All Currencies

The strongest currency by face value against the US Dollar is the Kuwaiti Dinar (KWD), where 1 KWD buys roughly 3.26 USD. The Bahraini Dinar (BHD) is second at around 2.65 USD, followed by the Omani Rial (OMR) at about 2.60 USD. However, "strongest" can also mean purchasing power (Swiss Franc, British Pound) or global influence (US Dollar - involved in 88.5% of all forex trades according to the BIS).

The weakest currencies by face value against the US Dollar include the Iranian Rial (IRR), Vietnamese Dong (VND), and Indonesian Rupiah (IDR). A low face value does not necessarily mean a weak economy - Vietnam and Indonesia have rapidly growing economies. The currencies with the steepest recent declines are typically those hit by hyperinflation or political instability, such as the Turkish Lira and Argentine Peso.

According to the BIS 2022 Triennial Survey, the most traded currencies by share of global FX volume are: 1. US Dollar (88.5%), 2. Euro (30.5%), 3. Japanese Yen (16.7%), 4. British Pound (12.9%), 5. Chinese Yuan (7.0%), 6. Australian Dollar (6.4%), 7. Canadian Dollar (6.2%), 8. Swiss Franc (5.2%), 9. Hong Kong Dollar (2.6%), 10. Singapore Dollar (2.4%). Percentages total 200% because each trade involves two currencies.

There are approximately 180 currencies recognized as legal tender by the United Nations. However, only 20-30 account for the vast majority of global forex trading. Many small nations use another country's currency (e.g. Ecuador uses the USD, Montenegro uses the EUR). ExchangeRates.com tracks 28 of the most actively traded currencies, covering over 95% of global FX volume.

Kuwait has the highest-valued currency in the world. The Kuwaiti Dinar (KWD) is worth more than 3 US Dollars, largely because Kuwait is a major oil exporter with a small population and significant sovereign wealth reserves. The Bahraini Dinar and Omani Rial are also among the world's highest-valued currencies for similar reasons - small, oil-rich Gulf states with pegged or managed exchange rates.

Exchange rates are driven by: interest rate differentials between central banks (the biggest short-term driver), inflation rates, trade balances, economic growth, political stability, and market sentiment. When a central bank raises interest rates, its currency typically strengthens because higher rates attract foreign investment. Over the long term, currencies tend to reflect the relative economic health of their countries.

A currency code is a three-letter identifier defined by the ISO 4217 standard. The first two letters usually represent the country (US for United States, GB for Great Britain) and the third represents the currency name (D for Dollar, P for Pound). For example: USD = US Dollar, GBP = Great British Pound, JPY = Japanese Yen. These codes are used universally in banking, trading, and travel. See our full list of currency codes and symbols.
