Global benchmark Brent crude LCOc1 climbed 0.3 percent to $46.18, set to end the week 4.7 percent higher and U.S. crude at $43.89 a barrel was on track for a 5 percent weekly rise.

DATA DUMP
Back in Europe, there was reassuring news from the bloc's largest economy Germany, where economic growth slowed less than expected in the second quarter thanks to solid exports and state and consumer spending. markets will also sift through a slew of U.S. data, notably retail sales, due later in the session for latest cues about the world's largest economy and whether it is robust enough to withstand further monetary tightening.
U.S. retail sales are expected to show a 0.4 percent monthly increase in July, according to the median estimate of 64 economists polled by Reuters. ECONUS

Euro zone bond yields also edged back from record lows as the rise in oil prices eased nagging deflation concerns and follow Williams' Federal Reserve rate hike comments. we had that drop to a record low in July, German bond yields have been pretty stable and oil prices will have a role in where we go from here," RBC's chief European macro strategist Peter Schaffrik said.
