Dollar Teeters Near Multi-Month Lows Amid Debt Concerns

The US dollar is trading near multi-month lows due to concerns over debt and the potential impact of new sanctions on Iran. The Treasury's promise to buy back more long-dated bonds has added to market uncertainty, with traders awaiting details on policy speeches in the US and Japan this week.

Meanwhile, trade tensions between the US and Canada have weakened the Canadian dollar by 0.5% to C$1.3836 per dollar. The euro is trading at $1.1665, down slightly from last week's three-month top but still near its highest level in months.
