The US dollar is the currency most used as an international monetary reference in the world, along with other currencies such as the Euro, the Yen, the Yuan and the British Pound, although all of these are used in a smaller proportion than the currency of the United States.
In many countries that do not have a strong local currency, or even in nations with stable but not internationally relevant currencies, citizens save in US dollars, because US dollars guarantee savings stability that other currencies, due to their volatility, cannot guarantee. Therefore, there is a large amount of cash that is outside the United States, in bank deposits or even domestic savings of millions of people around the world, which increases the demand for cash.
