While markets have for some time been pricing in Official Cash Rate cuts for this year, recent inflation data and a monetary policy announcement have given them reason to price in even more aggressive reductions.
Consumers Price Index data shows inflation was 3.3% in the year to June 30 compared with a 4% increase in the 12 months to the March 2024 quarter.
The headline annual inflation figure came in below the RBNZ’s expectations of 3.6%.
And while the RBNZ kept the OCR on hold last week at 5.5% — the eighth consecutive time — it was more dovish in its tone.
The monetary policy committee noted risks that interest rate pain may be feeding through to the domestic economy “more strongly than expected”.
Former Reserve Bank head of financial markets Michael Reddell told Newstalk ZB the statement “was a real lurch”.
“It was very different in tone from the statement they brought out only six weeks ago, which was talking up possible rate hikes later this year and not even beginning to cut until August next year,” Reddell said.
“It’s all over the place, but a shift in the right direction.”
