MILAN, June 22 (Reuters) - Britain's top share index rebounded on Friday to post a weekly gain as oil majors got a boost from an OPEC deal to modestly raise output, helping to soothe fears over a trade war and the revived prospect of an interest rate hike in August.
The FTSE 100 .FTSE ended the day up 1.7 percent, a rise which allowed it to finish on a weekly gain of 0.6 percent and avoid a fifth straight week of losses.
Heavyweights BP BP.L and Royal Dutch Shell RDSa.L rose 3 percent and 3.3 percent respectively as oil prices jumped more than 4 percent after major producers agreed to modest crude output increases to compensate for losses in production at a time of rising global demand. rise in oil prices might however only give a temporary respite to investors.
"Trade tensions remain the dominant theme, clarity still lacking about how far things will ultimately go between U.S. and China, and the potential ripple effect for world trade," said Mike van Dulken and Artjom Hatsaturjants at Accendo Markets.
