"We expect the RBNZ to keep the OCR on hold, with the guidance likely to be similar to January's (which was repeated in Governor Wheeler's speech in February)," Westpac Bank market strategist Imre Speizer said in a note before the release. "We see potential for a market surprise from the magnitude of change in the 90-day interest rate forecast, a downgrade highly likely."
The Reserve Bank slashed its expectations for annual inflation, which it sees staying below 1 per cent until March next year, before rising to 1.7 per cent by early 2017. That was due largely to the slump in oil prices last year, which reduces input costs for local businesses, and the central bank said a more "significant reduction" in consumer prices it would "warrant more supportive monetary policy."
Wheeler said the bank is "closely monitoring" the impact of weak inflation expectations on wage and price setting behaviour, particularly in the non-tradeable sector.
"The bank lowered its neutral nominal 90 day interest rate assumption following the global financial crisis. However, it remains an open question whether these changes were sufficient to reflect developments in recent years, including the more recent signs that longer term inflation expectations have adjusted lower."
Prime Minister John Key this week said he expected inflation to fall further and that there was "potentially a scenario where it's not an option for the bank to raise interest rates," though he wouldn't be drawn on whether Wheeler should cut rates.
While inflation has dropped below the bank's target band at an annual pace of 0.8 per cent in 2014, the central bank has had contend with a resumption of rising house prices in Auckland, where supply hasn't managed to match demand.
The Reserve Bank last week announced plans to introduce a new asset class for residential investor loans, requiring higher capital ratios as a pre-cursor to potentially target macro-prudential tools.
The bank said the property market has tightened across the country since the middle of last year, though that was most pronounced in Auckland, where house price inflation is running at about 13 per cent. The bank expects house prices to rise 8 per cent in the year ending Sept. 30. Quotable Value figures this month showed property values rose at an annual pace of 6.4 per cent in February, the fastest pace in five months.
The Reserve Bank is more bullish on the domestic economy as a result of cheap oil, predicting gross domestic product growth of between 3 per cent and 4 per cent over the next two years, having previously estimated annual expansion of about 3 per cent in its December monetary policy statement.
Wheeler said the fall in oil prices "has increased households' purchasing power and lowered the cost of doing business," while employment and building activity remain strong, inbound migration is high and the housing market is picking up.
The currency is still a concern for the Reserve Bank, which Wheeler again said was "unjustifiably high and unsustainable" and that "a substantial downward correction in the real exchange rate was needed to put New Zealand's external accounts on a ore sustainable footing." The kiwi dollar has been on the decline in recent months as global investors heighten their expectations for higher US interest rates this year as the world's biggest economy continues to recover from the global financial crisis and subsequent recession.
The Reserve Bank expects the trade-weighted index to be at an average 77 in the March quarter of this year, edging down to 76.9 by the end of 2015. It had previously anticipated the TWI would be at 74.8 by the end of 2015.
