Overview

The ariary (symbol: Ar; ISO 4217 code: MGA) is the currency used in Madagascar (Madagascar). It functions through coins and banknotes issued by the country's central monetary authority and is used for everyday transactions, savings and pricing across the island nation. The ariary is notable among modern currencies for not following a decimal subunit system: its traditional subdivision is the iraimbilanja, equal to one fifth of an ariary.

Characteristics

Unlike the majority of contemporary currencies, the ariary is non‑decimal. This means the principal unit is not divided into 100 smaller units. Instead, the ariary is associated with the iraimbilanja, and the two have a fixed ratio. In practice, the very smallest denominations are rarely used in daily cash trade because inflation and convenience have reduced demand for low‑value coins and notes.

History and etymology

The names derive from older Malagasy monetary terms. The word ariary historically identified a silver coin—sometimes translated as a dollar in older accounts—while iraimbilanja literally means "one iron weight" in Malagasy and referred to a coin that represented one fifth of an ariary. These terms reflect pre‑colonial and early colonial patterns of exchange and coin use, and they were retained when the modern national currency system was established. For background on the concept of non‑decimal currencies see non‑decimal currencies.

Usage and importance

In everyday life, prices, wages and contracts are stated in ariary. The central bank issues denominations intended to serve a range of transaction sizes; however, small subunits such as the iraimbilanja are now of limited practical importance. During transitional periods when currency systems change, both old and new units may be referenced in pricing and by older generations.
