The Saudi Riyal (SAR) is the official currency of the Kingdom of Saudi Arabia. It is subdivided into 100 halalas and is issued by the Saudi Arabian Monetary Authority. The symbol for the Saudi Riyal is ر.س, and it is widely used in both cash and electronic transactions throughout the country. The Saudi Riyal is pegged to the US dollar, maintaining a fixed exchange rate that helps stabilize the economy. This peg supports trade and investment, making the Riyal a crucial part of the country's financial system, especially given its significant oil exports and economic activities related to the OPEC organization.
