Mr Stevens comments followed years of speculation by critics that the level of home prices in Australia constituted a bubble, in the same vein as credit bubbles seen in the US and Europe in the years before the financial crisis.

In 2010, the US-based Centre for Economic and Policy Research co-director Dean Baker, one of the economists who forecast the financial crisis before 2007, said the Australian housing market looked like a bubble because rents didn't "remotely correspond" to house prices.

The Economist magazine reached a similar conclusion, as did US investment fund GMO manager Jeremy Grantham in 2010.

While discouraging explanations of future home price movements that relied on domestic factors solely, Mr Stevens today linked the increase in home prices to the global debt boom which was seen through the US, UK, and Europe since in the mid-1990s.

"As everyone knows, dwelling prices rose a great deal over the decade or more from 1995, and not just in Australia," he said. "This occurred globally."

The "widespread phenomenon...suggests that the global dwelling price dynamic had a lot to do with financial factors - and there is little doubt that finance for housing became more readily available."

The Anika Foundation Luncheon was supported by Australian Business Economists and Macquarie Bank. The speech, entitled "The Lucky Country" focused on whether Australia's relatively good economic performance in recent years is a function of "luck" or wise policy.
