# 2026 Banking and Insurance Stress Tests — Scenarios (Reserve Bank of New Zealand / APRA Trans-Tasman Joint Exercise)

The Reserve Bank of New Zealand and Australia's APRA have published the scenarios for their joint 2026 Trans-Tasman stress test of the four largest banks, alongside a pioneering reverse stress test for the life and health insurance sector that requires participants to work backwards from a pre-defined failure outcome to identify plausible triggering scenarios. This APAC-region exercise is a live model of the pre-mortem and reverse stress-testing logic that mid-market boards should be applying to their own strategic decisions — surfacing institution-specific blind spots rather than relying on generic adverse scenarios. SEA board members can use the RBNZ's published methodology as a template for running their own board-level decision rehearsals on geopolitical, credit, and liquidity tail risks.
