Westpac caps crypto exchange payments at A$10,000 a month

What happened

Westpac customers who fund crypto purchases by sending Australian dollars from the bank to an exchange will face a monthly ceiling starting Dec. 1. In a notice on its website, the lender said it may cap payments it reasonably identifies as going to cryptocurrency exchanges at a cumulative A$10,000 per customer for each calendar month.

The allowance is counted across a customer's relevant Westpac accounts rather than applied transaction by transaction. Westpac listed online banking, the Westpac app, and credit and debit cards among the channels where the limit may apply, and said the covered products may change from time to time. Holders of a joint account are each treated as having a separate A$10,000 allowance.

Once a customer's total reaches the cap, additional exchange payments may be rejected until the next calendar month begins. Westpac said it will not offer exemptions or lift the limit for anyone, while also acknowledging it cannot guarantee that a transfer above A$10,000 will not get through. From the same date, paying an exchange in a branch will not be supported.

Money moving in the other direction is unaffected. Westpac said withdrawals from exchanges into its accounts are not changing, and directed customers to their exchange for any limits on that side.

Why it matters

The policy puts a fixed dollar figure on Westpac's existing approach to crypto payments, and it applies without a route to appeal or a higher tier for larger users. The customers most exposed are those who move more than A$10,000 a month into crypto through the bank, since the bank has ruled out exceptions. Because Westpac has not published the list of exchanges it covers, a customer cannot know in advance whether a particular transfer will count toward the monthly total, and coverage can also depend on the payment details an individual exchange accepts. Westpac describes enforcement in discretionary terms: the limit applies where the bank identifies an exchange payment made through a covered product and channel.

What the data shows

The headline figure is A$10,000 per customer per calendar month, aggregated across relevant Westpac accounts and across the channels the bank applies the policy to, including online banking, the app and cards. The rule takes effect on Dec. 1. Westpac pointed to a 46% share of reported scam losses involving crypto, drawn from the National Anti-Scam Centre report published in March 2026. Its earlier crypto payment trial was announced in May 2023, and Commonwealth Bank of Australia's planned A$10,000 monthly cap was reported in June 2023.

Background

Westpac framed the change as a response to scams, saying criminals increasingly push victims toward crypto because funds are difficult to recover once sent. The bank cited the National Anti-Scam Centre's Targeting Scams Report 2025, published in March 2026, which it said showed crypto featured in 46% of reported scam losses last year. Westpac has acted in this area before: in May 2023 it said it had begun trialling protections for some crypto payments, citing investment scams, with blocks to be rolled out in phases. The bank is also not the first Australian lender to land on this number. Unchained reported in June 2023 that Commonwealth Bank of Australia planned to hold customers' payments to crypto exchanges to A$10,000 per calendar month. CryptoSlate and Unchained both covered the new Westpac policy.

What is still unclear

Several details remain open. Westpac has not published which exchanges fall under the limit, so the scope of the policy is not publicly checkable. The bank said covered products may vary over time, leaving the full set of affected channels subject to change, and it acknowledged that payments above the threshold may still be processed in some cases. How consistently the cap is applied will depend on how the bank identifies an exchange payment at the moment it is made.

What to watch

The practical test comes after Dec. 1, when customers who routinely fund exchanges with more than A$10,000 a month encounter the cap. Also worth watching is whether other Australian lenders adopt a similar fixed limit, whether Westpac ever publishes its list of covered exchanges, and how customers and regulators respond to a rule that has no exemption process.
