How Did Short-Term Market Rates React to Liftoff?
By Renee Haltom and Alexander L. Wolman

The implementation of monetary policy has changed significantly since 2008.
In particular, very large excess reserves in the financial system have led to the
creation of new tools to manage the federal funds rate. Given these changes,
some observers have wondered how money market interest rates would
respond to “liftoff,” the Fed’s first interest rate increase from effectively zero.
Since liftoff in December 2015, it appears that the Fed’s influence over
short-term interest rates remains intact.
On December 16, 2015, the Federal Open Market
Committee (FOMC) raised the target federal funds
rate for the first time in nearly 10 years after keeping it at effectively zero for seven years.
A notable facet of this event was that the Fed
raised rates despite having a very large balance
sheet with substantial excess reserves in the financial system, a result of actions taken in response
to the 2008 financial crisis and the Great Recession. Some observers have since questioned how
markets would react to liftoff in such a scenario –
that is, whether the Fed exerts the same degree
of “control” over short-term market interest rates
as it did when reserves were more scarce.
This Economic Brief will explore how liftoff would
have been expected to affect markets in the old
world, why some have wondered whether the
Fed’s influence over market rates would have
changed in the new world, and how markets did,
in fact, respond to liftoff.
The Fed’s Influence over Market Interest Rates
In general terms, the Fed conducts monetary
policy by attempting to make the market-based

rates influenced by its policy settings track the
economy’s underlying “natural” rate of interest.1
Operationally, the Fed does this by directly influencing selected short-term rates within the
financial system, which in turn influences rates
paid by a wide variety of public and private parties in the broader market.
The Fed influences market rates at all ends of
the maturity spectrum. Longer-term rates are
what drive much economic activity – especially
investment decisions and the financing of major
consumer purchases such as houses and automobiles. The Fed’s influence over long-term
rates is limited in the short run, however. Longterm rates are a function of both the path of
short-term rates and a “term premium,” the nature and determinants of which are subjects of
much debate.2
An episode that well demonstrated the Fed’s
limited control over long-term rates occurred
after the Fed raised the target federal funds rate
(the rate banks pay to borrow money from one
another overnight) in 2004, from historically low
levels, for the first time in four years. During a

series of rate hikes into the following year, the tenyear Treasury yield failed to rise much. In February
2005, after dismissing several common hypotheses
to explain the behavior, then-Chairman Alan Greenspan famously referred to the failed correlation as
a “conundrum.”
More recently, certain monetary policy initiatives –
quantitative easing, Operation Twist, and forward
guidance – took steps specifically to influence longterm rates. The first two, in particular, attempted to
do so through very large purchases of longer-term
assets. Researchers have debated how much of an
effect these programs had on longer-term interest
rates, as well as to what extent the effect they did
have was due to the purchases themselves versus
the signaling effect about the likely path of future
short-term interest rates.3 Nonetheless, as a usual
course of policy implementation, longer-term rates
wouldn’t necessarily be expected to move in lockstep with the Fed’s policy rates.
Stronger Influence over Short-Term Rates
A better gauge of the degree of the Fed’s influence
over market rates is provided by looking at shorterterm rates. There has been some discussion about
whether the Fed’s degree of influence over market
rates would be different in the new world of large
excess reserves.
For example, some observers have argued that the
Fed’s large balance sheet – which ballooned from
less than $1 trillion in late 2008 to roughly $4.5 trillion today – should make it inherently difficult for
the Fed to control short-term rates. This notion may
stem from how monetary policy has historically
been conducted. In the past, the Fed set a target for
the fed funds rate and achieved that rate by influencing the supply of reserves in the banking system
in line with estimates of the demand for reserves.
(Moreover, because the Fed had built up credibility
for achieving its target rate, trading often would
occur at a rate near or equal to the target fed funds
rate with only small open market operations by the
Fed.) Under this system, reserves were relatively
scarce, and there was a low level of excess reserves
in the banking system.

Monetary policy implementation has changed, however. The Fed’s response to the financial crisis and
Great Recession entailed large asset purchases and
thus a large expansion of the Fed’s balance sheet and
reserves in the banking system. The Fed received authority in October 2008 to pay banks interest on their
reserve balances, which provided a tool – known as
IOR, or interest on reserves – for inducing banks to
maintain high levels of excess reserves. Otherwise
the expansion of the Fed’s balance sheet – and the
corresponding increase in the supply of reserves –
would hinder the Fed’s ability to achieve its fed funds
target. In other words, IOR provides a tool for the Fed
to influence short-term market rates even with a very
large balance sheet and a large quantity of excess
reserves. In principle, IOR ought to do so by setting a
floor on the fed funds rate.
Other observers have wondered what effect liftoff
would have on short-term market rates because IOR
initially failed to create the floor on the fed funds
rate that it was intended to provide. One major reason is that some institutions – including the government-sponsored enterprises and some international
institutions – hold reserves with the Fed but are not
eligible to receive IOR. As such, these institutions
would not be content to hold large excess reserves.
They also tend to be net sellers in the fed funds
market and may have been willing to lend in the fed
funds market below the IOR rate, putting downward
pressure on the fed funds rate. Banks, in turn, would
be able to earn risk-free profit by borrowing at the
fed funds rate and holding the borrowed funds as
reserves, earning IOR. A 2011 paper by Morten L.
Bech of the New York Fed and Elizabeth Klee of the
Fed’s Board of Governors explores such an environment of large excess reserves in which some parties
are eligible for IOR and some are not.4 Their model
shows how this could contribute to the effective fed
funds rate falling below the IOR rate, even though
raising IOR still could exert upward pressure on
market rates.
When the Fed eventually decided to raise rates,
there was good reason to believe that raising IOR
alone would pull up short-term market rates, with
a modest spread between IOR and the fed funds

rate persisting. However, as an insurance policy,
the Fed created an alternative investment opportunity, an overnight reverse repurchase, or repo,
agreement facility (known as ON RRP) for money
markets. In principle, ON RRP would complement
IOR and influence money markets without requiring reserve draining. A reverse repo is a transaction
in which a security is sold with the simultaneous
agreement to reverse the sale at a specified price
and set future date. In ON RRP, the interest rate
paid by the Fed on the reverse repo is determined
by the difference between the two sales’ prices
and the duration of the contract. As described by
Simon Potter, head of the New York Fed’s open
market desk, in an early 2016 speech, instead of
altering reserve levels directly, this facility focused
on influencing market rates by intensifying competition in money markets.5 As Potter stated, “Instead
of running quantity-based, term operations aimed
at altering reserve levels, the Desk would run
interest-rate-based overnight operations aimed
directly at influencing market rates.”

Even with the combination of IOR and the ON RRP
facility, it was possible that liftoff would not work
exactly as planned – that is, that the fed funds rate
and other money market rates might not rise in
lockstep with IOR. As a result, Potter noted, while
the pre-liftoff testing suggested that the tools were
likely to work well, it wasn’t possible to determine
with certainty the extent to which market rates were
driven by the tools versus features of the financial
system near the zero lower bound on nominal interest rates that may have helped keep the target fed
funds rate within range.
How Markets Responded to Liftoff
The FOMC raised its target fed funds rate at its
December 16, 2015, meeting. Money market rates
moved much as one would expect: they rose essentially in lockstep with liftoff. (See Figure 1.)
One can see short-term rates rising in the weeks
before liftoff, reflecting the market’s increasing
expectation that liftoff would indeed happen at the

December 2015 meeting. The means of short-term
rates rose proportionally after liftoff: by 28 basis
points for one-month financial commercial paper,
25 basis points for one-month nonfinancial commercial paper, 26 basis points for LIBOR, 28 basis
points for overnight repos, and 20 basis points for
one-month treasuries.6 (There are reasons to expect
that Treasury bills will not rise to the same degree
as other rates in a way that does not suggest the
Fed has less influence over money market rates.7)
The standard deviations increased only slightly.

Fed can change the average level of market rates, but
there is high and unpredictable volatility on spreads
between the IOR rate and other short-term rates,
then it is possible that the Fed would have a communication problem and that its credibility would suffer.
The market could interpret unintended deviations of
the effective rate from the target rate as a change in
the stance of policy. In the recent past, for example,
the media has suspected the Fed of “stealth” monetary policy when the effective rate differed from the
target rate.8

After liftoff, longer-term Treasury rates fell. (See
Figure 2.) This can be explained partly by an increased demand for long-term treasuries that may
have resulted from, among other factors, soft global growth and regulatory changes that increased
interest from banks and money market mutual
funds. As noted above, the reaction of long-term
interest rates does not necessarily suggest the Fed’s
influence over markets is lacking or different in the
new world given the volatile term premium that is
a major determinant of longer-term interest rates.

However, despite some concern that the Fed’s fundamental relationship with markets has changed in a
world with large excess reserves and IOR, key shortterm rates have thus far responded tightly to liftoff,
with comparable increases in mean interest rates and
no major change in standard deviations.

The market’s response to liftoff matters because if
the Fed cannot change short-term market interest
rates, then monetary policy is essentially powerless.
The market’s response also matters because if the
