MILAN, Jan 18 Shares in Italy's leading banks
plummeted on Monday, bringing their losses to 17 percent for the
year so far, with brokers warning the negative tone is set to
continue after a stellar performance in 2015.
Investors are nervous about how the sector will cope with
lower interest rates and a 200 billion euro ($218 billion) pile
of loans that are unlikely to be repaid.
Those concerns are trumping expectations about a wave of
consolidation likely to sweep the sector, with cooperative banks
under pressure to merge following a government reform to reduce
the number of lenders.
On Monday, Italy's banking index fell 5.7
percent with Monte dei Paschi di Siena the biggest
loser with a 14.8 percent drop.
The slump, which also hurt the bank's riskier junior debt
, prompted Italian market regulator Consob to
introduce a temporary ban on short-selling.
Monte dei Paschi CEO Fabrizio Viola said in a statement on
Monday the bank was financially sound and the share drop
Italy's oldest bank, the only Italian lender to be bailed
out during the financial crisis, is saddled with problematic
loans equal to more than a fifth of its total client loans.
JP Morgan said this month Italian banks should be avoided
because low interest rates are expected to put pressure on
revenues more than in other countries and credit problems limit
a recovery in provisions.
Traders have suggested exiting investments that have been
particularly favoured, such as Popolare di Milano and
Intesa, as the stocks have reached key support levels.
"I think upside on cooperative banks this year is much more
limited," said a London-based equity sales person.
A government reform of Italy's top 10 cooperative banks
forces them to turn into joint-stock companies by year-end,
making them potential takeover targets.
Talks among the main players -- UBI, Popolare di
Milano and Banco Popolare -- about defensive mergers
are under way.
Analysts say stimulus measures by the European Central Bank
have helped an economic recovery but have the side effect of
putting bank margins under pressure. They say more turbulence is
to expect in their stocks as markets are being rattled by woes
over China and the oil prices.
But some fund managers maintain their positive bets on a
sector where valuations are in some cases below rivals elsewhere
"I would look at calls to exit Italian banks with a pinch of
salt," Gilles Guibout, portfolio manager at AXA IM, said.
"Consolidation has not yet happened but it will and then
allow market repair and bring in efficiencies."
