With SWIFT’s ISO 20022 compliance deadline looming in November, several banks are behind schedule.

Cross-border payments are approaching a hard deadline in November, when SWIFT stops accepting unstructured address data under ISO 20022. The global messaging standard that replaced the old SWIFT MT format, ISO 20022 was designed to give every country’s banks a common baseline, and November’s structured-address requirement is the next phase of that migration.
SWIFT data from April showed that 61.2% of payments still carried unstructured debtor addresses, and 62.9% unstructured creditor data. This matters; once fully unstructured addresses are removed, noncompliant payments risk rejection or delay, with no fallback transition layer for missing address data.
A March survey of senior payments professionals across Europe and North America by RedCompass Labs found that 44% of banks were behind schedule on readiness for SWIFT’s removal of unstructured addresses. Pratiksha Pathak, RedCompass senior vice president and head of payments, attributed that figure to years of treating the wider ISO 20022 migration as a message-format exercise rather than the data quality overhaul it was always meant to be.
Scale and Legacy Hurdles
Anxiety about readiness was clear but uneven, with 20% of the very largest banks deeming the deadline “unrealistic,” compared with 5% of smaller banks, indicating that scale and legacy systems are part of the problem. This was not for lack of trying; most banks are spending around $20 million on the requirements, with larger institutions spending over $30 million.
Bank readiness has shifted since March, Pathak noted. Some trailblazers have rolled out “brilliant” programs, she said, while laggards still hope SWIFT will push back the clock. That won’t happen, Pathak said: “They’re not moving the deadline.”
Lloyds is among the banks that recognized the central issue early, building its solutions around structured data from the outset. API-based channels natively support the required fields, backed by validation controls and proactive client outreach, including a ramp-up in dedicated resources as November approaches.
“The biggest challenge isn’t usually the payment message itself,” said Surath Sengupta, head of transaction banking products at Lloyds. “It’s the readiness of the underlying data. Many organizations already hold most of the required information, but it’s often stored inconsistently across ERP and treasury systems.”
Early movers aren’t aiming just to meet the deadline, he said. They are positioning themselves to capture the broader gains from automation that follow, “from increasing automation and reducing friction to laying the foundations for the next generation of cross-border payments.”
Industry estimates suggest that 5% to 10% of payments currently generate sanctions screening alerts requiring manual review, a friction that richer structured data should directly ease.
‘Beyond’ ISO 20022 Compliance
Not every treasurer is equally confident in the guidance they receive, however. Some have faced practical challenges with the availability of detailed technical specifications and implementation guidance from banking partners, said Marianna Polykrati, group treasurer at aquaculture producer Avramar: “Many corporates are still waiting for this information.”
Ownership of payment process and master data varies across organizations. At Avramar, treasury and accounts payable share the responsibility, making close collaboration essential.
“Our preparation goes well beyond generating ISO 20022 XML files,” said Polykrati. “We see this as a data quality and process transformation project. As we prepare for an ERP migration by the end of the year, we are using this opportunity to clean up master data, standardize payment workflows, and strengthen governance. Rather than treating ISO 20022 and the ERP implementation as separate initiatives, we see them as complementary projects.”
While compliance may be the starting point, “operational improvement is where the real value is created,” she said, echoing Pathak and Sengupta’s views. With just two months to go, the real test may not be whether the deadline holds, but how many organizations have treated it as an opportunity for long-term gains rather than a burdensome medium-term obligation.
