Traders are now betting the central bank will cut 6 basis points from the OCR in the coming 12 months, according to the Overnight Index Swap curve. Because the RBNZ moves in 25 basis point lots, that means the market is giving Bollard an outside chance of cutting rates over that period.
"Continued strength in the NZD could lead the RBNZ to flatten its proposed rate trajectory, or even cut rates," Martin said.
Traders also ignored Finance Minister Bill English's warning that the government's books have deteriorated, with early budget estimates of an operating deficit of $670 million in the 2014/15 year, when the government pledged to get the books back in the black.
English reaffirmed the government's commitment to reaching surplus, and said this year's zero budget will likely be followed by another year of little or no new spending in 2013.
The New Zealand Debt Management Office will hold its biggest auction in seven months today, when it tries to sell $900 million of debt. The DMO has a target of $13.5 billion of debt sales this fiscal year but has slipped behind the run rate needed to meet that total by June 30.
Martin said demand "should be supported by the continued spread of NZ bond yields to offshore equivalents."
No local data is scheduled for today, and investors will be looking for any suggestion of more quantitative easing when the Bank of Japan reviews monetary policy today.
