On June 28, 2023, L&T Finance Holdings (L&TFH) and Manappuram Finance stocks were placed under the F&O ban. However, they were still available for trading in the cash market. The ban is imposed when the open interest on a stock exceeds 95% of the market-wide position limits, and is lifted when the open interest falls below 80%. These bans do not affect traders who trade in indices. The stocks were banned due to their high open interest, with L&TFH experiencing a significant increase from the previous session.
