How to read this page

The four tiles at the top show the live policy rate (set by the central bank), the interbank rate, and the typical fixed and variable mortgage rates available to a household in this country. 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 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.

Como a política do RBA chega às taxas hipotecárias australianas

O Reserve Bank of Australia define a Cash Rate Target — a taxa overnight pela qual os bancos emprestam saldos de liquidação entre si. A Cash Rate ancora a Bank Bill Swap Rate (BBSW), o principal benchmark de financiamento de curto prazo usado para precificar hipotecas variáveis.

A Austrália tem o mercado hipotecário mais dominado por taxas variáveis do mundo desenvolvido. Aproximadamente 80% das hipotecas em aberto estão em taxa variável, quase todas atreladas à taxa variável padrão (standard variable rate, SVR) do credor ou a um desconto sobre a SVR. O resultado: um movimento na cash rate do RBA se transmite à taxa hipotecária média em aberto em um a dois meses, a transmissão mais rápida entre as grandes economias depois do Reino Unido.

Produtos de taxa fixa existem, mas perderam popularidade após o episódio de 2020-2022, no qual a maioria das hipotecas fixas travou taxas de 2-3% pouco antes do ciclo de altas de 425 pontos-base do RBA, levando a um estresse generalizado do chamado “penhasco da taxa fixa” (fixed rate cliff) à medida que essas fixações venciam em 2023-2024.

Retrato atual das taxas

A tabela mostra a taxa variável padrão, a taxa fixa de 3 anos, a BBSW de 3 meses e a Cash Rate. Em maio de 2026, a taxa variável padrão típica para mutuários ocupantes está na faixa dos 6% baixos, com as fixas de 3 anos precificadas ligeiramente abaixo.

Spread histórico frente à Cash Rate

O spread entre a taxa variável padrão e a cash rate tem se mantido notavelmente estável em 2,0 a 2,3 pontos percentuais desde o período pós-2010, com dois alargamentos notáveis:

A taxa fixa de 3 anos é mais variável; ela acompanha a BBSW mais um prêmio de prazo e pode ficar acima ou abaixo da taxa variável, dependendo das expectativas de mercado.

Trajetória projetada para 12 meses

A trajetória implícita é construída a partir dos futuros de Cash Rate Interbancária de 30 dias da ASX (código de produto IB da ASX), o contrato mais líquido para as expectativas de juros de curto prazo na Austrália. A taxa hipotecária projetada aplica um repasse (pass-through) alto (0,95) e uma defasagem muito curta (1 mês), refletindo a estrutura da Austrália, dominada por taxas variáveis.

Se a trajetória implícita pelos futuros aponta para novos cortes do RBA, a taxa variável padrão deve cair em compasso próximo, com a maioria dos credores repassando os cortes da cash rate dentro de um único ciclo de faturamento.

Particularidades dos produtos hipotecários na Austrália

Os quatro grandes bancos (CBA, Westpac, NAB, ANZ) detêm coletivamente ~75% das hipotecas em aberto.
