The IDA lends to countries with the aim to finance projects that will develop infrastructure and improve education, healthcare, access to clean water and sanitation facilities, and environmental responsibility. It is considered to be the soft lending window of the World Bank, while the IBRD is considered to be the hard lending window. The association offers grants and loans with maturities ranging from 25 to 40 years, grace periods of 5 to 10 years, and interest rates of 2.8% or 1.25% depending on whether the borrower is a blend country and to which degree it is eligible. Regular IDA-eligible borrowers may take advantage of no-interest loans.
