LONDON, Oct 19 Some banks are scaling back
forecasts for deeply negative German bond yields that they
issued after Britain's decision to leave the European Union, as
investors reassess the outlook for inflation and central bank
policy, suggesting yields may have bottomed out.
The new forecasts for slightly higher yields than previously
predicted partly reflects a growing expectation that the
European Central Bank will remove a self-imposed floor for its
bond-buying scheme later this year. That would make more bonds
eligible and reduce demand for those now covered by the scheme.
German 10-year bond yields, the benchmark for euro zone
borrowing costs, have risen about 15 basis points this month on
a sell-off in British gilts, higher oil prices, growing
expectations for a year-end rise in U.S. interest rates and
jitters that the ECB may one day wind down quantitative easing.
A key market gauge of long-term euro zone inflation
expectations has rebounded from record lows to
1.44 percent -- still below the ECB's inflation target of just
below 2 percent, but its highest level since early June.
Germany's Bund yield is at 0.02 percent, up
from a record low of minus 0.20 percent in July, when fears
about the fallout from Britain's decision to quit the EU boosted
demand for safe-haven German debt.
But with bond yields globally on the rise, a number of banks
have changed their forecasts in recent days, in perhaps another
sign that a 35-year bull run in government bond markets is
Rabobank, which after the Brexit vote forecast Bund yields
would fall low as minus 0.3 percent, now expects them to end
2016 at 0.1 percent, up from a previous estimate of zero
"We've had clients say to us we're out on a limb now as
everyone else becomes more bearish on bonds," said Richard
McGuire, head of rates strategy at Rabobank. "We're still
bullish long-term, as the outlook for global growth remains
fragile, but there are a number of headwinds right now."
Both Mizuho and DZ Bank forecast 10-year German yields to
end the year around zero percent, up from previous estimates
that put them in negative territory.
Societe Generale, which changed its forecasts in late
September, sees Bund yields ending the year at minus 0.10
percent from a previous estimate of minus 0.25 percent, grinding
higher next year.
In a note released after the June 23 Brexit referendum,
SocGen put the range for German Bund yields at minus 0.25
percent to minus 0.45 percent.
The median forecast by analysts polled by Reuters in
September is for Bund yields to end the year at zero percent. reuters://realtime/verb=Open/url=cpurl://apps.cp./Apps/mm-bondyield-polls?s=AL&st=G
Steven Major, global head of rates strategy at HSBC, who
correctly called the steep fall in global bond yields in recent
years, said this month that yields will remain at current
historical lows for another five years.
For some analysts, a reason to forecast slightly higher
yields is a view that the ECB will remove the deposit-floor rule
for its asset-purchase programme when it announces tweaks to the
scheme later this year.
Removing the self-imposed rule that the ECB can only buy
government bonds with a yield below the bank's deposit rate
would increase the pool of eligible bonds for QE and reduce
downward pressure on yields. Speculation about such a move has
also started to move money market rates.
"We were not previously pricing in the ECB buying bonds
below the deposit rate," said Peter Chatwell, head of European
rates strategy, at Japanese bank Mizuho.
"The chances of that have increased and that means we have
to look at the shape of the yield curve, which would steepen,"
he said, adding that Bund yield could rise to 0.2 percent over
the next month.
