More than one million Australians are slated to switch banks by mid-2027 as ANZ's acquisition of Suncorp Bank progresses. The $4.9 billion takeover will see Suncorp Bank customers transition to ANZ, significantly expanding ANZ's footprint in the home loan market and making it Australia's third-largest mortgage lender.

The transition affects approximately 1.2 million Suncorp Bank customers. While ANZ first announced its intention to acquire Suncorp Bank in 2022, the deal faced considerable regulatory hurdles. The Australian Competition and Consumer Commission (ACCC) initially blocked the acquisition in August 2023, citing concerns that it could reduce competition within Australia's already concentrated banking sector, dominated by the 'Big Four' banks: Commonwealth Bank, Westpac, NAB, and ANZ.

However, the Australian Competition Tribunal overturned the ACCC's decision in February 2024, paving the way for the transaction. Treasurer Jim Chalmers ultimately approved the $4.9 billion deal in June 2024, deeming it to be in the national interest. The approval was contingent on several conditions, including a three-year moratorium on regional branch closures and a commitment to maintaining employment levels, ensuring no net job losses as a result of the merger.

Economic director at Compare the Market, David Koch, described the transition as a substantial change for many Australians, potentially impacting customers ranging from everyday account holders to those with mortgages and other loans. He advised customers to use the period leading up to the June 2027 transition to review their financial arrangements, including home loans and savings options, suggesting that loyalty may not always result in the best deals.

ANZ Queensland managing director and Suncorp Bank chief executive Bruce Rush stated that the transition process would be managed carefully, providing customers access to ANZ's broader network of specialists and branches. He assured customers that the transition would be straightforward, safe, and well-supported.

This consolidation follows other recent shifts in the Australian retail banking market. Global banking giant HSBC announced in July its withdrawal from the Australian retail banking sector after nearly four decades, fueling discussions about competition and the diminishing number of major players. Customer reactions online expressed concern about the trend towards fewer major banking entities.

In a move potentially aimed at increasing competition, London-based digital banking service Revolut received approval for an Australian banking license in July. Revolut, which already serves about one million Australians with its digital payments app, will now be able to accept deposits as an Australian bank and expand its service offerings, including savings and lending.
