Just as it is for
any fixed-income security, inflation is a risk for stable value funds.
Over the long term, it erodes the purchasing power of underlying investments,
whether those are traditional guaranteed investment contracts (GICs)
or bond portfolios backed by insurance wrappers. In the near-term, inflation
fears can cause interest rates to rise and reduce the market value of
those investments.
Lately, inflation
has been on the upswing. The Consumer Price Index rose 2.7 percent in
2004, up from 2.3 percent in 2003 and 1.6 percent in 2002. It continued
to climb through the first four months of this year, hitting an annualized
rate of 3.5 percent by April, before backtracking to an annualized rate
of 2.8 percent in May.
Fortunately, stable
value managers are able to tap a broad and growing array of tools and
strategies to mitigate the impact of rising inflation on their portfolios,
including inflation linked bonds and inflation derivatives. To guard
against increased interest rates brought about by inflationary fears,
managers also can reduce portfolio durations by purchasing shorter maturity
or floating-rate securities.
The market for inflation
linked securities in the U.S. began in 1997, when the U.S. government
began issuing Treasury Inflation-Protected Securities, or TIPS, which
receive principal adjustments linked to movements in the U.S. Consumer
Price Index, a popular measure of inflation. This market has expanded
rapidly and now include securities worth more than $225 billion. As
the TIPS market has expanded, other corporate, agency and municipal
issuers have piggybacked on the investor demand for inflation-linked
fixed income securities. Most recently, Aegon Institutional Markets
late last year began selling "Inflation GICs," or "I-GICs," whose returns
also are linked to the Consumer Price Index.
Which inflation
hedges a stable value manager uses depends in part on the way his portfolio
is invested. Alliance Capital, for example, exclusively manages wrapped
bond portfolios, and it periodically invests in TIPS. "We use them opportunistically,"
says Greg Wilensky, Director of Stable Value Investments for Alliance
Capital, "meaning we use them when the breakeven inflation rate--the
difference in yield between a TIPS and a comparable maturity conventional
Treasury-is below our longer term inflation forecast. We also have discussed
using TIPS on a strategic basis-that is, adding them to the account
benchmark-with some stable value clients and prospects."
Stable value manager
Fiduciary Capital Management, by contrast, invests about 80 percent
of its stable value portfolios in GICs and doesn't include TIPS in its
portfolio. However, David Molin, Vice President and Director of Research
for FCM, says the firm did buy a five-year Inflation GIC in January
after comparing it to alternative investments, including TIPS, inflation-linked
AA-rated corporate bonds and traditional fixed-rate GICs. At the time,
the I-GIC's initial crediting rate of 4.53 percent was about 10 basis
points higher than the yield on a five-year TIPS and 36 basis points
higher than the yield on a comparable fixed-rate GIC, he says. By early
June, the crediting rate was still about 10 basis points over a fixed-rate
GIC. He says FCM calculates that the I-GIC will prove to be a better
investment than a fixed-rate GIC if, over its five-year life, the CPI
rises by an average of 3.10 percent or more annually. "With oil prices
going up, we felt this would be a good hedge against any inflation scenario,
including a potential oil crisis," Molin says.
I-GICs are built
on a traditional floating-rate GIC platform. Their monthly interest
payments are linked to year-over-year changes in the Consumer Price
Index plus a fixed spread established at the contract's inception. For
example, if the inflation rate based on the year-over-year percent change
in the CPI was 3.5 percent at the time a contract was sold, and the
spread was 100 basis points, the initial crediting rate would be 4.5
percent. Because of the seasonal factors and the spikes and troughs
common in the CPI, the initial crediting rate on an I-GIC as with other
floating-rate securities, may not be the best indication of the expected
yield over the life of the security.
Pluses and Minuses
While all of the inflation-protection tools available to stable value
managers can help them manage inflation risk, each does so with a different
mix of benefits and drawbacks. Floating-rate GICs, for example, do not
provide the same direct hedge against inflation that I-GICs, TIPS or
other inflation-linked securities provide, since their crediting rate
is pegged to an interest rate, such as LIBOR, rather than inflation-and
sometimes, interest rates are impacted by market factors other than
inflation.
TIPS do offer a
direct hedge against inflation, but differ from I-GICS and most other
recently issued inflation-linked bonds in a variety of ways, including
their underlying mechanics. As noted earlier, with TIPS, it is the principal
of the bond that gets adjusted for inflation, while the coupon stays
the same. With I-GICs, it is the crediting rate that gets adjusted.
TIPS pay interest semi-annually, while I-GICs pay interest monthly.
There is an active secondary market for TIPS, while no such market exists
for I-GICs. Both inflation-linked securities issued by corporations
and agencies and I-GICs provide opportunities for higher yields, albeit
with higher credit risk, than do Treasury-issued TIPS, which are AAA-rated
government-backed securities.
Aruna Hobbs, Head
of the Pensions and Savings Group at Aegon, argues that one of the primary
benefits of hedging inflation risk with I-GICs is the opportunity to
diversify an investment portfolio while also capturing what has been
a fairly high initial crediting rate-about 4.7 percent in late May.
Back then, that was roughly in line with the crediting rate available
on traditional GICs of the same maturity. I-GICs, like other inflation-linked
securities, also offer portfolio diversification benefits to stable
value managers. Thanks to their built-in inflation hedge, they offer
low or even negative return correlations with bonds and many other asset
classes.
Hobbs says the spread
available to I-GIC investors at any given time will vary depending upon
market conditions. Generally, the spread will be smaller when inflation
expectations are high, and larger when inflation expectations are low.
Early this year, the spread was hovering around 100 to 120 basis points.
Hobbs says she expects
buyers of I-GICs to be plan sponsors and their intermediaries, including
pooled funds, that traditionally purchase guaranteed investment contracts
and are looking for inflation hedges or yield enhancements. They also
may appeal to stable value funds that invest in medium-term notes. By
May 2005, the firm had already sold five contracts and was nearing completion
of a sixth deal. Although Aegon was the only institution selling I-GICs
early this year, Hobbs recognizes that additional players may enter
the market. In fact, she says, "We are hopeful that there is going to
be a lot of demand and that this will encourage people to institutionalize
the product. When it starts to become more mainstream, there will be
a natural need for more providers."
With the growing
array of hedging tools available to them, stable value managers may
not be able to ignore inflation risk, but they can manage it.
