New Zealand’s biggest banks have lifted their floating mortgage rates by the full quarter of a percentage point within days of the Reserve Bank raising the Official Cash Rate, and the speed of the move has reopened an old argument about whether floating borrowers get a fair deal.
The Reserve Bank lifted the OCR by 25 basis points to 2.50 percent on 8 July, the first increase since 2023 after a long run of cuts. In its statement, the Monetary Policy Committee said that “with inflation still above target and economic activity expected to strengthen, some further reduction in monetary stimulus is likely to be required to return inflation to the 2 percent target mid-point”. Annual inflation was running at 3.1 percent in the March quarter and the bank now expects it to peak at 3.9 percent in June before easing back towards 2 percent by the middle of 2027.
The committee also warned that this may not be the last move. “Further OCR increases appear likely at upcoming meetings,” it said, while adding that “their timing is highly uncertain”. The six members reached consensus on the increase, though they were split on where the bigger risks sit. External members Prasanna Gai and Hayley Gourley saw the risks tilted to the upside, while Governor Anna Breman, Karen Silk, Paul Conway and Carl Hansen judged them to be broadly balanced.
Westpac was first to move on its floating home loan rates, and Kiwibank, ASB and BNZ followed quickly. Westpac lifted its variable home and business loan rates by 0.25 percent, taking its Choices Floating and Choices Offset products to 6.14 percent and Choices Everyday to 6.24 percent. ASB’s housing variable rate rose to 6.04 percent and its Orbit variable rate to 6.14 percent. BNZ’s standard variable rate climbed to 6.09 percent, with three other variable rates moving to 6.19 percent. In each case the higher rates take effect over the following week or two for both new and existing customers.
Notably, the banks left their fixed home loan rates alone. BNZ, ASB and Westpac all held their fixed rates steady, so the immediate pain from the OCR rise falls on the smaller group of borrowers sitting on floating rates rather than the majority who fix.
What has drawn attention is the contrast between how banks handled the cuts and how they handled this rise. Over the past two and a half years the OCR fell by 275 basis points, from 5.25 percent in early 2023 down to 2.5 percent by late 2025. During that long slide, the main banks did not pass all of it through to floating borrowers. An analysis by interest.co.nz that tracked floating rate changes found ANZ, ASB and BNZ held back about 40 basis points, while Kiwibank and Westpac held back around 50 basis points. Yet when the OCR went up by 25 basis points this month, every bank passed it on in full. As the site put it, “all the main banks have held back some of the OCR change on the way down. But for the July 9 increase, they passed it all on.”
That asymmetry matters because floating rates are one of the few places where borrowers can see a bank’s pricing decisions in plain sight. Fixed rates are shaped by wholesale swap markets and shift constantly, so it is harder to point to a single decision. Floating rates move when a bank chooses to move them, which makes the gap between the cuts held back and the rise passed on easy to measure and hard to explain away.
For households on a floating rate, the practical question is what to do now. The interest.co.nz analysis suggested borrowers could either shop around, including at smaller lenders such as the Co-operative Bank, or shift onto a short fixed term, since six-month and one-year fixed rates currently sit below the floating rates on offer. Floating rates buy flexibility, but that flexibility is now costing a clear premium.
The wider direction of travel is less certain. Economists at ASB, quoted by RNZ, described the move as the start of a modest tightening cycle and expect shorter-term fixed rates to keep drifting up. They noted that “fixed-term mortgages have been moving significantly between each OCR announcement and will continue to do so”, with two-year rates already climbing from about 4.5 percent to around 5.2 percent. Their broader message to borrowers was that even if the economy stumbles and rates ease again, mortgage rates are likely to settle “in a much higher range than the historic lows struck during Covid-19”.
There is a political edge to all of this as well. The rise lands in an election year, when the cost of servicing a mortgage is one of the most direct ways voters feel the state of the economy. A tightening cycle that pushes repayments up, however modestly, is not the backdrop any government would choose going into a campaign, even though the Reserve Bank sets the OCR independently.
For now the message from both the central bank and the commercial banks is consistent. The era of falling rates has paused, borrowing is getting a little more expensive again, and anyone on a floating rate is feeling it first.
