Australian and New Zealand banks would remain resilient and continue lending for a deep recession driven by geopolitical tension and an oil price spike, according to regulators in their first joint stress test since 2017

Cross-border stress tests of this kind are rare and tend to be read less for the pass verdict, which is usually designed in advance, than for the severity assumptions regulators choose to publish. The scenario here, a deep recession combined with geopolitical tension and an oil shock, is an unusually stagflationary framing for the Australasian banks, since the relevant transmission is not the usual one of falling rates compressing net interest margins but of rising input costs squeezing borrowers while inflation limits the central banks' room to ease. A joint exercise across APRA and RBNZ jurisdictions is itself notable given how infrequently the two have coordinated publicly, and the 'continue lending' language is the standard formulation regulators use to counter procyclical deleveraging rather than a statement about capital actions. Results of this sort historically have limited market read-through on the day, with the tell being whether either regulator follows up with capital buffer guidance, dividend expectations, or revisions to minimum requirements. Given how dated the prior joint exercise is, the methodological assumptions are the detail worth scrutiny rather than the headline resilience claim. The bank equities in question tend to trade on housing and margin data regardless, so the stress test functions as a floor on perceived tail risk rather than a driver.
