RBA March 17 Decision: What Every Borrower Needs to Know

The Reserve Bank of Australia meets on Tuesday 17 March 2026 — and this time, nobody is taking a hold for granted. After raising the cash rate to 3.85% in February — the first hike in more than two years — Governor Michele Bullock has refused to rule out a follow-up move, telling reporters that "every meeting is live." All four major banks currently forecast at least one more hike, most pointing to May. But with the March meeting just days away, here's what you need to understand before Tuesday's announcement.

Where Things Stand Right Now

February's 0.25% hike ended the shortest rate-cutting cycle in the RBA's modern history. The three cuts of 2025 — which briefly pushed some fixed rates below 5% — have now been fully offset by the February increase and the market's repricing in anticipation of more. Sub-5% home loan rates have disappeared from the market as of March 2026.

What a Second Hike Would Actually Cost You

If the RBA raises rates again — whether in March or May — the impact hits every variable rate borrower immediately. Fixed rate borrowers are shielded until their term expires, at which point they roll onto the prevailing variable rate.

A second hike also shrinks what buyers can borrow. Canstar research shows each 0.25% rise strips roughly $12,000 from the average income earner's maximum borrowing capacity. Two hikes since the start of 2026 would reduce that capacity by approximately $24,000 — a meaningful constraint for buyers already stretched by Sydney and Melbourne prices.

Why the RBA Might Hike Again in March

The case for another hike rests on two things: inflation is still too high, and the labour market is still too tight.

Headline CPI remains above the RBA's 2–3% target band and is forecast to stay there until 2027. Services inflation — the stickiest component, driven by wages — remains elevated. Governor Bullock has been explicit: the Board will not accept inflation drifting above the target band indefinitely, and the February hike alone may not be enough to bring it back in line within the timeline the RBA has set.

Why the RBA Might Hold in March

The case for a hold is also real. Monetary policy works with a lag — the February hike is only now beginning to flow through to household budgets. Hiking again before the February increase has had time to work risks overtightening: pushing the economy into a sharper slowdown than intended.

Consumer sentiment has already deteriorated. Retail spending is weakening. And global uncertainty — including the escalating Middle East conflict and ongoing US tariff pressures — has introduced genuine downside risk to global growth. The RBA has historically preferred to pause and observe before acting again in rapid succession.

The market consensus as of early March leans toward a hold in March, with a hike more likely in May. But "likely hold" and "guaranteed hold" are very different things, and Bullock's explicit refusal to rule out March action means borrowers should not count on it.

What the Big Four Banks Are Forecasting

Should You Fix Your Rate Before 17 March?

This is the question we're getting most frequently right now. The honest answer has several parts:

Fixed rates have already moved. Lenders don't wait for the RBA to act — they price future hikes into fixed rates ahead of time. The fixed rates available today already reflect market expectations of one more hike. That doesn't mean fixing is wrong, but it means you're not "getting ahead" of a hike that hasn't happened — you're paying for it regardless.

What fixing gives you is certainty, not a lower rate. If your budget is tight and a further $90-$300/month increase would genuinely stress your finances, locking in a fixed rate gives you a known payment for 1–3 years regardless of what the RBA does. That certainty has real value — just understand you're paying for it.

A split loan may be the best of both worlds. Fixing 50–70% of your loan protects the majority of your repayments from further increases, while leaving the remainder variable so you can keep making extra repayments and using your offset account. This is the approach many of our clients are currently taking.

The 1-year fixed rate is worth watching. If the peak rate is 4.10% in May and the RBA then holds, cuts could start by late 2026 or early 2027. A 1-year fixed rate would likely roll off just as variable rates are falling — potentially giving you the best of both phases. A 2 or 3-year fix locks you in through the cutting cycle and may cost you in break fees if you want to exit early.

What to Do Before 17 March

• Check your current rate. If you haven't renegotiated in the past 12 months, you are almost certainly paying more than you need to. The gap between loyalty rates and competitive rates from other lenders can be 0.5–1.0% — that's $3,000–$6,000 per year on a $600,000 loan.
• Run your budget at 4.10%. Model what your repayments look like if the cash rate hits the big-four forecast of 4.10%. If that number causes real stress, start exploring options now rather than after the hike lands.
• Don't rush into fixing without comparing. Fixed rates vary significantly between lenders right now — we're seeing spreads of 0.4–0.6% between the best and worst 2-year fixed rates in the market. A broker can benchmark your options across 30+ lenders in one conversation.
• Check your offset balance. If you have a meaningful sum in your offset account, make sure it's working as hard as possible against your loan balance before any rate increase hits.

The Bottom Line

The market consensus is a hold on 17 March, with May the more likely date for the next hike. But the RBA has surprised markets before, and Bullock's tone since February has been unambiguously hawkish. Whether the hike comes in March or May, the direction of travel is clear: rates are higher for longer than anyone expected six months ago, and borrowers who plan for that reality will be in a better position than those who hope the RBA will change its mind.

The March 17 announcement is at 2:30pm AEDT. We'll be watching closely.
