For merchants like Amazon or Walmart, the pain point is clear: traditional card payments come with 2-3% processing fees which add up fast on high volume transactions. Adopting a regulated stablecoin can help reduce those fees and speed up settlements. Merchants have two options: simply accept an existing regulated coin as payment or co-issue a coin with a trusted partner to create a branded experience. Both options allow for perks that drive usage—offering discounts, loyalty rewards or exclusive offers to encourage customers to pay with the coin vs traditional methods. Under the new law, stablecoin issuers earn interest on reserves—usually invested in T-bills—while users don't get yield directly. This can lower overall payment costs for merchants and reduce friction. The key is to ensure the reserves are fully backed and auditable so both merchants and consumers are protected. Early movers will likely be federally licensed issuers or banks or merchant-consortium coins. Public signals will be license approvals, coin announcements and integrations with major wallets or checkout systems.
