How to read this page
Issuer policies are set per institution and per card product, change without announcement, and are rarely published in full. What follows summarises publicly reported positions. It is a starting point for a phone call to your own bank, not a substitute for one — and your bank's answer about your card is the only authoritative one.
People blame exchanges for failed card purchases. In most cases the exchange never saw a problem: it forwarded an authorisation request and your bank said no. Several large issuers decided years ago that crypto exchange purchases were an unacceptable risk on a credit line, and those decisions still govern what happens at checkout today.
The US issuers
| Issuer | Credit card position | Notes |
|---|---|---|
| Chase | Blocked | Began declining crypto-related credit card transactions in 2018; policy not reversed for the credit portfolio. Separate Coinbase integrations exist for funding and rewards. |
| Bank of America | Blocked | Introduced a block in early 2018 across personal and business credit cards at known crypto exchanges. |
| Capital One | Blocked | Systems flag merchant category codes associated with crypto exchanges and decline them as high risk. |
| American Express | Generally permitted | Applies dollar limits on spending at crypto merchants within a rolling period; individual declines still occur. Exchange acceptance of Amex is limited. |
| Discover | Limited | Works through specific processors at some exchanges; narrower acceptance than Visa or Mastercard. |
| Wells Fargo, Citi | Varies | Positions have shifted over time and differ by product. Confirm directly before attempting. |
Why banks blocked it in the first place
Three reasons, and they are all rational from the bank's side. Credit risk: lending money to buy a volatile asset, where a sharp fall leaves the borrower holding a depreciated asset and a full balance. Chargeback exposure: card payments can be disputed, but crypto cannot be recovered, so the bank ends up in the middle of an unresolvable dispute. And anti-money-laundering scrutiny, where transactions to exchanges carry higher regulatory attention than average retail spending.
Notice that all three apply much less to debit cards. There is no credit extended, the customer's own funds are used, and the dispute exposure is lower. That asymmetry explains the entire pattern of issuer behaviour in this space and is why our debit card guide is the more practical one for most readers.
The cash advance question
Where a credit card purchase does go through, the next question is how it is coded. A transaction treated as a cash advance carries a separate fee — commonly a percentage with a minimum — and interest from the transaction date with no grace period, usually at a higher rate than the purchase APR.
Whether your bank applies this depends on the merchant category code used by the exchange's acquirer and on the bank's own rules, which vary between card products at the same institution. There is no way to determine it from outside. The only reliable method is to call the number on the back of your card and ask the question directly: are cryptocurrency exchange purchases coded as a purchase or a cash advance on this account?
The two-minute call that saves the most money
Ask three questions and write down the answers. Are crypto exchange purchases permitted on this card? Are they coded as a purchase or a cash advance? Is there a limit on spending at crypto merchants?
Frontline staff can usually answer the first two immediately. The third is often a policy they can look up. Doing this before a large purchase routinely saves more than the exchange's entire fee — and doing it after a purchase that settled as a cash advance saves nothing at all, because the interest has already started.
Outside the United States
The UK has the most restrictive retail banking environment among the major markets. Several large UK banks have limited or blocked payments to crypto platforms, applying daily caps, blocking credit card purchases entirely or restricting transfers to a list of approved platforms. Positions differ between banks and have changed repeatedly, so check your own bank's current published stance, and confirm any crypto firm you plan to pay on the FCA register.
Across the EEA, card acceptance is generally more straightforward, and SEPA Instant provides a cheap alternative that sidesteps card rules entirely. In Australia, major banks have applied their own limits on payments to crypto platforms, while PayID and Osko provide fast local rails — see the Australia guide. In Nigeria, the relationship between banks and crypto platforms has been through several phases and remains the central practical constraint, covered in the Nigeria guide.
Debit versus credit, once more
If you take one thing from this page: use a debit card. It is accepted at more exchanges, blocked by fewer banks, never coded as a cash advance, and priced the same or lower. Almost everyone searching for which credit cards allow crypto purchases would be better served by a debit card and a five-minute check of their bank's daily limit.
The exception is if you specifically want the rewards, in which case the answer is not to buy crypto with a rewards card but to get a card that pays rewards in crypto for ordinary spending. That is a different product entirely — see crypto credit cards and the Coinbase One Card review.
What to do when your bank blocks you
First, confirm it is actually a block rather than one of the other eleven causes of a failed card payment — our decline guide lists them in order of likelihood, and an address mismatch or a timed-out authentication step looks identical from your side.
If it is a block, change the rail. Instant bank transfers exist in most developed markets — Faster Payments in the UK, SEPA Instant across the euro area, PayID and Osko in Australia — and they are not subject to merchant category rules. They also cost substantially less than cards, which means a block your bank imposed may save you money.
A debit card from a different institution is the other straightforward option, since these policies are set per bank. What we would avoid is any service promising to process a payment your bank deliberately refused. Those routes exist, they cost more, and they replace a solvable payment problem with a counterparty you cannot evaluate.
Keeping this page useful
Issuer policies are among the fastest-moving facts on this site and among the least publicly documented. Banks rarely announce these decisions, and when they change, the change usually surfaces through customer experience rather than a press release.
So treat every row above as a prompt rather than a conclusion. If your bank's behaviour differs from what is described here, your bank is right and we would genuinely like to know — you can reach us through the contact page. Meanwhile, the one action that works in every case is the phone call, and it takes less time than reading this paragraph twice.
