The dollar was lower against the euro and yen Wednesday after U.S. Treasury data showed a sharp increase in net capital outflow from the United States in July.

The net capital outflow from the United States increased to $97.5 billion in July from a revised outflow of $56.8 billion in June, the Treasury Department said in its Treasury International Capital (TICS) flows report. The department originally reported an outflow of $31.2 billion in June.

The United States posted a trade deficit of $31.96 billion in July.

"The headline number certainly paints a bit of a dark picture with regard to overall demand for U.S. assets," said Omer Esiner, a senior market analyst at Travelex Global Business Payments in Washington.

The euro was at $1.4690 , up 0.2 percent on the day, and near the session peak of $1.4713, the 2009 high.

Against the yen , the dollar was down 0.7 percent at 90.34 yen.
