IMF Standing Borrowing Arrangements
While quota subscriptions of member countries are the IMF's main source of financing, the Fund can supplement its quota resources through borrowing if it believes that they might fall short of members' needs. Through the New Arrangements to Borrow (NAB), the IMF's main backstop for quota resources, a number of member countries and institutions stand ready to lend additional resources to the IMF.
The NAB is a set of credit arrangements between the IMF and 38 member countries1 and institutions, including a number of emerging market countries. The NAB is used in circumstances in which the IMF needs to supplement its quota resources for lending purposes. Once activated, it can provide supplementary resources of up to SDR 370.0 billion (about $508 billion) to the IMF.
The General Arrangements to Borrow (GAB) can also be used in limited cases.
