The level of the New Zealand dollar is unjustified and unsustainable and it is susceptible to a significant downward adjustment over the next six to nine months, Reserve Bank Governor Graeme Wheeler says.
In a statement released by the Reserve Bank, Wheeler said the level of the dollar is unjustified when it is inconsistent with the economic factors that typically explain its movement during a business cycle.
Wheeler's comments pushed the New Zealand dollar below US80 cents to US79.99c, its lowest level since Sep 9, 2013.
“The Bank’s analysis indicates that the real exchange rate is well above its sustainable level, and also above levels justified by short-term business cycle factors,” Wheeler said.
“Unjustified and unsustainable are important considerations in assessing whether exchange rate intervention is feasible. Another consideration is whether conditions in the foreign exchange markets are conducive to intervention having an impact on the exchange rate."
“The real exchange rate has not adjusted materially to the recent downward movement in commodity prices. For example, global dairy prices have fallen by 45% since February 2014. Despite this, in August, New Zealand’s real effective exchange rate was 1% higher than its February 2014 level," said Wheeler.
"Past experience suggests that when the New Zealand dollar begins depreciating from an unjustified and unsustainable level, the ultimate adjustment can be large."
The New Zealand dollar is at exceptional historical levels, Wheeler said, noting the Trade Weighted Index (TWI) is above its 90th percentile calculated from historical data.
"Relative to the US dollar, Japanese yen and the euro the exchange rate is above the 90th percentile. It is close to the 90th percentile against sterling and the Australian dollar."
However, Wheeler said that past experience suggests when the New Zealand dollar begins declining from an unjustified and unsustainable level, the ultimate adjustment can be significant. He also said the Reserve Bank would welcome a move towards a more sustainable exchange rate level.
He said several factors could cause a change in financial market sentiment. These include a deterioration in global risk appetite, further falls in New Zealand’s commodity export prices, a slowing in New Zealand’s or China’s economic growth, and stronger indicators of economic growth in the United States.
"Under the current US outlook, the Federal Reserve is expected to start raising interest rates in the second or third quarters of next year. A stronger outlook for the US economy would likely trigger greater investor flows into the US dollar on the expectation that the Federal Reserve would begin to tighten sooner," said Wheeler.
"In the Reserve Bank’s view, the combination of these factors makes the New Zealand dollar susceptible to a significant downward adjustment over the coming six to nine months. Such an adjustment would be welcomed by the Bank as a move towards a more sustainable exchange rate level."
Here's the conclusion from the Reserve Bank's statement in full
Our modelling work indicates that the real effective exchange rate is above the level that can be justified by cyclical economic variables and that its current level is unsustainable over the longer term.
The nominal TWI is currently 4 percent below the historical high reached in July 2014. This decline in the TWI is small in relation to the 45 percent fall in global dairy prices since February 2014. We expect a significant further depreciation of the exchange rate as a result of the weakening in price of our dairy and log exports.
Past experience suggests that when the New Zealand dollar begins depreciating from an unjustified and unsustainable level, the ultimate adjustment can be large. Some of this reflects the limited overall liquidity in the New Zealand dollar markets, and the potential for pricing discontinuities when overall investor sentiment changes markedly and investors cut or exit their positions in volume.
Several factors could cause such a change in financial market sentiment. These include a deterioration in global risk appetite as the result of an adverse economic or geo-political shock, further declines in New Zealand’s commodity export prices, a slowing in New Zealand’s or China’s economic growth, and stronger indicators of economic growth in the US. Under the current US outlook, the Federal Reserve is expected to start raising interest rates in the second or third quarters of next year. A stronger outlook for the US economy would likely trigger greater investor flows into the US dollar on the expectation that the Federal Reserve would begin to tighten sooner.
In the Reserve Bank’s view, the combination of these factors makes the New Zealand dollar susceptible to a significant downward adjustment over the coming six to nine months. Such an adjustment would be welcomed by the Bank as a move towards a more sustainable exchange rate level.
