The IFR is available to all member countries, but countries eligible for the Fondo Fiduciario para el Crecimiento y la Lucha contra la Pobreza (FFCLP) are more likely to draw on the Servicio de Crédito Rápido (SCR), which is also concessional.

The IFR is designed for situations in which a full economic program is either not necessary or not feasible in the face of a present balance of payments need that, if not urgently addressed, would result in immediate and severe economic disruption.

In response to the high and urgent funding needs in the face of COVID-19, the access limits under these windows were increased on an interim basis through december 31, 2021. As of january 1, 2022, the annual access limits for the Regular Window and the Major Natural Disaster Window have returned to the pre-pandemic limits of 50% and 80% of quota, respectively.

However, the cumulative access limits in both windows will remain at 150% and 183.33% of quota, respectively, through june 30, 2023.

The level of access in each case depends on the country's balance of payments needs, its repayment capacity, the country's outstanding credit to the International Monetary Fund (IMF), and its history of using IMF resources. Financial assistance provided as part of the IFR is subject to the same financing conditions as the Flexible Credit Line (FCL), the Precautionary and Liquidity Line (PLL) and Stand-By Arrangements, and must be repaid in 3¼ to 5 years.
