The ISO 20022 standard has officially taken effect as of November 22, 2025, mandating all financial institutions to adopt it for payment instructions. This transition marks the end of the old SWIFT message system, significantly impacting cross-border payments and large financial transfers. Six cryptocurrencies—XRP, XLM, HBAR, ALGO, IOTA, and XDC—have been identified as key utility chains due to their compatibility with the new ISO 20022 messaging standard. SWIFT has cautioned users about potential service disruptions and advised against sending messages during a designated maintenance window to ensure a smooth transition.
