What Survives a Migration?

Periodic Payments and Inertia at a Member-Owned Lender

A paper from the School of Emergent Priorities uses a core-banking migration at an unnamed member-owned lender, in which 6,214 periodic payments held in a superseded record format were cancelled with notice while 22,870 others were carried across untouched, to estimate how much of a stock of standing instructions persists through inertia. Within 78 weeks 55.7 per cent of the cancelled instructions had been set up again; re-establishment depended on what the payment was for and how old the instruction was, and not detectably on its amount.
