The euro rose against the dollar in light trading on Monday after Greece approved new austerity measures, but worries about hurdles in the country's bid to avoid a disorderly default ate into gains.
The Greek parliament passed a package of wage, pension and job cuts on Sunday, boosting hopes that Athens would secure more rescue funds from the European Union and International Monetary Fund ahead of a March bond redemption.
The euro was up 0.36 percent at $1.3220, off a session high of $1.3283. The single currency faces resistance at last week's two-month high of $1.3322 and the 100-day moving average at $1.3325, while traders said a large option expiry at $1.3300 was likely to restrict further intra-day gains. The euro gave up early gains versus the yen to trade near flat at 102.32 yen.
