The rupiah (symbol: Rp; currency code: IDR) is the official currency of Indonesia, issued and controlled by Bank Indonesia. Its name is derived from the Sanskrit word for silver, rupyakam (रूप्यकम्). Sometimes, Indonesians also informally use the word perak ('silver' in Indonesian) in referring to rupiah in coins. The rupiah is divided into 100 cents (Indonesian: sen), although high inflation has rendered all coins and banknotes denominated in cents obsolete.
The rupiah was introduced in 1946 by Indonesian nationalists fighting for independence. It replaced the Japanese-issued version of the Netherlands Indies gulden which had been introduced during the Japanese occupation in World War II. In its early years, the rupiah was used in conjunction with other currencies, including a new version of the gulden introduced by the Dutch. The Riau Islands and the Indonesian half of New Guinea (Irian Barat) had their own variants of the rupiah in the past, but these were subsumed into the national rupiah in 1964 and 1971, respectively (see Riau rupiah and West Irian rupiah).
Nigerian Naira
The naira (sign: ₦; code: NGN; Yoruba: náírà, Hausa: نَيْرَ, romanized: naira, Igbo: naịra, Tyap: nera) is the currency of Nigeria. One naira is divided into 100 kobo.
The Central Bank of Nigeria (CBN) is the sole issuer of legal tender money throughout the Federal Republic of Nigeria. It controls the volume of money supplied in the economy in order to ensure monetary and price stability. The Currency Operations Department of the CBN is in charge of currency management, through the designs, procurement, distribution and supply, processing, reissue and disposal or disintegration of bank notes and coins.
A major cash crunch occurred in February 2023 when the Nigerian government used a currency note changeover—delivering too few of the new notes into circulation—to attempt to force citizens to use a newly created government-sponsored central bank digital currency. This led to extensive street protests.
