This feels like one of those moments where the finance “weather” changes faster than most households can update their spreadsheets.

The big headline: the cash-rate conversation has swung decisively from “maybe cuts later” to “rates higher and staying higher for longer”. At its early‑February meeting, the Reserve Bank of Australia (RBA) lifted the cash rate target by 25 basis points to 3.85%, arguing that inflation “picked up materially” in the second half of 2025 and that demand and capacity pressures look stronger than previously thought.

Alongside that, the inflation is still uncomfortably high for a central bank targeting 2–3% inflation. The Australian Bureau of Statistics (ABS) reported annual CPI inflation at 3.8% to December 2025, with trimmed-mean (underlying) inflation at 3.3%.

Westpac’s “house view” is that this isn’t just noise. Chief Economist Luci Ellis frames it as a genuine pivot in the rates outlook and the RBA has already moved, Westpac now expects another 25 bp increase in May.

At the same time, Westpac is drawing attention to a second, less obvious force that still matters for your borrowing costs; the Australian dollar has pushed and held above US$0.70, and markets commentary argues that this is being driven by both a more hawkish RBA and a broader US‑dollar sell‑off AKA dedollarisation.

Why does that matter for loans? Because inflation and interest rates are joined at the hip, and the currency move could end up doing more work in dampening inflation than policymakers may be assuming, just with a lag.

The core call: rates are higher, and why it is all about demand and capacity

It is not “rates are higher because someone changed their mind”. But “rates are higher because the economy surprised”.

Lets connect the dots.

The inflation is now higher and demand growth stronger than they previously expected; the RBA’s February hike is presented as the natural response, and Westpac’s baseline is that another hike comes in May.

This lines up with the RBA’s own language. The RBA said private demand “strengthened substantially more than expected”, driven by household spending and investment, while housing market activity and prices were “continuing to pick up”.

This combination results in firmer private demand, still-tight capacity, and inflation that has proven sticky. It matters for loans in two very direct ways:

• It raises the odds that the policy rate stays restrictive. Westpac explicitly expects inflation to remain slightly higher for longer and sees the RBA leaning into the upturn with further tightening.

• It changes the psychology of borrowing. When the central bank is worried that inflation will stay above target “for some time”, lenders don’t just set pricing off today’s cash rate many also start preparing for “higher for longer” in their funding, pricing, and risk assumptions.

An easy way to visualise this is to think of interest rates as the tide, even before the water reaches your feet, you can see it coming in. Westpac is saying the tide forecast has shifted up.

For a household, a 1% change in the path of rates is not an abstract economist’s unit. As a rough illustration: on a 30‑year loan, a 1 percentage‑point rise in the interest rate can add hundreds of dollars a month in repayments (the exact number depends on your current rate, loan size and term). This is why the shift is described in the rate outlook as a meaningful swing.

How today’s rates outlook becomes tomorrow’s mortgage and business loan pricing

A common frustration is: “The RBA moves 0.25%, but my bank doesn’t move exactly 0.25%.” Or, “Fixed rates changed even though the RBA didn’t.”

The reason is that most lending rates are built from two layers:

1. The policy anchor. The RBA cash rate influences other interest rates across the economy, including deposit and lending rates.

2. The bank’s funding and risk layer. The RBA explains that banks fund themselves mostly through deposits and market debt. Deposits are about two‑thirds of funding, while bonds and other debt securities are about one‑third (with equity and other sources making up the remainder).

So when the expected path of interest rates rises, at least three things tend to happen in the machinery behind your loan:

1. Banks’ wholesale funding benchmarks move quickly. The RBA notes that market reference rates are an important benchmark for pricing bonds and other debt, and it explicitly flags the bank bill swap rate (BBSW) as one of the key reference rates in Australia.

2. Deposit pricing doesn’t always move one‑for‑one. Banks have discretion in setting deposit rates, and deposit rates can adjust more slowly or by different amounts than the cash rate.

3. Competition and risk pricing can widen or narrow the “spread” over the cash rate. The RBA notes the spread between the cash rate and other rates varies over time because of competition and the riskiness of different loans.

As a result the rates outlook moved a lot not only because the RBA hiked in February, but also because markets and lenders are repricing the likelihood of what comes next.

This matters for:

• Variable-rate mortgages and business loans, which typically respond as bank funding costs and policy settings move.

• Fixed-rate loans, which tend to be influenced by longer-term bond yields and swap rates, so they can move on expectations, not just on actual RBA decisions.

It also matters for credit availability. Notably, the RBA itself said in early February that credit is “readily available” to households and businesses, and that the effects of earlier rate reductions are “yet to flow through fully” to demand and wages.

In other words, lending conditions in the RBA’s view, may not have been tight enough to get inflation back to target quickly; one reason policy has shifted.

The Aussie dollar above 70 cents is doing more than making overseas holidays feel cheaper

The exchange rate is not just a side-effect of higher Australian rates, it may be an extra channel that changes the inflation outlook meaningfully.

As of now the Australian dollar hit 0.7147 and, despite choppy trading, is being “well supported above 0.7” by a hawkish RBA, broad “antipathy” towards the US dollar, and robust commodity prices.

As a companion piece, the US‑dollar sell‑off has pushed the Australian dollar higher than the shift in domestic rates alone would imply.

Westpac’s mechanism is essentially a three step chain:

1. Global investors are pivoting away from USD exposure, sometimes by selling USD assets, and sometimes by keeping US assets but hedging the currency risk which still involves selling USD forward and buying other currencies.

2. Australia can feel the effect more intensely because it’s a smaller market, which has helped compress credit spreads outside the US and made non‑US credit markets (including Australia) unusually vibrant.

3. A higher Australian dollar tends to lower imported inflation over time (imports become cheaper in AUD terms), but the key is that this episode may dampen imported inflation by more than you would infer from interest-rate changes alone, because the currency move is being driven by global portfolio shifts and hedging behaviour not just the usual domestic-cycle dynamics.

Why should a borrower care about imported inflation?

Because inflation is what determines whether a “May hike” is the end of the story or just the start. If imported goods inflation is set to cool later in the year and into next, that can reduce the need for rates to go even higher, though the impact takes time to show up in CPI. The higher AUD should put downward pressure on inflation in imported items over the next year or two, and that the RBA may not have fully incorporated this risk into its February assessment.

This is also a “timing” story. The RBA itself emphasises that monetary policy affects the economy with long and variable lags; its explainer suggests the maximum effect can take one to two years, and that there’s uncertainty around the exact timing.

So Westpac can simultaneously argue “rates need to rise again soon” and “the currency will matter later”. Those two ideas don’t conflict, they run on different clocks.

A vibrant credit market can soften the blow, but it doesn’t cancel the cash-rate reality

If you only watch the RBA cash rate, you might miss a second moving part in the cost of finance; the credit spreads.

This global pivot out of USD exposure has shown up less in big moves in major-government bond yields, and more in compressed credit spreads and stronger issuance activity in smaller debt markets like Australia.

That has two important implications for financing and loans:

1. It can reduce the “extra margin” some borrowers pay above the relevant benchmark. A business loan priced at “BBSW + margin” becomes more affordable if competition and investor appetite compress the margin, even if BBSW itself is higher. The RBA’s framework agrees this is how lending rates behave: banks set lending rates with an eye to funding costs, competition, and credit risk, and those factors can shift the spread over time.

2. It can keep credit flowing for longer than you’d expect. The RBA explicitly noted in February that credit remains readily available and that the effects of earlier rate reductions are still flowing through.

A vibrant debt markets is a plausible way the system can stay “less restrictive” at a given cash rate than older playbooks would assume.

But this is not a free lunch. Easier credit conditions can also sustain demand and, if demand stays too strong, it keeps inflation sticky and invites more tightening.

That’s why Australian regulators have a “belt and braces” approach. Separate to monetary policy, Australian Prudential Regulation Authority (APRA) has been actively trying to stop riskier mortgage lending from snowballing. In late 2025 it announced a new “speed limit” on high debt‑to‑income home lending: from 1 February 2026, banks can lend no more than 20% of new mortgages to borrowers with debt of six times income or more (applied separately to owner‑occupiers and investors).

APRA also reaffirmed that the mortgage serviceability buffer remains 3 percentage points.

In practice, this means that even if markets are enthusiastic and credit spreads are tight, borrowers at the higher‑risk end may find the guardrails get in the way. That’s particularly relevant in a world where Westpac and the RBA are both telling you rates are moving up, not down.

What this means for everyday borrowers, in plain terms

Hint, it is not “panic”. It’s “update your mental model”. The model is: rates are likely to rise again, but the currency may help on inflation later, and **financing conditions are being shaped by global capital flows as much as local policy.

Here’s how that tends to land, depending on the kind of loan you have (or want).

For variable-rate mortgage holders, the big issue is cash-flow sensitivity. The RBA’s own explainer highlights the cash‑flow channel: higher rates reduce the cash households have available to spend, especially for those already close to their borrowing limit.

If Westpac’s baseline of another move in May is right, the immediate household impact is usually straightforward: repayments rise quickly after lenders pass through higher funding costs and policy settings.

For borrowers deciding between fixed and variable, the key is to understand that “fixed” is priced off expectations (and banks’ funding costs), not just today’s RBA decision. If markets have already priced a higher track for rates, fixed rates can look expensive before the RBA actually delivers. That’s a feature, not a bug, of the way lending rates are built.

For small businesses and commercial borrowers, a vibrant credit market is the potential pressure valve. Strong investor appetite and tighter credit spreads can mean more active markets for bank bonds, securitisation, and corporate issuance; conditions that can support lending competition.

But the RBA’s February message: credit is readily available, demand is strong, capacity pressures are evident also signals why lenders may remain selective on risk, even if the volume of credit is healthy.

For borrowers exposed to the construction and “public footprint” parts of the economy, the structural story matters. It can be argued that public spending now generates a record 35% of domestic output and is linked to nearly 40% of total employment, creating capacity pressures in some industries and contributing to higher inflation in those sectors at times.

An accessible summary of this argument in the Australian context is captured in an ABC analysis piece that quotes those same figures and links them to today’s inflation pressures, link here: Rise of Australia’s public economy is comparable to the mining boom of the 2000s

For financing, this matters because capacity constraints (for labour, materials, and specialist services) can keep costs and prices elevated longer; exactly the kind of environment where lenders stay cautious and the central bank stays hawkish.

Finally, the strongest “watch this space” is the exchange rate channel. If the Australian dollar’s appreciation proves persistent, Westpac thinks it could dampen imported inflation by more than expected, potentially changing the inflation path over the next year or two an argument that, if it plays out, would be relevant to how high rates ultimately need to go.

The core takeaway for borrowers is:

The loan environment is being re‑priced around stronger demand, sticky inflation, and a higher peak in rates than seemed likely only months earlier, with the Australian dollar and global credit conditions acting as important second‑round influences rather than mere background noise.
