not sure what you are trying to say but only 12%? find a trustworthy guy in India and deposit your money in any Indian bank with a return of 9% interest a year fixed. 9% annual returns fixed without any tension and if you want to make it 9.25% annual then invest money up to 3 years.
Although not sure how hard is for you to find a guy and arrange things but lately lots of FII's are investing in Indian markets.
You sir, have no idea what you're talking about.
Only 12%? 12% ROI is pretty good actually.
Also, if he considers investing in an Indian Fixed Deposit scheme (which by the way is meant specifically for Resident and Non-resident Indians) through some channel that becomes an outright violation of the Foreign Exchange Management Act.
And even if he approaches the FII route, there is no assurance on the returns and plus there is a lot of work involved considering the new RBI and SEBI regulations in place.
P.S - Indian here.
