US Yields Drive Up New Zealand Mortgage Rates

Rising US government bond yields are driving up New Zealand’s wholesale interest rates, putting pressure on fixed mortgage pricing. Kiwibank economists noted that US rates are at their highest in 25 years, with strong economic data prompting traders to anticipate further Federal Reserve tightening. This has trickled down to local swap rates, which lenders rely on to set fixed-term home loan rates.

The gap between New Zealand’s two-year and 10-year government bond rates has widened to 120 basis points, up from 100 in May. Kiwibank described this as a result of global rates 'lifting and twisting' the local yield curve. While swap rates eased slightly last week, with the two-year rate dropping to 4.02% and the five-year rate to 4.41%, fixed mortgage rates for two- to five-year terms remain above 5%.

Market expectations for the Reserve Bank of New Zealand’s official cash rate (OCR) are diverging from the central bank’s own projections. Overnight index swap pricing suggests an OCR of about 3.1% by the end of 2026, with markets forecasting further hikes above 4% in 2027. Kiwibank economists believe markets have overpriced future rate increases, while other banks like Westpac, ANZ, and ASB have differing views on the OCR’s peak.

The weakening New Zealand dollar, now below 56 US cents, is offering mixed benefits. It supports exporters and tourism but adds to inflation pressures from fuel and imports. Domestically, filled jobs rose in September, but consumer confidence remains stagnant, with Kiwibank highlighting a recovery in sentiment as crucial for economic recovery.
