Merchants can integrate stablecoin payments reliably and continue accepting fiat as usual.

Citi and Coinbase’s disclosed payment setup allows merchants that don’t want to hold coins to also accept stablecoin payments. Stablecoins are automatically converted into fiat before settlement, eliminating the merchants’ work of directly managing the coins. Whether merchants actually use this service depends on how many orders truly pay with stablecoins; whether merchants choose to keep the coins can be assessed separately.

On September 28, both parties disclosed an expanded cooperation. Under the merchants’ payment arrangement, customers pay stablecoins through Spring by Citi. Coinbase’s payment system automatically converts the stablecoins into fiat, and Citi handles settlement.

For merchants who simply want to add another payment option, this arrangement removes the need to directly manage coins. They don’t have to decide separately how to hold the coins or when to convert them for this revenue. The service provider handles the related operations, and merchants can decide independently whether to accept stablecoin payments versus holding coins long-term.

In the same announcement, Coinbase Virtual Accounts will automatically convert the received fiat into stablecoins to serve a different kind of need. The two directions of business cannot be mixed together and treated as evidence that merchants are starting to stockpile coins.

Even if, in the future, more and more payments are completed through this arrangement, you still can’t infer merchants’ stablecoin balances from payment amounts alone. Just because a merchant is willing to accept coins from customers doesn’t mean they want to keep sales revenue in coins; conversely, receiving fiat doesn’t prevent stablecoins from playing a role in that payment.

Eliminating operational steps can only explain why merchants might be willing to integrate; it still can’t prove that customers will choose it. The parties’ announcements do not disclose the actual payment volume under this cooperation, nor do they provide a complete fee schedule. Whether it’s more cost-effective than the original payment method, and whether settlement and refunds meet everyday business needs, still requires real-world usage to answer.

At present, the arrangements disclosed by both parties start in the United States, and you shouldn’t interpret it as global integration of payment options across Citi’s worldwide business scope. Only after the participating merchants continuously receive this kind of order can it be confirmed that the arrangement has been put into everyday business.
