According to Coinbase, Coinbase has filed a formal complaint with the Australian Parliament, accusing the country's four largest banks—Commonwealth Bank, Westpac, ANZ, and NAB—of systematically refusing to provide financial services to legitimate crypto companies. This account closure has become systemic, and since the four banks control the majority of trading accounts and payment channels, such actions effectively constitute an illegal regulatory ban. Data shows that in 2021, 60% of fintech companies faced bank denials. Coinbase is calling on legislators to mandate five transparency measures for banks, including informing them of the reasons for account closures, ensuring internal dispute resolution procedures, providing 30-day advance notice, and self-certification for compliance. These measures were proposed by the Australian Financial Supervisory Commission in 2022 but have not yet been enacted.
