How to read this page
The four tiles at the top show the live policy rate (set by Reserve Bank of Australia), the interbank rate (BBSW 3M), and the typical fixed and variable mortgage rates available to a household in Australia. The gap between the policy rate and the mortgage rate is the spread — what the lender adds on top to cover funding, credit risk and profit.
The first chart shows that spread over the last five years. When the shaded area widens, banks are charging more on top of the policy rate, usually because the long bond market has moved or because banks are pricing in extra risk. When it narrows, competition or central bank bond-buying is squeezing margins. The second chart — the implied 12-month forward path — takes the current futures market's bet on where the policy rate is heading, applies the historical spread, and shows where your mortgage rate would land if both relationships hold. It is not a forecast: it is what current market pricing already implies.
Country-specific spread drivers
The mortgage-minus-policy spread observed for Australia (2.14pp current vs 2.00pp historical mean) decomposes into four primary drivers. First, the funding curve: jurisdictions whose lenders fund predominantly via covered bonds (Germany, Denmark, France, Sweden) inherit the swap-plus-covered-spread basis, which moved from 5-15 bp pre-2022 to 25-50 bp during the ECB's APP/PEPP unwind. Lenders funded via deposit franchise (UK, Australia) anchor more to short-rate transmission and deposit beta. US lenders sell loans into agency MBS pools, so the spread is sensitive to the primary-secondary MBS basis and to Fed SOMA reinvestment policy.
Second, prepayment optionality and convexity: products without economic prepayment penalty (US 30Y, Danish callable bonds) trade at OAS rather than nominal spread; OAS widening during rate volatility regimes (VIX-Treasury MOVE comovement) bleeds straight into the borrower rate. Penalty-protected European products (German Festzins under §489 BGB, French indemnité de remboursement anticipé) carry minimal optionality premium. Third, lender duration mismatch: if the dominant local product is short-fixed (UK 2/5Y) the lender's asset-liability gap is small and the spread is stable; if long-fixed (US 30Y, German 10Y) lenders rely on swap and MBS markets to hedge duration, and spread widens when those hedge markets stress. Fourth, regulatory caps and capital treatment: France's taux d'usure, prudential LTV/DTI floors (Switzerland, Australia, Canada), and Basel III risk-weight differentiation across LTV buckets all alter the marginal cost of lending and feed back into quoted rates with lags of one to three quarters.

How RBA policy reaches Australian mortgage rates
The Reserve Bank of Australia sets the Cash Rate Target — the overnight rate at which banks lend exchange settlement balances to each other. The Cash Rate anchors the Bank Bill Swap Rate (BBSW), the dominant short-term funding benchmark used to price variable mortgages.
Australia has the most variable-rate-heavy mortgage market in the developed world. Roughly 80% of outstanding mortgages are on variable rates, almost all linked to the lender’s standard variable rate (SVR) or to a discount off SVR. The result: an RBA cash rate move passes through to the average outstanding mortgage rate within one to two months, the fastest pass-through of any major economy after the UK.
Fixed-rate products exist but lost popularity after the 2020-2022 episode in which most fixed mortgages locked in rates of 2-3% just before the RBA’s 425 bp hiking cycle, leading to widespread “fixed rate cliff” stress as those fixes rolled off in 2023-2024.
Current rate snapshot
The snapshot table shows the standard variable rate, 3-year fixed rate, BBSW 3-month, and Cash Rate. As of May 2026 the typical owner-occupier standard variable sits in the low-6% range, with 3-year fixes priced slightly below.
Historical spread vs. Cash Rate
The spread between standard variable and the cash rate has been remarkably stable at 2.0-2.3 percentage points since the post-2010 era, with two notable widenings:
- 2008-2009 GFC: spread widened by ~50 bp as wholesale funding stress forced banks to repass beyond pure cash rate moves.
- 2020 COVID: spread compressed to ~1.8 pp during the RBA’s Term Funding Facility (TFF) which gave banks 0.10% three-year funding.
- 2023-2024: spread normalised back to ~2.1 pp.
The 3-year fixed rate is more variable; it tracks BBSW + a term premium and can sit either above or below the variable rate depending on market expectations.
12-month forward path
The implied path is built from ASX 30-day Interbank Cash Rate Futures (ASX product code IB), the most liquid contract for Australian short-rate expectations. The projected mortgage rate applies a high pass-through (0.95) and very short lag (1 month) reflecting Australia’s variable-rate-dominant structure.
If the futures-implied path is for further RBA easing, the standard variable rate should fall in close lockstep, with most lenders passing on cash rate cuts within a single billing cycle.
Australia-specific mortgage product norms
- Standard Variable Rate (owner-occupier, principal & interest): the modal product, typically 5.5-6.5% in 2026.
- Investor variable loans price ~25-40 bp above owner-occupier (regulatory pricing).
- Interest-only investor loans price ~25-50 bp above principal & interest.
- 2/3/5-year fixed rates exist but only ~20% of new business is fixed.
- Offset accounts are nearly universal: deposits in an offset account reduce the interest-bearing balance dollar-for-dollar.
- Lenders Mortgage Insurance (LMI) kicks in below 80% LTV.
The four major banks (CBA, Westpac, NAB, ANZ) collectively hold ~75% of outstanding mortgages.
