Today's figures show New Zealand's terms of trade with China, the country's biggest trading partner, rose 13 per cent in the December quarter, with export prices up 7.7 per cent and import prices down 5 per cent. The volume of exports rose 29 per cent while values were up 39 per cent, due to the pick-up in sales of dairy products, while import volumes increased 6.9 per cent for a 1.6 per cent rise in volumes.
The country's terms of trade were at their highest level since June 2014, when the measure enjoyed a 40-year high during the dairy boom, although it's still 3.7 per cent below that peak.
ASB Bank economist Nathan Penny said the terms of trade were ahead of expectations, reflecting the surge in dairy prices, and that the upside surprise was largely from the fall in import prices.
Indeed, the import price deflation trend remains in play, with six out of the nine categories posting fall," Penny said in a note. "Although notably, petroleum and petroleum products did post a 0.6 per cent lift over the quarter."
Still, ASB doesn't expect the data will move the Reserve Bank, and the economics team doesn't anticipate a hike in the official cash rate until late 2018.
The services terms of trade rose 2.5 per cent in the fourth quarter.
