In April 2007, I had written an opinion piece titled Currency futures now. Today, in Financial Express I have an opinion piece titled Now, currency futures. In some respects, we do make progress in India. Update: See this article by Rajarshi Singhal in Economic Times today (27th August).
I found a search for `currency futures' on this blog to be a mildly interesting review of the events from 2007 onwards in this space.
