Wire Transfers – How Do They Work, and How Long do They Take?

What is a wire transfer

A wire transfer is an electronic, bank-to-bank movement of money between two parties, arranged through one or more banks or licensed non-bank providers. No physical cash moves. Instead, the institutions exchange instructions, the amount, the currency, and the recipient's account details, and the funds settle between them.

So what is a bank wire transfer, specifically? It is simply a wire transfer where both institutions are banks, rather than a non-bank provider such as a licensed money transfer service. An overseas bank transfer is the most common example. In everyday use, bank wire transfer and wire transfer mean the same thing.

The sender funds the transfer up front, from a bank account or in cash, before it is released. Wire transfers can be domestic (same country) or international (across borders), and can run bank-to-bank or through a non-bank provider.

What is the SWIFT network

The SWIFT network is a secure messaging service used by financial institutions to exchange information, including instructions for wire transfers. Crucially, SWIFT doesn't move or settle the money itself. It's the secure messaging layer that member institutions use to exchange payment instructions, while the funds settle separately between the banks and their correspondents. SWIFT describes itself as connecting more than 11,500 members worldwide, and it carried well over 53 million payment messages a day in 2024, which is why it underpins most international wire transfers.

How does a wire transfer work, and how do you send one

Sending a wire transfer is straightforward once you have the right details. Here is how to send a wire transfer, step by step, and what happens behind the scenes while it processes. To wire the money, you:

• Choose a bank or licensed provider (compare speed, fees, and ease).
• Gather the details: your account number, and the recipient's name, contact, account number, and SWIFT code.
• Fill in and submit the wire transfer form, online or in branch.

Once submitted, the sending institution passes on the payment instructions, and the funds settle between the banks. Some payments go directly between the two banks, while others pass through one or more correspondent banks, which is part of what affects how long an international wire takes. We cover realistic timelines in the next section.

How long does a wire transfer take

While money transfers made over the wire are a fast way of moving money, they can take some time. That’s why it is important to have a fair idea of the transmission time before sending an urgent wire.

• Local Singapore bank transfers: FAST transfers between participating institutions are generally almost immediate and available 24/7. Other local methods, such as MEPS+ or GIRO, run on different processing windows
• International wire transfers: Processing time depends on the sending bank, the receiving bank, the correspondent route, the currency, cut-off times, screening, and the destination. A bank or provider may quote roughly 2 to 5 business days, though actual delivery can be faster or slower

What information is needed for a wire transfer

A wire transfer typically requires the following information:

• Sender’s full name and phone number
• Recipient’s full name, phone number, address, bank name and address, bank account number and account type, such as savings or current
• For international transfers, the recipient’s BIC/SWIFT code and/or International Bank Account Number (IBAN). The BIC is a universal identifier for banks and other financial institutions. The IBAN is an alphanumeric code with up to 34 characters that identifies individual bank accounts for the purpose of sending and receiving cross-border payments. IBAN is used in many countries, particularly across Europe and other participating markets; Singapore bank accounts do not generally use IBANs.

The chosen financial institution might request additional information from the sender such as a government-issued ID, such as a passport or driver’s licence, email address, proof of address, such as a recent utility bill or bank statement, proof that they are the holder of the bank account from which the funds will be sourced, and the reason for the transfer.

Wire transfer fees and how to keep them low

Wire transfers are not free, and the total cost has more moving parts than one headline fee. For an outward telegraphic transfer from a Singapore bank in 2026, expect a cable or SWIFT charge of around SGD $20 (often SGD $35 in branch), plus a handling commission that scales with the amount, commonly SGD $10 to SGD $120. Correspondent or agent banks can each deduct a fee, and the bank's FX margin, baked into your quoted rate, is often the largest cost and the easiest to miss. Charges vary by bank, so check the current schedule.

Because that FX margin is usually the biggest hidden cost, it pays to compare rails before you send. Aspire (https://aspireapp.com/global-payments) helps finance teams managing recurring cross-border payments see the full cost of each transfer before they confirm, with the FX rate and fees shown upfront, so there are no surprises at reconciliation. Running those payments from one multi-currency account also means fewer manual steps, one place to track spend, and no switching between separate bank portals for each transfer.

Here are some more tips on how to wire money in the most cost-effective manner:

• Compare the fixed and variable fee structure before deciding whether consolidating payments actually lowers your total cost. Batching isn't always cheaper: it can concentrate risk, affect cash timing, run into approval or limit constraints, and doesn't suit invoices due at different times
• Provide correct information to prevent a cancelled request. Retrieving funds held up due to an error can be expensive as well as lengthy. Also, many financial institutions offer customers a special rate, which is not guaranteed when they make a fresh transfer request
• When sending money in a foreign currency, it is important to keep an eye on exchange rate fluctuations. Furthermore, most banks assign a fixed exchange rate upfront and might add an exchange fee. Looking at other financial service providers might help the sender get a lower exchange rate or avoid the exchange fee

Wire transfers vs local bank transfers

People use wire transfer and bank transfer interchangeably, but they are not the same. A bank transfer is any electronic movement between accounts, including instant local rails like FAST and PayNow. A wire transfer is a specific type of bank transfer, usually routed through the global banking network over SWIFT, and most often used across borders. So every wire transfer is a bank transfer, but not every bank transfer is a wire transfer.

The practical difference is speed, cost, and reach. In Singapore, FAST (Fast and Secure Transfers) is an electronic funds transfer service run by the Association of Banks in Singapore that moves SGD between participating banks and institutions almost instantly, around the clock, and PayNow runs on top of it. These local transfers are usually free and settle in seconds, with FAST carrying a public limit of SGD $200,000 per transaction, though banks may set lower caps and non-bank e-wallet transfers are usually capped at SGD $5,000. A wire transfer, by contrast, reaches almost any bank in the world, but takes longer and carries cable, handling, and correspondent-bank fees plus an FX margin.

For an international or overseas bank transfer from Singapore, a traditional wire over SWIFT is only one of several routes. Payments can also travel over local payout rails in the destination country, card networks, specialist provider networks, or bilateral instant-payment links, Singapore already connects PayNow to Malaysia's DuitNow for cross-border transfers, for example. SWIFT wires tend to be the slowest and most fee-heavy of these options. If speed and cost matter more than reach, a local rail, an instant-payment linkage, or a multi-currency account that pays in the destination currency is often the better call.

How to wire money to Singapore

Receiving an international wire into a Singapore account is the same process in reverse: the overseas sender needs your exact details. Give them your registered business or account name, your account number, and your bank's SWIFT BIC. Some corridors also ask for the bank's full name and address, plus a reference or invoice number for reconciliation. For SGD payments from within Singapore, a PayNow UEN also works.

Inbound international wires usually take 1 to 5 business days, and sending or intermediary banks may deduct fees, so the amount that lands can be smaller than the amount sent. If you regularly collect in foreign currencies, receiving into a multi-currency account lets you hold USD or EUR without a forced conversion, so you convert when the rate suits you.

Alternatives to wire transfers

For payments that stay inside Singapore, a wire transfer is usually overkill. Faster, cheaper local rails handle most of it, and the right one depends on whether the payment is one-off or recurring:

• FAST and PayNow: near-instant, 24/7 transfers of Singapore dollars, with a FAST public limit of SGD $200,000 per transaction. Fees depend on your bank and account type, though many everyday transfers are free, so this is the usual default for one-off supplier or vendor payments
• MEPS+: MAS's real-time gross settlement system for high-value, time-critical SGD transfers between banks. It settles payments individually and same-day within system hours, and is used mainly by financial institutions and large corporates rather than for everyday payments
• GIRO: a direct-debit system for recurring bills like rent, payroll, or subscriptions. Two timelines matter here. Setting up the mandate is a one-time step, and eGIRO has cut this down from the old paper process, corporate approvals can complete in under 48 hours in participating cases. Once it's live, individual payments run in batches on business days and take up to 3 business days to clear, pausing on weekends and public holidays
• Cheques: on the way out for businesses. Singapore banks stopped issuing new SGD corporate cheque books from 1 January 2026, and will stop processing SGD corporate cheques from 1 January 2027. EDP and EDP+ were introduced in 2025 as electronic alternatives for deferred-payment use cases, so cheques aren't worth building your payments around

How Aspire makes cross-border payments simpler

Most of what makes a wire transfer painful comes down to two things: the wait, and the cost you cannot see until it is gone. The upfront fee is easy to spot, but the exchange rate markup is where the real money leaks, and by the time it shows up the transfer is already on its way.

Aspire is a finance platform built for founders paying and getting paid across markets, and it closes both gaps:

• See the full cost before you confirm: Aspire displays the applicable FX rate and transfer fees before confirmation
• Hold and pay in multiple currencies: open a multi-currency account in SGD, USD, EUR, and GBP, and pay suppliers in the currency they invoice in, so you avoid a forced conversion on every payment
• Send same-day and settle like a local: local transfers in major currencies are free and typically land instantly or within a business day
• Run everything from one login: manage global payouts, cards, and expenses in one place instead of a separate bank portal for each transfer

For a business making regular cross-border payments, Aspire turns a slow, opaque wire into something you can actually plan around.

Conclusion

A wire transfer remains one of the most reliable ways to move money worldwide, especially for large or urgent payments local rails cannot handle. The trade-off is cost and, for international transfers, a wait of up to five business days. Knowing the wire transfer meaning, the realistic timelines, and where the fees hide, particularly the FX margin, helps you pick the right rail for each payment.

If cross-border payments are a regular part of running your business, moving them onto a multi-currency account with transparent FX and upfront fees takes the guesswork out of every transfer.
