U.S. dollar bulls are enjoying their moment in the sun after a trying start to the year, and analysts told CNBC the good times could continue.
The greenback strengthened to a seven month high against the yen in early trade on Wednesday, while the U.S. dollar index, which tracks the dollar's value against seven major currencies, has rallied nearly 4 percent since the beginning of July on positive U.S. economic sentiment. On Tuesday, the index hit an over one-year high of 82.930, following lackluster performance in the first four months of the year when it slumped 1.2 percent.
Expectations that U.S. monetary policy will continue to diverge from policy in Europe and the U.K. will send the dollar index higher as investors price in a U.S. rate hike, according to Capital Economics.

"The dollar is now the strongest it has been against the other major currencies in over a year. But we doubt its rally is over given the relative prospects for monetary policy in the U.S. and elsewhere," analysts at Capital Economics, wrote in a note published Monday.
"By end-2015, we expect the dollar to have strengthened further to $1.25 against the euro, to $1.60 against sterling, and to 120 yen," they added.
The Federal Reserve sparked rate hike speculation in mid-2013 when it unveiled plans to taper its quantitative easing program. But the timing of a rate hike remains uncertain.
Last month's Fed minutes showed some policy committee members want to hike rates promptly amid improvements in the economy. Yet, most members feel that more data are required before taking action.
