NEW YORK, July 23 (Reuters) - The euro strengthened on Thursday, briefly rising above $1.10 for the first time in a week, as the Greek parliament approved a second set of reforms required to start negotiations with lenders in a bid to avert bankruptcy.
The greenback stalled against other major currencies despite expectations that the U.S. Federal Reserve would raise interest rates by year end.
Of Athens' latest move toward a bailout, "it's perceived as a positive for the euro. Greece might even be perceived as taking the initiative to revive talks with creditors," Paul Christopher, global market strategist at Wells Fargo Investment Institute in St. Louis.
Other analysts downplayed the pop in the euro, as the long-term ability of Greece to stay solvent and keep its membership in the euro zone remains in doubt. ID:nL5N1034YN
"The market has been short euro. It's not surprising to go through these periodic bouts of (short-covering) squeeze," said Vassili Serebriakov, currency strategist at BNP Paribas in New York.
The euro was last up 0.6 percent against the dollar and yen at $1.1000 EUR= and 136.19 yen EURJPY= , respectively.
The greenback pared losses briefly versus the yen after the government said first-time filings for unemployment benefits fell to 255,000 last week, the lowest since November 1973. This supported the view of an improving jobs market that may allow the Fed to raise interest rates as early as September. ID:nL1N10317J
The dollar resumed its earlier weakness as U.S. Treasury yields fell to two-week lows on growing losses on Wall Street and deflation worries from falling commodity prices. It was down 0.1 percent at 123.79 yen JPY= but held above a global session low of 123.68 yen. .N US/ O/R
The dollar index .DXY was last down 0.5 percent at 97.094.
