Global ACH payment

A global ACH payment system does not really exist. There is no comprehensive equivalent of the ACH system that is available worldwide.  Instead, similar electronic payment systems have been created in a number of countries, which are intended for payment transactions within those countries.  A few large international banks have created links between these systems, which simulate a global ACH system.  Under their systems, a company enters payment information, which the banks then reformat into the standard format of the country where the payment will be made.

Global ACH systems are by no means truly global.  National ACH systems have been built in much of Europe, North America, India, Singapore, Hong Kong, New Zealand, and Australia, and these systems can be linked into the ACH systems of other countries.  However, outside of these regions, wire transfers remain the most reliable method of funds transfer.
