In the U.S. equity market, tech shares, up 1.58 percent led the advance after a modest pullback on Tuesday. IBM Corp IBM.N, which gained 2.9 percent to $168.65, helped pace gains after Barclays upgraded the stock two notches to "overweight" ahead of its quarterly results on Thursday.

Notable laggards were Goldman Sachs Group Inc GS.N, down 1.86 percent and Bank of America Corp BAC.N, off 0.19 percent, after their quarterly results included charges related to the new federal tax law.

The dollar was higher against a basket of major currencies in a choppy session, buoyed by the stronger-than-forecast data on domestic industrial output in December that supported the notion of a steady U.S. economic expansion.

The dollar briefly moved lower after a tweet by a Politico reporter that U.S. Republican Senator Lindsey Graham said he would not vote for a Republican “continuing resolution” stopgap bill to fund the government temporarily.

But the Federal Reserve’s Beige Book report on the economy, which said the U.S. economy and inflation expanded at a modest-to-moderate pace from late November through the end of 2017, while wages continued to push higher, helped the dollar regain its footing.
