Westpac follows ANZ’s lead with interest-only home loan rate increases

Westpac has increased rates on interest-only mortgages by 0.34%, following changes from fellow big bank ANZ which hiked interest-only rates by up to 0.30% earlier this month, in what is becoming a growing trend among home loan lenders.

Westpac’s rate increase applies to both investors and owner-occupiers, bringing the standard variable rate on interest-only lending up to 6.30% and 5.83% respectively, as of June 30.

On a $600,000 loan over a 25 year term, this 0.34% increase to 5.83% p.a. could cost a home buyer an extra $36,827 in interest, according to Mozo’s home loan repayment calculator.

On the other hand, rates on owner-occupier loans with principal and interest repayments were decreased by 0.08%, bringing the standard variable rate down to 5.24%. Given the same loan conditions as above - a $600,000 loan amount over 25 years - this represents a saving of $8,508.

The move was aimed at least in part to nudging customers toward making principal and interest repayments on their home loans instead of just paying down the interest, in response to APRA’s tightened regulations around “risky” lending, introduced earlier this year.

George Frazis, Chief Executive of Westpac Consumer Bank, said, “We hope the rate reduction will encourage owner occupier customers with interest only home loans to switch to principal and interest repayments, helping them to pay down their home loan in this low interest rate environment.” 

He also said there would be no switching fee for interest-only home loan customers to make the change to principal and interest repayments.

The changes are part of a growing trend that has taken hold since APRA announced regulations which limit the flow of new interest-only lending to 30% of a bank’s total new residential lending and also placed restrictions on the volume of low-deposit lending.

Earlier this month, CommBank subsidiary Bankwest and big bank ANZ both made similar adjustments to their home loan interest rates, increasing rates on interest-only borrowing, while making cuts on principal and interest loans.

Before that, in May, a number of lenders made moves that followed the same pattern of cuts for principal and interest borrowing combined with rate hikes for interest-only loans, including big bank NAB, which also quadrupled deposit requirements for interest only loans.
