ACCC Moves IAG-RAC Insurance Deal to Phase 2 Citing Market Concentration Risks
The ACCC has escalated its scrutiny of Insurance Australia Group’s proposed takeover of RAC Insurance, citing potential substantial lessening of competition in Western Australia’s motor and home insurance markets.
- ACCC flags significant competition issues in WA motor and home insurance sectors
- IAG would underwrite RAC-branded insurance products post-acquisition
- Phase 2 review includes potential impact on smash repair services
- Public submissions open until 4 May 2026
- Acquisition previously rejected under informal merger regime in 2025
ACCC Targets WA Insurance Market Concentration
The Australian Competition and Consumer Commission (ACCC) has determined that Insurance Australia Group’s (ASX:IAG) planned acquisition of RAC Insurance (RACI) warrants a detailed Phase 2 review, citing concerns the deal could substantially diminish competition in Western Australia’s insurance market. The move escalates regulatory scrutiny following the ACCC’s earlier refusal to clear the deal under the previous informal merger rules in late 2025.
RAC Insurance, owned by the Royal Automobile Club of Western Australia, dominates both motor vehicle and home and contents insurance in the state. IAG, which already operates extensively in WA under the NRMA brand, would take on underwriting for RAC-branded policies if the acquisition proceeds, effectively merging two of the region’s largest insurers.
Competition Risks Extend Beyond Insurance
ACCC Chair Gina Cass-Gottlieb emphasised the potential market impact, noting the acquisition could significantly reduce competition in both motor and home insurance sectors. The regulator is also examining the transaction’s possible effects on smash repair services, an ancillary market linked to motor insurance claims.
The Phase 2 review process allows the ACCC up to 90 business days to assess the acquisition’s impact comprehensively, including accepting submissions from interested parties until 4 May 2026. This rigorous examination under the new formal merger regime reflects heightened regulatory vigilance over deals that could reshape market dynamics.
IAG’s Expanding Footprint in Personal Insurance
IAG is a major player in Australia and New Zealand’s general insurance space, underwriting a broad portfolio of personal and commercial insurance products across multiple brands such as NRMA, Swann, CGU, and WFI. In Victoria, it already partners with RACV to underwrite RACV-branded motor and home insurance, highlighting its strategic use of brand partnerships to expand market reach.
The proposed acquisition would consolidate IAG’s position in WA, where it primarily offers insurance under the NRMA brand. The deal excludes RAC’s roadside assistance and other non-insurance businesses, focusing solely on the insurance underwriting operations.
This development follows a broader trend of increased regulatory scrutiny on major Australian mergers, similar to the ACCC’s recent decision to escalate Ampol’s acquisition of EG Australia to a Phase 2 review over competition concerns in fuel retailing markets Ampol’s EG Australia deal. Such regulatory actions underline the ACCC’s commitment to closely monitor market concentration risks across sectors.
Bottom Line?
The ACCC’s Phase 2 review introduces uncertainty around the acquisition’s fate, with potential implications for market competition and deal structure in WA’s insurance industry.
Questions in the middle?
- Will the ACCC impose conditions or require divestments to clear the acquisition?
- How might this deal reshape competitive dynamics among insurers in Western Australia?
- What impact could the acquisition have on pricing and service quality for WA insurance customers?
