Back to basics
Ask some Canadian plan sponsors about the value that bonds add
to a pension portfolio and you might get the following response:
“Bond managers don’t add much value, so there’s
not much to be gained by paying attention to that part of our portfolio.
Besides, I glaze over with all the technical detail of bonds. The
fixed income allocation of my investment portfolio is there to hedge
liabilities anyway, so we are better off focusing on alternative
investments and equities to add value.”
But this is wrong. It is true that many top-quartile domestic bond
managers add only about 30 basis points (bps) over their benchmarks,
leaving even less net of fees. However, they leave money on the
table because they ignore opportunities to add value through more
innovative fixed income strategies. Foreign pension plans have long
recognized the value of accessing global bonds and credit strategies
on a tactical basis, reaping alpha rewards well over 100 bps versus
domestic benchmarks with a similar risk profile. Fees may be slightly
higher for some of these strategies, but a net addition of 70 bps
for a $500 million-dollar fixed income portfolio adds up to $3.5
million every year. This extra return potential is well worth the
investment of some time and effort to learn more about the opportunities
and understand the risks.
The fixed income world is indeed technical, and many sectors require
specialized expertise to find profitable trading and investment
opportunities and to skillfully monitor and manage risk. Plan sponsors
have much to gain from becoming educated consumers of this sector
and investigating new strategies to add value in this significant
portion of their portfolio. To help them along the way, this section
of the Fixed Income Primer
will outline the latest trends and topics in domestic bonds and
some of the more complex foreign fixed income securities.
Key Terms
Government of Canada Bonds – The government
regularly issues money market, 2- 5- 10- and 30-year bonds in the
public market through an auction process. Fiscal surpluses have
eliminated the need for net new financing, but maintaining a liquid
government market across the yield curve is important for financial
market health and future market access. To support the size and
liquidity of new benchmark issues, the government began buying back
less liquid bonds by reverse auction. The Government of Canada is
currently reviewing how they will issue bonds and continue to maintain
a liquid bond and money market.
Federal Agency Bonds – In Canada, these
are bonds issued by agencies and they are fully guaranteed by the
Government of Canada. Examples are Canada Mortgage and Housing Corporation
(CMHC), Farm Credit Corporation, and Export Development Corporation.
Despite the full guarantee, these bonds have higher yields than
Canadas, so the government is considering rolling these debt programs
into general funding. Canada Mortgage Bonds (CMB) are a new category
of Federal Agency bonds and make up the bulk of this issuance. The
CMB program began in 2001 and consists of five-year bonds issued
by the Canada Mortgage Trust, which holds residential mortgages
issued by banks and other financial institutions as backing assets.
These bonds are fully guaranteed by the Government of Canada and,
from an investor perspective, are large semi-annual coupon bonds
with no prepayment risk (that risk is retained by the originating
banks). They yield about 13 bps higher than Government of Canada
bonds for the same AAA credit quality and similar liquidity. This
market has limited the issuance of other prepayable mortgage-backed
securities in Canada. Overweighting these bonds is an easy, low-risk
way to add value.
Provincial Bonds and Guarantees – The biggest
provincial issuers are Ontario and Quebec, which make up nearly
70% of the provincial market, and are the only issuers with significant
issuance of long-term bonds. There is some disagreement about how
“quasi-provincial” issuers without guarantees, such
as school boards, should be classified for Index purposes. Provincial
spreads are tight and relatively stable, driven primarily by overall
credit market fundamentals and liquidity, with minimal differentiation
by province, particularly since political risk in Quebec has subsided.
Active strategies within provincials have limited value added capacity.
Municipal Bonds – Municipal bonds (munis)
are under 2% of the Index in Canada. Many municipalities now combine
forces and issue debt through trusts for cheaper funding with greater
liquidity. The B.C. municipal finance authority has a higher rating
than the province, while others are guaranteed by their province
to improve their ratings. Many munis are issued as serial bonds,
whereby a series of maturities, each with a small amount outstanding,
are issued simultaneously. The small individual issue size limits
liquidity and usually excludes these from bond indexes. Yield spreads
on munis are correlated with provincial spreads, and opportunities
for active strategies are limited.
Corporate Bonds – In Canada, corporate
bonds have grown from about 10% of the market in 1990 to nearly
30% as government issuance has shrunk and investors have become
more receptive to corporate credit to add yield to their portfolios.
Diversification in this sector is still poor, with financials representing
a full 48% of the market, made up of only a handful of bank and
insurance issuers along with a few financing companies. The long
end is also poorly diversified, dominated by a few major non-financial
issuers such as Trans Canada Pipelines, GTAA, Bell, and Enbridge.
The BBB sector has expanded to 4% of the market (mainly under 10
years), but is still small in Canada.
Canadian pension plans are increasingly allowing BBBrated bonds
since corporate credit analysis by money managers has improved.
This trend has contributed to tight credit spreads in all global
markets. Many managers follow a simple strategy of overweighting
short-term corporate securities since spread volatility in that
sector is relatively limited and investment grade default rates
are very low. But this strategy can backfire in severe credit environments,
as was the case in 2001. Maple Bonds – Maples are foreign
(corporate or sovereign) bonds issued in the Canadian market, in
Canadian dollars. Approximately half of new corporate issuance in
Canada in 2006 has been Maple bonds, a major trend since the removal
of the Foreign Property Rule. These bonds eliminate foreign interest
rate and currency risk and offer some credit diversification versus
domestic issuers. So far, however, high-quality financial issuers
dominate Maples. Manager understanding and monitoring of foreign
credit risk are essential despite the fact that most of these issuers
are highly rated. Secondary market liquidity can be a concern since
only the lead dealer supports some deals, with little or no syndicate
participation. Other concerns include extra custodial fees for bonds
not settled by Canadian Depository Services (CDS), and legal structure
since many deals are private placements and investors are subject
to a foreign jurisdiction in the event of default.
Foreign Investment Grade Credit – Foreign
currency and interest rate risk, but this sector offers much better
diversification. Manager expertise in credit and derivatives markets
is important, and some players can effectively translate their domestic
experience into foreign markets. One surmountable barrier to managing
currency and interest rate risk through asset swaps or other strategies,
is that pension plans must implement a derivatives policy and International
Swaps and Derivatives Association (ISDA) agreements.
High Yield – The junk bond market started
in the 1980’s and has evolved into a large, liquid marketplace
with over 1600 issues and nearly $600 billion outstanding in the
U.S. alone. That is about the same size as the entire Canadian bond
market. Typical U.S. pension plan allocations remain modest, with
hedge funds being the most active players. Some Canadian plans are
strategically active in the speculative market. The best risk and
reward tends to be in the BB-rated sector.
Mortgage-backed Securities (MBS) – These
are pools of mortgages whose payments are securitized in a trust
structure and passed through to bond investors. They usually have
monthly coupons and most have prepayment risk. The AAA rating comes
from guarantees by CMHC in Canada (i.e. the Federal Government)
or Ginnie Mae or Fannie Mae in the U.S. (private agencies, not government-guaranteed).
The U.S. MBS market is 20% of the global bond market and is bigger
than U.S. Treasuries, so U.S. MBS are highly liquid. The behaviour
of this market and hedging by major mortgage players is well recognized
as a driver of bond market movements, but specialized expertise
is required to successfully invest in MBS on a tactical basis. Prepayable
MBS effectively allow managers to bet on interest rate volatility,
which is the main driver of relative value in this market and is
a diversifying exposure for Canadian bond portfolios. This market
can be an excellent substitute for expensive Canadian corporate
bonds, with comparable yields for higher-quality credit. However,
it may not be attractive in some environments once currency hedging
is taken into account.
Credit Default Swaps (CDS) – CDS are like
an insurance policy where the buyer of default protection pays a
premium, and receives a specified notional value in the event of
default of the reference asset (usually corporate bonds or loans).
Alan White’s article on page 37 provides a detailed description.
These liquid contracts isolate credit or spread risk, with no interest
rate risk. Currency risk is minimal, or can be eliminated cheaply
if CDS is denominated in Canadian dollars. In Canada, relatively
few large Canadian names are actively traded, with the majority
of trades being in global ones. The benefit of this sector for Canadian
portfolios comes from the diversification, liquidity, and the pure
credit play with limited currency exposure.
Structured Finance – This category includes
assetbacked securities (ABS), commercial mortgage-backed securities
(CMBS), and collateralized debt obligations (CDOs). Portfolios of
fixed income assets, pooled in a trust structure, are tranched into
pieces (senior, mezzanine, and equity which bears the first to default
risk), with varying levels of protection from default of the underlying
assets. Some structures have enhancements to improve credit ratings,
such as overcollateralization. Each tranche is rated AAA and below.
Underlying assets may include credit card or loan receivables (ABS),
commercial mortgages (CMBS, where mortgages are not federally guaranteed),
bonds (CBOs), loans (CLSs), and/or credit default swaps (synthetic
CDOs), and other assets, ABS, and CDOs made of CDOs (CDOsquared).
ABS are the simplest structures, but other structured finance investments
require specific expertise, especially when investing in lower-rated
tranches. Structured finance markets are growing in Canada and globally.
Investors must carefully assess the risk and diversification of
underlying assets. Ratings depend on quantitative modelling and
simplifying assumptions. The CDO market was tested in 2000 and 2001
with high yield bond defaults, and structures were strengthened,
but model risk remains relatively untested.
Global Government Bonds and Related Derivatives
– Duration and yield curve strategies can be expanded into
global government markets by domestic or global managers. Limiting
managers to a long-only approach restricts relative value strategies
to those where the foreign market is expected to outperform Canada.
Allowing short positions boosts potential returns without necessarily
increasing risk. Derivatives such as futures and swaps can also
be used to implement these strategies, freeing up cash for other
value added strategies, such as enhanced money market (a relatively
low-risk, yield-enhancing strategy investing in very short-term
credit, or extending to six to 18 month maturities to take advantage
of an upward-sloping yield curve). Implementation of these strategies
is straightforward and can be done well by small teams. In addition
to evaluating a manager’s expertise and experience in these
markets, plan sponsors should inquire about the manager’s
tools for monitoring the risks of short positions or derivatives.
Emerging Markets – This sector includes
most markets outside the G10 countries. The credit quality of many
issuers has improved dramatically in the past few years as major
issuers like Russia and Mexico and others are now investment grade.
Contagion among markets has also decreased, which enhances diversification
benefits. Corporate issuance is expanding rapidly as government
supply dwindles. Most bonds are traded in U.S. dollars, but increasing
issuance of local currency debt raises the spectre of managing the
currency risk, which may be difficult in some markets. Spreads in
emerging market debt have tightened in recent years along with all
credit markets, but opportunities remain due to improving credit
quality.
Strips – Bonds can be stripped into coupons
and residuals (the par amount due at maturity). Each piece is then
traded as a separate security. The strips can be reconstituted into
bonds at any time. As long as a coupon has the same date (e.g. June
1st), it can be used to reconstitute any bond from the same issuer
with that same coupon date. A strip has much more interest rate
risk (longer duration) than a bond of similar maturity. Convexity
risk, or sensitivity to the shape of the curve, differs from bonds.
In Canada, only a handful (10 or so out of nearly 600 securities)
of strips trade actively. The remaining ones tend to be purchased
and held long-term to directly hedge liabilities.
Inflation-linked bonds – Linkers, or real
return bonds, have a coupon and principal that increase with inflation
and earn a real yield that protects purchasing power. Prices of
inflation-linked bonds reflect investor opinions about the direction
and magnitude of inflation, but in Canada’s small, illiquid
market, the relative value is also subject to severe market demand
forces. The Canadian market is limited to only four Government of
Canada issues, all in the long end, and a few provincials. That
is small compared to the U.S. and the U.K., where these bonds are
issued with a wide range of maturities and trade more actively.

FIXED INCOME FUNDAMENTALS & STRATEGIES
Price/yield relationship
As yields, or interest rates, rise, the price of
a bond falls. For a simple pure discount bond, this formula
shows the relationship between price and yield.
| Price = |
FaceValue |
| |
(1 + yield)T |
Yield curve
The relationship between Government of Canada bond yields
and maturity.The yield curve is usually upward sloping, so
rates are generally higher for longer maturity bonds.This
makes the “carry trade” possible, where investors
can borrow short-term and invest long-term and make a profit
as long as rates don’t rise too much.
In Canada the difference between 2-year and 30-year rates
has averaged about 150 bps (or 1.5%) over the past 10 years.This
is currently only a few bps, and so the curve is flat. An
“inverted” yield curve means short rates are higher
than long rates, which usually signals a recession and does
not last very long.
Duration
Sensitivity (% change) of a bond’s price to changes
in yield. A bond with nine years to maturity has a duration
of about 6.4 years (which is the Canadian Index duration).
When rates rise by 1%, the bond’s price will fall by
6%. Longer duration bonds outperform as rates fall. Duration
can also be defined as a weighted average time until cash
flows are received. Duration measures sensitivity to parallel
yield curve movements.
Longer-term bonds have longer duration. For the same maturity,
lower coupons mean longer duration.This is illustrated in
Chart 1, on page 25. For strips, duration and term to maturity
are the same. For callable bonds, “optionadjusted”
duration is the relevant measure, which accounts for changes
in the value of the option to call the bond when rates move
in various ways.
Yield curve steepener/flattener
A steepener is a trade that pays off if the yield curve steepens.
It can involve selling, or underweighting, long-term bonds
and buying, or overweighting, short-term bonds.This trade
is usually implemented duration neutral so that it pays off
as long as the curve steepens, no matter what happens to the
level of interest rates. A bullet usually has a steepening
bias.
A flattener pays off if the yield curve flattens, i.e. if
short rates rise relative to long rates, or if long yields
fall more than short-term rates. Sell short bonds, buy long
bonds to implement. A barbell usually has a flattening bias,
but can be a negative carry trade (one that gives up running
yield) when the yield curve is very steep. If managers are
wrong about the timing of a flatter curve, and have to wait
too long, they can underperform even if their view is correct.
Bullet/barbell
A bulleted portfolio is overweight the belly (mid-term 5-
to 10-year maturities) vs. the benchmark, and underweight
the wings (short and long maturities).This portfolio generally
outperforms if the curve steepens (short rates fall and long
rates rise, or both rise but the short end goes up less etc.).
A barbelled portfolio is overweight the wings, and underweight
the belly.This generally outperforms if the yield curve flattens,
but depends on the specific holdings in the short end and
the exact change in the curve shape.
Credit spread
The difference between the yield on a non-Government of Canada
bond and a Government of Canada bond with similar term to
maturity or duration.The decision to invest in provincials
or corporates is driven by the view of whether spreads are
expected to tighten or widen.
When credit spreads widen, corporate bond yields go up relative
to Canadas, so corporates underperform government bonds. When
credit spreads tighten, corporates outperform governments.
Sector allocation
The decision to over or underweight specific sectors (such
as Provincials, Corporates) vs. the benchmark. If managers
believe corporate bonds will outperform, so corporate spreads
will tighten, they will overweight corporate bonds vs. the
benchmark, and/or select corporate bonds with longer duration
(which will have greater sensitivity to spread movement) than
the benchmark.
