A new report by International Monetary Fund (IMF) shows rising interest rates bite harder in some countries than others – and it’s grim reading for Australian mortgage holders.

Globally, repayments have become increasingly difficult to meet on the back of rapid rate increases.

But the new IMF World Economic Outlook report shows that rate rises hurt Australians the most.

“It mightn’t come us a surprise too many Australians, but we are right at the top – we’re number one,” Australia Institute Chief Economist Greg Jericho said on the latest episode of Dollars & Sense.

“What it’s saying is that, if interest rates went up – let’s say by one per cent in every advanced economy in the world – Australians would feel that the most.”

The prevalence of variable home loans in Australia is one of the reasons rate increases are hitting harder, according to the IMF.

“In Australia, around 85 per cent of people with a mortgage have a variable rate of some kind. That’s actually really unusual,” Jericho said.

“In the United States, 95 per cent of people with a home loan have a fixed rate mortgage. In the United Kingdom, it’s 85 per cent.

“If you’ve got a 30-year fixed rate mortgage, you really don’t care what the Reserve Bank does.”

Other drivers identified by the IMF include high levels of household debt and looser lending guidelines, but Jericho said that soaring house prices also play a big role.

Since 2005, median house prices have gone up by 86 per cent globally, but Jericho’s analysis shows that prices have gone up 162 per cent in Australia over the same period.

“So, just a little bit different.

“I think you can make a pretty good case…that we have some damned expensive houses.

“Things have really taken a turn for the worse over the past five, 10, 15 years – nearly 20 years really.”

As for what the Reserve Bank of Australia might do from here, the market is predicting cuts over the next 12 months, but that might be optimistic, according to Jericho.

“If Australians are hurt more by interest rate rises than elsewhere, it means they also get the benefit of rate cuts more than elsewhere.

“So the Reserve Bank might be inclined to go, ‘yeah, let’s just wait and see’.”
