The New Zealand dollar surged against other currencies after the Reserve Bank governor Graeme Wheeler raised the official cash rate for a third time as expected and kept projected interest rate rises in line with his March projections.
The kiwi rose to 86.50 US cents at 5pm in Wellington from 85.53 cents at 8am and 85.48 at 5pm yesterday. The trade-weighted index advanced to 80.69 from 79.79.
Wheeler hiked the OCR a quarter-point to 3.25 percent, his third increase since he began his tightening cycle in March in a bid to fend off inflationary pressures. The governor gave no indication of a slower pace for further increases, thought the market has moderated its expectations for hikes in the OCR this year by about 15 basis points since March.
Traders had speculated weaker commodity prices, particularly a 23 percent drop in global dairy prices since the start of the year, would make the governor dovish.
The market was "massively surprised" by Wheeler's firm stance, said Imre Speizer, senior market strategist at Westpac Banking Corp.
