The ISO 4217 currency code for the Saudi Arabian Riyal.


ISO 4217 code for the Saudi Arabian riyal. It became the official currency of the Kingdom at its establishment in 1932; it is the successor currency to the Hejaz riyal. Between 1986 and 2003, the riyal was pegged to Special Drawing Rights, but in practice, this was effectively a peg to the U.S. dollar. The peg was officially changed to the dollar in 2003 and has been in effect since (with the exception of a brief period toward the end of 2007). It is issued by the Saudi Arabian Monetary Agency.
