LONDON, Sept 3 German government bonds edged
lower on Monday, with investors likely to stay cautious before a
European Central Bank meeting at which expectations are high
that details of a bond buying plan will be fleshed out.
Whether falls in Spanish and Italian bond yields can be
sustained depends on the fine print of the scheme, which is
intended to cut borrowing costs.
ECB President Mario Draghi skipped a weekend meeting of
global central bankers to try to smooth over a deep rift within
the ECB over the proposals.

Thursday, but they've got to give the impression they're willing
to," said ING rate strategist Padhraic Garvey.
"The market is being more realistic as the days go by...so
there shouldn't be too much disappointment."
Deutsche Bank estimates that 180-200 billion euros of ECB

Belgium kicks off a busy week for euro zone bond auctions
with the sale of up to 3.2 billion euros of bonds on Monday.
Austria, Germany and France also come to market this week
September Bund futures were 10 ticks lower at
143.93, having retraced around 60 percent of their losses since
late July, reflecting the uncertainty heading into the ECB
meeting this week.
Trading is likely to remain thin on Monday with U.S. markets
closed for the Labor Day holiday.
"We may be a bit more cautious going into Thursday's
meeting," a trader said. "I don't think we're going to see many

expectations of more monetary stimulus to fuel growth - are also
likely to keep investors cautious.
