whether anybody has knowledge about what will be its impact

Can someone please help with the below:

  1. Will stock options continue to remain European style or will they become American style

  2. Will calls/puts become more expensive as there will be higher impact costs for writers? By ‘impact cost’, I mean extra STT, brokerage, etc. that will come in because of physical settlement

  3. Will there be higher impact costs for buyers as well? Will they like to buy the options cheaper? If so, then bid-ask spread will increase? Has this happened in other markets and was it resolved in terms of liquidity and bid-ask spreads?

  4. What will be the approximate impact costs for a buyer and for a writer? In % terms, how much costs will increase

  5. Will future premium/discount over spot widen?

  6. Is it business-as-usual on index derivatives?

  7. Do they want to implement physical settlement for all current FnO stocks?

Regards

Stocks which are going to physical settlement , i think will ,become European

I think bid-ask spread will increase and also , all these 46 stocks probably behave like , weekly bank nifty . for rest of the points , i am expecting views from fellow traders

  1. EU style only for those in the list
    2)doubtful since it’s only for investors
  2. us mkt don’t have much futures liquidity as they approach expiry. Similar to options in expiry week.
    4)waut n watch.
    5)wait n watch
    6)yes,and will be
  3. read sebi circular dated April 11
    Theyve cooked up a methodology for identifying stocks based on transaction amt etc. Stks which meet the criteria will continue to be cash settled and which don’t bcom physical settled.
    This is to revised every 6.months.

EU is cash settled
American is physical.

I think , EU and American styles are related to time of exercise, not cash or physical settlement , European options can be exercised only on the expiration date , where as American style option can be exercised at any time ( let me edit that portion of my answer)
If SEBI makes option style which are going to physical settlement to American style , than , that particular stocks options volume dry down drastically !!
