USCNBA
Also written Up Streaming Client Nodal Bank Account
The bank account in which a stock broker or clearing member must receive all client funds, named "Name of the SB/CM – USCNB account" under SEBI's standardised bank account nomenclature.
In plain language
A broker needs somewhere to receive money from its clients. SEBI does not leave the naming of that account to the broker's own preference — it has to follow a fixed pattern, so that a bank, an auditor, or the exchange can immediately recognise what the account is for.
The Up Streaming Client Nodal Bank Account, or USCNBA, is that receiving account. Every rupee a broker or clearing member takes in from a client is meant to land here.
How it works
The workbook (Chapter 6, section 6.3.1) explains that SEBI, by circular dated 13 December 2023, advised changing the nomenclature of stock broker client bank accounts to one of two categories. The USCNBA is the receiving side: "Stock Brokers/Clearing Members shall receive clients' funds in USCNBA," and the required naming convention is "Name of the SB/CM – USCNB account."
The USCNBA connects directly to the upstreaming framework and to running-account settlement safeguards: funds received from clients whose running account has already been settled must remain in the USCNBA and must not be used to settle another client's running account. Exchanges are required to build a monitoring mechanism to police exactly this.
A worked example
A brokerage named Kaveri Securities Pvt Ltd must, under SEBI's nomenclature circular, title its client-receiving account "Kaveri Securities Pvt Ltd – USCNB account."
When client Ramesh Iyer transfers Rs 3,50,000 into the brokerage to fund a purchase, that money is received into this USCNBA — not into the broker's general corporate account, and not directly into the settlement account.
Suppose Ramesh's running account is settled on the first Friday of the month, and a separate client, whose running account was settled a week earlier, sends in a fresh Rs 1,00,000 the next day. Under the rule, that Rs 1,00,000 must stay in the USCNBA and cannot be dipped into to help settle Ramesh's running account balance — even temporarily, and even if the broker intended to reimburse it later.
Why NISM asks about it
Chapter 6 (section 6.3.1, Mode of Payment) introduces USCNBA alongside its counterpart, DSCNBA, as the two-account structure SEBI mandated for client bank accounts. Expect the naming convention and the direction of fund flow — funds come in through the USCNBA — tested directly, and possibly paired with a question on why funds cannot cross between clients through it.
Common exam traps
- USCNBA is for receiving funds FROM clients — payments TO clients go through the separate DSCNBA, not this account.
- The naming format is fixed: "Name of the SB/CM – USCNB account" — a broker cannot use its own naming scheme.
- Funds from a client whose running account is already settled must stay in the USCNBA and cannot fund another client's settlement, even briefly.
- Do not confuse USCNBA with the separate "Name of Stock Broker – Settlement Account", which is the account used specifically for settlement obligations with the clearing corporation.

1.Under SEBI's December 13, 2023 circular on client bank accounts, from which account must a stock broker make payments to clients?
- a)The Down Streaming Client Nodal Bank Account (DSCNBA)
- b)The Up Streaming Client Nodal Bank Account (USCNBA)
- c)The account named 'Name of Stock Broker - Settlement Account'
- d)The primary clearing account with the designated clearing bank
Show the answer
Answer: (a) The Down Streaming Client Nodal Bank Account (DSCNBA)
SEBI renamed the client bank accounts into two categories:
- “Up Streaming Client Nodal Bank Account (USCNBA): Stock Brokers/Clearing Members shall receive clients’ funds in USCNBA.” Nomenclature “Name of the SB/CM –USCNB account”.
- “Down Streaming Client Nodal Bank Account (DSCNBA): Payment to clients shall be made only from DSCNBA.” Nomenclature “Name of the SB/CM –DSCNB account”.
Memory hook: money comes up from clients, and flows down to clients.
Why the others are wrong:
- USCNBA — that is for receiving client funds, not paying them.
- Settlement Account — “Bank account(s) held for the purpose of settlement shall be named 'Name of Stock Broker - Settlement Account'”; it is for settlement, not client payments.
- Primary clearing account — used for settlement with the clearing corporation, and withdrawals from it are only in self-name.
