Understanding the RBA's Recent Rate Hike and Its Impact on Your Mortgage

Major banks, including Commonwealth Bank, NAB, and ANZ, have responded by passing on the full rate increase to their variable loan customers. For instance, ANZ has adjusted its Simplicity PLUS owner-occupier home loan rate from 5.89% to 6.15%, while CBA's Simple Home Loan rate has risen from 5.84% to 6.09%. These changes took effect on 13 February 2026, with Westpac following suit on 17 February 2026.

For borrowers making interest-only repayments—a structure often favoured by investors—the impact is immediate, as daily interest accrues at the higher rate from the date of the increase. Those paying principal and interest will receive notices from their banks outlining new minimum monthly repayments, with the higher interest rate applying to the outstanding balance from the effective date.

Calculations indicate that a borrower who recently purchased a median-priced house in a capital city could see their monthly repayments increase by up to $204 in Sydney, and between $125 and $150 in Adelaide, Perth, Melbourne, Canberra, and Brisbane.

In light of these developments, it's crucial for borrowers to assess their financial situations and explore options to manage increased repayments. Strategies may include refinancing to secure a more favourable rate, consolidating debts to simplify payments, or consulting financial advisors to develop a tailored plan.

Staying informed about interest rate trends and understanding their impact on personal finances is essential. Proactive management can help mitigate the effects of rate hikes and maintain financial stability.
