Dollar edges higher

The dollar enjoyed a small rebound on Monday as investors bought back the greenback following its plunge to three-year lows.

The U.S. currency has been hurt by a variety of factors this year, including concerns that Washington might pursue a weak dollar strategy and the perceived erosion of its yield advantage as other countries start to scale back easy monetary policy.

Confidence in the dollar has also been shaken by mounting worries over the U.S. budget deficit, which is projected to balloon to $1 trillion in 2019 amid a government spending splurge and large corporate tax cuts. The return of risk appetite last week after a big stock market fall in early February had also been detrimental to the dollar, but on Monday the U.S. currency found its feet as some investors bought the dollar after the recent falls.

The dollar index was up 0.1 percent at 89.215, off a low of 88.253 hit last week, which was the weakest level for the U.S. currency since December 2014.

Against the euro, the dollar rose 0.2 percent at $1.2399 with traders pointing to crucial business surveys later this week that could give the single currency some more direction.

Versus the yen the dollar gained 0.3 percent to 106.58 yen but remained down 2.3 percent this month.

“The fact that the dollar sell-off ran out of steam on Friday afternoon does not lead me to hope that it is over," Commerzbank analysts said in a note.
