US dollar exchange rate - USD/PLN

Coins called "dollaro" were produced in the Spanish colonies in the Americas. One coin had a value of eight reales - this was the case until the end of the 17th century, when the dollar became a separate national currency. The dollar symbol, a crossed-out S, also derives from the way the value of $1 is written as an eight in brackets. Over time, the notation underwent further transformations until it acquired its current form.

As for the name of the dollar itself, its "great-grandfather" is the thaler, a coin minted from ounces of silver in the 16th century. The value of the dollar was convertible into an ounce of gold for many years - finally, references of the value of the dollar to gold were only abolished in 1973.

Until the second half of the 19th century, dollars functioned only in coin form, while the first banknotes appeared during the Civil War in 1861. Right from the start, the dollars had a distinctive green reverse to make them more difficult to counterfeit.

In the 19th century, various banking systems were introduced in the United States and financial crises such as the Panic of 1837 and the banking crisis of 1907 contributed to the need for a more centralised financial system.

Established in 1913, the US Federal Reserve System, which is in charge of issuing dollars, plays a key role in shaping monetary policy and economic stability in the United States. It also has a major impact on exchange rates, investment funds and stock markets around the world.

The US dollar is considered the most important currency in the world due to the dominant role of the United States in the global economy. The political and economic stability of the US, its extensive financial system and the dollar's role as a major reserve currency make it trusted by investors and central banks. Furthermore, the widespread adoption of the dollar in international trade transactions strengthens its position as the most widely used currency for international payments.

US dollars are used to make most settlements and determine the values of the most lucrative assets such as gold, platinum and other precious bullion, food, oil and many others. Consequently, the USD exchange rate has a significant impact on the prices of these raw materials, which are denominated in dollars.
