Visa and Mastercard stocks rose on Friday after The Wall Street Journal reported that Walmart and Amazon, among other retailers, are considering issuing their own stablecoins for customers, a move that could drain revenues from traditional payment service providers. The newspaper reported that decisions to issue stablecoins (cryptocurrencies tied to stable assets like the US dollar) depend on the passage of the Genius Act, which was issued by Congress, and which needs to be regulated and requires the holding of reserves in dollars or other assets.
