Four Hikes In: Rate Stress Reaches the Loan Book Long Before It Reaches Arrears

Ares Management has warned that rising rates could intensify the pressure on Australia’s A$200 billion private credit market, particularly for lenders exposed to property. The warning lands at a moment when most loan books still look healthy on paper, which is exactly when rate stress is most dangerous.

The warning came from inside the asset class

Peter Graf, partner and head of Asia direct lending at Ares, delivered the message at the Citi Australia & New Zealand Investment Conference in Sydney in October. According to Private Equity Wire, which reported the remarks citing Bloomberg, Graf said higher borrowing costs were increasing the risks for real estate borrowers and that lenders need to scrutinise underlying asset quality and borrowers’ financial positions. The Reserve Bank has raised the cash rate four times this year, taking it to 4.6%.

The detail that matters most is the repricing. Graf reportedly said senior real estate loans that priced at 8 to 9% six months ago could now command yields of 11 to 12%. That is good news for new money and a quiet problem for old money. Every loan written at the old price was underwritten against a cost of capital and a borrower cash flow that no longer exist.

Graf did not predict a systemic squeeze, and neither did the Reserve Bank. The market will not break all at once. Individual books will crack one borrower at a time, and the managers who see the cracks first will have the most options.

A 100 basis point move is not a rounding error for a developer

The RBA’s Financial Stability Review confirms the Monetary Policy Board has lifted the cash rate by 100 basis points to bring inflation back to target. For a salaried borrower with a mortgage buffer, that is painful. For a residential developer funded on a floating-rate construction facility, with no income until settlement and costs already inflated by persistent construction inflation, it can be the difference between a project that completes and one that stalls.

The RBA’s own liaison picks this up. For the segment of business lending provided by private credit funds, the bank says “there has been some tightening of financial conditions and an increased sensitivity to project risk,” and warns this may affect access to funding for businesses that usually rely on these lenders, “including some residential property developers.” It also notes that company insolvencies remain elevated in hospitality, construction and transport.

Think of a construction loan as a bucket with a slow leak. Capitalised interest drips out every month, and the only thing that refills the bucket is the sale of the finished asset. Raise the rate and the leak gets faster. Weaken residential prices, which the RBA and Ares both describe, and the refill gets smaller. Nothing about this shows up in arrears, because capitalised interest is never late. The loan is current right up until the day the numbers stop working.

Arrears is the receipt, not the warning

This is the trap. Most private credit books are monitored on payment status, and payment status is the last thing to move. Interest that is capitalised cannot fall into arrears. A borrower drawing on an interest reserve looks perfect until the reserve runs dry. A sponsor with five projects can keep every loan current by moving cash between them, until the day it cannot.

Bathla Group showed what that looks like at scale. The Sydney developer entered insolvency in August owing approximately A$3.4 billion, primarily to private debt funds, according to Private Equity Wire. The RBA’s private credit box notes that real estate concentrated funds are “more exposed to stress in the property sector, as demonstrated by the large number of funds with exposures to the recent insolvency of a larger property developer.”

The useful signals in a rising rate environment are forward-looking ones. Interest coverage at today’s rate rather than the rate at settlement. Months of interest reserve remaining. Loan to value ratio against a current valuation rather than the one in the credit paper. Cost to complete against budget. Concentration to a single sponsor across every facility and every fund. None of these are exotic. All of them are hard to calculate quickly when the data lives in a spreadsheet, a PDF valuation and someone’s inbox.

Repricing the book is a stress test you are already running

Ares’ 11 to 12% figure has a second edge. If new senior real estate loans now price at those levels, the market is telling you what it thinks the risk is worth today. Your existing book, written at 8 to 9%, is carrying that same risk at the old price. That gap is not a mark to market in the accounting sense, but it is a signal about where credit quality has moved since origination.

Blackstone’s Mark Glengarry, head of APAC Private Credit Strategies for Blackstone Credit and Insurance, said some projects may have received financing that would not have been available under stricter conditions, and that he expects the market to work through those exposures. Cbus Super’s Anne Moal, head of direct debt and illiquid credit, said the fund had held its underwriting standards but was finding fewer attractive construction financing opportunities. Read together, that is the sound of an asset class repricing its own history.

The RBA has already run the scenario most managers have not. Its very adverse case takes the cash rate to 5.6%, unemployment to 6.3% and inflation to 7%. Any manager can ask the same question of their own book: if the cash rate moves another 100 basis points, which loans fall below an interest coverage ratio of one, which interest reserves run out before practical completion, and which sponsors appear in more than one of those lists?

The managers who can answer that in an afternoon get to act. They can restructure early, call for equity, tighten drawdown conditions or simply stop lending to the sponsor before the next facility is signed. The managers who need three weeks to assemble the answer find out from the administrator.

Rate risk is an architecture problem

Most private credit operating models were built for flat or falling rates: data captured once at origination, servicing run on payment status, reporting assembled quarterly. That model breaks when the cash rate moves four times in a year, because every loan’s risk profile changes at once and nobody can recompute the book fast enough.

Negroni was built for the opposite assumption. Negroni Automation turns loan documents, valuations and borrower financials into structured data at intake, so the inputs a stress test needs already exist rather than being rekeyed from PDFs. Negroni Management monitors covenants, interest reserves and servicing events continuously against an immutable audit trail, so a reserve running low is flagged on a schedule rather than discovered at a drawdown. Negroni Analysis models rate shifts, defaults and concentration risk against the whole book in minutes, not weeks, at position-level granularity. The software does the arithmetic. The credit team keeps the judgement about what to do with the answer, which is where it belongs.

The window is now, not at the next quarter end

Ares, Blackstone and the RBA all point the same direction. The market is not about to collapse, but stress is building in property-linked books, it is building first in loans that look current, and it will be uneven. The lenders who come through this cycle well will not be the ones with the best forecasts for the cash rate. They will be the ones who can see what any given cash rate does to their book, loan by loan, before their investors or their regulator ask. That is the same discipline behind the six questions every manager faced after Bathla.

Run the test now, while the answer is still a choice rather than a consequence.

Frequently asked questions

What did Ares warn about Australian private credit? Ares Management warned in October 2026 that rising interest rates could intensify stress in Australia’s A$200 billion private credit market, particularly for lenders exposed to property. Peter Graf, Ares’ head of Asia direct lending, said higher borrowing costs were increasing risks for real estate borrowers and urged lenders to scrutinise asset quality and borrower finances. He did not predict a systemic credit squeeze.

Why do rising rates hurt private credit property loans more than other lending? Private credit property loans in Australia are often floating-rate construction and development facilities where the borrower has no income until the project sells. Rising rates increase capitalised interest and erode the margin between project costs and sale proceeds. When residential prices also weaken, the project can become unviable while the loan still appears current.

Why is arrears a poor early warning signal for private credit loan books? Arrears measures missed payments, and many private credit loans capitalise interest or draw on interest reserves, so they cannot fall into arrears until the structure runs out. By the time a construction loan shows arrears, the borrower’s position has usually deteriorated for months. Forward-looking measures such as interest coverage at current rates, reserve runway and current loan to value ratio show stress earlier.

How should a private credit manager stress test a loan book for rate rises? A private credit rate stress test should reprice every floating-rate loan at a higher cash rate and identify which loans fall below an interest coverage ratio of one, which interest reserves will exhaust before completion, and which sponsors appear across multiple stressed loans. The RBA’s own very adverse scenario uses a 5.6% cash rate, which is a reasonable benchmark. The test is only useful if it can be run in hours, so it can be repeated as rates move.

Is Australian private credit a systemic risk according to the RBA? The Reserve Bank of Australia’s October 2026 Financial Stability Review says private credit funds do not pose a system-wide financial stability risk at present. The RBA estimates private credit at around 10% of business debt and less than 2% of financial system assets, with limited bank linkages. It does note that real estate concentrated funds are more exposed to property sector stress.
