Amazon and Walmart are exploring stablecoins to cut rising card payment costs and streamline transactions. Backed by fiat or commodities, stablecoins offer faster settlement, reduced fees and fewer intermediaries. With US interchange fees hitting $187.2 billion in 2023, even partial stablecoin adoption could save major retailers billions. Global corporations including Apple, Airbnb, Shopify and Revolut are also entering the stablecoin space. As we see more regulatory clarity around issuance and reserves, adoption may accelerate. Stablecoins are no longer niche tools but emerging payment infrastructure with the potential to challenge traditional banks and card networks.
