revenue declined from 22% of GDP in 2011 to 17% in 2021. 15 African nations hold significant debt risk, and 7 are currently in financial crisis according to the IMF. The region went on to receive IMF Special Drawing Rights of $23 billion in 2021 to assist critical public spending. The economies of the fastest growing African nations experienced growth significantly above the global average rates. The top nations in 2007 include Mauritania with growth at 19.8%, Angola at 17.6%, Sudan at 9.6%, Mozambique at 7.9% and Malawi at 7.8%. Other fast growers include Rwanda, Mozambique, Chad, Niger, Burkina Faso, Ethiopia. Nonetheless, growth has been dismal, negative or sluggish in many parts of Africa including Zimbabwe, the Democratic Republic of the Congo, the Republic of the Congo and Burundi. Many international agencies are increasingly interested in investing in emerging African economies, especially as Africa continues to maintain high economic growth despite current global economic recession. The rate of return on investment in Africa is currently the highest in the developing world. Debt relief is being addressed by some international institutions in the interests of supporting economic development in Africa. In 1996, the UN sponsored the Heavily Indebted Poor Countries (HIPC) initiative, subsequently taken up by the IMF, World Bank and the African Development Fund (AfDF) in the form of the Multilateral Debt Relief Initiative (MDRI). As of 2013, the initiative has given partial debt relief to 30 African countries. In early 2021, the European Investment Bank, with the help of the Making Finance Work for Africa Partnership (MFW4A), surveyed 78 banks in Sub-Saharan Africa for the EIB Banking in Africa study. The banks that took part control nearly 30% of the continent's assets. Almost two-thirds of Banks surveyed tightened lending rules, but more than 80% expanded their use of restructuring or loan moratoriums. Few banks were required to modify their employee levels, while slightly under one-third adjusted their prices. Approximately half of the answering banks had employee guarantees, the majority of which came from the central bank, the government, or an international financial institution. Fiscal stimulus packages in African countries through to mid-2020 amounted to roughly 1–2% of GDP, with monetary stimulus amounting to about 2% of GDP. This is close to the IMF's global average for low-income developing nations, which is around 2% of 2020 GDP over a one-year period from the start of the COVID-19 pandemic. At the
