May 9, 2026

Sending money worldwide is a seemingly simple transaction, but it is supported by a highly sophisticated global infrastructure. Each transfer involves a complicated web of correspondent banks, messaging systems, compliance regimes, and liquidity arrangements.

If you are considering how to send money worldwide or seeking the best way to send money internationally, knowing how the backend works will help you make faster, cheaper and safer selections.

From SWIFT networks to blockchain innovation, this guide explains how international money transfer works and highlights new solutions such as TransFi. 

The Correspondent Banking System in Sending Money Internationally 

Correspondent banking networks underpin the traditional cross-border payment system. They enable banks to operate globally without a physical presence.

How it works:

  • There are only so many direct relationships your bank has overseas.
  • Depends on the partner banks (correspondent)
  • Money goes through many intermediaries

Example: 

When you send money from India to Brazil, your bank will send money via:

  • US Correspondent Bank
  • Another partner in Europe.
  • Finally got to the Brazilian bank.

Good to Know: Each middleman adds time, cost and potential opacity. 

What is a Nostro and a Vostro Account

These accounts are the liquidity backbone of international payments.

  • Nostro Account: “Our account with you” (held abroad)
  • Vostro Account: “Your account with us”

To speed up settlements, banks put money into these accounts in advance.

What is at stake: 

  • Currency conversion activated
  • Settlement delay cuts
  • Immobilises capital in foreign markets

The Role of Intermediary Banks in International Transfers 

Intermediary banks are needed, yet they are expensive.

Effect:

  • Add 1-2 day processing delays for each
  • Lower hidden fees
  • Decrease the final received amount 

Important: And that’s why we typically get less than we expect from users. 

SWIFT System: How to Send Money Internationally Using Banks 

What is a SWIFT?

SWIFT connects more than 11,000 institutions in over 200 countries.

It doesn’t transmit money, it sends instructions.
