Authorised dealers may lend in foreign currency under defined categories: branches outside India may extend foreign currency loans in the normal course; authorised dealers may grant loans to constituents for foreign exchange requirements, rupee working capital or capital expenditure subject to prudential norms and RBI guidelines; loans to wholly owned subsidiaries or joint ventures abroad are permitted where the Indian entity holds at least 51% equity and foreign security regulations are complied with; loans secured by RFC, NRE or FCNR funds are allowed per account rules; inter-dealer lending is subject to RBI directions. Borrowing in foreign currency is permitted from head offices, branches, correspondents or permitted entities within limits tied to unimpaired Tier I capital or a fixed threshold, and for export credit subject to RBI guidelines.
