World first bank migration: Move Bank on Constantinople.
By Dexter Cousins on 10/08/2026
Move Bank has become the first bank in the world to shift its entire operation, technology, product, operations and compliance, onto Constantinople's platform. Dexter Cousins sits down with Move Bank CEO Mike Currie and Constantinople co-CEOs Macgregor Duncan and Di Challenor to unpack a migration that cut cost to income by around 30 percent and what it signals for every customer owned bank in Australia.
About the guests
Mike Currie, CEO, Move Bank
Mike Currie has led Move Bank, the Brisbane based customer owned bank founded in 1968 as Railways Credit Union, since March 2023, following senior roles at QBANK, Heritage Bank and Commonwealth Bank.
