The dollar dipped as investors locked in profits after this week's rally, while a Reuters report saying central bankers in the euro zone plan to challenge European Central Bank President Mario Draghi's leadership style underpinned the euro.

U.S. data on Tuesday revealed a surprise widening of the trade deficit last month, which raised speculation that the initially reported 3.5 percent pace of third-quarter U.S. growth could be revised down. That in turn reduced the likelihood that the U.S. Federal Reserve would hike interest rates in 2015.
The Commerce Department said the trade deficit grew 7.6 percent to $43.03 billion, compared with a forecast of $40.00 billion among analysts polled by Reuters.
The data increased the safe-haven appeal of U.S. Treasury notes, pushing down the benchmark 10-year yield and weighing on the dollar. The yield stood at 2.335 percent in Asia, down from its U.S. close of 2.342 percent on Tuesday, when it fell as low as 2.303 percent.
The dollar index was flat on the day at 87.015, after moving away from its four-year high of 87.406 touched on Monday.

The European Commission on Tuesday downgraded its forecast for euro zone economic growth over the next few years, leading investors to raise bets the ECB might consider more action to stimulate the region's economy.
