The Australian Dollar (AUD) is the official currency of Australia, used by investors and financial markets worldwide. It is a reliable, stable currency backed by the Australian economy, making it a popular choice for international trade. The AUD also serves as a safe-haven currency in times of global uncertainty and market volatility, as it is relatively unaffected by external events. As a result, many investors and financiers use the AUD to diversify their portfolios and hedge against external risk. Furthermore, its regional proximity to major Asian markets makes it an attractive choice for investors looking to access the Asian market.
