The cash rate is the interest rate set by the Reserve Bank of Australia for loans between banks in the overnight money market. It influences interest rates across the economy, including many home loan rates, savings interest rates and term deposit rates. For mortgage holders, a change in the cash rate may affect repayments, household budgets and the cost of borrowing, although lenders do not always change their rates by exactly the same amount.

The official cash rate is the Reserve Bank’s target for the rate banks pay when they borrow money overnight from other banks. These overnight loans help banks manage the cash they need for their day-to-day operations. The cash rate target is part of Australia’s monetary policy. The Reserve Bank uses monetary policy to influence inflation, employment, spending and economic activity. It is one of the main ways the RBA responds when inflation pressures, demand or economic growth move away from its goals.
The cash rate is sometimes confused with the interest rate on a home loan or savings account. They are connected, but they are not the same. The Reserve Bank sets the cash rate, while banks and other lenders set their own home loan and savings rates.
The Reserve Bank may raise or lower the cash rate to influence financial conditions in the economy. When inflation is too high, a higher cash rate may help reduce spending and demand. When economic activity is weak, a lower cash rate may support borrowing, business investment and household spending. The RBA considers a wide range of information before making an interest rate decision. This may include inflation, unemployment, wages, business conditions, household spending, the Australian dollar and developments in financial markets.
A cash rate increase is often described as a rate hike. A reduction is commonly called a rate cut. These decisions are intended to support price stability, full employment and Australia’s broader economic prosperity.
The RBA cash rate affects the cost of money in the banking system. When the cash rate rises, the interest banks pay for some types of funding may also increase. Lenders may then raise variable home loan rates to reflect higher funding costs and other business considerations. When the cash rate falls, lenders may reduce variable rates, but the change may be smaller or may not happen immediately. Each lender considers its own funding costs, competition, risk, market expectations and pricing approach.
This means a change in the official cash rate does not guarantee an identical change in a borrower’s home loan rate. Banks and other lenders may respond differently, even when the RBA makes the same decision for the whole economy.
A variable home loan rate may move during the life of the loan. If a lender changes the variable interest rate, repayments on a principal and interest loan may also change. The effect will depend on the loan balance, remaining term, repayment arrangements and the lender’s calculations. The size of any repayment change may vary between borrowers. A larger outstanding balance, longer remaining term or greater interest rate movement may result in a larger dollar change.
For example, a mortgage holder may receive notice that their interest rate is increasing after the Reserve Bank raises the cash rate. The lender may recalculate the minimum repayment using the new interest rate, outstanding balance, repayment arrangements and remaining loan term. This is why changes in interest rates may place pressure on a household budget. Some borrowers may find that comparing repayment estimates at several different interest rates can help illustrate how higher costs might affect a household budget, but this is general information only and does not consider their specific circumstances.
A fixed home loan usually keeps the same interest rate for an agreed period. An RBA interest rate decision does not generally change the contracted interest rate during an existing fixed-rate period, although the loan’s terms and conditions continue to apply. However, the cash rate may still affect fixed home loans in other ways. Lenders consider expected future cash rate movements, financial markets and their own funding costs when setting new fixed rates.
At the end of the fixed period, the loan may move to the lender’s applicable variable rate unless another arrangement is agreed with the lender. If the new rate is higher, repayments may increase. Some borrowers approaching the end of a fixed term may consider reviewing available rates, repayments, features and costs to understand how different options could affect their loan before the fixed period expires, noting that the most appropriate option will depend on their individual circumstances.
Higher interest rates may reduce the amount some applicants may borrow because lenders generally assess whether proposed repayments appear manageable under their lending criteria. As part of their assessment, lenders may test whether an applicant appears able to manage repayments at an assessment rate above the proposed loan rate. This assessment also considers income, regular spending, existing debts, dependants and other financial commitments. Two lenders may assess the same financial situation differently because their policies and calculations are not identical.
A lower advertised rate does not necessarily mean an applicant will qualify for a larger loan. Fees, loan features, income treatment and lender policy may also affect the assessment. Fees, loan features, income treatment and lender policy may also affect the result.
The cash rate is an important part of Australia’s financial system, but it is not the only factor that affects home loan interest rates. Lender funding costs, market conditions, loan type, borrower risk and product features may also influence the rate a borrower receives. Understanding how the cash rate works may help mortgage holders recognise possible repayment changes and feel more prepared to discuss general loan options with a lender or mortgage broker, but it does not replace advice that takes into account their objectives, financial situation or needs.

Not necessarily. Variable home loan repayments may change if the lender adjusts its rate, but the timing and size of the change may vary. Fixed home loan repayments generally remain unchanged during the fixed period.
Refinancing may help some borrowers access a different rate, loan structure or features, but it may also involve fees, application costs and changes to the loan term. Some borrowers may consider comparing the potential costs, features and longer-term effects before deciding whether to refinance. Refinancing may not provide a financial benefit in every case.
A mortgage broker may discuss how different lenders may assess an application and compare relevant options from their lender panel, including fixed or variable rates and available loan features. The options available will depend on the borrower’s circumstances and the lenders represented on the broker’s panel. Approval, pricing and borrowing amounts remain subject to each lender’s assessment, eligibility criteria and current policies.
