Currencies: Dollar rises against yen after weak 30-year Treasury auction

The dollar clawed higher Tuesday, overcoming initial weakness after a dovish message from a key member of the Federal Reserve put a lid on the greenback’s upside momentum.

The greenback USDJPY, +0.40% was changing hands at ¥102.20, compared with ¥101.87 late Monday in New York. The U.S. currency weakened to as low as ¥101.42 overnight before regaining its intraday high of ¥102.30 on what traders called short covering. The euro EURUSD, +0.0623% was at $1.1234, essentially unchanged from where it stood late Monday.

The WSJ Dollar Index BUXX, +0.33% a measure of the dollar against a basket of major currencies, was up 0.09% at 86.31.
