The New Zealand dollar fell amid expectations China will retaliate for the latest tariffs the US has announced on Chinese imports, which has weighed on prices of commodities and commodity-linked currencies.
The kiwi fell to 67.60 US cents as at 5pm in Wellington and earlier touched 67.46 cents, the lowest in more than a week, from 68.09 cents late yesterday. The trade-weighted index declined to 72.45 from 72.79 yesterday.
The New Zealand and Australian dollars have fallen in the wake of renewed trade war fears between the US and China, their biggest export market.
Raw materials - dairy, coal and iron ore - dominate exports from the ANZ region and the CRB index of 19 commonly traded commodities fell 2.8 per cent overnight.
China, the world's biggest buyer of commodities, has vowed to retaliate, although it doesn't buy enough from the US to match it dollar for dollar.
"The market is expecting China is going to retaliate. I don't see them backing down," said Mitchell McIntyre, a dealer at HiFX. "That's why we've seen a bit of risk aversion over the past 24 hours."
McIntyre said a current support level for the New Zealand dollar at around 67.50 US cents is "holding for the time being."
The kiwi didn't move much after figures showed food prices rose 0.2 per cent in June, which the government statistician attributed to an increase in the minimum wage.
The food price index was released ahead of June quarter CPI, which Westpac Banking Corp is expecting to show a 0.6 per cent increase in prices in the quarter for an annual gain of 1.7 per cent.
Economists at ASB bank said in a report today that increases in New Zealand's minimum wage and a move to collective bargaining will stoke wages and inflation over the next five years.
Tonight, the main focus may be the release of US CPI inflation, seen at 0.2 per cent month-on-month in June for a year-on-year increase of 2.9 per cent, up from 2.8 per cent previously.
The kiwi dollar rose to 75.78 yen from 75.60 yen yesterday. It rose to 4.5182 yuan from 4.5367 yuan and fell to 91.53 Australian cents from 91.85 cents. The kiwi fell to 51.14 British pence from 51.35 pence and declined to 57.82 euro cents from 58.05 cents.
New Zealand's two-year swap rate fell 1 basis points to 2.16 per cent and 10-year swaps were unchanged at 3.02 per cent.
