How to Buy Crypto With a Bank Transfer (ACH, SEPA, Faster Payments, Wire)

Buying crypto with a bank transfer means moving currency from your bank into your exchange account over a domestic payment rail and then placing the order from the cash balance, which is normally the cheapest way to fund an account and differs from card funding mainly in speed and in the withdrawal holds that follow.

The two-step shape is the part people miss. Funding and buying are separate actions, and each has its own cost.

Why bank rails cost less

A card payment carries interchange, a processor's margin, and reversal risk, and the exchange prices all three into a percentage fee. A domestic bank transfer carries almost none of that, so exchanges commonly pass it through at no charge.

The published numbers show the gap plainly. As of September 2026, Kraken lists US dollar ACH deposits, euro SEPA deposits, and British pound Faster Payments deposits as free, against $0.25 plus 3.75% for a US dollar debit card deposit (source: Kraken support, cash deposit methods, fees and processing times). That is the general shape across regulated exchanges, and the card comparison is set out in full in Credit card vs bank transfer.

Funding is only the first cost. The trading fee and the spread apply when you place the order, whichever rail brought the money in.

ACH in the United States

ACH is the American batch clearing system, used for direct deposit and bill payment. On exchanges it is normally linked through a bank-connection provider rather than by entering account numbers, which is why linking takes a minute and later transfers take seconds to initiate.

As of September 2026, Kraken lists US dollar ACH deposits as free and near-instant in crediting, with a seven-day withdrawal hold applied afterwards (source: Kraken support). The hold is the important half of that sentence and is covered below.

SEPA in the euro area

SEPA is the euro payment area's transfer scheme, covering domestic and cross-border euro payments across participating countries on the same terms. SEPA Instant settles in seconds where both banks support it, and standard SEPA settles over business days.

As of September 2026, Kraken lists euro SEPA deposits as free, arriving in zero to three business days or instantly, with no withdrawal hold (source: Kraken support). No hold on a free rail is the best combination available to a euro-area buyer, and it is why SEPA is usually the default recommendation for anyone in Germany, France, or the rest of the area.

Faster Payments in the United Kingdom

Faster Payments is the British near-real-time rail. As of September 2026, Kraken lists British pound Faster Payments deposits as free, arriving in zero to one business day, with no withdrawal hold (source: Kraken support). Practical experience of the rail is usually a matter of seconds rather than days. Which exchanges serve British residents is on United Kingdom.

Wires

A wire is a single, individually processed transfer rather than a batched one. It is final on arrival, which is why exchanges treat it differently from ACH.

As of September 2026, Kraken lists US dollar FedWire deposits through its named bank partner as free with zero to one business day processing and no withdrawal hold, US dollar SWIFT deposits through one partner as free over one to three business days, and SWIFT deposits through another partner at 3 USD over one to five business days (source: Kraken support).

The exchange charging nothing does not mean the transfer is free. Your own bank usually charges for sending a wire, and international wires can lose value to intermediary bank fees and currency conversion along the way. For a large purchase the absence of a hold often justifies the cost.

Domestic rails outside the big three

Local systems frequently beat international ones. As of September 2026, Kraken lists iDEAL deposits in the Netherlands as free and near-instant with no hold, Canadian dollar Interac e-Transfer as free over zero to one business day, and Australian dollar PayID as free and near-instant (source: Kraken support).

Withdrawal holds are the real trade-off

Crediting speed and withdrawal freedom are different things. An exchange that credits a deposit instantly still bears the risk that the payment is reversed later, and it manages that risk by locking withdrawals for a period.

Kraken's published figures make the pattern visible.

So the cheapest fast rail is not always the one that lets you move coins soonest. If your intention is to buy and then withdraw to a wallet you control, an irreversible rail with no hold is worth more than a free one with a week-long lock. If you are leaving the balance on the exchange anyway, the hold costs you nothing. Moving coins off afterwards is covered in Move crypto off exchange.

What to have ready

Bank funding is only available on a verified account, because a fiat rail brings the exchange inside banking regulation. Expect to complete kyc before any deposit is accepted, as described in What is KYC.

Check the currency as well as the country. An account denominated in one currency receiving another triggers a conversion somewhere, and the rate applied is rarely the one you looked up.

Where to check what is available

Rails vary by exchange and by jurisdiction, and both have to line up. The ranked list for your location, with a cost estimate against each exchange, is on Buy Bitcoin and the other pages under Where to buy. To see which venues serve your jurisdiction at all, use Exchanges available in United States or the equivalent for your country. Operator detail sits on Kraken, Coinbase, and Bitvavo, and Compare sets two venues against each other across purchase sizes.

Frequently Asked Questions

Is a bank transfer really free?

The exchange's charge is often zero on domestic rails, and Kraken's published schedule lists ACH, SEPA, and Faster Payments deposits as free as of September 2026. Your own bank may still charge for wires, and the trading fee and spread on the purchase itself are separate costs.

How long does the money take to arrive?

It depends on the rail. Instant systems such as SEPA Instant, Faster Payments, iDEAL, and PayID move in seconds to a day. Standard ACH and standard SEPA settle over business days, and international SWIFT wires can take up to five.

Why can I not withdraw my coins straight after depositing?

Because reversible payment rails let the sender claw the money back after the coins have left, exchanges apply a withdrawal hold to newly deposited funds. On Kraken that is seven days for ACH and none at all for SEPA, Faster Payments, or wires, as of September 2026.

Can I use someone else's bank account?

Generally no. Exchanges require the funding account to match the account holder, because a name mismatch breaks the anti-money-laundering trail that aml rules require them to maintain. Deposits from third parties are usually returned.

Which rail should I use for a large purchase?

A wire is usually the better fit at size, because it arrives without a withdrawal hold and is final on receipt. Weigh your own bank's sending fee against the cost of having the balance locked, and check whether your exchange applies deposit minimums on that rail.
