Goldman says Swedish, Kiwi markets most at risk of bust

G10 ECONOMIES

MATTHEW BROCKETT The Swedish and New Zealand housing markets are the most at risk of a correction among the so-called G-10 economies, according to Goldman Sachs.

In a report on house prices in G10 nations — those with the 10 most-traded currencies in the world — Goldman finds they are most elevated in small, open economies such as Sweden and New Zealand. The investment bank said there is a 35 per cent to 40 per cent chance of a housing “bust” in each country over the next two years, which it defines as house prices falling five per cent or more after adjustment for inflation.

Goldman compares houseprice levels across economies using three standard metrics: the ratio of house prices to rent, the ratio of house prices to household income and house prices adjusted for inflation.

“Using an average of these measures, house prices in New Zealand appear the most over-valued, followed by Canada, Sweden, Australia and Norway,” it said. “According to the model, the probability of a housing bust over the next five to eight quarters is the highest in Sweden and New Zealand at 35 to 40 per cent.”

A graph in the report shows that New Zealand’s probability of a housing bust is just above 40 per cent, while Sweden’s is just above 35 per cent. The risk of a bust in Canada is about 30 per cent, while in Norway, Australia and Switzerland the probability is assessed at 2025 per cent.

New Zealand house prices have surged 60 per cent since 2010, while Sweden’s have risen 41 per cent, according to data compiled by the Bank for International Settlements. New Zealand’s central bank last week forecast houseprice inflation would slow to five per cent this year from 14 per cent in 2016, but remain positive through mid-2020.

Goldman said the pace of credit growth over the prior five years is an important indicator of asset-price busts. Its housing bust model also includes the house price-torent ratio, past changes in real house prices, the investment-to-GDP ratio, real GDP growth, and inflation.

“The probability of a house-price bust has been picking up across the smaller G-10 markets in recent years — a result of rising prices and high credit growth,” it said.

While residential investment in Sweden and New Zealand are high, immigration booms and population growth in both countries are supporting construction demand, Goldman said. “In contrast, Australia, Norway, and Canada appear overbuilt,” with homebuilding activity
