由于投资者继续评估美中贸易协定对全球经济的影响，澳元在上一交易日面临加剧的波动后，周二稳定在0.638美元左右。周末在瑞士成功谈判后，华盛顿和北京达成协议，在90天内将各自的关税分别削减至30%和10%，缓解了贸易紧张局势，降低了全球经济衰退的风险。由于澳大利亚与中国有着深厚的出口关系，特别是在大宗商品方面，澳大利亚对美中贸易发展仍然高度敏感。与此同时，国内数据显示消费者和企业信心均有改善，为澳元提供了一些额外支撑。在货币政策方面，人们普遍预计澳大利亚储备银行将在下周的会议上再降息25个基点，因为它在全球不确定性中继续努力刺激增长。

The Australian dollar stabilized around $0.638 on Tuesday after facing heightening volatility in the previous session as investors continued to assess the impact of the US-China trade agreement on the global economy. After successful negotiations over the weekend in Switzerland, Washington and Beijing reached a deal to slash their respective tariffs to 30% and 10% for 90 days, deescalating trade tensions and reducing risks of a global recession. Australia remains highly sensitive to US-China trade developments due to its deep export ties with China, particularly in commodities. Meanwhile, domestic data showed an improvement in both consumer and business confidence, offering some additional support to the Aussie. On the monetary policy front, the Reserve Bank of Australia is widely expected to cut interest rates by another 25 basis points at its meeting next week, as it continues efforts to stimulate growth amid global uncertainty.
