What is the difference in margin requirement between commodes vs equity

I understand there is increased margin requirement in last week of expiry in equity.

Is it same in commodity like Gold and silver?
I mean margin is increased in final week?

Can we take physical delivery of Gold if its in the money …? @ShubhS9

I have the same question about currency futures and options. i.e. usdinr

Yes, additional margins are applicable, these are charged by the exchange, you can check this on the contract specifications page on MCX website.

No, we don’t allow physical settlement of Commodity derivatives and ask clients to square-off the position before start of delivery period. Explained here.

Currency F&O are cash settled, there are no additional margins applicable.

I would like to know why?
