Commonwealth Bank of Australia Blocks Crypto-Related Purchases
Virtual and cryptocurrencies such as Bitcoin have yet to meet a minimum standard of regulation, reliability, and reputation.
Due to the unregulated and highly volatile nature of virtual currencies, customers will no longer be able to use their CommBank credit cards to buy virtual currencies. This will come into effect as of 14 February 2018.
Our customers can continue to buy and sell virtual currencies using other CommBank transaction accounts, and their debit cards.
We have made this decision because we believe virtual currencies do not meet a minimum standard of regulation, reliability, and reputation when compared to currencies that we offer to our customers. Given the dynamic, volatile nature of virtual currency markets, this position is regularly reviewed.
The restriction on credit card usage for virtual currencies will also apply to Bankwest credit cards. Source
