The dollar was under pressure on Tuesday, weighed by growing expectations the Federal Reserve would shift to a more accommodative policy stance this week and concerns about slower U.S. economic growth.
The dollar index, which measures the greenback against a basket of six major currencies, was a shade lower at 96.495, hovering close to a two-week low. The index has lost 1.2 percent after hitting a three-month high of 97.710 on March 7.
The dollar has weakened in recent sessions on growing expectations the Fed will strike a dovish tone at its two-day policy meeting due to start later on Tuesday.
As the dollar took a breather, other major currencies advanced by default. The yen rose 0.1 percent to 111.27 yen per dollar, extending its gains to a third session.
Sterling also gained, rising 0.1 percent to $1.3268. It had seesawed overnight after the speaker of Britain's parliament said Prime Minister Theresa May's Brexit deal could not be voted on again unless a different proposal was submitted.
