afterward isn’t.

Since October 29, American Express lets cash-back cardholders redeem Reward Dollars straight into an Amex High Yield Savings Account at 1:1. No minimum. Deposits generally post within four business days. Automatic deposits are coming in 2027.

The press release calls the account’s yield “competitive.” As of October 28, it was 3.20% APY.

Here’s why Amex wants this

Amex didn’t hide the motive. “With the majority of our deposits coming from existing Card Members, we have a unique opportunity to bring Cards and banking closer together,” said Corey Timlin, its senior vice president of consumer banking.

Translation: cardholders are where Amex gets its deposits, and your cash back is a reason to open the account. Once it’s open and funded, the bank’s bet is that the rest of your savings follows and stays.

That’s not a scam. It’s a sales funnel.

Run the numbers

Start with the redemption. Blue Cash Preferred pays 6% at U.S. supermarkets on up to $6,000 a year, so the most you’d earn there is $360. Park $360 at 3.20% and it earns about $11.52 in a year. At 4.40%, about $15.84. The gap is $4.32.

Nobody needs to lose sleep over that.

Now the money sitting next to it. On November 1, Pibank paid 4.40% on savings, and Northpointe Bank and Western Alliance Bank (both through Raisin) paid 4.30%, per The Motley Fool’s rate table. Put a $10,000 emergency fund at Amex and it earns about $320 a year. At 4.40%, about $440. That’s $120 a year for the same cash. At $20,000, it’s $240.

To be fair, 3.20% isn’t a bad rate. The same table puts the national average at 0.38%, which pays $38 on $10,000. If your savings sits at a big branch bank today, Amex is a real upgrade.

The verdict: where your cash back lands is your call. Keeping your whole cushion at 3.20% when 4.30% is easy to find is questionable.

The move

If you like the convenience, redeem into the Amex account. It’s worth exactly what a statement credit is. Then move the balance a few times a year to wherever pays more.

If you’d rather not open another account, take the statement credit. Same dollar, one less login.

Either way, check where your emergency fund sits right now. Compare rates on our high-yield savings page and run your own balance through the savings calculator. Rates are variable, so recheck both numbers before you move anything.

File this away for 2027. When Amex switches on automatic deposits, open the redemption settings and see where your cash back is headed before the first one lands.
