Christian Hawkesby: Accurate GDP forecast would’ve altered May RBNZ policy

Deputy Governor Christian Hawkesby says the Reserve Bank's (RBNZ) Monetary Policy Committee might have taken a different stance in May if the economic activity forecasts had been more accurate.

In May, forecasts had anticipated 1% GDP growth for the calendar year. But by August, that had been revised to a 0.4% contraction, with a deep decline in the June quarter.

The RBNZ chose to cut the Official Cash Rate from 5.50% to 5.25% last Wednesday partly in response to these lower economic activity forecasts.

Another key factor was that businesses have been adjusting their wage and price-setting behaviour more quickly than anticipated in response to the low inflation environment.

Speaking in the latest episode of interest.co.nz's Of Interest podcast, Hawkesby said the committee would not have adopted such a hawkish stance if these data points had been available during the May meeting.

“The uncertainty was around the speed and intensity that [tight policy] would be felt in the economy … Since then we've had a whole heap of evidence on the downside playing out”. 

Uncertain

He said the OCR projection, published in that Monetary Policy Statement, was “flat with a slight upward bias” but with “big uncertainties” that were outlined in the record of meeting.

Weaker than forecast GDP was not cited as a risk in the May meeting record, and uncertainty about price-setting behaviour was described as an upside risk. The committee agreed that interest rates need to “remain at a restrictive level for a sustained period.”

The chapter on economic projections included a disclaimer that said there was “significant uncertainty” about the assumptions used in the baseline forecasts. But the possibility of easing rates in the near future was not mentioned in the 60-page document.

This shift led some economists to describe the August decision as a 'U-turn.' However, there was consensus that it was the correct move, given the clear signs of a weakening economy.

Stay off the track

Hawkesby also said there had been a “misconception” that the central bank was going to keep the OCR at 5.50% until it saw inflation below 3%. 

“You need to work on the basis that monetary policy is going to work. You don’t have to wait until the number is within the band, you just have to have confidence it will settle there.” 

However, the May monetary policy statement projected the OCR would remain above 5.50% until September 2025, by which time inflation would have been below 3% for a full year.

This was true in the February 2024 and November 2023 monetary policy statements as well. 

Hawkesby said the OCR track that published in each statement often gets overanalyzed, without enough recognition that it is based on a set of assumptions.

“There's something quite peculiar that happens when someone sees a line on a chart, or they see a number in a table, it has this sense of
