Alan Bollard’s decision to step down as governor in September has opened the doors for debate about how monetary policy is operated and speculation over who will be the next governor.
The following are what I believe to be the most important issues:
1. The need to avoid a new governor embarking on a monetary policy experiment like Bollard’s misguided and extremely costly “go for growth” experiment.
2. The need to recognise that interest rates are extremely powerful drivers of economic cycles. This means that excessive adjustments in the OCR imposes unnecessary and costly volatility on the economy and especially on interest rate sensitive industries like residential building.
3. The need to recognise the futility in the forecasting-based approach the RBNZ has used to make OCR decisions and monetary policy decisions before the birth of the OCR in 1999. The RBNZ needs to stop pretending it can predict the future with the degree of accuracy required to make quality, proactive adjustments in the OCR. Lacking the ability to forecast the future with any degree of accuracy the RBNZ resorts to reactive adjustments in the OCR that add to rather than reduce volatility in the economy, especially for interest rate sensitive industries.
4. The need for the RBNZ to focus more on assessing the neutral level of the OCR (i.e. the level consistent with keeping inflation low on average over the medium term) and on keeping the OCR relatively stable at around the assessed neutral level.
5. The need to remember that the primary reason for an independent central bank is to stand in the way of politicians abusing power (i.e. stop excessive use of taxpayers’ money to buy elections).
This Raving discusses these issues, some of which I have dealt with in detail in past Ravings and other reports.
Based on the insights provided by the brief discussion of these issues I make some recommendations (e.g. the type of new governor required, whether the governor or a committee should be responsible for OCR decisions).
