Weekly Expiry on WebNotes

How the F&O expiry calendar works

Sun, 21 Jun 2026 00:00:00 +0000

The F&O expiry calendar in India runs on a fixed weekday rule set by the Securities and Exchange Board of India rather than on a list you memorise. Every derivative on the National Stock Exchange expires on a Tuesday and every derivative on the Bombay Stock Exchange expires on a Thursday, a split that took effect on 1 September 2025 under the SEBI circular dated 26 May 2025. Learn the rule and you can place any contract on a calendar without looking up a date.

Nifty weekly expiry on Zerodha

Sun, 21 Jun 2026 00:00:00 +0000

Nifty 50 weekly options are the National Stock Exchange surviving weekly benchmark, the single weekly index contract the NSE is permitted to run under the Securities and Exchange Board of India one-weekly-per-exchange rule of November 2024. They are options on the Nifty 50 , the NSE 50-stock benchmark, expiring every Tuesday since 1 September 2025, cash-settled, and the most actively traded index option in India, listed on Zerodha in the NSE F&O segment on Kite .

Sensex weekly expiry on Zerodha

Sun, 21 Jun 2026 00:00:00 +0000

Sensex weekly options are the Bombay Stock Exchange surviving weekly index benchmark, the single weekly index contract the BSE is permitted to run under the Securities and Exchange Board of India one-weekly-per-exchange rule of November 2024. They are options on the Sensex , the BSE 30-stock benchmark, expiring every Thursday since 1 September 2025, cash-settled, and listed on Zerodha in the BSE F&O segment on Kite .

When SEBI restricted each exchange to one weekly index expiry, the BSE chose the Sensex over its Bankex contract, mirroring the NSE’s choice of Nifty 50 over Bank Nifty. The Sensex weekly then moved from its old Friday slot to Thursday in the September 2025 weekday standardisation. This article sets out the expiry day, the lot size and how it was raised, the cash settlement, and how Zerodha lists and charges the contract.

The phaseout of Bank Nifty weekly options

Sun, 21 Jun 2026 00:00:00 +0000

The phaseout of Bank Nifty weekly options removed the most heavily traded short-dated index option in India from the National Stock Exchange on 20 November 2024. It was a direct consequence of the Securities and Exchange Board of India rule, in the October 2024 derivatives framework, that each exchange may run only one weekly index option. The NSE could keep one, and it kept the broader Nifty 50 over Bank Nifty , so the Bank Nifty weekly was discontinued while its monthly options and futures continued to trade.

Weekly currency options on Zerodha

Sun, 21 Jun 2026 00:00:00 +0000

Weekly currency options are short-dated, exchange-traded options on the USD/INR rate that expire each Friday, listed on the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE) under the joint oversight of SEBI and the Reserve Bank of India . They are European-style, cash settled in rupees against the RBI reference rate, and carry a lot of USD 1,000. Zerodha lists them on Kite once the currency derivatives segment is active, alongside the monthly options and the USDINR futures.

Weekly versus monthly expiry

Sun, 21 Jun 2026 00:00:00 +0000

Weekly and monthly expiry are the two tenors in which Indian exchange-traded options trade, distinguished by how often a contract expires and, since the 2024 to 2025 reforms, by how few instruments carry a weekly. After the Securities and Exchange Board of India restricted weekly options to one index per exchange in November 2024, only the Nifty 50 on the National Stock Exchange and the Sensex on the Bombay Stock Exchange have a weekly contract, while every single-stock option trades in a monthly tenor only.

SEBI F&O entry barrier rules (October 2024 framework)

Mon, 18 May 2026 00:00:00 +0000

The SEBI F&O entry barrier rules announced on 1 October 2024 are the most consequential tightening of retail access to Indian derivatives in a decade. The framework, set out in a SEBI circular dated 1 October 2024 and operationalised through subsequent exchange-level implementation circulars, comprises six measures that collectively raise the minimum capital required to participate in index futures and options, reduce the volume of weekly expiry contracts, and tighten intra-day risk parameters around expiry. The framework was a direct policy response to a SEBI study published in September 2024 that found 93 per cent of retail individual traders in equity F&O lost money over the three financial years FY22 to FY24, with aggregate net losses of approximately Rs 1.81 lakh crore.

Weekly expiry contraction (November 2024)

Mon, 18 May 2026 00:00:00 +0000

The weekly expiry contraction of November 2024 collapsed the Indian weekly options expiry calendar from five distinct weeklies across two exchanges down to two. The change was one of the six measures in the SEBI F&O entry barrier rules 2024 framework dated 1 October 2024 and became operative from 20 November 2024 with the cutover handled by NSE and BSE through staged delistings of the affected contracts.

Before November 2024, Indian retail option traders had access to five weekly expiries across the trading week: Tuesday for Nifty Financial Services, Wednesday for Nifty Midcap Select and BSE Bankex, Thursday for Bank Nifty and Nifty 50 , and Friday for Sensex . The five expiries collectively dominated retail F&O turnover, with weekly contracts contributing approximately 70 to 80 per cent of total index options volume on most trading days in 2023 and the first three quarters of 2024. The variety enabled retail traders to deploy strategies that operated daily on a different weekly contract, with the proximity to expiry generating the high theta-decay and gamma-risk profile that retail option sellers and short-dated buyers respectively were seeking.
