Index derivatives now carry a higher minimum contract value, each exchange offers weekly expiry on only one benchmark index, option buyers must pay the premium upfront, and expiry-day margins are stricter. From 1 April 2026, STT rose to 0.05% on futures and 0.15% on options, which raises the cost of frequent trading.<\/p>\n<\/p><\/div>\n<p>The SEBI F&amp;O rules 2026 are not one single circular but a series of changes rolled out in phases, starting with the regulator&#8217;s October 2024 measures and continuing through the April 2026 tax change. Traders who last checked the F&amp;O rules a year ago may be working with outdated assumptions about contract size, expiry and costs.<\/p>\n<p>This guide collects the F&amp;O rules that matter for a retail trader, explains the purpose behind each, and shows how they change the cost and risk of trading index and stock derivatives.<\/p>\n<p style=\"margin-top:24px;\"><strong>Click Here &#8211; Get

Exchanges revise lot sizes at regular intervals so that contract value stays within the prescribed band as the index moves. Lot sizes therefore change over time, and the current number for <a href=\"https:\/\/univest.in\/indices\/nifty-50\/nifty-50-share-price-today\">Nifty 50<\/a> or <a href=\"https:\/\/univest.in\/indices\/nifty-bank\/nifty-bank-share-price-today\">Bank Nifty<\/a> contracts should always be checked on the exchange circular.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Weekly_Expiry_One_Index_Per_Exchange\"><\/span><strong>Weekly Expiry: One Index Per Exchange<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Before the change, several indices had weekly contracts, which attracted heavy retail activity on expiry days. Now each exchange can offer weekly expiry on one benchmark index. Other indices keep monthly contracts. Derivative expiries are also held on a fixed day, Tuesday or Thursday, so that expiries do not cluster on the same day of the week.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Upfront_Premium_and_Margin_Changes\"><\/span><strong>Upfront Premium and Margin Changes<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Option buyers now have to pay the full premium upfront instead of using broker-provided limits to buy options beyond their cash. Margin for short options on expiry day is higher, and calendar spreads no longer get a margin benefit on the day of expiry. For sellers this raises the capital needed to run short-dated strategies. These F&amp;O rules favour traders who plan margin in advance.<\/p>\n<p style=\"margin-top:24px;\"><strong>Use the Univest Screener to check live fundamentals before you act on any idea.<\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Position_Limits_and_Pre-Open_Session\"><\/span><strong>Position Limits and Pre-Open Session<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>SEBI introduced intraday monitoring of index option position limits, shifted to a delta-based measure of open interest for some limits, and added a pre-open session for the derivatives segment. The pre-open session lets orders be collected and matched before continuous trading starts, which is meant to reduce wide swings in the first minutes. These new F&amp;O rules also change how large positions are tracked.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_April_2026_STT_Hike\"><\/span><strong>The April 2026 STT Hike<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Alongside the SEBI derivatives rules, the Union Budget 2026-27 raised Securities Transaction Tax on derivatives from 1 April 2026.
