St. Louis Fed's Bullard Discusses Three Challenges to Central Bank
Orthodoxy
10/13/2015
WASHINGTON, D.C. – Federal Reserve Bank of St. Louis President James Bullard on
Tuesday discussed “More on Three Challenges to Central Bank Orthodoxy” at the 57th
annual meeting of the National Association for Business Economics (NABE).
During his presentation, Bullard said that U.S. monetary policy is at a crossroads
because central bank orthodoxy is being challenged. He outlined his version of a
“classic” or “orthodox” interpretation of current macroeconomic events along with three
challenges to that interpretation, which relate to strict in ation targeting, low real

interest rates and globalization.
The orthodox view emphasizes the cumulative success that has been achieved so far
with respect to the Federal Open Market Committee’s (FOMC’s) goals for in ation and
unemployment. “The Committee has arguably achieved its objectives as well today as it
has at any time since 1960,” Bullard said. Despite that, Bullard noted, the FOMC’s policy
settings remain at emergency levels.
“The orthodoxy suggests a prudent policy of returning policy settings to more normal
levels gradually over time, providing plenty of monetary accommodation during the
transition to guard against macroeconomic risks,” he said.
Bullard noted that all three challenges to the orthodoxy claim that some aspect of it is
de cient in the current environment, and that “this time is different.” While the
challenges are interesting, Bullard said they fall short of providing a reliable guide for
U.S. monetary policy.
Strict In ation Targeting
The rst challenge, which he called “strict in ation targeting,” suggests that labor
markets have been overemphasized. In particular, it suggests: 1) the Phillips curve
relationships have broken down completely or are badly damaged, or 2) all the
information needed from the Phillips curve can be read off of actual in ation
outcomes. “Either way, this challenge puts much less weight on labor market outcomes
relative to the orthodox view,” Bullard said. According to this view, he noted, in ation is
the only variable the FOMC needs to consider when setting monetary policy.
“An important drawback to the strict in ation targeting view is that it cannot easily
justify the current policy of a zero interest rate,” Bullard argued, noting that the current
in ation gap is too small to rationalize a zero policy rate based on low in ation alone.

“Strict in ation targeting may provide a reason to set the policy rate below its long-run
level, but not all the way to zero,” Bullard said.
Low Real Interest Rates
The next challenge relates to the notion that real interest rates on short-term
government debt and related securities are exceptionally low globally. Thus, the second
challenge to central bank orthodoxy is to emphasize the implications of very low and
time-varying real rates. He explained that this challenge suggests that monetary policy
is actually not very accommodative today, and therefore, the zero interest rate policy
(ZIRP) may remain appropriate.
“This challenge to orthodoxy, like others, is interesting,” Bullard said, “but it is unlikely
that the current ZIRP can be rationalized by an appeal to low real interest rates alone,”
he added. “By some measures, the traditional assumption of a constant short-term real
rate equal to 2 percent is about right in today’s environment,” he said.
Globalization
The third challenge that Bullard discussed suggests that because of increasing
globalization, foreign economic developments need to be taken into account,
separately and distinctly, in U.S. monetary policy deliberations.
However, Bullard noted literature on global monetary policy that suggests that if each
policymaker pursues an appropriate domestically oriented monetary policy, the global
allocation of resources will be optimal, or close to optimal. This implies that the
domestic policymaker does not need to react separately and distinctly to foreign output
or foreign in ation gaps. Furthermore, Bullard noted that this result does not depend on
the degree of globalization.
Normalization
Bullard said these three challenges to central bank orthodoxy ultimately do not provide
su ciently robust arguments to guide current U.S. monetary policy, and that the
orthodoxy remains the best basis for near- and medium-term monetary policy decisionmaking.
“The orthodoxy argues for normalization of U.S. monetary policy based on cumulative
progress toward Committee goals,” Bullard noted. He emphasized that policy will
remain exceptionally accommodative even as normalization proceeds, given that policy
settings are far from anything that could be called restrictive. “This continued
accommodation will provide plenty of insurance against any remaining risks to the U.S.
economy, and simultaneously it will mitigate against the dangers of maintaining
extreme policy settings in an environment where conventional gaps have essentially
narrowed to zero,” Bullard said.
