NSE Broker Inspection Lapses: Margin Trading, Client Funds and Cyber Gaps Flagged (October 29)

NSE broker inspection lapses are back in the spotlight. In a circular dated October 28, the National Stock Exchange listed the common violations it found while inspecting trading members and their authorised persons (APs, the sub-brokers who sit between a broker and its clients) over the half year from October 2025 to March 2026. The list, published as NSE circular NSE/INSP/77149, reads like a checklist of what can go wrong with your money once it leaves your bank account. Business Standard reported on the findings on October 29.

NSE broker inspection lapses in margin trading

The headline item is the margin trading facility, or MTF, where a broker funds part of a client’s stock purchase. The rules say the client’s margin has to come as cash, cash equivalents or Group I equity shares, with an appropriate haircut. NSE found brokers who hadn’t collected adequate margins in that form. It also found brokers who gave MTF on securities outside Group I, which aren’t eligible for the facility at all.

That matters more than it sounds. Leverage on weaker stocks with thin margins is exactly the mix that turns a bad day into a forced sell-off in a client’s account.

Client money and settlement

The second cluster is about client funds. The exchange flagged brokers that paid out more to clients than their available credit balances, didn’t settle client funds, sent daily margin statements late or with wrong details, and misreported margin and mark-to-market loss collections to the exchange. Some passed on to clients the penalty for short collection of upfront margin, a cost the circular lists as a violation. Others didn’t upstream clients’ clear credit balances to the clearing corporation within the set timelines, or invoked client securities beyond what the client actually owed.

NSE also noted fully paid-up securities being pledged in the client unpaid securities pledgee account (CUSPA). If you paid in full, your shares have no business being there.

What the APs were doing

The AP section is the most uncomfortable read. NSE found APs receiving or paying funds to clients, taking clients’ user IDs and passwords to trade on their behalf, and trading in client accounts with a focus on generating brokerage. Some were offering fixed or assured returns, profit-sharing, account handling and unauthorised PMS. In some cases the AP’s terminals weren’t found at the location reported to the exchange.

Elsewhere in the books of brokers, the list includes trading allowed in a minor’s account, no surveillance of client trading, delayed contract notes and incorrect data under risk-based supervision and in annual returns.

Cybersecurity gaps

On the tech side, the exchange cited two-factor authentication that wasn’t enabled, or was enabled but not validated, on important systems; weak password policies; generic IDs with privileged access and no clear owner; data at rest that wasn’t encrypted; and no web application firewall protecting internet-facing infrastructure.

What it means for investors

This is the exchange’s half-yearly list, following earlier circulars dated December 19, 2024 and March 27, 2026, and it names no broker. The circular simply asks members to put systems in place to strengthen compliance. But we’d treat it as a useful prompt. Never share your login with anyone, including your AP. Check your daily margin statements and the retention statement after each running-account settlement. Walk away from anyone promising fixed returns on equity trading. And if you use MTF, ask what you’re pledging and on which stocks.
