Credit crunch: Visa tumbles on Amazon ban in UK

Losses accelerated in the afternoon after a Bloomberg News report that Amazon.com is also considering changing its co-branded credit card to rival Mastercard.

Visa Inc. posted its biggest decline in over a year and a half on Wednesday, dragging down industry peers such as Mastercard Inc., after Amazon.com Inc. said it will stop accepting purchases made with the company’s credit cards issued in the U.K. as of next year.

Shares of Visa slumped 6.5%, erasing about $33 billion in value, as Amazon kicked back against the high fees charged to process transactions. Losses accelerated in the afternoon after a Bloomberg News report that Amazon is also considering changing its co-branded credit card to rival Mastercard.

The slump adds to what has been a painful three-and-a-half months for Visa, extending its drop from a July record high to 20%. Among other card companies, Mastercard pared some of its earlier drop to lose 3.5%, American Express Co. slipped 0.8% and Synchrony Financial fell 1.9%.

“While we think this is a negative for Visa if Amazon follows through with its plans, we also believe that the two companies will likely reach an agreement that lowers Amazon’s U.K. credit card fees on the Visa network,” said Piper Sandler analyst Chris Donat.

The upcoming U.K. ban is the latest in a series of changes that Amazon has made regarding Visa’s credit cards internationally this year. In August, the e-commerce giant told customers in Singapore that it would be imposing a 0.5% surcharge on all orders made with a Visa credit card. Less than a month later it announced a similar move for customers in Australia.

Investor sentiment toward Visa and other credit card stocks has also waned in recent months amid a surge in so-called “buy now, pay later” offerings. Companies such as Affirm Holdings Inc., Afterpay Ltd., and Klarna Inc. have seen a surge in popularity this year, fueling concern that consumers will become less reliant on credit cards. Still, analysts have downplayed the risks, saying fears of a structural change are overblown.
