Banknotes of Omani Rials (OMR)
In 1970, banknotes were introduced by the government in denominations of 100 baiza, ¼, ½, 1, 5 and 10 rial saidi. These were followed in 1973 by notes for 100 baiza, ¼, ½, 1, 5 and 10 Omani rials issued by the Oman Currency Board. From 1977, the Central Bank of Oman has issued notes, with 20 and 50 rial notes introduced that, followed by 200 baisa notes in 1985.
Notes currently circulating are: 100 baisa, 200 baisa, ½ rial, 1 rial, 5 rial, 10 rial, 20 rial, 50 rial. A new 1 rial note is now in circulation alongside the 1970 note which is still accepted. The new 1 rial note is red, similar to the 5 rial note. Although the 100 baisa and 20 rial notes are both green, the former is considerably smaller, and thus the two are easily distinguishable.
Exchange rates of Omani Rial (OMR)
From 1973 to 1986, the rial was pegged to U.S. dollar at 1 rial = 2.895 dollars. In 1986, the rate was changed to 1 rial = 2.6008 dollars, which translates to approximately 1 dollar = 0.384497 rial. The Central Bank buys U.S. dollars at 0.384 rial, and sell U.S. dollars at 0.385 rial. Before Malta's adoption of the euro on 1 January 2008, it was the fourth highest valued currency unit after the Kuwaiti dinar, Maltese lira, and the Bahraini dinar. Now it is the third highest.
