External Commercial Borrowings (ECBs) are commercial loans in foreign currency or Rupees raised by eligible Indian entities from recognized non-resident lenders, such as foreign banks and international financial institutions, to fund business expansion and modernization. These loans are subject to specific regulations set by the Reserve Bank of India (RBI), including parameters on minimum maturity periods, permissible end-uses, and all-in-cost ceilings, all of which must be followed to obtain a Loan Registration Number (LRN) from the RBI.
