The Australian Dollar weakened to around 0.7005 against the US Dollar during early European trading hours on Monday, reflecting growing market caution. According to FX Street, the AUD/USD pair lost momentum amid a risk-off sentiment driven by uncertainties over the US-Iran peace deal.

Concerns intensified following fresh threats from US President Donald Trump, which heightened doubts around the prospects of a peaceful resolution between the US and Iran. This geopolitical tension contributed to the Australian Dollar's retreat as investors sought safer assets.

For Japanese investors, the AUD's movement underscores the ongoing sensitivity of FX markets to geopolitical developments, which can influence yen cross rates and regional risk appetite.
