How RBA Rate Moves Flow Through to Your Mortgage Repayments

How RBA Rate Decisions Flow to Your Mortgage

The Reserve Bank of Australia sets the cash rate, which influences the variable interest rates that lenders offer on home loans. When the cash rate changes, your monthly repayment can change correspondingly, depending on your loan amount and the rate adjustment.

Understanding the Transmission Mechanism

A change in the cash rate affects the cost of funds for lenders, and they typically pass changes on to variable-rate borrowers. The exact timing and extent of pass-through may vary, but a direct link exists between the cash rate and the interest rate on your mortgage.

Worked Examples: Loan Amounts and Monthly Payments

To illustrate, consider how a 0.25 percentage point change in the cash rate can affect monthly repayments on different loan amounts. The following examples assume a 30-year loan term with principal and interest repayments.

Note: These figures are illustrative only and assume the full rate change is passed through. Actual repayments depend on your specific rate, fees, and loan terms.

Factors That Affect Your Repayment

Your monthly repayment also depends on the loan term, whether you are on a fixed or variable rate, and any fees or charges. A longer loan term reduces monthly repayments but increases total interest paid. Fixed-rate loans are not immediately affected by cash rate changes until the fixed period ends.

What Borrowers Can Do

If you have a variable-rate mortgage, it’s worth reviewing how any rate change affects your budget. You can estimate the impact using your loan balance and interest rate. If you’re considering a new loan or refinancing, compare offers to ensure you’re getting a competitive rate.
