A
rare sight
Currency overlay has been proven
to reduce risk and enhance return, yet it remains rare. Adrian
Leonard explores UK trustees’ reluctance to adopt an active
currency risk management strategy
Establishing a currency hedging programme to minimise exchange risk
related to foreign bond and equity portfolios is widespread practice
in the US, and growing on the continent. Yet fewer than a dozen
UK pension funds have engaged specialist currency overlay managers
to actively manage their currency risk. Logically, trustees should
not overlook an opportunity to enhance both risk management and
return through a single investment decision. However, although currency
overlay has repeatedly been shown to accomplish both, it has not
yet caught on here.
“The argument for currency overlay from the UK perspective is just
as strong, just as valid, and just as logical as from the US or
any base currency perspective,” says Adrian Lee, founder of Dublin-based
Lee Overlay Partners, an active manager that positions itself primarily
as a value-enhancer, as well as a risk mitigator. “I am at a loss
as to why it hasn’t taken off. It is only a matter of time.” Describing
currency overlay as “a necessary speciality who’s time has come,”
Lee says trustees face three major choices on currency risk which
should be made explicitly, or they will be made implicitly through
inaction. “Not making these choices explicitly is, in itself, a
risky option,” he warns. First is to decide how much strategic currency
exposure is desirable. “If you have 30 per cent international exposure,
you start with 30 per cent currency risk. You have to take it as
part of the deal, but currency overlay unwraps the risk,” he says.

The
second decision is on active versus passive management of that risk
– which may not be clear-cut. “Regardless of the preference, active
management is taking place when a portfolio manager decides to underweight
the US. That is a dollar bet as much as any other.” The third question
is: who makes currency decisions? The equity or asset manager, or
a specialist? “If you allow an equity manager to make currency decisions,
you may receive sub-optimal outcomes,” Mr Lee suggests. Neil Record,
chairman and chief executive of Record Treasury Management, attempts
to distil the reasons for why currency overlay has not taken off
as quickly in the UK as it has elsewhere. “A combination of factors
has held it back, led by peer group benchmarking, which obscures
currency risk,” he says. “Trustees
tend to have the view that you take a risk by diverging from the
peer group. Unfortunately that opinion ignores the fact that the
peer group lost a lot of money in the late 1990s as a result of
the strength of the pound.”
In
recent months index-driven funds moved into the majority, exposing
currency risk, but Bill Muysken, head of global manager research
at WM Mercer Investment Consulting, says it could be a lingering
factor. “Up until ten years ago, a typical UK pension fund was benchmarked
against a peer group, and everybody assumed currency exposure was
unhedged. That has been changing, and the number of large plans
benchmarked against a peer group must be in the minority now. But
even funds with their own specific benchmarks still give some thought
to peer group benchmarks.” Mercer cites two reasons for adopting
a currency overlay strategy, which it says is suitable for funds
with at least £30m invested internationally.
“On
a strategic level, we think it makes sense to have a partially hedged
benchmark for international equities, because it is less risky than
an unhedged benchmark,” Mr Muysken says. “The second reason is that
we think active currency management has good prospects for adding
value. If a pension fund is going to pursue active management in
any way, shape or form, we think active currency management is a
type they ought to consider.” Record says the benefits of currency
management are overwhelming. “If measured against what most funds
are doing now with currency – leaving it unhedged – we can reduce
the volatility and increase the return. It is the only asset allocation
change that can do that.” Any way you cut the analyses, he claims,
currency managers’ aggregate performance record shows that trustees
will reduce risk against sterling-denominated liabilities by hedging
their currency risk, and his own firm, an active manager, has produced
added value across its 18-year history. “We do it by exploiting
the well-known inefficiency known as trends,” he explains.

Others
use different approaches. “We have a reactive, non-forecasting,
model-based approach which we expect to outperform fundamental approaches
over time,” says Kevin Bailey, co-managing director, of BNY Overlay
Associates, part of the Bank of New York. “It is not so much about
managing risk – you do that incidentally. We are of the camp that
believes running a currency overlay programme can add significant
value.” Bob Collie, director of consulting at Frank Russell, says
his company’s work has found that currency managers, as a group,
have performed “reasonably well in most active manager situations,”
and praises the skills of the incumbents. “A lot of participants
in the currency markets have different objectives than them, so
it is easy to see why they can do well.”
However,
unlike Mercer, Frank Russell is not suggesting that all sizeable
UK funds pursue a currency hedging strategy, at least not yet. “Is
this performance something that is just interesting, or is it something
that funds should actually start to exploit?” he asks. “That is
what we are looking into now. We are discussing currency overlay
with some of the largest, most sophisticated funds, but we are a
long way from recommending that all funds should start currency
overlay.” Frank Russell took a more bullish stance a year ago, when,
along with Mercer, Bacon & Woodrow, and Watson Wyatt on the consulting
side, and Lee Overlay, Record Treasury, and Pareto Partners from
the managers side found consensus during a round table discussion
of currency issues for UK pension funds.
All
seven agreed that:
• Currency risk is an important issue for trustees
• Trustees need to have a defined currency risk management policy
• Active management of currency risk has a high probability of adding
value
•
Currency risk is best managed independently, either by in-house
overlay specialists or specialist external overlay managers.
Bailey sees consultants as important potential drives of currency
hedging. “They are becoming more aware of currency overlay. In the
US, some have got involved in promoting it, which has been a very
useful development.” UK consultants are aware of their role in building
a trend. “Part of the blame for the slow take-up lies with ourselves
in not raising it with our clients forcefully and proactively enough,
although we are making an effort to remedy that now,” Mercer’s Muysken
admits.
However,
the bigger barrier, it seems, is more insidious. “Part of it is
just inertia. It takes a long time to change old habits,” he adds.
Frank Russell’s Collie says there are all sorts of barriers to implementing
a currency overlay programme – he cites possible distortion of the
overall strategy, cash flow implications, the need to ensure multiple
managers’ decisions are aligned, and the simple reality of having
another manager to deal with – but he says these are probably surmountable
challenges. The greater blockages are inertia and fashion, he agrees.
“What funds ought to do, based on sound investment strategy and
what funds actually do, varies wildly,” says Collie. “There is a
large element of fashion and flavour-of-the-month in the decisions
they make. Even if our conclusion is that currency overlay is good
and that they should do it, there is no guarantee that all funds
will.”
