ASB hikes home loan rates amid volatility in wholesale interest rates
ASB said volatility in wholesale interest rates over the past month is driving changes to its lending and deposit pricing. It raised two-year term deposit rates by 20 bps to 4.20%, and nine- and 18-month rates by 15 bps to 3.70% and 4.15%. ANZ also lifted fixed home loan and term deposit rates by 10 to 26 bps.
How this was made

The 30-second read
Why it matters
By raising term deposit rates across maturities, ASB is likely responding to higher wholesale funding costs, which can influence net interest margin and competitive positioning for retail deposits.
Market read
Traders can use the disclosed bps changes as a near-term read-through on NZ bank funding-cost pass-through and rate sensitivity.
What to watch
The article does not cover loan rate changes, deposit mix shifts, or hedging costs, which are key to determining whether NIM improves or deteriorates.
Background
The piece attributes ASB’s deposit rate increases to volatility and a rise in wholesale interest rates over the past month.
Ticker impact
ASB raised its 2-year term deposit rate by 20 bps to 4.20% and lifted other maturities amid wholesale rate volatility.
Near-term sentiment likely neutral to slightly negative for earnings expectations if funding costs rise faster than loan repricing.
The article discloses specific deposit rate changes tied to wholesale rate volatility, but provides no loan demand, credit, or margin guidance to quantify earnings impact.
Market effects
Signals NZ bank funding-cost pass-through risk, potentially influencing how traders price NIM sensitivity across peers.
NZ retail banking rates may reprice quickly as wholesale rates move, affecting local fixed-income and mortgage expectations.
Wholesale rate volatility is framed as global, so similar funding-cost dynamics could matter for other rate-sensitive lenders.
Counterpoint
Deposit rate hikes could attract more stable funding and offset margin pressure if loan repricing lags less than feared.
