New Zealand borrowers may not have seen the last of rising interest rates.
In its latest economic outlook, Kiwibank's economists have warned that the Reserve Bank is now signalling a much more aggressive stance toward inflation than previously expected, with the possibility of Official Cash Rate (OCR) increases beginning as early as July.

The warning comes as households continue to grapple with elevated living costs, stubborn inflation pressures and ongoing uncertainty surrounding global energy markets.
Reserve Bank Changes Direction
While the Reserve Bank left the OCR unchanged at 2.25% at its latest meeting, Kiwibank says the decision was far from reassuring.
The Monetary Policy Committee was split evenly, with external members reportedly favouring an immediate rate hike while internal members voted to hold. Governor Christian Hawkesby's casting vote ultimately kept rates unchanged.
According to Kiwibank, financial markets are now pricing a very high probability of an OCR increase at the next review.
The bank believes the Reserve Bank has become increasingly concerned about future inflation pressures, despite signs that economic activity remains weak.
Households Already Feeling The Squeeze
Kiwibank's economists argue the economy remains fragile following the double-dip recession experienced during 2024 and 2025.
The report suggests many businesses and households have yet to fully recover before being confronted with fresh pressures arising from higher fuel costs, geopolitical instability and renewed inflation concerns.
The economists question whether higher interest rates are the appropriate response.
Their view is that rising oil prices and energy-related inflation cannot be solved through monetary policy.
Instead, they argue that higher rates risk further weakening already subdued consumer demand.
For many households, that means another round of pressure on mortgage payments, credit costs and discretionary spending.
Middle East Conflict Continues To Shape Outlook
A recurring theme throughout the report is the impact of instability in the Middle East.
Kiwibank economists repeatedly point to oil prices and uncertainty surrounding shipping routes through the Strait of Hormuz as key risks facing the global economy.
The report argues that many of New Zealand's inflation challenges are increasingly being driven by global supply factors rather than excessive domestic demand.
As a result, higher interest rates may do little to address the underlying causes of rising costs.
Budget Forecasts Depend On Strong Recovery
The report also examines the Government's 2026 Budget and notes that Treasury is forecasting a significant economic rebound over the next several years.
Under Treasury's projections:
- Inflation peaks at 4.0% before falling sharply.
- Economic growth accelerates through 2027 and beyond.
- Unemployment declines from 5.5% to 4.3%.
- Government accounts return to surplus by 2028/29.
- Government debt begins to stabilise and fall.
Kiwibank, however, appears considerably less optimistic.
The bank notes that many of these forecasts rely on assumptions that oil prices fall, global conditions improve and international conflicts ease.
Those assumptions may ultimately prove correct, but the bank cautions that significant uncertainty remains.
Infrastructure, Health And Education Spending
Budget spending priorities identified by Kiwibank include:
- $5.8 billion allocated to health services and infrastructure.
- Continued investment in roads, including the Cambridge to Piarere Expressway.
- Additional support for vocational and trade training.
- Ongoing preparation for the financial impacts of an ageing population.
The report notes that New Zealand's superannuation costs alone are expected to rise from $26.5 billion this year to more than $31 billion by 2030.
Markets Prepare For Higher Rates
Financial markets have already begun adjusting to the possibility of future OCR increases.
Interest rates across wholesale markets have risen, while the New Zealand dollar strengthened following the Reserve Bank's updated outlook.
Currency traders now expect New Zealand interest rates to remain higher than previously anticipated, helping support the Kiwi dollar against both the US dollar and Australian dollar.
What It Means For Everyday New Zealanders
For most New Zealanders, the debate comes down to a simple question.
Will higher interest rates solve the country's inflation problem, or will they simply add another cost burden to households already struggling with rising prices?
Kiwibank's economists appear unconvinced that additional rate hikes are the answer.
Their concern is that policymakers may be attempting to fight supply-driven inflation with tools designed to cool consumer demand.
If they are right, borrowers could face higher mortgage costs while the underlying drivers of inflation remain largely untouched.
For now, attention turns to the Reserve Bank's July meeting, where the possibility of New Zealand's first rate increase in this cycle appears increasingly likely.
Whether that proves to be a necessary step or a costly mistake may become one of the defining economic questions of 2026.
