It is very difficult to bolster the rupee, in the long run, by one or two measures; it would take a reform, and a sustained approach first.
Probably the wealth of India (agri based resources) has not been made effective use of by any Govts. Instead we have shifted to expand our services industry, mainly based on IT, to bolster our forex inflows. FDI, is another. This is primarily to bridge the deficit in the forex inflow, with the outflow - a sort of natural hedge. Our imports are varied and that impacts us quite heavily, esp with the rupee on a nosedive; primary imports being coal, oil etc (energy related), I think.
To curtail the imports we have to become:
1) An energy sufficient country, or
2) Use energy optimally.
We are trying to do 1 while failing miserably in 2. The mischief had already been done, imo, when the GOI subsidised petroleum and gas in the crazy hunt to keep up with the modernized countries. Yes, we have probably achieved that, but at a cost! We have all the latest electronic gadgets, but no electricity to run them. A section of the society enjoys extreme luxury while one section can hardly find one square meal per day.
All our policies have failed to achieve a growth that reflects our wealth, and is sustainable. A growth that makes us strong.
I want to stop now and say that we were unprepared for liberalization when it happened.
P.S. I believe that the BSE is a manipulated number (and I never trust in it).
