- Consumers upbeat in US, Germany- Germany adviser says Greek bailout terms should be changed- Greek uncertainty still apparentThe FTSE 100 rallied to close slightly higher on Friday, helped by some positive consumer confidence data in the US and Germany, but gains were limited as the focus continues to be on the Eurozone and the future of Greece within the single-currency region. Helping the mood late on was the final reading of the University of Michigan-Thomson Reuters US consumer sentiment index which was revised higher despite expectations for an unchanged reading. Meanwhile, in Germany, the GfK said that its forward-looking consumer confidence index held steady in June with the consultancy adding that "despite recessionary tendencies in Europe and rising uncertainty from the debt crisis, people see the economy growing."Stocks fell over the lunchtime period as reports emerged of the latest polls in Greece, showing Syriza (the party against the austerity package tied to Greece's bailout) leading with 30% while New Democracy was following close behind with 26%. Pasok has also edged forward to 15.5%, while most of the other parties have registered a fall in their popularity. Peter Bofinger, economist of a member of the group which advises the German government, has said that the terms of Greek bailout should be renegotiated as "they were made under the assumption of a much better cyclical development". He said that this is "very important for both sides, because if you have an uncontrolled exit of Greece, it could lead to a 'Lehman moment' for Europe and that is something that should be avoided at any price."In other news, Italy's Prime Minister Mario Monti has claimed that "Europe could soon see eurobonds". German Chancellor Angela Merkel continues to oppose the measure as it insists that countries must first become fiscally responsible. Monti says that Germany would eventually change its mind.
