Italy’s finance minister, Pier Carlo Padoan, wants to “ringfence” its troubled banks.

Padoan called for a meeting of executive of the troubled banks in Rome on Monday. The banks allegedly will come up with a “Last Resort” bailout fund.

Last resort or first resort, is there a difference at this point in time?

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.

The plan being worked on, which could be officially announced as soon as Monday evening, recalls the Sareb bad bank created in 2012 by the Spanish government to deal with financial crisis in its smaller cajas banks, say people involved.

Although the details remain under discussion, it foresees the establishment of a private vehicle that will include upwards of €5bn in equity contributions — mostly from Italy’s banks, insurers and asset managers — and then a larger debt component. The fund will then mop up shares in distressed lenders.

A second vehicle will seek to buy non-performing loans at market prices.

“It is a backstop fund,” said one person involved in the talks.

The Italian government can provide only limited financial backing because of EU state aid rules and because it is already struggling under a public debt load that amounts to 132.5 per cent of GDP.

People involved in the talks question whether the plan would have the financial scope to provide a buffer of last resort for Monte dei Paschi di Siena. Italy’s third-largest bank was the worst performer in the 2014 European stress tests, with about €170bn in assets and about €50bn in bad loans. It is considered by many bankers to be the major risk to Italian financial stability and regarded as too big to fail.

“Monte Paschi is the elephant in the room,” says one of Italy’s top bankers.

Monte Paschi is already trading at zero compared with its tangible equity value if its bad debt disposal is taken into account at current prices, says Johan De Mulder of Bernstein Research. By comparison, when Lehman Brothers collapsed in 2008 it was trading at about 20 per cent of its tangible equity.

Berenberg analyst Eion Mullany argued that the “Italian banking sector is at a pivotal moment in its history”.

“We worry that a bail-in of an Italian bank may cause a chain reaction with ripple effects felt across the European banking system,” Mr Mullany added, referring to the possibility of bondholders and depositors in Italian banks being forced to participate in a rescue.
