The U.S. dollar declined against other major currencies on Friday as U.S. Federal Reserve Chair Janet Yellen did not mention U.S. monetary policy in her remarks at the annual central bank research conference.

Yellen said on Friday that any changes to the post-crisis financial reforms should be "modest" as these reforms have made the financial system substantially safer and resilient.

However, she made no reference to U.S. monetary policy in her remarks.

Stephen Simonis Sr., chief currency consultant for FXDD Global, said Yellen's speech was largely uneventful and that "the dollar was sold off after Yellen's speech as FX (foreign exchange) traders focused on what she did not say."

The dollar index, which measures the greenback against six major peers, was down 0.54 percent at 92.771 in late trading.

In late New York trading, the euro rose to 1.1876 U.S. dollars from 1.1809 U.S. dollars, and the British pound climbed to 1.2875 U.S. dollars from 1.2804 U.S. dollars. The Australian dollar increased to 0.7935 U.S. dollar from 0.7907 U.S. dollar.

The U.S. dollar bought 109.29 Japanese yen, lower than 109.36 yen of the previous session. The U.S. dollar fell to 0.9574 Swiss franc from 0.9645 Swiss franc, and it edged down to 1.2482 Canadian dollars from 1.2525 Canadian dollars.
