Arch Insurance Australia (Arch) has doubled the property capacity it will deploy on a single location, taking its limit on lower hazard occupancies to $100 million. Brendon Terry (pictured), northern region branch manager and head of property at Arch Insurance in Australia, confirmed the increase in a recent interview with Insurance Business.
"So much so that I can announce we're once again increasing our capacity to provide up to 100 million per location on our lower hazard occupancies," he said.
The move could be less about capacity than about timing. Australian commercial property rates have been falling for well over a year and the conventional response to a softening cycle is to hold discipline and wait it out. Arch is doing the opposite - using the soft phase to buy structural share, on the bet that limit, not price, is what brokers remember when the market turns.
"We've moved that from 50 million and that's only just come to the forefront in the last few weeks – so that's pretty fresh."
The conditions it lands in are unusually competitive. Marsh's Global Insurance Market Index for the first quarter of 2026 recorded a 12% fall in Pacific commercial rates, with property down 14% - the steepest regional decline globally. EBM Insurance & Risk's Insurance Market Trends and Outlook, released in May 2026, described broad insurer appetite and expanded capacity across the Australian market.
When capacity is abundant, more capacity is not automatically a differentiator. Terry's argument is that the size of the line is.
"So it lifts us out of where a lot of agencies might play and allows us to start challenging some of our larger competitors," he said.
For brokers, the practical effect is arithmetic. A carrier willing to write up to $100 million on a single location reduces the number of participants needed to complete a layer, which shortens placement time, cuts co-insurance administration and removes a point of failure at renewal - particularly on accounts where one reluctant follower can stall the whole programme.
It also changes the leverage position. During the sudden softening of commercial property insurance across the Australian market, the constraint on testing incumbent pricing has often been finding a credible alternative willing to take a meaningful line rather than a token participation. A doubled limit makes that alternative viable on larger mid-market risks.
The constraint is the occupancy, not the location. The $100 million applies to lower hazard classes only and brokers should not read the figure as blanket appetite across the property spectrum.
Arch's willingness to put that much behind one address rests on what it has spent several years removing from the book.
Hospitality - the foundation on which the Australian property portfolio was built - now accounts for less than 30% of it. Retail, wholesale, light engineering, aged care and healthcare have absorbed the balance. Aged care and healthcare property in particular has been difficult to place through the hard market and Arch's presence there is arguably more immediately useful to a broker than the headline limit.
The portfolio is built around occupancy rather than location, with a deliberate decision to stay out of catastrophe-heavy programmes. That discipline is what makes a $100 million line defensible: the aggregation risk that would normally make an insurer nervous about concentrating limit has been managed out at the appetite level rather than at the underwriting desk. It is also a reasonable hedge in a market where weather-exposed property continues to attract tighter terms even as clean risks see reductions.
Property is not the only line moving. Arch has separately lifted casualty capacity to $50 million and launched a management liability product through the Sunrise Exchange platform aimed at regional broking firms, while flagging Queensland as a growth priority tied to the infrastructure pipeline running ahead of the Brisbane 2032 Olympic and Paralympic Games.
Each of those points the same way. With Australia's commercial insurance market still firmly in soft territory and both branch manager roles filled from within earlier this year, Arch is treating the down cycle as the acquisition window rather than the defensive one. Brokers get the benefit of that on the way in. The question that could be worth asking at renewal - in a market where capacity has been arriving quickly - is what the line looks like on the way out.
