    Zions and Western Alliance Q3 prints highlight deposit costs and NIM pressure

    Question

    Zions and Western Alliance Q3 prints highlight deposit costs and NIM pressure

    Direct answer

    Regional banking institutions Zions Bancorporation and Western Alliance disclosed Q3 2026 earnings that demonstrated earnings durability alongside persistent deposit cost headwinds. Zions generated $893 million in revenue and $1.78 in EPS, exceeding consensus forecasts by 8.54%, but its net interest margin declined to 3.2%. Western Alliance delivered top-line expansion with revenue of $1.02 billion, an 8.1% year-over-year gain, and EPS of $2.45. However, operational efficiency metrics deteriorated, with Western Alliance posting an efficiency ratio of 58.1% against an anticipated 56.5%. The prints indicate that while balance sheet volume and commercial credit performance remain stable, asset-liability repricing dynamics continue to cap net interest margin expansion across mid-sized regional lenders.
