Details for Ugandan Shilling (UGX) Currency

Introduction : The Ugandan Shilling (UGX), denoted by the symbol USh, is the official currency of the Republic of Uganda. Subdivided into 100 cents, it is issued and managed by the Bank of Uganda. The Shilling serves as the core of Uganda’s financial and economic infrastructure, facilitating all forms of transactions including trade, government payments, salaries, and daily purchases. It is used across various sectors such as agriculture, retail, transport, and services. The currency reflects Uganda’s national identity and economic journey, playing a vital role in financial planning, economic policy, and national development initiatives.

History & Origin : The Ugandan Shilling was introduced in 1966, replacing the East African Shilling at par after Uganda gained independence from British colonial rule in 1962. The initial currency featured national emblems and significant symbols, marking a break from colonial monetary systems. Over time, the Shilling underwent multiple redesigns to enhance security, accommodate inflation, and reflect changes in national leadership and economic priorities. The Bank of Uganda, established in 1966, oversees the printing and regulation of the currency.

The Bank of Uganda manages the currency through monetary policy, aiming to control inflation, stabilize exchange rates, and promote financial inclusion and growth.
