Key takeaways

The new savings option changes nothing at your terminal or on your statement. Its effect is that cardholders have more reason to keep using Amex.
On OptBlue, your processor sets your Amex price, so the markup on top of Amex's wholesale rate is the part you can negotiate.
Since April 17, 2026, most businesses can stay on OptBlue until they reach $3 million a year in Amex volume, up from $1 million. That matters most for hotels and travel sellers with large tickets.
Before you drop Amex, figure out how many sales you could lose before dropping it costs you money. In the illustrative restaurant example, that's only about 1.7% of Amex volume.

American Express now lets U.S. holders of its consumer cash back cards send their Reward Dollars straight into an American Express High Yield Savings Account. Business owners with the Graphite Business Cash Unlimited card can send theirs to an Amex Business Checking account. Nothing changes at your terminal: there's no new card, no new fee and no new routing. The Amex cash back high-yield savings option matters to sellers for a different reason. It gives Amex cardholders one more reason to keep the card at the front of the wallet, and that keeps your Amex volume, and what you pay to accept it, where it is.

What Amex Announced: Cash Back Into High-Yield Savings

The option went live October 29, 2026, according to Upgraded Points, and PaymentsJournal reported it on October 30. Amex's press release says U.S. Consumer Cash Back Card Members can redeem Reward Dollars for a deposit into an Amex High Yield Savings Account. U.S. Business Cash Back Card Members can redeem into an Amex Business Checking account.

Here's who qualifies and how it works, based on the release and PaymentsJournal's report:

Consumer cards: Blue Cash Everyday and Blue Cash Preferred holders can deposit cash back into an Amex High Yield Savings Account. They need to have that account already.
Business card: Upgraded Points notes that Amex names only one business card, the Graphite Business Cash Unlimited, for deposits into Amex Business Checking. The card launched in March 2026 and earns 2% cash back.
Terms: Rewards convert 1:1 with no minimum. For now, redemption works only through the online account; Amex says app redemption is coming. The savings rate is variable and can change at any time.

The Paypers adds context: earlier in 2026, Amex introduced American Express Business Banking, including a high-yield Business Savings Account. This move ties the cash back cards to those deposit products.

Why Card Rewards and Merchant Fees Move Together

On its own cards, Amex sits on both sides of the sale. It issues the card to your customer and runs the network that charges you to accept it. Rewards are one of the main tools it uses to win spending, and the discount fee you pay on each Amex sale helps pay for that system. We cover how this works in why rewards credit cards cost more for merchants to accept.

Amex is open about the goal. The Paypers reports that the company described rewards-to-savings as a way to build a more connected relationship with cardholders. Upgraded Points notes that the option keeps rewards money at Amex instead of letting it move to a competing bank. Once a cardholder's cash back feeds a savings balance, they have less reason to switch cards at your counter.

These are everyday-spend cards, which matters for retail. Amex's own example is Blue Cash Preferred, which pays cardholders 6% cash back at U.S. supermarkets on up to $6,000 a year, plus select U.S. streaming subscriptions. Since groceries are the headline category, supermarkets, markets and general retailers are the sellers most likely to see these cards at the register. Restaurants, hotels and travel sellers also take Amex's premium and corporate cards, which this change doesn't touch. The direction is the same, though: Amex keeps giving cardholders more reasons to stay.

Amex OptBlue Fees vs. a Direct Amex Agreement

Most small businesses take Amex through OptBlue. Under this program, your regular processor signs you up, prices Amex and puts it on the same statement as Visa and Mastercard. Amex's OptBlue page says plainly that processors set the rate for Amex acceptance, just as they do for the other card brands. That gives you your first point of leverage. The price on your statement is your processor's price, not a network rule.

Under that price is Amex's wholesale discount rate, which varies by industry and ticket size. Helcim publishes the OptBlue wholesale table. In its rentals category, for example, the rate is 1.40% + 10¢ under $150, 1.75% + 10¢ under $3,000 and 1.90% + 10¢ above that. Merchant Cost Consulting's 2026 rate summary lists separate restaurant rates for non-swipe sales (keyed or online), from 1.90% + 4¢ at Tier 0 to 2.80% + 10¢ at Tier 2. Your processor's markup sits on top of these rates, along with the network fees covered in our guide to card brand assessments and network fees.

The New $3 Million Ceiling

Effective April 17, 2026, Amex raised the U.S. OptBlue threshold from $1 million to $3 million in estimated annual Amex charge volume, measured over a rolling 12 months. The new limit doesn't apply in Puerto Rico or the U.S. Virgin Islands. Some categories have no threshold at all: charity, healthcare, education, government, insurance, residential rent, utilities and certain online gaming segments. Once you pass the threshold, you need a direct agreement with American Express, which makes Amex a separate relationship from your processor.

The change matters most for sellers with large tickets. A hotel taking room charges or a tour operator taking trip deposits could reach $1 million in Amex volume quickly. With the higher limit, many of those businesses can stay on OptBlue with one processor and one statement. If you were moved to a direct Amex agreement before April 2026, ask your processor whether you now qualify for OptBlue again and how the pricing compares.

Should Your Small Business Keep Accepting American Express?

For most sellers, dropping Amex saves less than it seems to. The math below shows why. The numbers are illustrative; use your own statement figures.

Assumptions for a full-service restaurant:

$80,000 a month in card sales, 12% of it on Amex ($9,600)
All-in Amex cost of 3.10%, against a 2.50% blended cost for Visa, Mastercard and Discover
35% contribution margin after food cost and hourly labor

Step	Calculation	Result
Extra cost of Amex vs. other cards	$9,600 × 0.60%	$57.60 a month
Yearly extra cost	$57.60 × 12	$691.20
Sales you can lose before dropping Amex costs money	$57.60 ÷ 35%	about $165 a month
Share of Amex volume that represents	$165 ÷ $9,600	about 1.7%

In this example, dropping Amex loses money if more than about one Amex guest in 60 would rather eat elsewhere than use another card. Business travelers paying with a company card may be required by company policy to use it. That's why hotels, travel businesses and restaurants near offices should check their Amex share before deciding anything.

Run the same three numbers for your business: your Amex share of card volume, the gap between your Amex rate and your blended rate on the other brands, and your margin. A tiny Amex share and a thick margin give you the most room to drop it. When Amex is a large slice of sales, the better move is usually to pay less for it. Check your processor's Amex markup, see how many of your sales land in non-swipe categories, and confirm you're in the right OptBlue industry category. MannyPay's pages on restaurant and bar payment processing and hotel payment processing cover setups for those businesses.

Surcharging and Steering Rules for Amex Transactions

Surcharging is where Amex differs most from Visa and Mastercard. Forte's surcharge tip sheet says Amex doesn't ban surcharges outright. Instead, its equal-treatment rules say you can't surcharge Amex on terms less favorable than other payment products, including debit and prepaid. Visa and Mastercard prohibit surcharging debit. IntelliPay's 2026 guide spells out the result: if you surcharge Amex, you can't follow both sets of rules exactly. Forte goes further and calls compliant Amex surcharging effectively unworkable in most cases.

Network rules are only half of it. State law decides whether you can surcharge at all and how much, and those laws vary. Amex's merchant rules also limit how you can discourage customers from using its cards. Read the relevant sections of the American Express Merchant Operating Guide before you post signs or train staff to suggest another card.

Many sellers use a cash discount or dual pricing instead. With these, the posted price applies to card payments and customers paying cash get a lower price. Network rules and state law treat these programs differently from surcharges. Our comparison of cash discount, surcharging and dual pricing explains the differences. MannyPay offers dual pricing programs, plus surcharging where it's permitted. This is general information, not legal advice. Check your setup with your processor and a qualified attorney before you change how you price.

What to Watch as Card Issuers Add Banking Features

Expect more moves like this. Amex has now linked its cash back cards to its consumer savings and business checking accounts, and app-based redemption is still to come. When issuers tie rewards to deposit accounts, their cards get harder to replace in a customer's wallet. For merchants, that means rewards-heavy cards keep their share at checkout. The fight over acceptance costs shifts to Washington and the courts, where bills like the Credit Card Competition Act are still being argued.

Here's what you can do this week. Pull 12 months of statements and write down three numbers: your Amex volume, your Amex effective rate and your blended rate on the other brands. If you're close to $3 million in Amex volume, or your Amex markup is noticeably higher than on the other brands, request a free processing quote and have a MannyPay specialist go through the statement with you. Quote requests get a response within one business day.
