The dollar index was up 0.10% at 101.30 at 02:30 ET.
In remarks to the Senate, Yellen said Tuesday it would be "unwise" to delay tightening if the pick-up in the U.S. economy remains on track.
She noted the uncertainty regarding plans for fiscal stimulus under the Trump administration.
Yellen is due to testify to the House of Representatives later Wednesday.
U.S. CPI and retail sales figures are due out later in the session.
The dollar added 0.25% to 114.55 yen amid remarks by BoJ Governor Haruhiko Kuroda.
Kuroda said the central bank has no plans to raise its bond yield targets.
