Executive summary: Huntington National Bank partnered with Deloitte and Google Cloud to overcome the limitations of legacy banking systems and provide corporate clients with real-time cash position visibility and automated reconciliation. Together, Huntington, Deloitte, and Google Cloud built event-based pipelines that process billions of transactions at 25,000+ events per second, with data stored in BigTable for 24/7 API access. The result: Huntington National Bank transformed from service provider to software-as-a-service partner, with productized transaction data creating new monetization opportunities across treasury, consumer, and commercial business lines.
Challenge: Traditional banks run on mainframes with batch processing cycles reconciling data overnight, but that model no longer meets modern customer demands. Legacy banking and payment systems make it difficult to unlock transaction data, with systems tightly coupled and unable to handle out-of-sequence events from independent platforms. Processing tens of millions of daily transactions required a fundamental shift from batch cycles to real-time streaming while integrating banking directly into clients' ERP workflows for faster financial book closing.
Solution: Huntington began on a year-long transformation journey with Deloitte and Google Cloud, unlocking transaction data from legacy payment platforms using Deloitte's Data Assist solution. This platform processes billions of transactions at 25,000+ events per second, handling 900+ files daily and 500+ out-of-sequence event scenarios from decoupled maintenance systems. Google Cloud technologies — including Dataflow, BigTable for high-speed caching, and Apigee for API management — enable real-time data access.
Result: Through this collaboration, Huntington National Bank now has a platform that processes millions of transactions daily, enabling near-real-time access for corporate clients to make timely decisions. By decoupling from core systems and storing data in a high-speed cache available 24/7, the bank transformed from traditional service provider to software-as-a-service partner. Transaction data is now productized for monetization, with high reusability across treasury, consumer, and commercial business lines. The AI-first thinking embedded in the platform positions Huntington National Bank for continued growth.
