F&O Ban List

The F&O Ban List is issued daily by the National Stock Exchange of India and temporarily restricts fresh derivative positions in stocks when their open interest reaches 95% of the market-wide position limit (MWPL).

During the ban period, traders can close existing positions, but new futures or options positions are not allowed until the stock is moved out of the ban list.

Why Do Stocks Enter The F&O Ban List?

A stock enters the F&O Ban List when derivative positions become too large compared to the exchange limit set for that stock. A stock enters the ban once open interest reaches 95% of its market-wide position limit, which is the maximum derivative exposure allowed for a stock, as determined by the NSE.

Open interest simply means the number of futures and options contracts that are still open. The market-wide position limit is the maximum exposure allowed in that stock, calculated from its free-float shares.

To check whether a stock may enter the ban list, the MWPL percentage is compared with the 95% threshold.

MWPL % = Open Interest ÷ MWPL × 100 Once this figure crosses 95%, fresh derivative positions are restricted.

What usually leads to a ban:

• Results, corporate announcements, or sector news often bring more futures and options activity into a stock.
• At times, speculative activity increases much faster than usual.
• Strong price movement often draws more traders into futures and options.
• A sudden rush to close earlier positions can also lift derivative activity quickly.

Rules For Traders During F&O Ban

Once a stock enters the F&O Ban List, derivative activity is allowed only within exchange restrictions.

What traders need to follow:

• Existing futures and options positions can be reduced or squared off.
• Fresh positions are not permitted until the stock exits the ban list.
• Intraday trades that increase open exposure are also restricted.
• Cash market trading continues as usual.
• If a trader increases an existing position or creates a new one during the ban, a penalty of 1% of the increased position value may apply, with a minimum charge of ₹5,000 and a maximum of ₹1,00,000.

When Does A Stock Exit The Ban List?

A stock comes out of the F&O Ban List once its market-wide position limit usage drops below 80%. In simple words, the number of active derivative contracts must reduce enough for the stock to move back within the exchange limit.

This usually happens when:

• Traders begin closing some of their existing futures and options positions.
• Speculative interest starts fading after the earlier build-up.
• Price movement slows, which often reduces fresh contract activity.
• As expiry approaches, overall open interest tends to decline.
