Sentiments are fragile and often irrational, but they do matter. Entrepreneurs invest when they are feeling good, and stop investing when doubts creep in. This is what has happened in India. Doubts have crept in, and the self-confidence that had fuelled investment during the past nine months has largely evaporated. Both Indian and foreign investors have once again begun to have doubts about India as a worthy destination for investment. Thus P. Chidambaram faces a heroic task. For no matter how much you tell investors that the fundamentals of the economy have not changed—that it is still the same sound economy as it was two months ago—market sentiments have a life of their own, and they do not always listen to reason.
