NZ wholesale curve
The wholesale swap curve is the base rate almost every corporate loan and bond in New Zealand is priced over — a margin is added on top. Business Borrowing tracks the whole curve daily, from the OCR and BKBM bank-bill fixings at the short end to the 15-year swap.
As at 2026-10-29, the indicative New Zealand wholesale swap curve runs from the 2.75% Official Cash Rate and 3.16% 90-day BKBM at the short end to 4.09% at 3 years, 4.25% at 5 years, 4.57% at 10 years. It is the base rate NZ corporate loans and bonds are priced over, before any credit margin.

The wholesale swap curve is one full set of NZ interest-rate benchmarks for each trading day: the Official Cash Rate, BKBM bank-bill fixings at 1–3 months, and swap rates from one year out to fifteen.
A corporate borrowing rate is the swap rate at your tenor plus a credit margin. When the curve moves, the base cost of debt moves with it — before any change in the borrower's own credit. Watching the curve tells you how much of a rate change is the market and how much is you.
