Do you believe advanced diagnostic tools help businesses effectively manage their insurance costs?

Aon has introduced new property and casualty risk diagnostic tools designed to help commercial clients manage shifting insurance costs. The move aims to provide data-driven insights as market conditions fluctuate.

Why it matters

Property and casualty insurance markets are currently trending in opposite directions, creating uncertainty for commercial coverage budgets. These diagnostics are intended to help businesses navigate these costs with evidence-based risk mitigation strategies.

US commercial property premiums fell 1.2% in the first quarter of 2026, while auto liability rates jumped by 7% to 25%. Umbrella liability rates also saw increases ranging from 10% to 20%.

The players

Aon

A global professional services firm that provides risk, retirement, and health consulting services to commercial clients.

Aon Global Risk Consulting

The internal engineering and advisory division of Aon tasked with delivering technical risk assessment services.

The details

The new property diagnostic tool utilizes modeled and historic loss estimates to assess both catastrophe and non-catastrophe risks. Meanwhile, the casualty tool analyzes a client's own claims data against a proprietary database to benchmark performance. These tools shift the broker's role from simple insurance placement toward providing ongoing, engineering-led advisory services.

Q1 2026: Commercial property premiums saw a 1.2% decline.
July 2026: Aon previously released an AI-focused risk diagnostic tool.
September 29, 2026: Aon launched the new property and casualty diagnostic tools.
2027: International rollout of the casualty diagnostic tool is planned.

Money Landscape

This launch follows the pattern set by Aon's July 2026 AI risk diagnostic release. It signals a broader industry trend toward brokers providing evidence-based consulting to offset volatility in commercial insurance pricing.

Businesses managing fluctuating property and casualty premiums may be offered these tools as part of their advisory services. Discuss with your professional insurance consultant how data-driven risk modeling could potentially influence your upcoming renewal negotiations.

The takeaway

Insurance markets are currently bifurcated, with some costs falling while liability premiums experience double-digit percentage increases. Business owners should review their current risk exposure and discuss potential mitigation strategies with a qualified insurance professional before their next policy renewal.
