Dollar gains against yen, euro, pound

NEW YORK • The dollar gained against the yen, the euro and the pound Monday after data showed that U.S. services industry activity unexpectedly picked up in November, prompting speculation the Federal Reserve may lift interest rates more than recently projected.

The dollar index, which tracks the greenback against six peers, fell 1.4% last week, and 5% in November, its worst month since 2010.
