Households’ Interest Spending Falls Again Boosting Returns

Households have spent less on interest payments for the fifth straight quarter, even as everyday costs climb, according to a Westpac analysis of New Zealand household finances.

Interest costs keep easing despite mortgage rate shifts

Westpac’s chart pack shows that the fall in benchmark interest rates over the past year has eased the burden on borrowers. Senior economist Satish Ranchhold said the outlook for further sizable declines in borrowing costs is limited for the rest of the year. While some mortgage rates have nudged higher in recent weeks, the recent week saw a modest pull‑back on those increases.

Major banks are no longer competing aggressively on price for three‑to five‑year loans. Swap rates slipped about 15 basis points, and the decline in long‑term rates at the big lenders mirrors those wholesale movements. Current three‑year rates sit between 5.19% and 5.29%, while four‑year rates range from 5.49% to 6.49%.

The Reserve Bank of New Zealand (RBNZ) is still expected to raise the official cash rate (OCR) gradually, a move that will affect short‑term rates. However, Ranchhold noted that most mortgage borrowers—about 90%—have fixed‑rate contracts typically lasting one to two years, which should temper any sharp rise in household interest expenses in the near term.

Asset values rise while housing wealth stalls

Financial assets held by households have continued to climb, up 3.3% over the past year. Data from Cotality shows $234 billion in New Zealand Superannuation and KiwiSaver accounts, $187 billion in listed shares, and $342 billion in commercial real estate.

In contrast, the residential side tells a different story. The combined value of housing and land fell 0.5% and has essentially been flat since 2023, limiting overall wealth growth. More than $1.67 trillion is tied up in 1.73 million homes, which carry $398 billion in outstanding mortgage debt.

Residential real estate now makes up about 48% of household assets—a 5% rise since 2021—highlighting the sector’s continued significance despite the modest price movement.

Comparing this to the early‑2020s, the pattern resembles a period when low‑interest environments boosted asset portfolios but did not translate into higher home‑price appreciation. The similarity suggests that while borrowing costs can fall, broader market forces and supply limits still dictate housing value trends.

Income growth and the role of entrepreneurship

Disposable income for households has risen roughly 5% over the past year, helped in part by a 1.5% increase in the number of households. Adjusted for population changes, Westpac estimates the average household’s disposable income grew 3.8% in the year to March, up from 3.1% at the end of the previous year.

Entrepreneurial earnings have been a key driver, up 14% over the year. Strong performance in the agricultural sector, buoyed by robust commodity export prices, has contributed to higher earnings and boosted confidence in rural regions.

Even with these income gains, the impact on interest spending is muted because most borrowers are locked into fixed‑rate terms that shield them from short‑term rate hikes.

Overall, the data paints a picture of households dealing with a mixed financial environment: lower interest outlays, modest asset appreciation, and rising incomes, all set against a backdrop of ongoing inflation concerns and geopolitical tensions.
