What are SWIFT payments and how do they work?

SWIFT payments let you send money internationally through the Society for Worldwide Interbank Financial Telecommunication (SWIFT) network. This system helps banks communicate securely with each other to transfer money across borders, ensuring your transactions are verified, recorded accurately, and completed between countries.

If you're managing cross-border vendor payments, sending payroll abroad, or investing in overseas markets, you need to understand how SWIFT works and what it costs.

What is SWIFT?

The SWIFT network is a messaging system that connects over 11,000 financial institutions across more than 200 countries. It doesn't actually move your money. Instead, it provides a secure way for banks to exchange standardized information about financial transactions.

The system was created in 1973 and launched in 1977. Seven major banks formed SWIFT to replace the outdated Telex system, aiming to create standard formats for international banking messages.

Over the years, SWIFT has evolved significantly:

• Introduced SWIFT codes (BIC) in the 1980s
• Developed standardized message formats like MT and later XML-based MX formats
• Implemented enhanced security protocols
• Launched Global Payments Innovation (GPI) for faster, more transparent transactions

These changes mean your international payments now take days or hours instead of weeks, and standardized formats reduce the manual work your team does to reconcile cross-border payments.

What are SWIFT payments?

SWIFT payments are international money transfers that use the SWIFT network to send payment instructions between banks across borders. Unlike domestic transfers, SWIFT payments connect banks in different countries, often dealing with multiple currencies and regulations.

The SWIFT system uses standard formats for payment instructions so banks can communicate clearly and consistently.

Core components of SWIFT payment processing include:

• Standardized messaging format: SWIFT payments follow specific formats (like MT103 for customer transfers and MT202 for bank-to-bank transfers) to ensure all necessary information is organized consistently
• Global reach: With connections to over 11,000 financial institutions in more than 200 countries, you can send global payouts to almost any bank account worldwide
• Multi-currency support: The system handles payments in all major currencies and many minor ones, using standard codes and formats
• Security infrastructure: SWIFT uses multiple layers of encryption, authentication, and monitoring to keep your financial messages secure
• Traceability: Each SWIFT message gets a unique reference number so you can track your payment throughout the process
• Compliance features: Fields for regulatory information (like payment purpose) help support anti-money laundering requirements

What are SWIFT codes?

SWIFT codes, also called BIC (Bank Identifier Codes), are unique IDs assigned to financial institutions on the SWIFT network. These 8–11 character codes work like addresses, making sure messages go to the right bank. Each part of the code tells you something specific about the bank and where it's located.

A SWIFT code has four main parts:

1. Bank Code (4 characters): Identifies the bank (e.g., CHAS for JPMorgan Chase)
2. Country Code (2 characters): Shows the country (e.g., US for United States)
3. Location Code (2 characters): Indicates the city or region
4. Branch Code (3 characters, optional): Specifies a branch. If missing or "XXX," it's the main office

If you import or export goods, you'll need SWIFT codes when paying international suppliers or receiving funds from overseas customers. For instance, if you're a German auto parts manufacturer getting paid by a U.S. distributor, you'd provide your SWIFT code to ensure your payment arrives correctly. If you have employees in multiple countries, you'll also use SWIFT codes to route salary payments to them.

Here's an example SWIFT code breakdown:

• CHAS: Bank code for JPMorgan Chase
• US: Country code for United States
• 33: Location code for New York
• XXX: Main office (not a specific branch)

How do SWIFT payments work?

A SWIFT payment works by transmitting secure, standardized messages between banks, not by moving money directly. Your bank creates a payment instruction (typically an MT103 message) that routes through the SWIFT network to the recipient's bank, settling through correspondent banking relationships in 1–5 business days.

SWIFT only passes messages between banks. It doesn't actually move your money. When people talk about a "SWIFT transfer," they mean a payment that uses SWIFT messages for coordination, not funds moved by SWIFT itself.

International banking relies on Nostro and Vostro accounts. Both terms describe the same account from opposite perspectives:

• Nostro account:Our account with you—your bank's account at a foreign bank, usually held in the foreign bank's local currency
• Vostro account:Your account with us—the same account from the foreign bank's perspective

For example, JP Morgan might have a Nostro account at Deutsche Bank in euros. To Deutsche Bank, that's a Vostro account. These relationships let banks make international payments without needing offices in every country.

Here's how a SWIFT payment typically works:

• Message creation: Your bank creates a SWIFT message (often MT103 for customer payments) with all your payment details like amount, currency, and recipient information. MT103 is the standard SWIFT message type for single customer credit transfers and the most commonly used format for business-to-business international payments.
• Network transmission: This message travels securely through the SWIFT network to the recipient's bank, or through intermediary banks if there's no direct relationship
• Correspondent banking: If your bank and the recipient's bank don't have a direct relationship, the SWIFT network routes the payment through one to three intermediary banks, each adding time and fees. A transfer from a small U.S. bank to a regional bank in Southeast Asia, for example, might pass through two or three intermediaries.
• Account crediting: The recipient's bank receives and checks the message, then adds the funds to the recipient's account
• Confirmation: The recipient's bank receives the SWIFT message, credits the recipient's account, and may notify the sender's bank

Unlike domestic transfers (such as ACH payments in the U.S. or SEPA in Europe), SWIFT transfers rely on correspondent banking. This typically makes SWIFT transfers slower, taking 1–5 business days, and more expensive, since several banks may be involved.

Common delays happen during compliance checks, when using intermediary banks, or due to time zone differences affecting processing hours. Currency conversions and missing recipient information can also slow things down.

When do you need to use SWIFT payments?

You'll need SWIFT payments for almost any financial transaction that crosses international borders. If you import or export goods, you'll use SWIFT to pay overseas vendors or collect payments from international customers.

For example, if you're a U.S. manufacturer buying components from Taiwan, you'd use SWIFT to pay in the appropriate currency. If you have global operations, you'll rely on SWIFT to manage international cash flows.

Other common business scenarios include:

• Paying foreign contractors or service providers
• Paying international employees or expatriate staff
• Investing in overseas opportunities or real estate
• Paying dividends to international shareholders
• Settling cross-border merger and acquisition transactions

How to send a SWIFT payment

Sending a SWIFT payment follows the same general process as any international wire transfer. The key is having the right details ready before you start.

1. Gather your recipient's details: You'll need their full legal name, bank account number or IBAN, their bank's name and SWIFT/BIC code, and the purpose of payment if required for regulatory compliance
2. Log into your banking platform or visit your bank: Most business banking platforms support international wire transfers online. Small businesses may need to visit a branch for their first SWIFT bank transfer.
3. Enter the transfer details: Provide the recipient information, transfer amount, currency, and your preferred fee structure—OUR (you pay all fees), SHA (shared), or BEN (recipient pays)
4. Review and authorize the payment: Double-check the SWIFT/BIC code and account number, as errors can cause delays or returned payments
5. Track the transfer: Your bank will provide a reference number, and if it supports SWIFT GPI, you can track the payment in near-real-time with settlement in 1–5 business days

If you regularly send SWIFT money transfers, consider Ramp Bill Pay, which automates approvals and consolidates international wire transfers alongside your domestic payments.

What is the SWIFT payment process?

A SWIFT transfer moves through three stages: initiation, processing, and confirmation. How you manage each stage depends on your company's size.

• Initiation: You provide payment details to your bank
• Processing: Your payment instruction travels through the SWIFT network, potentially passing through intermediary banks
• Confirmation: The recipient's bank receives the funds and notifies the recipient

To start a SWIFT transfer, you'll need to give your bank these details:

• Recipient's full name and account number (or IBAN number, depending on country)
• Their bank's name and SWIFT/BIC code
• Transfer amount and currency
• Often, the purpose of payment and source of funds for compliance

Many countries also require information about where the money is coming from for regulatory reasons. Initiating SWIFT transfers also depends on your business size:

• Small businesses: You'll typically use online banking or visit a branch, with owner approval required for larger transfers. Compliance steps are straightforward, often with support from a relationship manager.
• Medium-sized enterprises: You'll use treasury systems linked to banks, with dual approvals for transfers. Your finance staff groups and schedules payments in batches.
• Large corporations: You'll rely on enterprise resource planning (ERP) systems with multi-level approvals and direct bank connections. Your treasury team manages relationships and runs compliance checks before sending payments.

Fees and costs of SWIFT transactions

SWIFT transactions typically include several fees that add up to your total cost:

• Sending bank fees ($20–$50)
• Receiving bank charges ($10–$20)
• Intermediary bank fees ($10–$30 per intermediary)
• Currency conversion costs, often hidden in a 1–4% markup over the mid-market rate

What you pay also depends on your business size and banking relationships:

Beyond business size, the payment cost model you choose also affects your total fees:

• OUR: You pay all costs (common in tech for contractor payments)
• SHA: You share costs with the recipient (common in manufacturing for supplier payments)
• BEN: The recipient pays all costs (frequent in retail when receiving payments)

To keep your SWIFT transaction costs down:

• Combine multiple payments to the same recipient
• Keep accounts in currencies you use often to avoid conversion fees
• Negotiate volume-based pricing with your bank

Watch out for intermediary bank charges. These hidden fees can reduce payment amounts by 10–30%, especially for transfers to certain regions.

Benefits of SWIFT

The SWIFT network connects over 11,000 institutions in more than 200 countries, so you can pay almost any business partner securely.

1. Transaction traceability: Each of your payments gets a unique reference number for tracking. For example, if you're importing pharmaceuticals, you can monitor exactly where your payment is, crucial when you need time-sensitive medical supplies.
2. Operational efficiency: Standardized formats let you automate much of the process, reducing manual work. If you run an international retail business, you can automate payments to hundreds of suppliers, cutting down on data entry and reconciliation time.
3. Regulatory compliance: Structured messaging includes fields for sanctions screening and anti-money laundering details. This helps you document transactions for audits and reduce compliance risks.

The standardized messaging formats also help eliminate confusion and reduce errors in your cross-border transfers. Different industries benefit in specific ways:

• Financial services: SWIFT's security infrastructure protects your high-value transfers from fraud and cyber threats
• Manufacturing: Standardized documentation speeds up your supply chain payments and reconciliation
• Healthcare: SWIFT's precision supports timely payments to your global medical suppliers

Drawbacks of SWIFT

SWIFT payments typically take 1–5 business days, and fees from multiple banks add up quickly.

Compared to domestic transfers or newer fintech options, SWIFT payments typically cost more.

Three major drawbacks you might encounter with SWIFT include:

1. Settlement delays in certain regions: Your payments to areas with less-developed banking infrastructure or complex regulations can take 5–7 days
2. Limited transparency: SWIFT GPI offers near real-time tracking for many payments, but full visibility still depends on the participating banks and the payment route
3. Currency conversion costs: When exchanging currencies, banks often add hidden markups to the rate

These issues affect you differently depending on your business model. If you run a retail business with tight cash flow, SWIFT's unpredictable timing can make inventory management challenging. For instance, you might face stockouts while waiting for your seasonal merchandise payment to clear.

If you're a small business making occasional international payments, you'll find the high fixed fees particularly burdensome. A $30 fee on a $500 payment means you're paying 6% just to send money.

For certain payment corridors, alternatives may offer faster settlement or lower fees. Multi-currency accounts let you hold foreign currency and skip conversion fees on recurring SWIFT transactions. Fintech payment platforms can provide faster settlement for specific country-to-country corridors.

Domestic alternatives like SEPA (for EUR transfers within Europe) or CHIPS and Fedwire (for USD within the US) bypass the SWIFT network entirely. These options generally lack SWIFT's global reach, but if you're running high-frequency payments on specific corridors, they're worth evaluating for speed and cost savings.

SWIFT payments and compliance

SWIFT's standardized messaging was designed with regulatory requirements built in. You benefit from this infrastructure every time you send or receive an international payment, even if you don't manage compliance screening directly.

Anti-money laundering and Know Your Customer requirements

SWIFT messages include structured fields for regulatory information: payment purpose, originator and beneficiary details, and source of funds. Banks use this data to screen transactions against anti-money laundering (AML) regulations before processing them.

When you initiate a SWIFT transfer to a new recipient for the first time, expect your bank to request Know Your Customer (KYC) documentation. This is standard practice and protects both parties. Common requirements include proof of business registration, the recipient's banking details, and documentation supporting the purpose of the payment.

Sanctions screening

Every SWIFT message passes through sanctions screening. Banks check sender and recipient details against sanctions lists maintained by the Office of Foreign Assets Control (OFAC) in the U.S., the EU, and other regulatory bodies.

This screening has real-world consequences. SWIFT disconnected sanctioned Iranian banks in 2012 following EU sanctions, and SWIFT disconnected Russian and Belarusian entities in 2022 following EU Council Regulations. If you're sending payments to sanctioned countries or entities, the transfer will be blocked. Your bank's compliance team handles this screening, but you should verify recipients independently before initiating high-value transfers.

SWIFT Customer Security Programme

SWIFT requires all member institutions to meet baseline security standards through its Customer Security Programme (CSP). The program includes mandatory security controls covering secure environment protection, access management, and threat detection.

For your business, this means your bank must attest annually to meeting these controls. CSP provides an additional layer of security beyond your own internal safeguards, helping protect the integrity of every SWIFT payment system transaction you send or receive.

The future of SWIFT

SWIFT is evolving to keep up with fintech competition and changing customer needs. SWIFT GPI (Global Payments Innovation) is its biggest upgrade, giving you near-real-time tracking, same-day settlement for many currency pairs, and clearer fee information.

GPI now covers the majority of cross-border payments on the network, with most payments credited to end beneficiaries within 24 hours. The Unique End-to-End Transaction Reference (UETR) enables tracking from originator to beneficiary in real time.

The SWIFT payment system is also undergoing its biggest structural change in decades: the migration to the ISO 20022 (MX) messaging standard. The November 2025 deadline for migrating cross-border payments has passed, bringing richer data in payment messages and more detailed remittance information. You'll see more complete transaction details and fewer manual reconciliation steps as a result.

SWIFT Go, launched for low-value cross-border payments (typically under $10,000), makes SWIFT more competitive for SMB payments that previously might have used fintech alternatives. If you're a small business sending regular payments under this threshold, SWIFT Go offers the network's security and reach at a lower cost.

The network is also adding API connections, cloud infrastructure, and AI to modernize its systems. For example:

• Fintech companies are connecting to SWIFT's APIs to give you a modern, reliable experience
• Trade finance operators are testing SWIFT's blockchain projects to digitize paperwork-heavy processes

If your organization relies heavily on older systems, you may face integration challenges. But if you can adapt, you'll gain advantages in speed, cost, and customer experience.
