The Hidden Cost of Digital Fragility to Long-Term Shareholder Value

Each deferral of modernisation improves one year’s result and borrows from the years that follow. The loan is real, and it sits on a ledger the accounts omit.

Technology plans carry a modernisation line, and each year it is trimmed a little. The core platform holds, the saving reaches the result and then the shareholder, and every party acts in good faith. Audit committees guard cost discipline for sound reasons, and a platform that runs is a fair thing to defer by a year.

The Reserve Bank’s Directions of July 2026 place oversight of information systems audit with the Audit Committee, which reads the estate as it stands. A trim reads as reasonable in any single year. Taken together, the trims move a cost from the budget, where it is visible, to the ageing of the systems the business runs on, where it is hidden. The saving is booked annually, and the fragility compounds annually.

The reckoning arrives on the day the oldest platform fails, and it exceeds the sum of every saving that preceded it. The emergency repair costs more than the trims ever saved, customers who waited through the long outage move their primary account, and the supervisor’s review runs on through the next two results.

A saving that the board would still count as one after the failure is a saving, and the remainder is a cost deferred at the shareholders’ risk. The Candid Conversation opens that ledger.
