American Express

 

American Express (Amex) is one of the four major global card networks, operating as both the card scheme and, in most cases, the issuer. With over 130 million cards in circulation across more than 130 countries, it is a globally recognised payment brand with a distinctly premium cardholder profile. Amex cardholders tend to have higher average spend and a strong concentration in business travel, corporate purchasing, and premium consumer segments.

For merchants in travel, hospitality, luxury retail, and B2B-oriented sectors, Amex acceptance is often commercially justified. The higher average transaction value and cardholder loyalty can offset the higher cost of acceptance. For merchants in lower-margin or high-volume, low-ticket categories, the cost-benefit calculation looks different.

On the fee side, Amex operates differently from Visa and Mastercard. In Europe, Amex is not subject to the interchange caps introduced under the EU Interchange Fee Regulation, which cap consumer card interchange at 0.2% for debit and 0.3% for credit. Amex sets its own merchant discount rates, which are typically higher, often in the range of 1.5 to 3% depending on merchant category, volume, and contract type. For merchants processing significant Amex volume, this is a meaningful cost line.

Acceptance is handled either through a PSP that participates in the OptBlue programme, where Amex acceptance is bundled alongside Visa and Mastercard processing, or through a direct merchant agreement with Amex. OptBlue is the more common route for most merchants and allows for negotiation at the processor level. For high-volume merchants processing over $1 million annually in Amex transactions, a direct agreement with Amex is required, and rates under that model are less standardised and worth scrutinising carefully.

If Amex is already in your payment mix, the rate you are paying is worth reviewing. It is one of the more negotiable cost lines in a merchant’s payment setup, particularly for merchants with strong Amex volume or a premium customer profile.
