Australian mortgage holders pumped record sums into offset and redraw facilities in August, bank data show, as households tried to park cash ahead of a Reserve Bank decision that markets expect will lift the cash rate to 4.60 per cent on Tuesday.

Redraw inflows hit a two-year high at the majors in August

Commonwealth Bank, Westpac and NAB all reported stronger net inflows into mortgage-linked savings buckets in their September trading updates, even as new lending slowed. Nathan Price’s desk said the pattern reflects borrowers who still have equity buffers trying to reduce interest-bearing principal without breaking fixed-rate contracts that remain cheaper than today’s variable offers.

Why redraw matters now

Unlike an extra repayment that disappears unless you apply to get it back, a redraw facility lets customers pull surplus payments when needed. That flexibility has become attractive for households nervous about unemployment edging up to 4.6 per cent while grocery and insurance bills stay elevated. Finder’s consumer research team said one in four variable-rate borrowers surveyed in September planned to build redraw before any rate announcement.

Offset accounts operate similarly for many packages, sweeping salary deposits against loan balances daily. ANZ economists noted that offset balances often rise when consumers expect rates to peak, then fall when confidence returns. The current spike suggests many families still think at least one more hike is coming after Tuesday, with ANZ and Citi among banks forecasting a follow-up move in November.

Credit card spillovers

The same households are not running up card debt at the same pace. RBA credit aggregates for August showed personal credit growth slowing, while mortgage buffers grow. That divergence matters for card issuers who rely on revolvers for margin, but it also reduces systemic risk if unemployment rises faster than the board expects.

Consumers comparing products should watch comparison-rate disclosures on packaged home loans, where offset and redraw features are bundled with annual package fees near $400 at some majors. ASIC’s September warnings on lead-generation websites apply here too: a “best offset” table that funnels clicks to a single lender may not be comparing the full market.

What changes after Tuesday

If the board delivers the priced 25-basis-point increase, variable customers will see repayments rise within days, while redraw balances will offset a smaller share of principal than before. Fixed-rate borrowers rolling off 2023 peaks near 2 per cent face a sharper cliff, which is why redraw inflows are concentrated among variable customers who still have time to build cushions.

Banks stress-tested these buffers in their half-year results, assuming unemployment near 4.75 per cent. Monday’s redraw data suggest households are doing their own stress tests in real time. For the RBA, the message is mixed: balance sheets look resilient, but the rush to hoard cash is hardly a sign of consumer confidence.
