March CPI Hits 4.6%: What Surging Inflation Means for the RBA's May 5 Rate Decision

Australia's Q1 2026 CPI data confirmed this week what many feared: annual inflation has risen to 4.6%, according to the ABS, dashing hopes of any near-term interest rate relief ahead of the Reserve Bank of Australia's critical May 5 board meeting.

What the Numbers Show

The ABS Consumer Price Index for March 2026 shows annual inflation at 4.6% — well above the RBA's 2–3% target band. This follows the RBA's last rate decision on March 18, 2026, which held the cash rate at 4.10%.

With the next decision now less than a week away on May 5, the persistently high inflation print significantly reduces the likelihood of a rate cut and raises the spectre of another hold or even an increase.

According to Australian Broker, the latest data "dashes hopes of a near-term interest rate pause," with market analysts reassessing expectations that had previously pointed toward a mid-2026 easing cycle.

Why This Matters for Mortgage Borrowers

For variable rate mortgage holders, a further hold — or rise — at the May 5 meeting means continued pressure on monthly repayments. Those already stretched at 4.10% may find their borrowing capacity shrinking as lenders apply higher serviceability buffers.

The MPFG Perspective: At MPFG Capital, we work with borrowers who often fall outside the rigid criteria of the major banks — self-employed individuals, new migrants, and those with non-traditional income streams. In high-rate environments like this one, the gap between what the banks will approve and what borrowers actually need tends to widen. Our Alt Doc and flexible lending solutions are specifically designed for this scenario.

What Happens on May 5?

Economists are divided. While the RBA has signalled a data-dependent approach, a 4.6% CPI print provides little room for optimism on rate cuts. The most likely outcome remains a hold at 4.10%, but the risk of a further increase cannot be ruled out if upcoming labour market data shows continued strength.

For borrowers with pre-approvals, now is the time to act. Pre-approvals typically expire after 90 days, and any rate movement — up or down — can affect assessed borrowing capacity.
