Cash rate to rise tomorrow: how many RBA hikes can you avoid by refinancing?

The Reserve Bank is set to fire off another cash rate hike tomorrow, with a 0.50 percentage point increase the most likely outcome.

As RateCity.com.au noted on Thursday, a 0.50 percentage point hike will see the average variable borrower’s monthly repayments rise by $144, assuming banks pass on the hike in full to customers (see table below).

However, a rate hike tomorrow will be the fifth time the Board has lifted rates since May. For an owner-occupier with a $500,000 debt at the start of the hikes and 25 years remaining on their loan, the total increase to their monthly repayments could be $614.

How many hikes can you prevent by refinancing?

The rate hikes aren’t likely to end tomorrow. Westpac is forecasting the cash rate will get to 3.35 per cent by February next year – a total increase from today of 1.50 percentage points.

The average existing variable owner-occupier borrower is paying 4.61 per cent, while the lowest variable rate is currently 3.24 per cent.

If this borrower refinanced to the lowest rate, they would be pocketing a 1.37 percentage point rate cut, mitigating the vast majority of these forecasted hikes. This assumes lenders pass on future rate hikes in full.

RateCity.com.au, research director, Sally Tindall said, “While we’re likely to be well over the half-way mark, the RBA has at least two, but potentially as many as five, rate hikes still in its sights.”

“The average borrower could see their variable rate rise to over 6 per cent in a matter of months, unless they take action,” she said.

“People on a variable rate might feel powerless right now, but that doesn’t have to be the case. Refinancing to a more competitive rate will help mitigate future RBA hikes.

“Switching to the lowest variable rate might seem like hard work but it can translate into over $6000 in savings in the first year alone, for someone with a $500,000 loan and 25 years remaining.

“Don’t wait until the cash rate hits 3.35 per cent. Act now, because the sooner you refinance, the more money you’re likely to save,” she said.
