In this paper we investigate the scaling behavior of the average daily
exchange rate returns of the Indian Rupee against four foreign currencies
namely US Dollar, Euro, Great Britain Pound and Japanese Yen. Average daily
exchange rate return of the Indian Rupee against US Dollar is found to exhibit
a persistent scaling behavior and follow Levy stable distribution. On the
contrary the average daily exchange rate returns of the other three foreign
currencies do not show persistency or antipersistency and follow Gaussian
distribution.Comment: Revised Final Version. In Press Physica
