ما هي العملة الأرخص في العالم؟

That is correct. By nominal exchange rate standards, the Iranian Rial (IRR) is widely cited as the lowest-valued currency in the world.

The primary factors driving this ongoing devaluation include:

• International Sanctions: Long-standing restrictions have severely limited Iran's oil exports and its integration into the global financial network (such as the SWIFT system), choking off vital inflows of foreign currency.

• High Inflation: Persistent double-digit inflation (often exceeding 40%) rapidly erodes the purchasing power of domestic wages and savings.

• Foreign Exchange Pressures: A heavy reliance on unofficial black-market exchange rates reflects a deep loss of confidence in the formal economy.

Did you have a specific question about how exchange rates are calculated, or are you looking at the performance of other heavily devalued currencies (like the Lebanese Pound or Vietnamese Dong)?
