Government Bonds: Yield Curve
This strategy looks at the difference between short term
interest rates and long term bond yields to show the
incentive for investors to move out along the yield curve to
longer dated issues.
For comparability, bond market indices have been rebased to
set year-end 1994 at 100. Please note the differences
between charts in the Bonds RouteMap and those for other
RouteMaps. Since income is a major consideration for
investment in bonds, bond market indices are shown as total
return and not in terms of price only.
The bond price index is shown as the thick white line on the
right hand axis. The explanatory variable, the yield curve
uses the left hand axis and is shown as the thin yellow
line. A Best Guess as to its future shape is also
shown on the left hand axis as the thin orange line.
In each chart the bond price index is shown in as the thick
white line on the right hand axis. The main explanatory
variable, the yield curve i.e. ratio of long-term bond yield
to short-term interest rates uses the left hand axis and is
shown as the thin yellow line.
A Best Guess as to the future development of the ratio is
also shown on the left hand axis, as the thin orange line.
Best Guesses suggest what would happen to the yield curve
based on Consensus Forecasts for bond yields and interest
rates.
Generally the ratio of long-term bond yield to short-term
interest rates is low when interest rates are expected to
fall and bond prices expected to rise, and vice versa. Thus,
an upturn in the ratio indicates increasing optimism and a
downturn indicates increasing pessimism. Please note that
the value axis for this ratio, on the left hand scale, has
been inverted, so that movements in the ratio point in the
same direction as any changes in bond prices that they may
indicate.
Owing to the conversion of legacy currencies into Euros,
analysis is provided on a common bond market denominated in
Euros, rather than for individual countries. Historical data
is provided by creating synthetic GDP-weighted time-series
for the component currencies, expressed in the European
Currency Unit.
Traditionally the ratio tended to fluctuate within a
well-defined range, so upturns from a low are cyclical
buying opportunities and downturns from a peak are selling
opportunities. However in the past decade, fluctuations have
been much more extreme as short term rates approach zero, so
historic turning points are no longer useful.
