If you’re paying off a mortgage – or aspiring to – imagine if you didn’t have to worry so much about rising interest rates.
That’s already the reality for US home buyers. Unlike in Australia, most mortgages in the US have a fixed-interest rate, locked in for 30 years.
Instead of having to wait and see if their central bank (the Federal Reserve) raises rates each month, a US 30-year fixed mortgage at 2 per cent will still have the same monthly repayment – even after a rate rise.
In contrast, when the Reserve Bank of Australia (RBA) lifts rates it has huge implications for household budgets, because most borrowers still have variable-rate mortgages.
Every time the cash rate increases and banks inevitably pass through that increase, our mortgage payments go up too – adding thousands of dollars to average annual repayments.
This is one reason why RBA governor Philip Lowe has been so cautious about following the US Federal Reserve’s strong signal about lifting interest rates.
So why don’t Australian lenders offer 30-year fixed-rate mortgages too, like their US counterparts?
Every extra 1 per cent can cost thousands
Here in Australia, an extra 1 per cent on a A$600,000 mortgage means $6,000 a year more in interest payments. And these are post-tax dollars. So if you earn $100,000 and hence pay an average tax rate of 25 per cent, that’s like taking a roughly $8,000 pay cut. Ouch.
A 3 per cent rise in official rates over two to three years is not impossible. On a $600,000 mortgage that would mean an extra $18,000 a year in interest payments.
The RBA knows this, of course. It looks at Australian household debt of more than 120 per cent of GDP and knows raising rates too aggressively risks putting a significant number of Australian households into financial distress.
In one sense this is good news. It means the RBA has large-calibre ammunition to fire in pursuit of its monetary policy goals (to keep unemployment low and inflation between 2 per cent and 3 per cent).
But it would be better if the Australian mortgage market involved less risk for consumers.
There is no reason why Australian lenders couldn’t offer 30-year fixed-rate mortgages. After all, there’s an active government bond market with maturities from one year to 30 years. This provides a benchmark to price mortgages.
Two fixes for more affordable mortgages
Fixed-rate mortgages have become much more popular in Australia in the past few years: the proportion of new mortgages that were fixed jumped from about 15 per cent in June 2019 to more than 45 per cent by September 2021.
