(Adds Portugal Telecom also likely to be sued)

LISBON, July 17 Banco Espirito Santo (BES) could
be sued over a loan that one of its founding family's holding
companies failed to repay to Portugal Telecom, sources said on
Thursday, as credit rating agencies downgraded the bank and its
Still, Finance Minister Maria Luis Albuquerque said the
problems faced by BES, Portugal's largest listed bank,
and the family's Espirito Santo Group did not pose an imminent
danger to the country's financial system and reiterated the
government did not plan to use public funds to help the bank.
But other risks loomed for BES following Tuesday's failure
by the family's Rioforte company to repay 847 million euros
($1.15 billion) in debt to Portugal Telecom, which
forced the telecom firm to take a cut in its stake of a merger
with Brazil's Oi.
Sources close to the process told Reuters that Portugal
Telecom was considering taking BES to court due to the
non-payment as the commercial paper was bought with funds
deposited at BES bank accounts, and was considered risk-free by
the telecom firm.
A BES spokesman pointed to the bank's July 10 statement in
which it said institutional clients "are considered qualified
investors, in accordance with applicable legal criteria, hence
with more capacity to assess risk".
Portugal Telecom declined to comment.
The company also faces a possible lawsuit by several
minority shareholders, according to Diario Economico newspaper.
It cited Octavio Viana, the head of ATM investor association, as
saying they sought legal action against PT's board over the
Rioforte investment that cut their stake in the merged company.
A lawsuit against BES could potentially open the door to
other companies and investors suing it for selling them debts
issued by the family's companies that were seen as being safe.
BES's shares have been hammered by fears in the past few
weeks that its capital base could be undermined by the large
debts of its founding family, which controlled and managed the
bank until just a few weeks ago.
Ratings agencies warned of a potential impact on BES
solvency from the Espirito Santo family's financial problems.
Standard & Poor's cut two notches from its long-term rating
- to high-risk "B-" - for BES, saying its action reflected "our
assessment that BES' capital position has weakened as a result
of the higher losses that, according to our expectations, it is
likely to face given its direct exposure to the Espirito Santo
Financial Group (ESFG), to its subsidiaries, and to Rioforte."
The rating could be downgraded again, S&P said.
Sources have told Reuters that Rioforte is preparing to file
for creditor protection in Luxembourg, where it is registered,
to avoid a disorderly cut-price sale of its assets.
Moody's rating agency - which last week cut BES by three
notches to "B3" - downgraded ESFG by two notches to "Ca", citing
"the heightened risk of default for the group, combined with the
potential for significant losses for bondholders".
ESFG is still the largest single shareholder in BES, with a
20 percent stake.
BES shares fell 7.9 percent to close at 0.419 euros, but
still above the all-time low of 0.36 euros it hit on Tuesday.
"The rating cut is another blow in what has been a very
negative news flow about the group, which stokes the uncertainty
in the market, not allowing BES to have two straight sessions of
gains," said Jose Novo, a trader at Orey iTrade brokers.
Shares in Portugal Telecom fell 6.8 percent to new all-time
lows after another rater, Fitch, downgraded its and Oi's credit
ratings by one notch to junk-level "BB+" due to the nonpayment
by Rioforte, adding that "the recovery value is highly
uncertain". Oi was down 5.5 percent in Sao Paulo.
Concerns surrounding the Espirito Santo banking clan, which
founded BES more than a century ago, were sparked when an audit
of a family holding company that owns Rioforte found what it
called a "serious financial situation".
Those jitters spread last week to Europe and beyond, raising
broader concerns about Portugal itself, just two months after it
exited an international bailout deal, but have subsided somewhat
after the government said the bank had enough capital to face
its risks and it would not use public funds to help it.
"We are not preparing any recapitalisation of BES, and there
are no indications that it may become necessary," Albuquerque
told a parliament committee.
"The situation in the financial system has improved
significantly with the reinforcement of capital ratios. Let's
not confuse the whole financial system with one bank; it is
important not to spread unjustified alarm."
The problems at BES initially pushed Portugal's bond yields
higher, but in the past few days the yields have fallen again -
to 3.73 percent on Thursday from Wednesday's 3.76 percent.
S&P said potential new impairments associated with BES's
exposure ESFG and Rioforte "could be of a magnitude at least
offsetting the benefit" from BES's recent capital increase.
BES raised 1.04 billion euros in a capital increase in
May-June. It first reported unspecified "material
irregularities" at Rioforte's parent company Espirito Santo
International in the capital hike prospectus in late May.
BES's problems have wiped out 57 percent of its value in the
past month, despite a 20 percent surge on Wednesday that
analysts attributed to bargain-hunting and reports the bank's
new CEO may bring in new shareholders to reinforce capital.
Bank of Portugal chief Carlos Costa has also said that
although he sees no need for a capital increase at BES, there
were shareholders interested in taking part in a BES capital
increase if any additional capital were needed.
