Concept:International organisations are set up with different purposes; the IMF focuses on short-term balance of payments support.
Explanation:A temporary balance of payments problem occurs when a country's imports exceed its exports, causing a shortage of foreign exchange.
The International Monetary Fund was founded in 1944 to promote international monetary cooperation and facilitate trade.
One of its main functions is to provide short-term loans to member countries facing balance of payments difficulties.
These loans help countries stabilise their currencies and continue paying for essential imports.

The Economic Commission for Africa and the African Development Bank focus on regional economic development in Africa.
Hence, the institution established to help solve temporary balance of payments problems is the International Monetary Fund.
