The Bank of New York Mellon Implements ACI Global Payments Hub

The ACI Global Payments Hub provides a consolidated, enterprise payments solution for internal and external financial message switching.  The solution is a gateway to various financial networks such as SWIFT, telex, and a number of real time gross settlement (RTGS) systems.  By replacing several messaging gateways with a single message hub, the bank will achieve greater efficiencies and consistency across all operations and products. 

The Bank of New York Mellon is an acknowledged global leader in providing securities services that enable some of the world’s largest and most sophisticated institutions to move and manage their financial assets in more than 100 markets worldwide.  The ACI payments hub supports these critical missions by offering the bank a solution that combines comprehensive functionality with financial messaging, payment processing and liquidity management capabilities.  

"We welcome The Bank of New York Mellon to our list of leading financial institutions leveraging the comprehensive functionality of ACI’s world-class payments software," said Ralph Dangelmaier, president of the ACI Worldwide Americas.  This is one of many implementations of the ACI payments hub worldwide, and is further testament to our 30 years of proven experience and expertise in developing and delivering business-critical banking systems."
