The Australian Dollar (AUD) plays an important role in trading and investing in international financial markets. It is widely used in currency pairs and is seen as a safe haven currency due to its stability and liquidity. The AUD is also recognised as an attractive currency for foreign investors, as it is relatively low risk and offers good returns. Additionally, the AUD is widely used as a hedge against global market volatility and economic uncertainty, as it is less exposed to fluctuations in the international market. As a result, it is often used to diversify portfolios and reduce risk.
