Learn about intraday leverage rules (SEBI peak margin)

WHAT is this about?

WHY does SEBI care? Before 2020, brokers gave 20–40× intraday leverage. A ₹5,000 account could trade ₹2,00,000. One gap-down and the client owed money he never had — broker eats the loss or the market destabilises. SEBI's peak-margin regime (phased Dec 2020 → Sep 2021) forced upfront margin collection so risk matches capital.

HOW leverage is computed (from first principles)

Start with the definition of leverage as a ratio of exposure to your own money:

$\text{Leverage } L = \frac{\text{Position Value}}{\text{Own Margin}}$

The broker requires a margin percentage $m$ (fraction of position value you must put up). Your own money is then $m \times \text{Position Value}$ . Substitute:

$L = \frac{\text{Position Value}}{m \times \text{Position Value}} = \frac{1}{m}$

Margin has two parts (this is the heart of SEBI's rule):

$m = \underbrace{\text{VaR}}_{\text{Value-at-Risk}} + \underbrace{\text{ELM}}_{\text{Extreme Loss Margin}}$

VaR covers normal worst-case daily move (e.g. 99% confidence).
ELM is a buffer for extreme tail events (usually ~3–5%).

So the SEBI minimum upfront margin for equity intraday equals $\text{VaR}+\text{ELM}$ (often ~20% for liquid stocks), capping leverage at:

$L_{\max} = \frac{1}{\text{VaR}+\text{ELM}} \approx \frac{1}{0.20} = 5\times$

HOW "peak margin" actually bites

The clearing corporation takes 4 random snapshots of your positions during the day. For each snapshot it records the margin you should have. Your peak = the maximum of those.

$\text{Peak Margin} = \max\big(m_1,\, m_2,\, m_3,\, m_4\big)\times \text{Position Value at that snapshot}$

You must have collected 100% of the applicable margin upfront. Shortfall → penalty.

Recall Feynman: explain to a 12-year-old

Imagine renting a bicycle. You pay a small deposit (margin) so if you crash, the shop is covered. Leverage is like the shop letting you ride a bicycle worth way more than your deposit. But a strict inspector (SEBI) drops by at random times during the day and checks: "Is your deposit big enough for the bike you're riding right now?" You can't grab an expensive bike for one hour and swap it back before evening — the inspector might have already caught you. The biggest bike you were caught riding sets your required deposit: that's peak margin.

What is leverage in terms of position value and own margin?

L = \text{Position Value} / \text{Own Margin} = 1/m

Why did SEBI introduce peak margin rules?

To force upfront margin collection so client risk matches capital and prevent brokers giving excessive hidden intraday leverage.

What two components make up the upfront margin

m

VaR (Value-at-Risk) + ELM (Extreme Loss Margin).

How many random snapshots are taken during the day and what is peak margin?

4 random snapshots; peak margin = the maximum margin requirement observed across them.

If margin requirement is 20%, what is max intraday leverage?

1/0.20 = 5\times

Why can't squaring off before close save you from a shortfall penalty?

Because a random snapshot may have already recorded the higher requirement; peak margin is not end-of-day based.

What is the penalty for a first-time margin shortfall under ₹1 lakh?

0.5% of the shortfall per day.

What is a haircut on pledged securities?

A percentage reduction of a security's value before it counts as usable margin, larger for volatile stocks.

Hinglish (regional understanding)

Intuition Hinglish mein samjho

Dekho, leverage ka matlab hai chhote paise se bada position control karna. Agar aapke paas ₹20,000 hain aur broker aapko 5× leverage deta hai, to aap ₹1,00,000 ka trade kar sakte ho. Formula simple hai: $L = 1/m$ , jahan $m$ margin percentage hai. Yaani agar margin 20% hai, to leverage $1/0.20 = 5$ guna. Pehle brokers 20-40× tak de dete the, jisse chhote traders ek bade gap-down mein tabaah ho jaate the — isliye SEBI aaya.

Ab peak margin rule ka funda samjho. SEBI (clearing corporation) din mein 4 random time pe snapshot leta hai aapke position ka. In snapshots mein jo sabse zyada margin requirement nikalti hai — wahi aapka peak margin hai, aur utna margin aapke paas pehle se (upfront) hona chahiye. Purana jugaad — subah bada position lo, close se pehle square off kar do — ab nahi chalega, kyunki beech mein inspector (snapshot) aapko pakad lega.

Agar aapke paas required margin nahi hai to shortfall penalty lagti hai: pehli baar aur ₹1 lakh se kam shortfall pe 0.5% per day. Ek aur cheez: pledged shares ka pura value margin mein nahi ginta — uspe haircut lagta hai (jaise 20% haircut, to ₹1,00,000 ke shares se sirf ₹80,000 milega).

Yeh matter isliye karta hai kyunki intraday trading mein leverage sabse bada risk-multiplier hai. Samajh lo to profit bhi controlled, loss bhi controlled. Peak margin rule aapko discipline sikhata hai — apni capacity se zyada position mat lo, warna penalty bhi aur risk bhi.
