The Labour Party's plan to use changes to Kiwisaver contribution rates rather than interest rate hikes to take steam out of consumer spending would act as an inadvertent boost to house prices, according to BNZ chief economist Tony Alexander.
In his latest Weekly Overview Alexander said that under the proposals as outlined by Labour this week, the risk of having a large mortgage that is posed by the potential for high interest rates would be reduced. Therefore this would likely push up house prices as people could buy houses less worried by the prospect of very high interest rates.
"Additionally, because of lower average borrowing costs and because of reduced returns on the likes of term deposits plus the increased volatility in share prices we would expect to see more investors divert toward residential property.
"This would again tend to boost house prices, reduce home affordability, and again bias the housing market against young buyers, Alexander said.
He thought there might also be implications for the housing market in Labour's proposals to put the brakes on immigration - a move in part targeted at taking the pressure off the housing market.
"This sounds like a good idea, but this is why we economists spend years at university," Alexander said.
"We learn that if you base policy on one obvious relationship between two variables you will probably make your macroeconomy worse because you are missing all the other linkages.
"To whit.... if you cut immigration when your economy is strong you risk boosting inflation overall because you will reduce labour supply and push wages higher.
"Reduced house construction in particular will push house prices higher and work to offset the price effect of decelerated population growth," Alexander said.
He questioned whether migration had actually been pushing Auckland house prices in particular higher.
"Not at all," he said.
"Auckland house prices rose by 38% between January 2009 and July last year. It was in July that the net annual migration flow for NZ rose above the ten year average of 10,000 people on its way to the latest reading near 32,000.
"Thus prices soared during a period of below average migration gains."
He reiterated that what Auckland needed was more houses "and for that it needs more of lots of things including land and builders".
"Restricting immigration may have the opposite effect to what Labour intend."
Alexander said "good on" Labour for showing a willingness to look for solutions to their identified problems.
"But just as subsuming Kiwisaver's focus on building retirement savings over the long term to the dictates of monetary policy under the control of the Reserve Bank is a bad idea, so too is making migration policy a slave to the monetary policy cycle."
