During the first quarter of 2026, commercial insurance pricing across the Pacific market dropped by 12 per cent, producing the most buyer-friendly renewal conditions observed in recent years. However, risk management specialists at Marsh warn that falling premium costs are masking a severe underinsurance deficit, as property replacement and reconstruction valuations continue to outpace downward rate adjustments.
Persistent Macroeconomic Pressures and Escalating Reconstruction Costs
While commercial insurance rates have softened, underlying economic inflation across key regional markets remains elevated:
-
Australia: Headline Consumer Price Index (CPI) inflation reached 4.6 per cent in the year to March 2026 before easing to 4.0 per cent in May. However, the Reserve Bank of Australia’s core measure—the trimmed mean—unexpectedly climbed to 3.6 per cent over the same period.
-
New Zealand: CPI inflation stood at 3.1 per cent through March 2026, remaining above the central bank’s target ceiling.
-
Construction Sector: Construction cost inflation is projected to hit 6 per cent by mid-2026, driven by chronic labor shortages, ongoing supply chain bottlenecks, and elevated material costs.
Key construction inputs are seeing acute cost pressures. Plastic piping products have surged by up to 36 per cent, alongside sustained price increases for concrete, cement, sand, copper, and electrical componentry. Additionally, Middle East maritime disruptions along the Strait of Hormuz continue to keep fuel and freight rates elevated—a major strain on the construction sector, where over 75 per cent of heavy equipment relies on diesel fuel.
Business Interruption Risks and the “Average Clause” Penalty
In addition to physical asset undervaluation, legacy business interruption (BI) indemnity limits—set two to three years ago—are increasingly insufficient to cover contemporary, extended supply chain delays and prolonged restoration timelines.
Illustrative Example: A commercial property insured for $10 million sustains $5 million in fire damage. If an adjuster determines the true replacement cost is $20 million, the asset is 50 per cent underinsured. Applying the average clause reduces the final payout by half to $2.5 million, leaving the insured business to fund the remaining deficit.
To mitigate these structural liabilities, advisory experts recommend that corporate policyholders commission professional asset valuations every two to three years and perform annual reviews of their business interruption indemnity windows.
