• AUD/USD value has dropped due to consistent gains in the US Dollar.
• Monetary policy divergence between the RBA and the Fed could provide some relief to AUD/USD.
• Uncertainty surrounding China's economic outlook and stimulus efforts remains a key challenge for the Aussie.

The AUD/USD pair has declined in the Monday session, following consistent gains in the US Dollar. The pair fell by 0.80% to 0.6655 at the time of writing. The declines in the Aussie have been attributed to concerns over China's stimulus measures and recent weakness in copper prices.

However, monetary policy divergence between the Reserve Bank of Australia (RBA) and the Federal Reserve (Fed) could provide some support to AUD/USD, but the uncertainty surrounding China's economic outlook remains a key challenge for the currency. Investors remain vigilant to incoming Aussie data, as it might delay the start of the RBA’s easing cycle.
