I was writing about it as you posted the question.
I made a post about
Participatory Notes (P-Notes).
SEBI just pricked the FII bubble - at least for the short to medium term.

.
Frankly speaking, I myself would prefer to remove this P-Notes route.
If an investor wants to buy a stock, he should directly buy it and not route it through multiple channels.
If only SEBI and government would make investing process easier and cheaper for foreign investors, there would be no need for Participatory Notes.
Many genuine foreign investors prefer P-Notes to direct investing, as P-Notes are more convenient and cheaper.
RBI has been against P-Notes for a long time now.
It is just a matter of time before P-Notes are completely abolished.
