Standard & Poor's, the global credit rating agency, has put eight local banks on notice over the rising risk of a housing bubble bursting in New Zealand.
Smaller lenders Cooperative Bank, Heartland Bank, TSB Bank, Credit Union Baywide, Credit Union South, First Credit Union, New Zealand Association of Credit Unions and Police and Families Credit Union have all had their outlooks dropped to negative from stable, giving them a one-in-three chance of being downgraded in the next two years if the country's economy deteriorates, S&P said in a statement.
The outlook for bigger lenders, including ANZ Bank New Zealand, ASB Bank, Bank of New Zealand, Westpac New Zealand, Bank of India (New Zealand), Rabobank New Zealand and Kiwibank, was left unchanged due to expected support from their parents.
The rating agency said persistent current account deficits and a heating property market were threats to the New Zealand economy. New Zealand's current account deficit is forecast to keep widening to 6.5 per cent of gross domestic product by 2017 as trade surplus from exported goods falls in the wake of the drought and the deficit from imported services remains elevated.
"We consider that there is an increasing risk that a sharp correction in property prices could occur if there is a weakening in the country's macroeconomic factors," S&P said.
