Westpac has increased its floating interest rates by 25 basis points, directly reflecting the Reserve Bank of New Zealand's latest monetary policy adjustment.
The lender's decision comes immediately after the central bank raised the Official Cash Rate (OCR) from 2.25% to 2.5% on Wednesday.
The rate hike was not a surprise to financial markets, which had largely priced in the move ahead of the announcement.
By passing on the full 25 basis points to floating-rate customers, Westpac aligns its lending costs with the new policy stance, ensuring margins remain consistent with the higher cost of funds.
This adjustment impacts borrowers on variable-rate mortgages and business loans, who will see an immediate increase in their interest expenses.
For investors, the move signals that major banks are responsive to monetary tightening, even when the policy shift is anticipated.
