The Reserve Bank believes the New Zealand dollar is unsustainably and extremely high, but it is not currently considering intervening to pull it down because the market is too liquid and a lower currency would clash with its aim of tightening monetary policy to contain inflation.
Reserve Bank Deputy Governor Grant Spencer said in an interview currency market intervention remained an option and he explained the bank's 'traffic light' system for considering intervention. The system requires the bank to be sure the currency is extreme, unsustainable and that any intervention was consistent with current monetary policy. Any intervention would also have to have an impact by catching the market 'off guard' at times of volatile and illiquid trading.
Spencer said the bank did see the New Zealand dollar as extremely and unsustainably high, but that the foreign exchange market was currently very liquid and monetary policy was being tightened so a sharply lower currency would clash with the bank's aim of lowering inflationary pressure. He was speaking on Thursday afternoon as the New Zealand dollar was rising to a record post-float high of 80 on the Trade Weighted Index.
"Intervention is of course an option for us and we keep that policy open. We have a traffic light system and we have to have some view that we would have some impact," Spencer said.
"You can't move against the tide, but in some situations it may be more opportune to do so," he said.
"The strength of the currency right now, as Graeme was saying, is pretty widespread. It's not particularly volatile. There's more opportunity to intervene effectively in spike situations."
The Reserve Bank of Australia's 'jawboned' the Australian dollar down from over 95 USc to 87 USc in November and December last year when Governor Glenn Stevens said he wanted the currency closer to 85 USc than 95 USc and had not ruled out intervention. It has since bounced somewhat to 90 USc.
Earlier on Thursday in a news conference after releasing the bank's March Quarter Monetary Policy Statement, Governor Graeme Wheeler was asked about the prospects for New Zealand dollar intervention. He downplayed the effectiveness of such intervention given the large volumes of trade in the New Zealand dollar on offshore markets. The Reserve Bank of New Zealand intervened to sell down NZ$4 billion of the New Zealand dollar in mid 2007 and early 2008, making profits of over NZ$400 million in the following three years, this RBNZ paper published in 2012 shows (pg 15)
Spencer said in the interview the New Zealand dollar had met two of the four 'traffic lights' for intervention. It was unsustainably high and extreme, and was a headwind for exporters, but the timing for intervention was not currently right.
"Even though we may think it's unsustainable, we may not think it's opportune. Relative to history, it is near record levels so you'd tick that box. It's extreme and unsustainable. Then there's the question of 'Is it consistent with policy?'" he said.
"If you tighten monetary policy, does it make sense to intervene at the same time? Probably not."
The Reserve Bank hiked the Official Cash Rate by 25 basis points to 2.75% and forecast short term rates were likely to rise a further 250 basis points by early 2017 as it moved to dampen inflationary pressures generated by an economy growing faster than potential. That forecast includes an assumption of only a gradual fall in the New Zealand dollar TWI to 75 by 2017. A steep drop in the New Zealand dollar would add to inflationary pressures.
"It's true that a high currency pushes inflation down, but we're well aware of the distortions that can cause as well, making it more difficult for the traded sector to be competitive. We would prefer to see a lower currency, even though that might have some price effects," Spencer said.
"It would be pretty unusual for us to be intervening right on top of a tightening, but the other thing it's linked to is the proposition that it's opportune: which is about market liquidity, the extent to which there's two way flows, the amount of volatility, the nuts and bolts of being in the market. There are certain situations where you're potentially going to have more impact," he said.
'NZ$100 billion a day traded'
Earlier Wheeler was asked whether the rate hike would increase the upward pressure on the New Zealand dollar.
"It's true we're leading the tightening phase among the advanced economies and it's true that our exchange rate is high by historic standards on a TWI basis, and against most of the major bi-lateral crosses," Wheeler said, noting it was within the top 10% of past historical experiences.
He said New Zealand's near record high terms of trade was a major reason for the strength and there was a strong correlation between the two. He also noted that countries producing two thirds of the world's output had interest rates between 0 and 1%, which was likely to continue for some time.
"The exchange rate pressures are a concern for us, but we also feel that we've telegraphed these moves quite carefully," Wheeler said.
"I don't think it's any surprise to the market and most institutional investors are anticipating this sort of tightening, and therefore we're not expecting any significant exchange rate increase as a result."
The New Zealand dollar rose around 1 USc to almost 86 USc later on Thursday. Some economists cited the Reserve Bank's comments about not intervening as a factor in the rise.
Wheeler was then asked if the economy would have to live with the high currency.
"That's the truth. That's exactly what we do have to live with. There are clearly negative effects in terms of headwinds in the tradeable sector for exports and import substitution industries and particularly those exporters exporting to Australia, therefore manufacturing exporters. Commodity exporters have had the benefit of the terms of trade increase," Wheeler said.
"But we live in a world where our currency is between the 7th and 10th most traded currency internationally. Daily turnover in the foreign currency markets is around NZ$100 billion. About 90% of that takes place offshore. Our currency is enormously, intensively traded. To give a benchmark: If you've got daily turnover of NZ$100 billion a day, New Zealand's GDP is about NZ$180 billion to NZ$200 billion."
Asked specifically about the prospect of intervention, Wheeler said: "Daily turnover on the FX markets are around NZ$100 billion. Most in NZ$/US and 85-90% offshore. The opportunities for intervention, given those sorts of flows, are extremely limited."
