LONDON, Dec 21 Spanish government bond yields
hit five-week lows on Wednesday as the sometimes toxic link
between sovereign debt and the banking sector in the lower-rated
countries of the euro zone weighed on debt markets.
Concern over whether troubled Italian lender Monte dei
Paschi would be able to raise the 5 billion euros ($5.2
billion)it needs to avert being wound down initially saw
investors pull money out of Italian government bonds and into
similarly-rated Spanish debt.
The gap between yields on Spanish and Italian 10-year debt
nudged back above 50 basis points (bps), a level last breached
in the days after a failed constitutional reform vote triggered
the resignation of Italian Prime Minister Matteo Renzi.
Italy's parliament later approved a government request to
borrow up to 20 billion euros to underwrite its fragile banks,
easing investors' immediate worries.
Strategists at ING said the combination of possible snap
elections next year and higher bond issuance to prop up Italy's
ailing banks "arguably make for a dangerous cocktail" for
Italian bonds in 2017.
However, Spanish banks also took a hit on Wednesday from a
European Court of Justice ruling that will require them to repay
mortgage customers more than 4 billion euros.
By 1630 GMT, Spanish 10-year yields stood at
1.36 percent, up 2.5 basis points on the day, having fallen as
far as 1.31 percent, their lowest since Nov. 10, earlier in the
"The only fundamental I can see behind this is the news
about the banks," Mizuho strategist Peter Chatwell said.
Italian 10-year yields fell 1.6 bps to 1.83
percent, narrowing the spread between the two to 47 bps.
Another key event for Italy's banks will come on Jan. 13,
when ratings agency DBRS will decide whether to downgrade the
country in a move that could increase costs for its lenders.
DBRS's co-head of sovereign ratings and chief economist
Fergus McCormick told Reuters the next 24 hours, how the
problems at Monte dei Paschi were addressed and whether a plan
was drawn up to shore up the banks would be crucial for the
A downgrade would mean banks would have to stump up more
collateral for European Central Bank funding.
Shares in Monte dei Paschi closed down 12 percent
after falling as much as 19 percent in very volatile trade.
Two sources close to the matter said the bank had been
unable to find an anchor investor willing to put money in its
privately funded rescue plan.
The worst performing share on the pan-European STOXX 600
index, of which Monte dei Paschi is not a constituent, was
Spain's Banco Popular.
Ten-year yields on bonds of the higher-rated euro zone
members fell 1-2 bps on the day. German Bund yields, the
benchmark for borrowing costs in the bloc, fell 1.9 bps to 0.25
