ACCC Escalates IAG-RACI WA Insurance Merger to Phase 2 Review Over Market Concentration Concerns

The Australian Competition and Consumer Commission (ACCC) has initiated an in-depth Phase 2 review of Insurance Australia Group's (IAG) proposed acquisition of RAC Insurance (RACI). This move indicates significant regulatory scrutiny over the potential impact on competition within Western Australia's insurance sector. The ACCC's concern centers on market concentration, specifically regarding motor vehicle and home and contents insurance in the state. This represents a key test for the ACCC's new formal merger control regime.

The acquisition combines "two of the biggest insurers in Western Australia," stated the ACCC chair, highlighting the regulator's core concern. A Phase 2 review signifies an intensive investigation into the deal's competitive effects, moving beyond initial assessments. The ACCC's latest data shows the rarity of such escalations; in Q1 2026, the ACCC processed 50 merger notifications, approving 39 at Phase 1 and escalating only two to Phase 2 before the IAG-RACI case. This deeper review process can extend for up to 90 business days, requiring extensive data and submissions from involved parties and the public.

For IAG, this escalation means a prolonged and forensic examination of the proposed deal, carrying increased regulatory costs and uncertainty. The ACCC's primary concern remains the potential reduction in competition if two major players consolidate their presence in the Western Australian market. This could impact pricing and product choice for consumers in motor and home insurance. For the broader insurance industry, this decision underscores the ACCC's firm stance under its new mandatory merger control framework, especially when dealing with transactions involving dominant market participants. This marks IAG's second attempt to secure approval for this specific acquisition.

All eyes are now on the ACCC's detailed findings, which will shape future merger activity and competition within Australia's financial services sector.
