The Singapore dollar (sign: S$; code: SGD) is the official currency of the Republic of Singapore. It is divided into 100 cents (Malay: sen, Chinese: 分; pinyin: fēn, Tamil: காசு, romanized: kācu). It is normally abbreviated with the dollar sign $, or S$ to distinguish it from other dollar-denominated currencies. The Monetary Authority of Singapore (MAS) issues the banknotes and coins of the Singapore dollar.
As of 2024, the Singapore dollar is the 13th most traded currency in the world. Apart from its use in Singapore, the Singapore dollar is also accepted as customary tender in Brunei according to the Currency Interchangeability Agreement between the Monetary Authority of Singapore and the Autoriti Monetari Brunei Darussalam (Monetary Authority of Brunei Darussalam). Likewise, the Brunei dollar is also customarily accepted in Singapore.
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.
