Bank shares rally on hopes of eurozone debt deal

European bank shares have risen as investors react to the latest attempts to stabilise the eurozone debt crisis.

A number of measures are being discussed according to reports from the weekend's international meeting in Washington.

They are expected to involve a 50% write-down of Greece's massive government debt, the BBC's business editor Robert Peston says.

French and German bank shares were up 10% at one stage in Monday trading.

European governments hope to have measures agreed in five to six weeks, in time for a meeting of the leaders of the G20 group in Cannes at the beginning of November.

But EU officials in Brussels stress that they should not be seen as "a single grand plan", the BBC's correspondent Chris Morris says.

The measures being discussed are:

Institutions that have lent money to Athens writing off about 50% of the money they are owed
The size of the eurozone bailout fund, the European Financial Stability Facility (EFSF), increasing dramatically to 2 trillion euros (£1.7tn; $2.7tn)
Strengthening big European banks that could be hit by any defaults on national debt obligations.

However, on Monday evening AFP reported that German Finance Minister Wolfgang Schaeuble had told television news channel NTV that there was no plan to boost the size of the EFSF.

"We are giving it the tools so it can work if necessary," Mr Schaeuble was reported as saying.

"Then we will use it effectively but we do not have the intention of boosting its volume."Pan-Europe gains

Uncertainty over how to tackle Greece's problems has led to some European bank shares losing half their value in recent months due to concerns about their holdings of Greek debt.

But on Monday, French banks, which are particularly exposed to Greece, rallied, with BNP Paribas and Societe Generale up 4% and 5.4% respectively, and Credit Agricole up 3.7%.
