NAB Flags $961m Charge Over Iran War

NAB announced a A$1.35bn ($961m) pre‑tax amortization charge in H1 FY2026 due to software asset write‑downs.
Credit impairment provisions rose to A$706m ($504m) in H1 2026, up from A$485m in H2 2025, reflecting economic weakness and fuel risks.
NAB shares fell nearly 4% to A$40.73, dragging the ASX 200 down 0.4%, while peers moved less than 1%.
CET1 ratio dropped 20 basis points to just over 12% after higher interest‑rate volatility, NZD weakness and new provisions.
