Pledging shares — using stocks as F&O margin

Instead of keeping cash idle for F&O margins, you can pledge your existing stocks and mutual funds. The catch: some brokers charge per pledge request, and the costs vary wildly.

What is pledging?

Pledging is the process of offering your demat holdings (stocks, ETFs, or mutual funds) as collateral margin for F&O trading. Instead of blocking ₹1,50,000 in cash for margin, you can pledge ₹2,00,000 worth of shares and get the equivalent margin (after a haircut of 10–50% depending on the stock).

Unpledging is the reverse — releasing your shares from collateral when you no longer need the margin. Both actions involve a depository transaction, which is why brokers charge for them.

Why pledge shares?

  • Capital efficiency: Your long-term holdings work double duty — earning returns while providing F&O margin.
  • Avoid interest costs: Without pledging, you'd either keep cash idle or use MTF (which charges 12–18% interest).
  • No selling required: You retain ownership of the shares. Dividends and corporate actions still apply to pledged holdings.

However, pledged shares get a haircut — the exchange doesn't give you 100% margin value. Blue chips like Reliance or HDFC Bank might get a 10–12.5% haircut, while volatile mid-caps could see 50% or more.

Cost comparison

  • Fyers: ₹5 per pledge request + ₹5 per unpledge request — one of the cheapest in the market.
  • INDmoney: Free — no charge for either pledge or unpledge transactions.
  • Zerodha: ₹35.40 per pledge request (₹30 + GST). Unpledge is free. If you pledge 5 different stocks, that's ₹177.
  • ICICI Direct: ₹29.50 per scrip per pledge request (₹25 + GST). Unpledge also charged.

These charges are per scrip, not per quantity. Pledging 1 share of Reliance costs the same as pledging 100 shares. This means it's more cost-effective to pledge fewer, higher-value stocks rather than many small holdings.

How pledging works step by step

  • Step 1: Select the stocks you want to pledge from your holdings in the broker's app or platform.
  • Step 2: Approve the pledge request via CDSL's TPIN or e-DIS authorisation (OTP-based).
  • Step 3: Margin is credited to your F&O account — usually within minutes, sometimes by next trading day.
  • Step 4: When you want to release the shares, initiate an unpledge request. The margin is debited and shares are freed.

Keep in mind that SEBI requires at least 50% of F&O margin to come from cash or cash equivalents (like liquid funds). Pledged shares alone won't cover 100% of your margin requirement.
