Extending its losses for the fourth day, the Indian rupee on Thursday depreciated by 25 paise in early trade to 47.59 against the US currency, largely on the back of dollar's gains against other major units and on heavy month- end demand from oil companies.

At the Interbank Foreign Exchange (Forex) market, the domestic unit traded 25 paise down at 47.59 a dollar in early trade. Yesterday, the rupee ended 43 paise lower at 47.34/35 against the US currency.
