NACH
Also written National Automated Clearing House
National Automated Clearing House — NPCI's centralised electronic clearing system for repetitive payments, which replaced ECS and now carries SIP debits and dividend and redemption credits.
In plain language
A monthly SIP, an EMI or an electricity bill needs the same thing: an instruction to move the same kind of money, again and again, without anyone signing a cheque each time.
National Automated Clearing House (NACH) is the system that does it. The workbook: it is a centralised clearing system launched by the National Payments Corporation of India (NPCI) that aims to replace and consolidate multiple existing Electronic Clearing Service (ECS) systems across India and create a faster, more efficient platform.
It is built for interbank, high volume, electronic transactions which are repetitive and periodic in nature.
How it works
The system (Chapter 9).
| Feature | Detail |
|---|---|
| Launched by | NPCI |
| Replaced | ECS for repetitive payments; existing ECS mandates moved to NACH with participating banks, with no investor intervention needed |
| Speed | Same day presentation and settlement, including returns processing |
| Facilities | Standardisation and digitisation of mandates, simplification, lower operational cost, shorter activation time |
| Variants | NACH Credit and NACH Debit |
| Coverage | Active in all Indian banks with core banking |
| Typical uses | Debits for bills, loan instalments, insurance premiums, SIPs; bulk credits such as dividends, salaries, interest, pensions |
Where a mutual fund investor meets it.
- Money in. SIPs can be paid by post-dated cheques, NACH or standing instructions — cash is not an accepted mode. The SIP enrolment form names the bank account registered for NACH, direct debit or SI.
- One-Time Mandate. An OTM authorises the bank to process debits raised by a specified mutual fund; the debits happen through NACH. Registering an OTM can take 3 to 4 weeks.
- Money out. Dividends and redemption proceeds are credited through electronic modes such as direct credit, NEFT and NACH.
A wording inconsistency. Chapter 9.8 says NACH was launched by NPCI, but the SIP section later refers to "the NACH facility of the RBI", requiring an account in a city where RBI has approved the facility and a bank participating in local MICR clearing. If a question turns on who launched NACH, the answer supported by the system description in 9.8 is NPCI.
A worked example
Ravi, in Bhopal, wants a Rs 5,000 monthly SIP. Timings are from the workbook's own illustration; amounts are illustrative.
Without an existing mandate. His fund requires 30 days to register an SIP. He submits the enrolment form on 5 September and chooses the 15th as his SIP date. The 15 September instalment is too soon, so the first instalment is 15 October. From then on NACH debits Rs 5,000 from his account each month — Rs 60,000 a year — with same-day presentation and settlement.
With a One-Time Mandate already registered. The workbook notes that the enrolment time may come down when an OTM is already registered in the folio. Ravi can then start further SIPs, or lump-sum purchases, in that folio without a new bank authorisation each time.
On the way out. Three years later Ravi redeems Rs 2,40,000. The proceeds come back to his registered bank account through an electronic mode such as NACH or NEFT — no cheque to deposit.
What he cannot do. Pay an instalment in cash. The Chapter 9 sample question lists cash as the mode not accepted for SIP instalments, against post-dated cheques, NACH and standing instructions.
Why NISM asks about it
Chapter 9.8 describes NACH among the payment modes, and Chapter 9.11–9.12 use it for SIPs and One-Time Mandates. The Chapter 9 sample question on SIP payment modes (cash is not accepted; NACH is) is the direct test. Also expect: NPCI launched it, it replaced ECS, it offers same day presentation and settlement, and it comes as NACH Credit and NACH Debit.
Common exam traps
- NACH was launched by NPCI, not by SEBI, AMFI or the registrars. (The workbook's later "NACH facility of the RBI" phrase is the inconsistency.)
- NACH replaced ECS, and existing ECS mandates were migrated without the investor having to do anything.
- Same day presentation and settlement — not T+1.
- Two variants: NACH Credit and NACH Debit. A SIP uses a debit; a dividend or redemption payout is a credit.
- An OTM is not a separate payment system — its debits run through NACH.
- Cash is not an accepted SIP payment mode.
