Italy is rushing to cobble together an industry-led rescue to address mounting concerns over the solidity of a banking sector whose woes pose a risk to the wider eurozone economy.

Finance minister Pier Carlo Padoan has called a meeting in Rome on Monday with executives from Italy's largest financial institutions to agree final details of a "last resort" bailout plan.

Yet on the eve of that gathering, concerns remain as to whether the plan will be sufficient to ringfence the weakest of Italy's large banks, Monte dei Paschi di Siena, from contagion, according to people involved in the talks.

Italian bank shares have lost almost half their value so far this year amid investor worries over a €360bn pile of non-performing loans — equivalent to about a fifth of GDP. Lenders' profitability has been hit by a crippling three-year recession.
