If, as expected, Reserve Bank Governor Alan Bollard leaves the official cash rate on hold at 2.5 per cent tomorrow, it will probably be the right call, according to a panel of economists and business leaders set up by the New Zealand Institute of Economic Research.
Modelled on a similar exercise run by the Australian National University's Centre for Applied Macro-economic Analysis, the NZIER Shadow Board's nine members are asked to give a percentage value for how much they prefer each interest rate the central bank might go for.
The results are then aggregated to provide a collective board view, which gives an indication of how convinced they are of their preferred view and also how they see the distribution of risks around it.
The shadow board's first such judgment put a 68 per cent probability on no change being the most appropriate call, but the risks were distinctly skewed to the downside, with a 16 per cent weighting for a 25-basis-point cut and 10 per cent for a 50-basis-point cut.
Kirdan Lees, a former Reserve Bank economist now with the institute who has set up the project, puts the case for a probabilistic indicator like this: "Monetary policy is rife with uncertainty. The state of the cycle is imprecise, how the economy evolves unsure, and the trade-offs across monetary policy objectives up for grabs. This means a range of possible policy settings might be appropriate at any point in time."
