London close: Gains erased as Cyprus puts bank levy back on the table

Stocks trimmed gains on Friday afternoon on the back of ongoing developments in Cyprus as politicians desperately scramble to come up with a 'Plan B' to raise the funds needed to secure financial assistance from the Troika.Nevertheless, markets maintained their positive bias on hopes that a deal can eventually be made."Given the uncertain headlines continuing to come out of Cyprus, Europe's markets have remained remarkably resilient to the swirling cross winds of news flow coming out of the beleaguered country," said Senior Market Analyst Michael Hewson from CMC Markets."Whispers of possible deals in the next few hours has helped buoy sentiment heading into the weekend, however history has taught us throughout this crisis it would be premature to break out the bunting and champagne quite yet. As with a lot of the optimism that emanates from the euro area the champagne soon ends up going rather flat."Gains were trimmed in afternoon trade after Cypriot Finance Minister Michalis Sarris confirmed that Cyprus is considering bringing back the plan to tax customer accounts despite the controversy that it has stirred earlier this week.Sarris was quoted as saying: "I think that is clearly on the table, that is something that needs to be discussed to see whether a levy on deposits of some sort [...] would make a contribution to finalising the package."Also pressuring stocks late on were reports that the Troika has increased the amount it wants Cyprus to raise from €5.8bn to €6.7bn.
