Does Commonwealth Bank Allow Crypto Transactions?
Commonwealth Bank of Australia (CBA) does not currently offer direct cryptocurrency trading services. Customers cannot buy Bitcoin or other crypto directly through CBA’s platform, but they can transfer funds to licensed cryptocurrency exchanges.
However, CBA has implemented specific policies designed to reduce risks associated with crypto transactions, including monthly limits and potential transaction delays or declines.
Commonwealth Bank Cryptocurrency Policy
As of June 8, 2023, Commonwealth Bank introduced measures intended to protect customers from cryptocurrency-related scams and fraud:
- Monthly Transfer Limit: Transfers to cryptocurrency exchanges are capped at AUD 10,000 per calendar month.
- 24-Hour Holds: Certain crypto-related payments may be placed on a 24-hour hold.
- Transaction Declines: Payments identified as potentially high-risk may be declined outright.
These policies are designed to safeguard customers by minimizing exposure to cryptocurrency scams and fraud.
