Glossary of Payment Methods

UK Payment & Banking Market

The UK has a robust payments infrastructure with several key systems, each with its own limitations.

Europe (EU) Payment & Banking Market

The EU operates under a harmonized payment framework called SEPA to facilitate cross-border transactions.

US Payment Market

For comparison, here are two key US payment systems.

  • ACH (Automated Clearing House): The US network for electronic bank-to-bank payments. ACH payments are processed in batches and are not instant. Nacha, the organization that oversees the network, has raised the limit for Same-Day ACH to $1 million. However, individual banks often set their own, lower limits.
  • FedNow: A new instant payment infrastructure from the Federal Reserve. The transaction limit for FedNow has been increased from the default of $100,000 to $1 million. Financial institutions can choose to use this higher limit.

What is SWIFT?

SWIFT is a global messaging network used by banks and financial institutions to securely exchange information about cross-border payments, securities, and financial transactions. It does not move money itself, but instead provides the standardized communication layer that enables international transfers.

How Does SWIFT Work?

  1. A bank sends a payment instruction (e.g., from London to New York).
  2. SWIFT transmits the message in a standardized format to the receiving bank.
  3. The funds are settled through correspondent banks or central bank networks.

This process ensures accuracy, security, and interoperability across thousands of banks worldwide.

Key Features of SWIFT

  • Global Reach: Used by more than 11,000 institutions in over 200 countries.
  • Standardization: Every message follows ISO 20022 (gradually replacing MT formats).
  • Security: Encrypted messaging and strict governance ensure reliability.
  • Flexibility: Supports payments, securities trades, FX confirmations, and more.

SWIFT vs SEPA / Faster Payments

  • SWIFT = International, cross-border, typically slower and more expensive.
  • SEPA / Faster Payments = Domestic/regional schemes (EU or UK) offering faster, cheaper payments.

Limitations of SWIFT

  • Costly: Fees often range between $10–50 per transfer.
  • Slow: Transfers can take 1–5 business days.
  • Reliance on Intermediaries: Multiple correspondent banks can delay settlement.

Why SWIFT Matters in the UK & EU

Despite new alternatives like SEPA Instant, Faster Payments, and even blockchain rails, SWIFT remains the backbone for global B2B and cross-border transactions.
For regulated entities (EMIs, PSPs, banks), SWIFT membership or access via a partner bank is essential for offering full international money transfer services.
