The U.S. dollar resumed its rally on Tuesday after dipping against sterling and the euro a day earlier, putting it back on track for its first monthly gain since September.
The greenback's rally gathered momentum in recent weeks as upbeat economic data led to mounting expectations that the U.S. Federal Reserve will have to raise interest rates more than initially expected.
The dollar index , which measures the currency against a basket of peers, was flat at 104.64, but was still set for a February gain of 2.6%, its first monthly increase since September.
"The dollar has made its rebound - fully justified - on the strength of the January numbers that came through in February, and the repricing for the Fed," said Ray Attrill, head of FX strategy at National Australia Bank, referring to the strong run of U.S. economic data.
Investors now expecting the Fed funds rate to peak just above 5.4% by September, compared with an anticipated peak of around 4.70 at the start of the month.

The dollar on Tuesday gained particularly against the Japanese yen , climbing 0.44% to 136.84, its highest in over two months.
Japan's policy of keeping yields pinned down means the yen is sensitive to yield moves elsewhere, though incoming Bank of Japan (BOJ) Governor Kazuo Ueda said this week it was premature to comment on how the central bank may shift policy.
And on Tuesday, incoming Deputy Governor Shinichi Uchida brushed aside the chance of an immediate overhaul of the BOJ's ultra-loose monetary policy.
"The initial signs from Ueda are that he's in no rush (to change policy), and as long as he's not in a rush if yields go higher then that continues to pressure the yen," said John Hardy, head of FX strategy at Saxo.
Elsewhere, sterling built on its gains from the previous session against the dollar, rising 0.2% to $1.2082.
It surged 1% on Monday after Britain and the European Union announced a new deal for post-Brexit trading arrangements for Northern Ireland, known as the Windsor Framework.
That brightened the outlook for the post-Brexit UK economy, with British Prime Minister Rishi Sunak saying it would pave the way for a new chapter in London's relationship with the bloc.
The euro was flat at $1.0611, having risen 0.6% in the previous session on the news.
