Financial Historical Report of Sierra Leone

Basic Data

• Country ISO Code: SL

• Official Currency: Sierra Leonean Leone

• Currency ISO Code: SLE (new leone since July 2022), formerly SLL

• Subdivision: 1 leone = 100 cents (though cents are rarely used due to inflation)

• Issuing Authority: Bank of Sierra Leone

Currency History

• The Sierra Leonean leone was introduced on August 4, 1964, replacing the British West African pound at a rate of 1 pound = 2 leones (i.e., 1 leone = 10 shillings). At introduction, 1 leone was worth half a pound sterling or approximately US$1.4014.

• Initially, the leone was stronger than the US dollar but began to devalue rapidly from the 1980s onward due to economic challenges and inflation1.

• Over the years, inflation caused the leone’s value to plummet, with the US dollar eventually worth thousands of leones by the 2000s1.

• In August 2021, the Bank of Sierra Leone announced a redenomination of the leone, introducing a new leone (SLE) at a rate of 1000 old leones (SLL) to 1 new leone (SLE)15.

• The new leone was introduced in July 2022; old leones remained legal tender until December 31, 2023, and could be exchanged in banks until March 31, 20241.

Banknotes and Coins

• The leone is subdivided into 100 cents, but due to inflation, cent coins are no longer in practical use6.

• Common banknotes in circulation include denominations of 1000, 2000, 5000, and 10,000 leones (old SLL), with new denominations reflecting the redenomination introduced in 2022610.

• Banknotes feature prominent national figures, cultural symbols, and natural heritage, such as the national emblem and the historic Cotton Tree89.

• Sierra Leone has issued commemorative gold and silver coins featuring local fauna and flora, valued by collectors6.

• Coin production was disrupted during the civil war (1991–2002), leading to cash shortages and increased use of foreign currencies in some regions6.

Economic Context

• The leone’s depreciation reflects Sierra Leone’s economic difficulties, including inflation and political instability.

• The redenomination aimed to simplify transactions, improve currency security, and restore confidence in the national currency57.

• The Bank of Sierra Leone continues to manage monetary policy to stabilize the currency and support economic growth.

Summary

• Sierra Leone’s currency history began with the introduction of the leone in 1964, replacing the British West African pound.

• The leone experienced significant inflation and devaluation over decades, necessitating redenomination in 2022.

• The currency remains central to Sierra Leone’s economy, with ongoing efforts to maintain stability and public trust.
