LOS ANGELES (MarketWatch) -- The euro edged upward during Asian trading hours Thursday, as a coordinated central-bank action to easing dollar-borrowing costs in Europe boosted confidence. The euro EURUSD +0.15% rose to $1.3459, extending its gains from $1.3446 in late North American trade Wednesday after the central bank action was first announced. The dollar index DXY -0.12% , a measure of the greenback against six rival currencies, slipped to 78.273 from 78.345 late Wednesday, but against the Japanese yen, the U.S. unit USDJPY +0.08% rose to ¥77.67 from ¥77.53. The British pound GBPUSD -0.05% was almost flat at $1.5701 from $1.5703 late Wednesday.
