Reserve Bank governor Alan Bollard has fired a shot across the bows of the foreign exchange market, warning that if the exchange rate remains strong, without anything else changing, he would need to reassess the outlook for monetary policy settings.
The comment came in the release of the bank's official cash rate review which, as universally expected, left it on hold at its all-time low of 2.5 per cent.
Six weeks ago he said that sustained strength in the New Zealand dollar would reduce the need for future increase in the OCR. That accompanied forecasts which pencilled in hardly any increase in the OCR - just 25 basis points a year for the next three years.
Since then the kiwi dollar has not budged despite, as the governor points out today, recent falls in export commodity prices.
In New Zealand dollar terms those prices have fallen by 18 per cent over the past year - even before the latest Fonterra auction at which dairy prices dropped with a thud - but the exchange rate has shrugged it off.
