Introduction:
The Saudi currency, known as the Saudi Riyal, has a rich history that dates back to the early 20th century. Over the years, the currency has undergone various changes and developments to meet the needs of the growing economy and population of Saudi Arabia. This case study will explore the evolution of the Saudi currency and its impact on the country's economy.

Background:
The Saudi Riyal was first introduced in 1927 as the official currency of signature saudi Arabia. Prior to this, various currencies like the Indian Rupee and the Ottoman Empire's currency were used in the region. The Riyal was pegged to the British Pound until 1986, when it was pegged to the US dollar.

In 1952, the Saudi Arabian Monetary Agency (SAMA) was established to regulate the monetary and banking system in the country. This move helped to stabilize the economy and strengthen the value of the Riyal.

Evolution:
In the early years, the Saudi Riyal was issued in denominations of 1, 5, 10, 20, 50, and 100 Riyals. These banknotes featured images of the country's landmarks, symbols, and leaders. In 1961, the 500 Riyal banknote was introduced to accommodate the growing need for higher denominations.

In 1984, coins were introduced alongside the banknotes to facilitate transactions and reduce the dependence on paper currency. The coins were issued in denominations of 1, 5, 10, 25, and 50 Halalas, with the Halala being equivalent to 1/100 of a Riyal.

In 1999, the Saudi government introduced a new series of banknotes and coins with enhanced security features to combat counterfeiting. These changes helped to maintain the integrity of the currency and ensure its value in the international market.

In recent years, the Saudi Riyal has faced challenges due to fluctuations in the global oil market, which is a significant source of revenue for the country. The government has taken measures to diversify the economy and reduce its dependence on oil exports to protect the value of the Riyal.

Impact:
The stability and strength of the Saudi currency have played a crucial role in the country's economic growth and development. The Riyal's peg to the US dollar has helped to maintain a stable exchange rate and attract foreign investment.

The availability of various denominations of banknotes and coins has made it easier for people to make transactions and carry out daily activities. The use of advanced security features has reduced the risk of counterfeit currency circulating in the market.

In conclusion, the evolution of the Saudi currency reflects the country's journey towards economic prosperity and stability. The government's efforts to modernize the currency and maintain its value have contributed to Saudi Arabia's position as a key player in the global economy.
