Automated Clearing House (ACH) is an electronic network for financial transactions in the United States. ACH processes large volumes of credit and debit transactions in batches.
Is there ACH analogue in Asia?
ACH as offered in US is a very broad and versatile network used for a range of business case. There is no other network as versatile. In Europe UK has BACS as equivalent about 50-70% of what US-ACH offers. Most European countries also have ACH [Collectively Called ACH, have 90% of the layouts that are identical, called by different names domestically, different business capabilities and rules].
Most countries in Asia also have similar networks. For example in India there is ECS now replaced by NACH. In Singapore/Indonesia/Thailand/Malaysia they have Giro's. China has CNAPS and BEPS.
So essentially every country has addressed the business need differently and bis.org has a decent over-view country wise on the clearing systems available.
