Singapore, August 03 (QNA) - The dollar was little changed on Monday, while the Japanese yen surged to a three-month high as investors anticipated the possibility of further intervention by Tokyo following last week's joint action with Washington to support the currency.

The yen climbed as much as 1% in Asian trading to 155.20 per dollar, its strongest level in about three months, before trimming some of its gains. It was last up 0.7% at 156.46 per dollar.

The Japanese currency also strengthened against other major currencies, including the euro and sterling, reinforcing market expectations that Japanese authorities could intervene again in the foreign exchange market if needed.

The yen's advance weighed on the US dollar, lifting the euro to a six-week high of $1.1559 in early Asian trade, while sterling hovered near a two-week peak of $1.3470.

The US Dollar Index was little changed at 99.70, after falling more than 1.5% last week.

Elsewhere in the currency market, the Australian dollar climbed to a more than one-month high of $0.7069, while the New Zealand dollar rose to a two-month high of $0.59075. (QNA)
