London: The dollar and the yen came under pressure today as investors positioned for riskier currencies, hopeful of a breakthrough in talks between the United States and Iran. The euro held steady at $1.1782, while sterling traded at $1.35225, both down about 0.1 percent on the day.

According to Oman News Agency, the risk-sensitive Australian dollar dipped 0.1 percent to $0.7171 in early trading. The dollar index, which tracks the greenback against a basket of currencies including the yen and the euro, steadied at 98.087 after falling 0.2 percent in the previous session. The yen was flat at 158.955 per dollar, hovering close to the 160 level - a threshold traders see as a potential trigger for intervention. The New Zealand dollar traded at $0.59085, up 0.3 percent.
