A technology foundation tailored made for global growth
Legacy banking systems around the world often involve manual workflows that constrain a bank’s ability to scale across borders. Customer onboarding can be time-consuming, while payment processing, compliance reviews, and operational workflows may require multiple touchpoints across disconnected systems. These challenges can impact efficiency, customer experience, and an institution’s ability to respond quickly to changing market demands.
Hamilton Reserve Bank selected Temenos as a strategic technology partner to help deliver a modern, integrated, and modular banking platform capable of supporting its growing international client base. Backed by a significant technology investment and a clear growth strategy, Hamilton Reserve Bank deployed Temenos Core, Temenos Digital, Temenos Payments, and Temenos Financial Crime Mitigation in just nine months. In 2026, the bank further modernized its technology environment through Temenos Leap methodology and an upgrade to the 2025 version of Temenos. It also further enhanced its digital capabilities throughout, delivering fully automated banking systems. All the above was completed in a record-breaking 7-month period.
These initiatives established a unified digital foundation for Hamilton Reserve Bank, connecting onboarding, payments, compliance, and operations, and replacing fragmented workflows with end-to-end automation designed to support continued international expansion and real-time cross-border payments.
Investment in banking technology and innovation is essential for delivering sustainable growth and operational excellence. With a US$100 million IT budget, Hamilton Reserve Bank proves successful banking equals success in technology innovation.”

Delivering a seamless digital banking experience fast
A key priority of Hamilton Reserve Bank’s transformation was modernizing customer onboarding with speed and accuracy. Previously, manual processes resulted in approval time of up to five days. Through Temenos, Hamilton Reserve Bank introduced a fully automated digital onboarding experience supported by Straight-Through Processing, automated compliance checks, and real-time identity verification. Individuals can now open accounts in as short as 20 minutes, while business accounts are typically completed within 1 day.
Advanced facial recognition technology enables identity validation against official documentation such as a passport, helping improve convenience while supporting compliance and fraud prevention.
We wanted to create a digitalized and fully compliant customer onboarding experience that allows clients to open accounts in minutes without compromising fraud detection. Temenos has delivered these critical capabilities for Hamilton Reserve Bank.”

Launching fast, secure global banking at scale
Hamilton Reserve Bank required a platform capable of supporting cross-border banking services with consistency and reliability as it expanded internationally.
The bank now processes transactions in 126 currencies through an expanding network of correspondent banks, enabling same-day global payments and improved transaction processing visibility. Clients benefit from 24/7 access to commercial, private, custodial, and investment banking services.
The Temenos technology platform also enables a unified approach to banking for cryptocurrencies and traditional fiat assets, allowing clients to manage both within a single banking environment through secure crypto on-ramp and off-ramp executions delivered in 1 hour without limit in amount or frequency.
Temenos allows us to process multicurrency transactions as well as cryptocurrency conversions in real time while maintaining full compliance with global regulatory requirements.”

Strengthening pristine compliance and operational efficiency
As the bank expands globally, maintaining consistent compliance across jurisdictions becomes a critical priority.
Temenos Financial Crime Mitigation introduced real-time transaction monitoring, automated screening, and integrated compliance workflows across onboarding and transactions. This strengthened oversight while eliminating manual intervention and helping the bank maintain consistent controls as it expanded globally.
Automated e-KYC, AML, and OFAC screening processes have reinforced the bank’s regulatory framework while improving operational efficiency. Integrated workflows enable teams to focus more time on customer service and value-added activities.
We have not experienced a single incident of loss due to false or mistaken client identity since initially adopting Temenos many years ago. Every banking transaction is processed within a secure, identity-verified environment consistent with full BSA/AML compliance.”
Sebastian Ambrose, Chief Legal Officer and AML Counsel, Hamilton Reserve Bank
