The euro remained near a seven-month low against the dollar at around $1.2640 today.
The dollar was supported, shrugging off the Philadelphia Federal Reserve's index for business conditions in May, which slumped to 7.3, almost a two-year low, from 25.3 in April.
Economists had expected a more moderate fall to 19.0.
The dollar held near a one-month high against the yen after a weak regional factory report failed to dent expectations for US interest rates to keep rising steadily.
The yen hardly budged after the Bank of Japan (BOJ) said that it would allow temporary breaches of a target it sets for funds in the banking system - a move analysts saw as a technical fine-tuning that reflected healthier finances for Japan's banks.
Earlier the dollar fetched 107.55 yen, hardly changed from before the BOJ announcement and within striking distance of a one-month high of 107.79 yen hit on Monday and again on Wednesday.
