The Australian dollar continued to depreciate on Monday, pressured by the strengthening US dollar, which has been buoyed by a surge in US Treasury yields. Investors are flocking to the US dollar as higher yields increase its appeal, pushing the AUD/USD pair lower.

US Treasury yields surged to multi-year highs, supported by expectations that the Federal Reserve will maintain its hawkish stance on interest rates. The yield on the 10-year Treasury note has climbed sharply, reflecting confidence in the US economy's resilience despite higher borrowing costs. This upward momentum in yields has made the greenback more attractive to investors, further dampening demand for riskier currencies like the Australian dollar.

At the same time, Australia’s economic outlook has shown signs of weakening, with softer growth projections and mixed data on domestic demand. These factors, coupled with the Reserve Bank of Australia’s more cautious approach to raising interest rates, have weighed on the Aussie.

The divergence between US and Australian interest rate policies has also widened, with markets betting on continued rate hikes from the Fed while the RBA remains cautious amid slower growth. This difference has made the US dollar more attractive to investors, pushing the Australian dollar lower.

As long as US yields remain elevated and the Fed signals further tightening, the Australian dollar is likely to stay under pressure. Unless there is a significant shift in either country’s economic outlook, the AUD/USD pair could continue its downward trend in the near term.
