New Zealand Faces Economic Warning as Moody’s Downgrades Outlook and Govt Reveals Oil Shock Scenarios

New Zealand’s Finance Minister Nicola Willis has revealed that the government has developed three economic scenarios to assess the potential impact of ongoing Middle East oil supply disruptions on the country’s recovery, emphasizing that while the crisis may delay growth, it will not derail the economy.

Speaking at a media briefing in her Beehive office on Thursday, April 23, 2026, Willis explained that Treasury had reopened its economic forecasts ahead of next month’s Budget due to heightened volatility in global energy markets following the escalation of conflict in the region. The scenario analysis, developed last month, models outcomes ranging from a short-term disruption with oil prices at US$110 per barrel to a severe, prolonged shock pushing Brent crude to US$180 per barrel.

Under the mildest scenario, which Willis said appears most likely given current Brent crude prices of US$102, inflation would rise to 3.9%, economic growth would slow to 2% and unemployment would reach 5.3%. In the worst-case scenario, which would require oil prices to nearly double from current levels, inflation could spike to 7.4% and unemployment climb to 6.6% by mid-2027.

Willis stressed that the scenarios are not forecasts but planning tools, stating: “It’s important to note that these scenarios are about what might happen. They are not forecasts of what Treasury think will happen.” She added that the government’s position remains that the economy has been disrupted but not derailed and will continue to grow this year.

The revelation comes hours after Moody’s Investors Service downgraded its outlook for New Zealand’s economy from stable to negative while affirming the country’s AAA credit rating. The agency cited global economic and political uncertainty, persistent inflation pressures—including fuel price increases, stubborn non-tradeable housing costs, and utility prices—and higher electricity costs as key factors behind the decision.

Moody’s also noted New Zealand’s delayed return to a budget surplus and the increased debt burden from recent shocks, which have added pressure to the fiscal outlook. The agency emphasized that while strong institutions and policy frameworks support the AAA rating, weaker growth, tight monetary policy, and higher debt servicing costs present ongoing challenges.

This marks the second major credit outlook warning for New Zealand this year, following a similar move by Fitch Ratings in March, which lowered its outlook to negative from stable due to increasing difficulty in reducing debt amid delayed fiscal consolidation. Finance Minister Nicola Willis acknowledged the downgrades as a signal that the government must maintain fiscal discipline, stating: “Global economic and geopolitical uncertainty and inflation pressures, including fuel price increases, have contributed to the revision. While these are outside our control, Moody’s are clear that improving our rating requires disciplined spending, a clear path to balanced books and reducing debt.”

Willis further highlighted that debt servicing has now become the government’s fourth-largest expenditure, exceeding the combined costs of the police and defence forces, Corrections, Customs, and the justice system. She warned that with global interest rates rising, maintaining fiscal order is essential to ensure New Zealand remains resilient in a more unstable world.
