The U.S. dollar edged lower against a basket of major currencies on Tuesday as concerns over the strength of the U.S. economy and expectations that the Federal Reserve will prove accommodative at its meeting this week weighed on the greenback.
The dollar index, which measures the greenback against six major currencies, fell 0.16 percent to 96.37, hovering close to a more than two-week low touched overnight.

The , which has advanced in recent days - helped by the U.S. dollar's weakness - was down 0.18 percent after minutes of the Reserve Bank of Australia's March policy meeting expressed concern about the housing market.
Volatility in foreign exchange markets is at its lowest in five years and analysts say recent decisions by the Fed and other major central banks are contributing.
"Central banks are like a fleet of planes on the runway and they are all kind of circling around the tarmac and no one really wants to take off," said Trang.
Sterling was up 0.14 percent at $1.3273. It pared early gains on concerns that British Prime Minister Theresa May's request for postponing Brexit was running into complications with the European Union.
