The Rupiah is the official currency of Indonesia, represented by the symbol "Rp." It is subdivided into 100 sen, although sen coins are rarely used in everyday transactions. The currency is issued by the Bank Indonesia, the country's central bank, and is essential for trade and commerce within the nation. The Rupiah has undergone various changes in value due to economic factors, including inflation and government policies. It is important for both local and international businesses operating in Indonesia to understand the currency's exchange rates and economic stability to make informed financial decisions.
