Introduction and summary
The United States is in a period of low interest rates
following the Great Recession, which lasted from late
2007 through mid-2009. And the Federal Reserve re-
cently reaf
fi
rmed expectations for a lengthy period of
low rates, likely to last at least through mid-2015.
1
Low interest rates are expected to reduce the cost of
investing in the United States. In turn, increased levels
of investment are expected to decrease unemployment
over time—an objective that is consistent with the
maximum employment component of the Federal
Reserve’s dual mandate.

While a prolonged period of low interest rates is
intended to achieve a broad macroeconomic policy
objective, individual sectors of the economy may be
more or less sensitive to changes in interest rates. Thus,
the impact of the policy on these sectors will vary
accordingly. In this article, we focus on the impact of
the interest rate environment on the life insurance in-
dustry, which is an important part of the U.S. economy
and its
fi
nancial system. Life insurance companies held
$5.6 trillion in
fi
nancial assets at year-end 2012, com-
pared with $15.0 trillion in assets held by banks at year-
end 2012.

In addition to life insurers being large in
absolute terms, these companies have special signi
fi
-
cance in that they hold large amounts of speci
fi
c types
of assets. For instance, life insurers held 6.2 percent of
total outstanding credit market instruments, including
17.8 percent of all outstanding corporate and foreign
bonds, in the United States (see
fi
gure 1).

Life insurers are exposed to the interest rate environ-
ment because they sell long-term products whose pres-
ent
value depends on interest rates. On a fundamental
level, the products satisfy two objectives for customers.
The
fi
rst objective is that insurance customers want pro-
tection from adverse
fi
nancial consequences resulting
from either loss of life (by buying life insurance poli-
cies) or exhaustion of
fi
nancial resources over time
(by buying annuity policies). The second objective is
to allow customers to save (generally in a tax-advan-
taged way) for the future. Because customers are ex-
pected to receive cash from their policies years after
they have been issued, life insurers face the challenge
of investing the customers’ payments in such a way that
the funds are available to satisfy policyholders in the
distant future. This feature generally leads life insurers
to invest in a collection of long-term assets, mostly
bonds. Life insurers generally invest largely in
fi
xed-
income securities because most of their liabilities are

the end of 2012, 38.9 percent of life insurance

As interest rates change, the values of a life insurer’s
assets and liabilities change, potentially exposing the
company to risk. Life insurers choose assets to back
their liabilities with interest rate risk in mind but may
not choose to—or may not be able to—completely
balance the interest rate sensitivity of their assets and
liabilities. This con
fl
ict arises in part because assets with
maturities as long as those of some insurance liabilities
are not always available. Moreover, there is an addi-
tional complication. Many life insurance and annuity
products have embedded guarantees or attached riders
that promise policyholders a minimum return over the
duration of their policies. As interest rates decrease,
these guarantees or riders can affect how sensitive these
products are to interest rate changes.
Life insurers are also exposed to interest rate risk
through the behavior of policyholders. The interest
rate environment affects demand by policyholders for
certain insurance products. For example,
fi
xed-rate
annuities can promise a prespeci
fi
ed return for invest-
ments over a potentially extended period. When interest
rates are very low, as they are currently, life insurers
can only make money on these annuities if they offer
policyholders a low return. There is less demand for
annuities under these conditions. Also, many insurance
products offer policyholders the option to contribute addi-
tional funds at their discretion or to close out a contract
in return for a predetermined payment (in the latter case,
the policyholder is said
to surrender the
contract; see
the next section for details). When interest rates change,
it is more likely that policyholders
will act on these op-
tions. For example, they may contribute more to an
annuity with a high guaranteed return when interest
rates are low or surrender an annuity with a low return
guarantee if interest rates rise signi
fi
cantly.
There is a widespread belief—both among inves-
tors and life insurance
fi
rms—that the current period of
low interest rates is bad for life insurance
fi
rms. The
stock prices of life insurers fell in a strong stock market.
From the end of December 2010 through the end of
December 2012, the Standard & Poor’s (S&P) 500 Life
& Health Index, which tracks the stock performance
of life and health insurance
fi
rms in the United States,
decreased 9.1 percent, whereas the S&P 500 Index, which
tracks the stock performance of the top 500 publicly
traded
fi
rms of the U.S. economy, increased 18.5 percent;
all the while, interest rates fell signi
fi
cantly.
