Margins & Margin penalties when trading with leverage

September 28, 2022


When an equity or F&O trader takes a position greater in value than the funds or margins available in their account, such positions are said to be leveraged. This is typically done with the idea of generating a higher return on capital, but it entails taking a higher risk. Leveraged trades also give the ability to take a short view of a stock or the market, i.e., to profit from a trading idea that predicts stock prices going down. Using F&O, a trader using leverage can also hope to generate returns by predicting volatility, arbitraging, and employing more such strategies. F&O is also used to hedge either a single stock or an entire portfolio. In the case of F&O, leverage is baked into the product, unlike in equity.

Here are some examples of how leverage lowers the fund requirement to enter certain trades.

  • A short intraday trade of 100 shares of stock X trading at Rs.1000 with a 5X leverage (~20% margin requirement) would mean that one needs to have only Rs.20,000 margin to short the stock worth Rs.1,00,000.
  • To buy one lot of Nifty futures (lot size 50) trading at 17000, one would only need to have roughly 12% of the contract value, which equates to Rs.1,02,000 (contract value calculated as 17000*50 = 8,50,000). Since leverage is baked into the F&O contract, it is not possible to pay the entire contract value of Rs.8,50,000 and trade without leverage, unlike in equity, where one can pay in full for the purchased shares.
  • Margins required for writing (shorting) options, similar to futures, is only a percentage of the actual contract value.
  • When buying options, unlike in intraday stock, futures, or short options where the maximum loss is potentially unlimited, the loss is limited to the premium paid. So, while option buying seems to be a non-leveraged trade, technically, it is the riskiest and most leveraged product.Let me explain. To buy one lot of Nifty 17000 calls at Rs 100, the premium required is Rs 5000 (50 × 100). But, by paying Rs 5000, the exposure from the position is 17000 × 50 = Rs 8,50,000, i.e. leverage of 170 times! While Rs 5000 is the maximum loss, how fast you can lose this money can be determined by the contract exposure value of Rs 8.5lks. That is quite fast!

Leveraged trades contribute to over 90% of exchange trading volumes, but most of these volumes are from just about ~15% of active traders. Leveraged trades provide significant liquidity, cushioning volatility during events, and significantly help reduce impact costs for investors.


With a leveraged trade (apart from option buying), since the exposure is larger than the funds available in a trader’s account, a trader can technically lose more money than the funds available in the account. So, in the above example, if a trader bought 100 shares of stock X at Rs 1000 with only Rs 20,000 in the account, and if the stock price suddenly drops from Rs 1000 to Rs 500 for any reason, the trader would lose Rs 50,000. This additional Rs 30,000 loss beyond the Rs 20,000 available with the trader is the liability of the brokerage firm to settle.

If tens of thousands of customers lost money on the same stock, a brokerage firm that is not well capitalised could potentially go bankrupt if they’re unable to recover the debits from clients, thereby risking not just other customers, but the entire market. As you can imagine, the higher the leverage, the higher the risk. Not just for the trader, but to the brokerage firm and in turn, the overall markets.

To keep this risk in check, regulators require brokerage firms to collect a minimum margin for all leveraged trades. This minimum margin is called VAR+ELM (Extreme Loss Margin) for equity and SPAN+Exposure for F&O. Until last year, brokerage firms had the flexibility to give additional leverage over and above the minimum for intraday trades. This was a selling point for many firms. This is no longer possible after the introduction of peak margin regulations and today, margin requirements are uniform across the industry.

Using our margin calculator, you can check the minimum margin requirements or leverage across equity, currency, & commodities while trading with us. You can read this post to learn more about how margin requirements have changed historically.

Margin penalty

Margin penalty is a way for regulators to ensure that minimum margins are collected. Until last year, the minimum margin requirement was only on an end-of-day (EOD) position. This meant that for any open position, there had to be that minimum margin available in the trading account at the end of the trading day. The exchanges didn’t track margin requirements intraday. They charged a penalty if the required margins were not made available at the end of the trading day. After the introduction of peak margin checks that happen intraday, the penalty is also applicable for intraday margin shortfalls on positions.

The clearing corporation (CC) takes five random snapshots of all intraday positions and margins across customers during the day to determine whether a sufficient margin is available during those snapshots. If sufficient margins aren’t available either at the end of the trading day or in the intraday snapshots, a margin penalty is charged on the net shortfall amount. The penalty is 0.5% of the shortfall amount lower than Rs 1L, and 1% for higher than Rs 1L. This can go up to 5% in the case of shortfall for more than three instances in a month. These penalties are collected by exchanges and deposited in the core Settlement Guarantee Fund (core SGF).

Speaking of margin penalties, they are of two types.

Upfront margin penalty

This is applied if there isn’t sufficient margin in a trader’s account at the time of entering a trade. For example, if a trader had Rs 1L in the account and the brokerage firm allowed the customer to enter a position with a minimum margin (SPAN +Exposure) of Rs 1.1L, this would mean a shortfall of Rs 10,000, resulting in a penalty on the shortfall amount.

Non-upfront margin penalty

Theoretically, a non-upfront margin includes all such margins that need to be collected after the client enters a trade (after fulfilling the upfront margin requirement). When the client does not fund such additional margin requirements on time, it leads to a shortfall where a penalty may be charged. For example, if there are marked-to-market (MTM) losses in a futures contract, there is time until T+1 day to add the funds, failing which, it is considered a non-upfront margin shortfall and a penalty is applied. Similarly, when exchanges add ad-hoc margin requirements owing to volatility or physical delivery margins to stock F&O contracts on the last week of expiry, they are considered non-upfront margins.

Here are more detailed examples of upfront and non-upfront margin penalties.

Who bears the margin penalty?

A broker should bear the penalty if they allow a customer to trade without sufficient upfront margins. It should be on the customer if the customer doesn’t bring in additional margin requirements after taking a trade. In the same spirit, regulations state that an upfront margin penalty can’t be passed on to the customer by the broker, and that non-upfront can be passed.

This is where it gets tricky, especially in derivatives (F&O, CDS, MCX). After the introduction of the peak margin penalty last year, there are certain situations where even if the broker collects sufficient upfront margin while entering a trade, if margins go up after entering a position due to unpredictable market conditions, that resulting shortfall is also considered an upfront margin shortfall, putting the obligation on the broker.

For example, if a customer holds a Buy Nifty futures and a Buy Nifty put position, the margin required is only ~Rs 25k as the put limits the risk of the futures position. If the put position is closed, the margin for futures goes back up to Rs 1lk. If the customer now doesn’t have sufficient margins (Rs 1L), it is considered an upfront margin violation. Similarly, suppose the margin required for the F&O portfolio of a customer goes up by the end of the day; even if the broker had ensured sufficient margins pre-trade, it is still considered an upfront margin shortfall. When you short options, there is no concept of marked-to-market losses that need to be funded by the next day, like in futures. When a short option loses money, the margin required goes up, which, again, is considered an upfront margin penalty.

In the above cases, most brokers had taken a stance that since they ensured that sufficient pre-trade margins were available, any penalty on shortfalls owing to unpredictable market volatility or any other reason after taking a position is not an upfront margin penalty but non-upfront, which can be passed on to the customer who took the position. Typically in these scenarios, customers are alerted of the margin shortfall and requested to add funds or close certain positions to cover the shortfall.

However, the stock exchanges recently published a circular stating that these scenarios should be considered cases of upfront margin penalties and that the broker shouldn’t pass them to customers. Brokers have been asked to refund all such upfront margin penalties collected from October 2021 (when peak margin penalties started) to customers.

Brokers and broker associations have been consulting with the exchanges and SEBI to understand why these scenarios, where margin requirement changes post-trade owing to unpredictable market conditions, are considered as upfront margin shortfalls as it is also impossible for brokers to ensure compliance in these scenarios. Only customers who are in control of their positions, can. SEBI identified one such anomaly and corrected it to an extent by issuing a new circular applicable from August 2022 that doesn’t consider any intraday margin increase for peak margin penalty calculations. However, this doesn’t cover all the scenarios described earlier.

Following the latest update to the regulation, Zerodha has stopped passing any such post-trade upfront margin penalties from Aug 2022 to customers. We have also been computing and refunding any upfront margin penalties from October 2021 that were passed on to customers. If you believe you haven’t received a refund for such a case, you can create a ticket here. Only upfront margin penalties (and not non-upfront) will be refunded.

In my view, which may be biased because I am the CEO of a brokerage firm, that brokers have to bear these penalties even after ensuring sufficient pre-trade margin availability in accordance with regulations, is unfortunate. This is despite having mechanisms to alert customers on intraday shortfalls owing to unpredictable market conditions. We are building a function in our risk management system (RMS) that will not allow exiting any position if the post-exit margin goes up and the funds available aren’t sufficient for the new margins. We are also working on squaring off positions as soon as possible when the margin increases and if there are no free funds. While the change in RMS is a complex technological problem, squaring off positions instantly without giving sufficient time for the customers is bound to create its own set of issues.

Ideally, if the margin goes up on the F&O portfolio either due to volatility or in the case of option writing due to position moving against the customer, there should be time provided till T+1 day to bring in additional margins. This is like in Futures, where there is time till T+1 to transfer any marked-to-market losses. In cases where exiting positions increase margins, it should be treated as a non-upfront margin penalty, and the onus should be on the customer to comply with the regulation.

Hopefully, this post helps you understand how margins and margin penalties work when trading with leverage on Indian exchanges.

    Thanks Nithin for taking the time to explain this in detail. I have been always confused on this topic.

  2. Rohan Gupta says:

    Thanks Nithin for the detailed clarification – it is due to your transparency and honesty that we have massive faith and respect for Zerodha as a customer. I have raised a case in your support section for the refund of the penalty 2 weeks back – however, it still shows as “resolution pending”. Is there a timeline for processing the refund pls.

    • Shruthi R says:

      Hey Rohan, we are in the process of calculating and refunding the upfront margin penalties. Please allow us a few days, you’ll have an update on your ticket once the refund is processed. Thank you for your patience.

  3. P C Karanth says:

    Sane explanation to an insane regulation

  4. Govindan VK says:

    Thanks for providing clarity in upftont nonUpfront margin pensltied. It is reasonable that post entry peak-margin penalty be passed to the customer after giving sufficient time to clear the shortfall like the case of futures.
    -A customer

  5. Rohit says:

    If broker does not send any intimation or ask for additional margin about your peak margin increase during the day ..can broker charge penalty?

    • Navana says:

      Whether or not they send notifications, according to the circular they are not supposed to pass on the penalty to the customers. The ideal scenario would be to pass on these penalties only if the brokers have notified their clients and the clients have not brought in sufficient margins. SEBI should work on that. Passing on penalties to the broker after clients have entered positions in the garb of “upfront margin penalty” is a systemic risk.

    Can I check if a margin penalty was charged when I go to my P&L in zerodha console. I mean a consolidated amount because you don’t want to pass the headache of margin calculation going through multiple statements on your clients.

  9. Suvajit says:

    Thank you for the transparency. As always I have full faith that you guys will never ever do anything illegal, whatever be the amount.

    I have a question please, How do I know how much I was charged and where can I see the refund status? Any help would be really appreciated.

  13. Abhishek Savalia says:

    Hi Nithin, in case of margin increased beyond available free fund after entering into options trade, there should be some time available to the person before it is considered for non upfront margin penalty so funds can be added.

    Retailers dont know about complexity of margin required after entering trades so its unfair to consider it for non upfront margin penalty.

    Either you collect more margin upfront to tackle this or regulator should allow some time (t+1) to add fund if they are going to consider it for non upfront margin penalty.


  14. Asif says:

    Thanks for bringing much-needed clarity on this subject. I really appreciate the transparency as it helps in keeping confidence in Zerodha.

    I was sceptical about this penalty since the beginning and have raised it with Zerodha’s support earlier through mail communication back and forth. Finally, I lost hope and end up losing almost 2Lakhs. I hope, I get my hard-earned money refunded due to this faulty implemented penalty with good intentions but improper execution.

  19. Naveen says:

    Hi, will short-margin penalty comes under upfront margin penalty?

    • Shubham says:

      Hey Naveen, the short margin penalty posted on your ledger on Console, will include both upfront and non-upfront margin penalties. We’ve been refunding any upfront margin penalties collected from Oct 2021. If you haven’t gotten a refund for any reason, please create a ticket here.

    • Venkat says:

      I also have same question. My statement indicates 4-5 entries since October 2021 – NSE F&O short-margin penalty for date …

      • Shubham says:

        Hey Venkat, we’ve been refunding any upfront margin penalties collected from Oct 2021. If you haven’t gotten a refund for any reason, please create a ticket here.

  20. Vishal Kotecha says:

    The short collection of upfront margin penalty is charged to the TM and not the the end client

    It is the responsibility of the TM to inform the margin shortfall, just how the MTM loss is informed by means of Margin Statement mandated to be sent to the client on T day itself (which Zerodha never do), and give them an opportunity to replenish it by T+1 day. But TM didn’t establish any such mechanism to inform the shortfall and continued to pass the penalty levied on them to its client.

    And most importantly,

    Why NSE is favoring the broker by asking them to refund such penalty charges if charged only after Oct 11, 2021 and not from the time it came into effect which is July 31, 2020?
    Why NSE is asking the investor/trader community to pay for the penalty levied on the broker?

    NSE/INSP/45191 – July 31, 2020
    “Member cannot pass on the penalty w.r.t. short collection of upfront margin to client.”

    NSE/INSP/49929 – Oct 12, 2021
    “This has reference to Exchange Circular NSE/INSP/45191 dated July 31, 2020 with respect to “Guidelines/clarifications on Margin collection & reporting” wherein it was clarified that the members cannot pass on the penalty w.r.t short collection of upfront margin to client. However, Exchange has observed that certain members are passing on the penalty levied by clearing corporations on account of “short/non-collection of upfront margins from clients” to respective clients.

    In view of the above, it is reiterated that members are not permitted to pass on the penalty levied by clearing corporations on account of “short/non-collection of upfront margins” to clients under any circumstances.”

    NSE/INSP/53525 – Sept 02, 2022
    “This has reference to Exchange circular NSE/INSP/45191 dated July 31, 2020 wherein it was clarified that the members cannot pass on the penalty w.r.t short collection of upfront margin to client. Further, it has been reiterated again vide Exchange circular SE/INSP/49929 dated October 12, 2021 that members are not permitted to pass on the penalty levied by clearing corporations on account of “short/non-collection of upfront margins” to clients under any circumstances.”

    “Members are advised to refund the penalty levied by clearing corporations on account of “short/non-collection of upfront margins” to the clients on an immediate basis if same has been passed on to the clients after 11th October, 2021.”

    thanks for sharing greatful information about the leverage .

  22. Amol says:

    Call back

  23. Anji says:

    Hi Nithin,

    After entering into the trade my trading account shows more than 50k balance. But after market hours its saying again margin short fall . Why its not showing at the time of entering into trade. suddenly why its increasing the margin requirement after market hours.

  24. Amit Kale says:

    Hi Nithin,
    Why brokerages like you don’t try to discuss with sebi about the huge margins blocked while shorting options? That will easily solve the problem. For example – more than 100000 INR margin is blocked if I short 2 lots of Nifty call or put. So how much is the maximum loss I will incur in a day even if Nifty falls or goes up by 1000 points? It’s around 100000 INR. So this kind of unrealistic scenario also is taken care of by the 100000 INR margin blocked at the time of shorting. So asking clients to bring in more funds when margins are already so high is ridiculous. Margin shortfall should be triggered only if the remaining margin after the notional loss is less than say 20 percent in my opinion

    Thanks in advance for sharing your thoughts on this

    Amit Kale
