Westpac Reduces 2026 Year-End Forecast for NZD/USD

Westpac Reduces 2026 Year-End Forecast for NZD/USD

 Published: October 21st, 2026

Australian bank Westpac has pared back its year-end forecast for the New Zealand dollar against the US Dollar from 0.588 to 0.56, pointing to higher energy prices and softening domestic growth.

The updated outlook reinforces the headwinds facing the Kiwi, which remains vulnerable to rising import costs and uncertainty over the Reserve Bank of New Zealand's (RBNZ) next move. Westpac sees NZD/USD recovering towards 0.64 during 2027. New Zealand's currency faces a difficult combination of expensive imports, weaker household spending and a softening growth outlook.

The antipodean nation imports almost all its fuel, leaving its economy exposed when crude prices rise. With Brent crude at close to $110 a barrel, the cost of imported energy acts as a drag on trade and leaves households with less money to spend on extras. A weaker New Zealand dollar compounds the problem by making each barrel more expensive in local money.

Retail activity is already showing signs of strain. Electronic card spending fell 0.4% in September, extending August's 0.9% decline, according to the most recent government figures. Higher fuel prices have squeezed spending elsewhere, adding to concerns about the domestic economy.

NZD's trade-weighted index has fallen to a 17-year low, underscoring the extent of its recent weakness.

Westpac is looking for the NZD/USD pair to end 2026 at around 0.56, roughly three US cents below its previous forecast. Its projection for a recovery towards 0.63 in 2027 rests on interest-rate differentials with the US gradually narrowing and a softer US dollar.

There is, however, a counterargument. A note from Corpay estimates that the New Zealand dollar is trading three to four cents below its fair value. The firm expects resilient growth, elevated agricultural prices and further RBNZ rate increases to support the currency over the medium term.

That leaves investors weighing immediate economic pressures against the prospect of a recovery once the current headwinds ease.

The Kiwi's Energy Bill Comes Due

On the Sterling front, GBP/NZD has spent October trading beneath 2.3667, a level that has capped the exchange rate on three occasions acros the month.

Corpay analysts say repeated failures at the same price suggest that sellers remain active around this threshold. A daily close above 2.3669 would signal that the resistance has finally given way, potentially clearing the path towards fresh multi-year highs.

The Kiwi's performance this past Friday, 16 October, offered a reminder that currency markets can turn quickly. NZD was the G10's top performer on the day, gaining across the board as the US Dollar retreated and expectations of an RBNZ rate increase strengthened.

The currency is particularly sensitive to movements in the greenback. A softer US dollar can provide the Kiwi with rapid relief, even when domestic economic conditions remain challenging.

Falling equity markets would ordinarily pull on the New Zealand Dollar. Yet concerns about artificial-intelligence spending also pushed US Treasury yields four to nine basis points down, weighing on the greenback.

Whether NZD's rebound lasts will depend partly on how the sell-off in equities plays out and the direction of US yields. A sustained recovery in the Dollar could quickly restore pressure on NZD/USD.

The RBNZ's October Decision Is Wide Open

Domestic monetary policy presents another complication for the Kiwi. In an interview with Bloomberg, the RBNZ's Chief Economist suggested that upside risks to inflation had increased, describing the central bank's pending late October decision as “wide open”.

A note from Brown Brothers Harriman says traders have priced in an 80% probability of a 25-basis-point increase at the meeting, or 3%. Much of the outlook is therefore reflected in current prices, leaving the currency exposed if incoming data disappoints.

The key test arrives on Thursday, when New Zealand publishes its third-quarter consumer price index. Consensus forecasts point to inflation of 3.8% year-on-year, down from 4.2%.

A stronger-than-expected reading would reinforce expectations of tighter monetary policy and could be a tailwind for the Kiwi. A softer result would raise questions about the need for an immediate increase, particularly with household spending weakening.

The Reserve Bank's decision remains contested among local forecasters. Barclay's expects increases this month and again in December, which would take the official cash rate to 3.25% by year-end. Westpac expects the central bank to pause in October, highlighting the uncertainty surrounding the next policy move.

Barclay's also sees an October increase as a live possibility, even if inflation undershoots the RBNZ's own forecast. The bank argues that the Autumn combination of weaker currency and rising oil prices have altered the outlook, firming up the case for action.

Observing Regional Signals

Events in Australia offer an indication of the pressures affecting the region's wider currency complex. Australian employment sank by 40,000 in September and unemployment rose to 4.68%, muting expectations of a November Reserve Bank of Australia rate increase. The Australian dollar and New Zealand dollar often respond to similar shifts in global risk appetite, although their domestic policy outlooks can diverge.

Energy markets also warrant attention. The International Energy Agency's decision to free up some 100 million barrels of oil has eased some supply concerns, offering potential relief to fuel-importing economies such as New Zealand. The durability of that relief will depend on the path of crude prices.

Corpay also warns that the Greenback could become more volatile if Federal Reserve Chair Warsh reiterates the case for tighter monetary policy. Its technical levels for NZD/USD stand at resistance around 0.5700 and support near 0.5579.

The Kiwi has demonstrated that it can rebound sharply when the dollar weakens. Its underlying economic pressures, however, remain substantial. With the RBNZ decision approaching and the market already leaning towards a rate increase, sterling's path of least resistance still points higher, provided GBP/NZD can clear October's stubborn ceiling.
