Singapore, August 20 (QNA) - The US dollar stood at three-month lows on Thursday after the Treasury Department moved to calm a ​bond market rout that had pushed long-end yields to their highest since 2007.

The dollar index, which ‌measures the US currency against six other units, was at 98.938, around its lowest level since mid-May.

The euro was at $1.1676, perched at the highest level since late May. The dollar weakness provided ⁠some relief to the Japanese yen as the fragile currency pulled away from the closely watched 160 level, at 158.32 per dollar. Sterling was ​at $1.3603, while the Swiss franc last bought 0.7981 per US dollar, near its two-month high.

​The 30-year Treasury yield rose to a 19-year high of 5.337% earlier this week, prompting the US Treasury ⁠to unveil plans on Wednesday to double liquidity support buyback operations for longer-dated bonds.

The 30-year yield was last at 5.184% after dropping 9 ​basis points following Wednesday's decision. (QNA)
