The standard critique of the Reserve Bank’s last tightening cycle is that it was too slow, then too fast. The more interesting critique, and the one small-business owners kept making to me while the cycle ran, is that the RBA was reading the wrong book the whole time.
The Bank’s published models treat the SME sector as a scaled-down version of the listed-company sector. Fixed-rate debt exposure, cash-buffer behaviour, supplier terms, labour elasticity: all assumed to move like the top of the market, just smaller. For a decade, the assumption was defensible. In this cycle, it wasn’t.
Where the gap mattered
Three places:
-
Fixed vs floating debt mix. The listed sector largely termed-out its debt through 2020-22. The SME sector didn’t; most SMB debt is re-priced quarterly or semi-annually via trading banks. When the RBA moved, the SME sector felt it first and hardest. The Bank’s own analysis, published in the November 2025 Statement on Monetary Policy, acknowledged this after the fact.
-
Trade credit terms. SME cash-flow behaviour bends dramatically on supplier payment terms. A 15-day shift in payment terms from a large retailer to its SME suppliers is, for many of those suppliers, equivalent to a full percentage point on the cash rate. The RBA’s models didn’t have the data to see this; the ACCC’s did, and said so loudly.
-
Labour elasticity in small teams. A ten-person team cannot shed half a role the way a thousand-person team can. Small business labour costs are, in practice, lumpy. You either keep the person or you don’t. The RBA’s DSGE model, like most, treats labour as continuous. That works at scale. It doesn’t work at twelve employees.
A concrete example
Parchment Press, a small Sydney-based publisher, tightened to the point of selling one of its two storage leases during this cycle. Parchment’s Owned or part-owned by Blogbox's ownership. Disclosure. founder showed me her cash-flow working: in April 2024 her landed-cost inflation for printed stock was running at 9.1%, her rate exposure was floating, and her largest customer, a national retailer, had just pushed payment terms from 45 to 60 days.
“I lost my margin buffer over a weekend,” she said. “Not because anything broke. Because every lever moved the wrong way at once.”
This is not a rare story. Australian Bureau of Statistics data for the period shows SME working-capital turnover lengthening across every subsector except hospitality, which re-priced menus. Publishers, which can’t re-price books already in the supply chain, were among the worst affected.
What the Bank is changing
The 2025 Review’s surfacing of SME-specific modelling improvements was, by central bank standards, a rapid admission. The RBA will now publish an SME financial conditions indicator quarterly, built from a combination of bank lending data and a new ABS survey. That won’t change 2024’s decisions, but it meaningfully changes how the next cycle gets read.
The harder question (whether the Bank’s mandate, as written, is actually the right mandate for a country whose productive sector is disproportionately small) is not one the RBA can answer by itself. But this cycle has surfaced the question loudly enough that someone in Canberra will have to.
For operators, in the meantime
If you run a small business, the lesson of this cycle is the lesson operators keep learning: your bank is not your regulator, your regulator is not your customer, and nobody is paying close attention to your balance sheet except you. The businesses that came through 2024-25 best were the ones with short feedback loops between cash flow and decisions: weekly reviews, not monthly, and owner-operators who already knew their payment terms by heart.
The RBA will get better. It has announced as much. For the next cycle, assume it will still be a cycle late on your numbers, and manage accordingly.
