St. Louis Fed's Bullard Discusses "A Cautionary Note
on U.S. Monetary Policy Normalization"
May 28, 2018
TOKYO – Federal Reserve Bank of St. Louis President James Bullard discussed “A
Cautionary Note on U.S. Monetary Policy Normalization” on Tuesday at the Japan Center for
International Finance’s Global Finance Seminar.
In the talk, Bullard explained that U.S. monetary policy has been normalizing during the
last 2½ years, with the Fed’s balance sheet shrinking relative to U.S. GDP and the Fed’s
policy rate (i.e., the federal funds rate target) increasing relative to policy rates in key
foreign economies.
He posed the question: “How far can the Fed go along the current normalization path, given
the likely paths of other key economies?” He then presented three reasons for caution in
deciding whether to raise the U.S. policy rate further in the near term. The reasons spanned
the following areas: in�ation expectations, the neutral policy rate and the �attening yield
curve.

U.S. market-based in�ation expectations remain somewhat
low
“In�ation expectations in the U.S. remain somewhat low, suggesting that further
normalization may not be necessary to keep in�ation near target,” Bullard said.
He noted that, on a PCE basis, U.S. market-based in�ation expectations remain centered
below the Federal Open Market Committee’s (FOMC or Committee) 2 percent in�ation
target, inhibiting the FOMC’s ability to maintain the credibility of the target.1
Bullard explained that these market-based in�ation expectations can be interpreted as
saying that �nancial markets don’t believe the Fed will quite hit its in�ation target, even
over the next �ve years. He added that this market judgment already prices in all current
macroeconomic developments, including a market expectation of future Fed policy, which
tends to be somewhat more dovish than the FOMC’s policy rate outlook.

“These developments suggest that �nancial markets believe in�ationary pressure in the
U.S. is likely to be muted over the forecast horizon,” he said.
Bullard pointed out that market-based in�ation expectations may have increased recently,
in part, because of developments in global crude oil markets, a factor that should ultimately
have only temporary effects on in�ation.
“A reasonable policy going forward may be to temper the pace of normalization in order to
re-center in�ation expectations at the Committee’s 2 percent target,” he said.

The current U.S. policy rate is neutral
Bullard noted that the policy rate setting is likely at the longer-run neutral level today,
putting neither upward nor downward pressure on in�ation. “This suggests that it may not
be necessary to change the policy rate to keep in�ation at target,” he said.
In recalling analysis he did earlier this year, he said the level of the trend short-term safe
real interest rate, the so-called “r-star,” is a starting point for the appropriate nominal policy
rate. His analysis suggests that r-star remains in negative territory.
“That analysis also suggests that the nominal policy rate set by the FOMC is already
pressing against the upper bound of a neutral setting,” he said.

The U.S. yield curve is relatively �at
Bullard noted that the U.S. nominal yield curve has �attened since 2014. The spread
between the 10-year and one-year Treasury yields went from close to 300 basis points at
the beginning of 2014 to only 76 basis points as of the week of May 16. He attributed the
�attening to rising short-term yields vis-à-vis relatively stable or slowly rising long-term
yields.
He noted that it is possible that the yield curve will invert sometime in the next year. If
inversion does occur, he said, research by the Federal Reserve Bank of San Francisco
suggests that the signal of an impending economic downturn would be strong. “In my view,
it is unnecessary for the FOMC to be so aggressive as to invert the yield curve,” he said.
He also pointed out that the international evidence on the relationship between yield curve
inversions and subsequent recessions is not as strong as it is for the U.S. alone.
“The U.S. nominal yield curve could invert later this year or in 2019, which would be a
bearish signal for U.S. macroeconomic prospects,” he said.
1 The FOMC’s in�ation target is in terms of the annual change in the price index for

personal consumption expenditures (PCE). Bullard explained that market-based measures
of in�ation expectations, which are for CPI in�ation, need to be adjusted downward
somewhat to roughly translate into PCE in�ation.
