Introduction

Recent developments in global oil prices
Crude oil prices have fallen dramatically since mid-2014.
Oil price movements are an important component of headline
inflation in the U.S.
 Year-over-year headline inflation in the U.S. is currently very
low.

Fed officials have sometimes argued that once oil prices
stabilize, headline inflation will naturally return to 2 percent.
However, crude oil prices have not stabilized in recent weeks,
and instead have fallen substantially further.
What are the implications for current monetary policy?

This talk
First, I will consider the very recent movements in oil prices
in historical context.
Second, I will review the argument that stabilization of oil
prices implies that headline inflation will return to target.
 This argument still holds, but it now appears that this process
will take longer than previously thought.

Third, I will consider the possibility that inflation
expectations are falling in the U.S.
Fourth, I will discuss the degree to which lower oil prices are
ultimately a bullish factor for the U.S. economy.

Preview of conclusions
The recent movements in crude oil prices are very substantial
in historical context.
Headline inflation will return to target once oil prices
stabilize, but recent further declines in global oil prices are
calling into question when such a stabilization may occur.
Inflation expectations in the U.S. may be falling. If so, this
would put downward pressure on inflation.
Relatively low oil prices remain a net positive for the U.S.
economy.

Recent Crude Oil Price Declines

Recent nominal crude oil price declines
The price of crude oil began to decline in the summer of
2014.
It fell by more than half by the beginning of 2015, from
above $105 per barrel to below $50 per barrel.
Since early November 2015, the price has fallen an additional
40 percent by some measures.
Most of the large movements came in the second half of
2014.

Recent crude oil price declines in real terms
The real dollar price of crude oil was arguably stable between
1988 and 2003 at approximately $30 per barrel in 2009
dollars.
A key event, as yet unidentified in the academic literature,
occurred in 2003 and the real dollar price of oil nearly tripled
by 2008 to approximately $85 per barrel in 2009 dollars.
This higher level was maintained for 6 ½ years, until mid2014, despite the global financial crisis and its aftermath.
Recent declines have been substantial, but not quite enough
to return the real dollar price to its 1988-2003 average value
in 2009 dollars.

Supply responses
Nearly tripling the price of any good or service will attract
attention.
Many previously unused forms of oil extraction became
economically feasible during the 2008-2014 price regime.
This supply response has likely led to overcapacity in global
oil markets and caused the current downdraft of prices.
However, financial markets often interpret oil price declines
as declines in the global demand for goods and services.
 Sometimes arguments in this camp cite declines in commodity
prices generally.

Crude Oil Prices and Headline Inflation

Crude oil prices and headline inflation
The Fed’s 2 percent inflation goal is stated in terms of
headline personal consumption expenditures (PCE) inflation.
Large movements in crude oil prices can influence this
measure of inflation substantially.
This is why year-over-year headline inflation is quite low
today.
 One way to control for this is to consider the Dallas Fed’s
trimmed-mean PCE inflation rate, which is currently about 1.7
percent year-over-year.

Headline inflation once oil prices stabilize
The fall in crude oil prices to lower levels, even if maintained
indefinitely, has only a one-time influence on the year-overyear inflation rate.
Let’s suppose that oil prices had stabilized around the
November 2015 level (approximately $40/barrel) and
remained at that level for several years.*
Let’s further suppose that all other prices had continued to
increase at the same pace as they did during 2015.
What would the headline consumer price index (CPI)
inflation rate be at the end of 2016 under such a scenario?
 Answer: More than 2 percent.
* Oil prices, measured by the U.S. crude oil imported acquisition cost by refiners,
were at $38.70 per barrel in November 2015.

Has this argument changed?
The renewed fall in crude oil prices since November 2015
calls into question this line of thinking.
How would this calculation change given the new downward
pressure on crude oil prices?

Headline inflation once oil prices stabilize
To assess the new situation, let’s now suppose hypothetically
that oil prices continue to fall and only stabilize around
$20/barrel by June 2016 and remain at that level for several
years.
Let’s further suppose that all other prices continue to increase
at the same pace as they did during 2015.
What would the headline CPI inflation rate be at the end of
2016 under such a scenario?
 Answer: 0.6 percent, not reaching 2 percent until mid-2017.

Bottom line: The argument is the same, but it takes longer
for CPI inflation to return above 2 percent.

Crude Oil Price Declines and Inflation
Expectations

Crude oil prices and inflation expectations
Traditional central banking argues that policymakers should
“look through” changes in crude oil and other commodity
prices in order to gauge underlying trend inflation.
 This is the purpose of a measure like the Dallas Fed’s trimmed
mean PCE inflation rate.

However, one circumstance where one may be more
concerned is when inflation expectations themselves begin to
change due to the changes in crude oil prices.
Arguably, such a phenomenon is occurring in the current
environment.

Market-based measures of inflation expectations
Market-based indicators of inflation expectations, such as the
Treasury Inflation Protected Securities (TIPS) spreads, have
fallen in tandem with the fall in crude oil prices since the
middle of 2014.
Longer-term inflation expectations, such as the five-yearfive-year-forward breakeven inflation rate, should in
principle be independent of movements in crude oil prices.
Nevertheless, the correlation between the two variables has
been very high over the last 18 months.

Expected inflation and actual inflation
Expectations of inflation are a major determinant of actual
inflation according to modern macroeconomic theory.
Low inflation expectations may keep actual inflation lower,
all else equal, making it more difficult for the Fed to return
inflation to target.
I have argued that market-based measures of inflation
expectations have been unduly influenced by the large
movements in crude oil prices.
Nevertheless, with renewed declines in crude oil prices in
recent weeks, the associated decline in market-based inflation
expectations measures is becoming worrisome.

Crude Oil Prices and the U.S. Economy

Crude oil prices and the U.S. economy
Crude oil price declines since mid-2014 are helping to keep
headline inflation very low in the U.S.
For the macroeconomy as a whole, the relatively low crude
oil prices the U.S. is enjoying today are likely a bullish
factor.
Automobile sales, for instance, have been strong.
More generally, real personal consumption expenditures
(PCE) growth accelerated during the period of the large drop
in oil prices from mid-2014 to mid-2015.
This could be viewed as mild evidence that the oil price
decline is a bullish factor for the U.S.

Summary

Summary
The recent movements in crude oil prices are very substantial
in historical context.
Headline inflation will return to target once oil prices
stabilize, but recent further declines in global oil prices are
calling into question when such a stabilization may occur.
Inflation expectations in the U.S. may be falling. If so, this
would put downward pressure on inflation.
Relatively low oil prices remain a net positive for the U.S.
economy.
