The U.S. Dollar swung between gains and losses on Wednesday after it reached its strongest level in a week against the Japanese Yen yesterday and declined after the Bank of Japan announced more monetary easing as the inflation eases. The so-called Greenback rose 0.1% to 104.42 yen and traded at 103.97 after the BoJ revealed its stimulus plans, while it was seen at $1.3561 per Euro.
