European stocks edge higher at open

Europe's main stock markets nudged higher Monday, with London's benchmark FTSE 100 index adding 0.18 percent to 6,787.40 points.

Frankfurt's DAX 30 gained 0.05 percent to 11,679.42 points and the CAC 40 in Paris won 0.19 percent to 5,134.16 compared with Friday's close.

The dollar climbed against the euro on expectations of a US interest rate rise by the end of the year.

Focus remained firmly on Greece, where banks reopened Monday after a three-week shutdown imposed to prevent a run on ATMs from crashing the financial system.

But citizens woke up to widespread price hikes as part of a cash-for-reform deal with the country's creditors.

The government is meanwhile expected to make a 4.2 billion euro payment Monday to the European Central Bank (ECB), made possible by the granting of a short-term "bridge" loan of 7.16 billion euros by the European Union ahead of the weekend.
