St. Louis Fed's Bullard Discusses Zero Interest Rate Policy
3/18/2016
FRANKFURT, Germany – Federal Reserve Bank of St. Louis President James Bullard
discussed “Permazero in Europe?” at the International Research Forum on Monetary
Policy on Friday.
Bullard noted that the purpose of the Frankfurt conference is to promote the discussion
of innovative research on issues relevant for monetary policy. “In this spirit, I will

discuss some recent ‘neo-Fisherian’ ideas and what they might mean for the G-7 over
the medium term,” he said. In particular, he examined the possibility of remaining at
zero or near-zero policy rates over the medium term and the implications for monetary
policy.
The Macroeconomic Equilibrium of 1984-2007
In the U.S., Bullard said that the key argument for monetary policy normalization is that
while the goals of the Federal Open Market Committee (FOMC) have essentially been
met, policy settings remain extreme. Regarding the FOMC’s goals, he noted that U.S.
labor markets are close to normal and that in ation net of the oil price shock is
reasonably close to the FOMC’s target rate of 2 percent. In contrast, the policy rate
(currently at a target range of 0.25-0.50 percent) remains about 3 percentage points
below the FOMC’s long-run level, and the Fed’s balance sheet remains more than $3.5
trillion larger than its pre-crisis level.

“Prudent policy suggests edging the policy rate and the balance sheet toward more
normal levels,” Bullard said.

Speeches & Presentations

He noted that implicit in the argument for normalization in the U.S. is a desire to return
to the macroeconomic equilibrium of 1984-2007. This period was characterized by
relatively long economic expansions, relatively shallow recessions and relatively good
monetary policy that was well understood by policymakers and nancial markets.

“That equilibrium was associated with a higher nominal interest rate structure than we
have today,” Bullard said, adding, “however, what if we cannot return to such a
situation?”
He proceeded to examine the implications of this question, particularly given that the
U.S. has been near the zero lower bound on the policy rate for the past several years
and that the average short-term nominal interest rate among the G-7 countries is
expected to be close to zero over the medium term. Furthermore, even if countries raise
their policy rates from near zero, Bullard noted that negative shocks to the economy are

always possible and have the potential to push short-term nominal interest rates back
to the zero lower bound.
Permazero and Neo-Fisherian Ideas
“Zero interest rate policy (ZIRP) has usually been viewed as temporary and as part of a
policy reaction to a very large macroeconomic shock. But ZIRP or near-ZIRP has been
in place for seven years, far beyond the duration consistent with ordinary business
cycle uctuations,” Bullard said, adding, “arguably, this is an interest rate peg—a
constant value of the policy rate independent of changes in macroeconomic
conditions.”
He pointed out that many economists believe an interest rate peg is poor monetary
policy, since trying to keep the short-term nominal interest rate unnaturally low could
lead to instability in the form of very high in ation. However, he noted that overall
in ation remains below target even after having ZIRP or near-ZIRP for seven years.
“Perhaps in ation is still in the pipeline? Or, perhaps, is it time for a new model?”
To this end, he then explored the implications of neo-Fisherian ideas that include the
core idea that an interest rate peg, in some circumstances, can be stable. In this
context, “ZIRP, far from being a harbinger of runaway in ation, would instead dictate
medium- and long-term in ation outcomes,” he said. (For additional discussion, see
Bullard’s speech on Nov. 12, 2015, “Permazero.”)
Bullard said that the policy implications of these neo-Fisherian ideas are profound. “The
continuing ZIRP in the G-7, far from putting dangerous upward pressure on in ation,
may be leading us to an outcome with low nominal interest rates and low in ation that
can last for a very long time,” he said. “This contrasts sharply with conventional wisdom
and central bank rhetoric, including much of my own, which emphasizes that ZIRP is
putting upward pressure on in ation and offers the best hope for returning in ation to
target.”
Empirical Evidence
To see how neo-Fisherian ideas match up with actual experience in the G-7 countries,
Bullard examined the paths of the average short-term nominal interest rate and in ation
rate in the G-7 countries since 2002. He noted that the average policy rate went to near
zero following the Lehman-AIG event in September 2008, and is unlikely to deviate
signi cantly from ZIRP over the medium term. Regarding G-7 in ation, although it
returned to the 2 percent target after the nancial crisis, it has declined about 3
percentage points since 2012.
“Developments in the G-7 since 2012 could be interpreted as neo-Fisherian effects
taking hold,” Bullard said. In addition, he discussed how euro area data also point to a
compelling neo-Fisherian story. “If ZIRP was su cient to drive in ation back to target
by 2012, why has continued ZIRP not kept in ation close to target or pushed it even
higher?”
In conclusion, given the focus of the conference on issues that may be important for
the medium- and long-term monetary policy outlook, Bullard said, “Neo-Fisherian ideas
may have an important impact on our thinking about monetary policy in the future.”
