Financial services companies, including SWIFT, are grappling with the complexities of modernizing payment infrastructures to meet the demands of real-time global transactions and strict regulatory compliance. SWIFT facilitates international payments via secure messaging but has faced challenges with its legacy systems, which were slow and produced numerous false alerts, impacting both operational efficiency and customer satisfaction. To address these issues, SWIFT adopted Elastic's platform, significantly enhancing real-time performance, reducing support response times, and improving observability by ingesting large volumes of data across numerous applications. As the industry shifts towards digital payments, regulations like PSD3 and the Instant Payments Regulation require immediate fund transfers, underscoring the need for advanced fraud detection and compliance systems. Despite these advancements, only a small fraction of banks exhibit readiness for instant payment adoption, highlighting ongoing challenges in the sector.
