The key to that change is in the hands of the committee set up on March 20 by the RBI to produce a road map for full convertibility of the rupee on the capital account. The group, led by former RBI deputy governor S.S. Tarapore, is set to complete its report by July 31 this year. Convertibility is a political hot potato. There is no single definition, but economists generally agree that full convertibility on the capital account implies the freedom to buy and sell assets, like equity, debt or land across international borders at prices determined by the prevailing market rate of exchange. Tarapore himself defines it as the freedom to exchange local financial assets for foreign financial assets and vice versa at market rates without encumbrance.
