The U.S. dollar traded mixed against other major currencies Wednesday, as investors mainly awaited further progress on U.S. tax reforms.

The U.S. Senate is gearing up this week to start ironing out a tax revamp unveiled by President Donald Trump, just after the GOP lost a major legislative battle.

The Senate will consider a budget resolution, which is the first step in passing tax reform. But the GOP may have thin support, as one Republican lawmaker will be out of town and unable to vote.

Meanwhile, investors also kept a close eye on the newly-released Beige Book from the Federal Reserve.

The report indicated that the U.S. economic activity increased in September through early October, with the pace of growth split between modest and moderate.

On the economic front, U.S. housing starts in September decreased 4.7 percent to a seasonally adjusted annual rate of 1.127 million units, the Commerce Department said on Wednesday. That was the lowest level since September 2016 and followed August's upwardly revised pace of 1.183 million units.

The dollar index, which measures the greenback against six major peers, ticked down 0.02 percent at 93.466 in late trading.

In late New York trading, the euro increased to 1.1788 dollars from 1.1772 dollars in the previous session, and the British pound increased to 1.3199 dollars from 1.3190 U.S. dollars in the previous session. The Australian dollar decreased to 0.7844 dollar from 0.7847 dollar.

The dollar bought 112.93 Japanese yen, higher than 112.15 yen of the previous session. The U.S. dollar rose to 0.9815 Swiss franc from 0.9784 Swiss franc, and it was down to 1.2470 Canadian dollars from 1.2540 Canadian dollars.
