What is Peak Margin? Meaning, Example & Why It Matters
A rule requiring traders to hold sufficient margin at random intraday snapshots, not just at the end of the day.
Peak margin refers to SEBI's framework under which clearing corporations check margin requirements at several random points during the trading day, not only at the close. The highest margin required at any snapshot becomes your peak requirement for the day, and you must have that much margin available upfront.
Why Peak Margin matters to you
Before this rule, some brokers offered very high intraday leverage because margins were checked only at day end. Peak margin rules limited this, so intraday leverage is now much lower than it used to be. For traders, this means you need more capital to take the same intraday position.
If your available margin falls short of the peak requirement at any snapshot, the exchange may levy a penalty, which your broker typically passes on to you. This can happen even if you close the position later in the day, because the shortfall existed at the time of the snapshot.
Practical tip: ensure the full required margin is in your account before placing a trade, and remember that sale proceeds from delivery holdings may not be fully available as margin immediately. Check your broker's margin display before every leveraged trade.

Frequently asked questions
Why was peak margin introduced?
It was introduced to curb excessive intraday leverage and make sure positions are backed by adequate margin throughout the day.
Can I be penalised even if I closed my trade?
Yes, if your margin was short at the time of a snapshot, a penalty can apply even if you closed the position later.
Does peak margin affect delivery trades?
Delivery purchases need full payment, so peak margin mainly affects leveraged trades like intraday, futures and option selling.
