Gasoline and Oil Prices
Summary
American gasoline consumers faced rapidly escalating prices during the first
half of 2008, followed by declining prices in the second half. As prices increased to
over $4.00 per gallon, consumers faced difficult choices concerning how to allocate
limited budgets as the economy slowed. The price increases also adversely affected
major industries, including automobile production, transportation, and agriculture.
The high gasoline prices also were thought to contribute to the slow-down in
economic growth and the potential for general price inflation. The oil industry
earned record corporate profits while other sectors of the economy were negatively
affected.
Gasoline prices did not increase on their own over this period. The rising price
of gasoline was driven by the increasing price of crude oil, the major cost component
of gasoline. Crude oil prices, which peaked at just under $150 per barrel in July, and
then turned down, rose more quickly than gasoline prices, and the cost share of crude
oil per gallon of gasoline rose, putting cost pressure on the refining, distribution, and
marketing sectors of the gasoline supply chain.
While the recent increases in the price of crude oil began in late 2007, the price
of oil has been increasing, at different rates, since 2004. Many factors have
contributed to the price increases over this period. Over the past five years, the mix
of factors affecting price at any particular time has varied.
Recently, several factors, including the continuing increase in world oil demand,
the effect of speculation on energy futures markets, the transformation of the energy
futures market into a pure financial market rather than a commodity market, the
declining value of the dollar, foreign governments’ fuel subsidization, and limits to
the ability of the market to increase supply, have been identified as key in explaining
oil, and therefore gasoline price volatility. The key factor of world oil demand is
rapidly weakening as world growth in gross domestic product slows in the fourth
quarter of 2008 and forecasted growth estimates for 2009 are reduced.
Policy debates have focused on curbing speculation on oil futures markets by
increasing regulatory presence. Over three dozen pieces of legislation have beenth
introduced in the 110 Congress to address speculation-related issues. Other possible
policy directions have included declaring a moratorium on collection of the federal
excise tax on gasoline, conservation, and the use of oil in the Strategic Petroleum
Reserve to augment U.S. supplies of crude oil. Additionally, the possibility of
drilling in currently excluded areas on the Atlantic and Pacific outer continental shelf,
as well as the Gulf of Mexico, have been considered. The potential opening of the
Alaska National Wildlife Refuge for oil exploration and development has also been
debated.
The oil market has demonstrated a tendency to be cyclic and sharply volatile.
Policy measures that assume long-term stability in the market are unlikely to attain
the multiplicity of goals for oil policy the American public desires.

Gasoline and Oil Prices
During the summer of 2008, American consumers faced gasoline prices that
attained record high levels of over $4.00 per gallon, and oil prices of more than $1401
per barrel. These high prices contributed to a downturn in economic growth and an
increase in inflation. They forced consumers to make difficult choices concerning
spending patterns, while their general economic well-being declined. The record
prices raised costs and adversely affected a wide variety of industries, including
transportation, automobiles, and agriculture.
As of the week of October 20, 2008, gasoline prices were at $2.91 per gallon
and the price of oil was below $70 per barrel.2 However, this favorable news for U.S.
consumers came in an environment of financial and credit market problems, and
growing fears that the nation was facing an economic recession.
Because there does not seem to be one, easily identifiable, factor that has caused
the quick surge in oil prices, consensus on how to mitigate the situation through
policy has been elusive. Calls for increased exploration and drilling in Alaska and
currently restricted offshore areas, energy conservation, increased reliance on
alternative energy sources, curbing speculation on oil futures markets, releasing oil
from the Strategic Petroleum Reserve, suspending the federal tax on gasoline, and
taxing the profits of oil companies have all been debated.
While it may be easier to identify the first-order causes of the rapid decline in
oil prices, declining oil product demand linked to a world-wide slowdown in
economic growth, other factors that contributed to the price increases earlier in 2008
could also be identified.
This report examines the extent of price volatility in gasoline and oil markets,
focuses on the linkage between the two, and analyzes the causes of the price
increases and the likelihood that they have been reversed through market responses
or policy measures.
Gasoline and Oil Price Volatility
The Energy Information Administration (EIA) reported that retail gasoline
prices increased by 33% from January through July 2008, or, by over $1 per gallon.3
Although the price was higher in each month in 2008, on a month-by-month basis,


1 Diesel and aviation fuel prices increased at least as much as gasoline prices.

compared to 2007, the greatest differential was observed in July, when prices were
about $1.10 per gallon higher than in the previous year.
These price increases led consumers to respond by using less gasoline and
driving fewer miles. By mid-July 2008, gasoline demand had declined by about
340,000 barrels per day (b/d), or 3.6%, compared to a similar period in 2007.4 By
October 2008, gasoline demand compared to the same period in 2007 was down by
about 392,000 b/d, or 4.2%.5 Miles traveled declined by 3.7% in May 2008 compared
to May 2007, and 3.6% in July 2008 compared to July 2007.6 These responses are
important because they represent a potential market adjustment that could result in
the moderating of the price increases of the first half of 2008. If consumption did not
decline in the face of sharp price increases, there would be little incentive for
producers not to continue raising prices.

As gasoline prices fall during the fourth quarter of 2008, they could provide
consumers an incentive to increase consumption. However, slower economic growth,
job losses, and reduced incomes are likely to depress gasoline consumption. As a
result the price effect, which acts to stimulate gasoline consumption, is likely to be
offset by an income effect, which acts to reduce gasoline consumption.

During the price increases of the first half of 2008, the cost composition of
gasoline changed. Table 2 shows that not only did crude oil cost more per gallon of
gasoline, but its share of the total price increased. Crude oil cost about $1.54 per
gallon of gasoline in June 2007, rose to $3.00 per gallon of gasoline in June 2008,
and fell to $2.16 per gallon by October 2008.

Refining, as a share of the cost of a gallon of gasoline declined by over 50%,
and fell from $0.69 per gallon in 2007, to $0.36 per gallon in 2008. This nearly 48%
fall in cash flow to refiners has reversed the economic performance of refiners in
recent years, and puts into even greater question the possibility of expanding the U.S.
refining capacity base. Distribution and marketing’s share of the price of a gallon of
gasoline also declined from June 2007 to October 2008, putting pressure on gas
station owners as they saw their net return per gallon sold fall. Taxes were less
affected by the growing role of crude oil in the cost structure of gasoline because,
while the federal excise tax on gasoline is a fixed $0.184 per gallon, and as a result
will decline in percentage terms as the price of gasoline rises, some state and local
taxes on gasoline are percent of value, or ad valorem, taxes and will retain a constant
share of cost as the price of gasoline rises.
The data presented in Table 2 suggest that the major reason the price of gasoline
has been volatile in 2008 is because the price of crude oil has been volatile. The rise
and fall in the price of crude oil has not only affected consumers, it has affected
virtually all the parts of the gasoline supply chain.

Table 1 and Table 3 show that while the price of crude oil rose by about 24%
in the second half of 2007, the price of gasoline rose by only about 2% over the same
time period. While crude oil prices increased by another 44% in the first half of
2008, gasoline prices increased by 34% over the same period. Anticipated and actual
cuts in demand for gasoline may have caused firms to resist passing the full cost
increases of crude oil on to consumers in 2007, increasing the rate at which gasoline
prices rose in early 2008.
Crude oil prices fell by 22% from July through September 2008, while gasoline
prices fell by only about 9%. Partial data for October 2008 suggest that the average
price of crude oil fell to about $86 per barrel, or 17% compared to September 2008,
while the price of gasoline fell by about 14% during the same period. The lags in
passing declining costs on to consumers may be due to inventory policies that require
the covering of past costs, or to attempts by the refining industry to enhance returns
after a period of reduced earnings in 2008.
Factors Affecting Oil Prices
The price of oil is set on a world market, over which no firm has direct control.
However, the market differs in significant ways from the economic conception of a
free, competitive, market. Five countries-the United States, China, Japan, India, and
South Korea-consumed over 45% of the world demand of 85.2 million barrels per
day in 2007, while producing only 14% of world production. As a result, these
countries, as well as many other net consuming nations, depend on world trade in
crude oil. Since production of crude oil depends on a geological formation to yield
the oil, only certain places in the world can produce oil at high levels, in excess of



their own consumption. These areas are concentrated in the Persian Gulf, where over
60% of known proved reserves are located. Reserves can be augmented, and
production can be increased, only after the expenditure of billions of dollars and
years of development after a discovery. The Persian Gulf oil producers and others
attempt to exercise control of the price of oil through the Organization of the
Petroleum Exporting Countries (OPEC).
Because of the characteristics of consumers and producers in the market, both
the demand and the supply sides of the market are very inelastic, or price insensitive,
in the short and intermediate term. Since neither consumers nor producers can easily
make quantity adjustments in response to changing prices, the market price may not
be singular. There may be a range of prices that are consistent with the market
avoiding physical shortages or surpluses. In this type of market environment, high
levels of price volatility are likely.
World Demand
A frequently cited reason for high crude oil prices is the growth of world
demand, driven by China and India.

200277,8291.2
Source: BP Statistical Review of World Energy 2008.
Note: Growth is the percentage change in a year over the previous year.
Table 4 shows that the total growth in demand over the past five years of 7.5%
is higher than the total growth of 5.3% over the previous five years. Over the past
five years, from 2003 to 2007, consumption growth in China totaled 35%, higher
than the world growth rate. However, the growth of Chinese demand cannot be
considered in isolation. Since the crude oil market is world-wide, the high level of
Chinese growth should be considered only in the context of total world demand
growth.7
Although 1997 and 2004 stand out as years in which annual growth exceeded
the ten year average of 1.3%, the data in Table 4 might not appear to suggest that


7 For example, total consumption demand in Japan and Europe declined between 2006 and

2007. This reduced demand translated into more available supply to satisfy Chinese demand.



demand growth could be sufficient to push crude oil prices to the record levels
observed in July 2008. In the case of the oil market, it may be that percentage
changes taken alone are misleading.
Because of the nature of oil production, which is characterized by time lags, an
inability to easily expand output from existing fields, and low incentives to keep
production as excess capacity, the actual volume of demand increases, irrespective
of the percentage value, is a key factor. This differentiates the oil industry from other
manufacturing and service industries where marginal percentage increments in output
can be met by using the existing capital stock and labor force more intensively.
The demand increase of 3.5%, or over 2.8 million b/d, in 2004, reduced spare
capacity in the world, and created a tight balance between demand and supply. When
growth fell to 1.5% in 2005, that, nonetheless, represented a further expansion of
required world production by 1.2 million b/d. Because world production could not
expand quickly enough to meet this new demand, further reductions in excess
capacity occurred and the tight market conditions continued. When an increase in
demand causes total demand to exceed current production, it must be met by
reducing excess capacity. When excess capacity in the industry falls, markets
anticipate that the reduced excess capacity is less able to accommodate future
possible supply disruptions and, as a result, the price increases.
The solution to rising prices, if one concludes that world demand growth cannot
be controlled in the long run, is expansion of output. However, the largest oil
reserves are believed to be already discovered and in production. Future fields might
well be smaller and more costly. Data shows that in 2007, the world level of proven
reserves declined from 1.239 trillion barrels to 1.237 trillion barrels, suggesting that
new discoveries did not offset 2007 production levels.8
Estimates of world oil demand for 2009 are being revised downward. The
International Energy Agency (IEA) cut its forecast world demand for crude oil by
500,000 b/d for the second half of 2008. In addition, it cut 400,000 b/d from its
forecast for 2009. These revisions yield a 2009 world oil demand of 87.2 million b/d,
some 700,000 b/d over 2008 levels.9 Although the IEA sees demand declining in the
industrialized nations, it sees demand continuing to increase in emerging markets.
The reason for the reduction in forecast world oil demand is a declining outlook
for world economic growth. The International Monetary Fund (IMF) forecast for
world gross domestic product growth for 2008 was 3.9%, and for 2009 is 3.0%, after
5.0% growth in 2007. The financial crisis being experienced on world markets and
the continuing effects of high commodity prices are blamed for reduced growth.10

Financial Speculation
One of the most debated factors in rising oil prices has been the role of
speculators, particularly those investing through commodity index funds.
Speculators have always been part of energy futures markets, but it generally has
been as the other side of hedging transactions by physical traders.11 Their role has
been to accept price risk when physical traders sought to transfer it, and lock-in
prices. Recently, however, commodities’ futures markets have become part of
financial investor portfolio strategies. As a result, the market has seen an inflow of
new participants that have no interest in the physical commodity, beyond the
possibility of profiting from its price variations.
The oil futures market is actually composed of three different markets; regulated
futures exchanges like the New York Mercantile Exchange (NYMEX), electronic
trading facilities like the Intercontinental Exchange (ICE), and the Over the Counter
(OTC), or swap market. Each market offers a different contract, traded under
different rules, and with different degrees of regulatory control.12 The focus for oil
price effects has recently been on the NYMEX where a standardized futures contract,
based on West Texas Intermediate (WTI) crude oil, deliverable at Cushing,
Oklahoma, is traded under the regulation of the Commodities Futures Trading
Commission (CFTC). This market is financial in nature, in the sense that little or no
oil actually is traded, or changes hands. Almost all contract gains and losses are
settled in cash, and positions, either long (as a holder of the right to buy oil) or short
(as a holder of the right to sell oil) can be closed out, or offset by purchasing a
contract that offsets the original position.
In principle, there is little reason why any transaction on the oil futures markets
should affect the current price of oil. What is being traded in these markets is a
contract that obligates an investor to buy oil one month, or more, in the future at a
known, set, price. If more investors desire to be in that position, the demand for the
contract goes up, taking with it the contract price at which that oil might be traded.
Again, in principle, this transaction does not affect any demand or supply
fundamental in the physical oil market, and should not necessarily affect the current
price of oil. In general, it is more likely that shifts in the underlying fundamentals of
oil demand and supply could affect the expectations of future prices held by
investors, and alter their behavior causing them to buy or sell, leading to price
variations that reflect the evolving market forces in the physical market.
In the real market for oil, it is possible that purely financially based
expectations, realized through changing positions in the financial markets, might
affect the real price of oil. The spot market, a market for the delivery of real crude
oil, bases its price on the futures market, and EIA data show that the two prices vary
only by a few cents as observed in Table 5.


11 See CRS Report RL31923, Derivatives, Risk Management, and Policy in the Energy
Markets, by Robert Pirog, for more on the mechanics of the hedging process.
12 See CRS Report RL34555, Speculation and Energy Prices: Legislative Responses, by
Mark Jickling and Lynn J. Cunningham, for more on the focus and degree of oversight and
regulation.

The reason for this close correlation is that the spot price is in itself a forward
price. Oil contracted today on the spot market must generally be delivered within
twenty-one days, with notice given to the buyer prior to delivery. The near month
futures contract generally covers thirty days or less into the future, hence there is
substantial overlap between futures market contract delivery and spot market
delivery. As a result, the NYMEX near month futures price is the basis for the spot
market price, adjusted for relatively minor differences in delivery time and other
factors. This linkage between the spot and futures market price is the connection
between the financial oil market and the real oil market. It allows investment
decisions by financial institutions and investment funds to be transferred quickly and
directly to gasoline consumers.

It is possible to take almost the reverse position on the spot versus future price
correlation. In this view, the futures price must always adjust to the spot price. At
the expiration date of the futures contract, the spot price must equal the futures price
on the expiring contract because the holder of futures contracts can always choose
to receive oil rather than a cash settlement if desired. Futures prices are seen as
driven by expectations of the future spot price. In this market conception, the
primary control mechanism is that essentially all of the futures market participants
are real commodity hedgers.13


13 David L. Crawford, “Oil Futures” Are a Phony Target, Philadelphia Daily News, August

4, 2008.



Several factors are important in balancing these arguments. The approach that
claims futures markets control the spot price are based on investor behavior that is
at odds with that of the perfectly rational financial investor of economic theory. For
this approach to have validity, two tests should be met. First, there should be a class
of participants in the market that are not hedgers in the sense of having a need to lock
in the price of oil for commercial use, for example, purely financial investors.
Second, there should be some explanation, and evidence, that the non-commercial
class of market participants were likely making investment decisions driven by some
other rationale beyond that of rational economic, financial analysis.
No definite, quantitative evidence is available for either condition; however,
testimony given at congressional hearings indicates that new participants may be
entering the oil futures markets in the form of investment by commodity index
funds. 14

The data in Table 6 show that over a five year period, holdings of crude oil and
gasoline in the form of futures contracts, by investors in commodity index funds
increased by over 500% in the case of WTI crude oil, and over 200% in the case of
gasoline. Investors in these funds include pension funds, university endowments,
private investors, hedge funds and sovereign wealth funds. Commodity index funds
pool investors’ funds and purchase futures contracts in a wide variety of commodities
markets, including agriculture, livestock, energy, base, and precious metals. In each
of these markets, the funds have expanded their holdings since 2003 in amounts
comparable to those observed in Table 6.15
The purpose of commodity index fund investment is not to gain title to
commodities; the funds settle their contract positions in cash. The goal is the benefit
of diversification as well as the potential for high rates of return. Commodity prices
are thought to vary inversely with financial investments in traditional corporate
shares and bonds. For example, if the Dow Jones Industrial Average of corporate
shares declines on a particular day, investors might expect to observe an increase in
the index value of commodity futures. This inverse performance of financial and
commodity markets reduces the over-all risk in investors’ portfolios, and presents
investors a more favorable risk/return profile.

Governmental Affairs, United States Senate, May 20, 2008.

Since futures contracts in energy markets have a finite time horizon, when the
contracts expire, new contracts must be purchased to keep the target balance between
stocks, bonds, and commodities in place. As a result, once commodity index fund
managers determine that commodity investments are a desirable part of their
portfolios, this new source of demand is, in effect, permanent. Any new source of
demand, driven not by the fundamentals, or expectations, of oil demand and supply,
but by portfolio decisions is likely to raise the price of an oil contract on the futures
market, which is transmitted directly to consumers through the linkage between the
futures and spot market prices.
For commodity index investments to be an important factor in the increasing
price of oil over time, not only must there be an initial expansion of demand, but
growing demand in each subsequent time period. This type of demand growth might
result from favorable expectations concerning the fundamentals of the oil market, or
it could result from a herd mentality among portfolio managers, which could
contribute to a financial bubble due to speculators entering the commodity futures
market and driving up prices of contracts. If the commodity futures market has a bias
toward this type of upward price movement, and it is supported by strong
fundamentals in the real commodity markets, growing demand and/or tight supplies,
it is likely that the result will be increasing prices, as observed in the price of oil since

2004.


If the effects of financial speculation either increased the price of oil or caused
the price to rise faster than justified by market fundamentals during the first half of
2008, they are likely to have similar, but reverse, effects during the current market
downturn. The financial crisis has provided incentives for financial firms and hedge
funds to move to a more liquid investment position, increasing their cash balances.
This allows the firms to strengthen their balance sheets by reducing their holdings of
risky assets, and provides readily accessible reserves should investors demand to
withdraw their funds.
Although data is not available, it is likely that some speculative, financial
positions on commodity markets have been liquidated as firms strive to increase their
cash holdings. This attempt to sell oil could possibly cause the price of oil on the
NYMEX to fall, or fall more quickly than justified by the weakening fundamentals
in the world oil market.
Value of the Dollar
Many analysts believe the price of oil varies inversely with the value of the
dollar against other major currencies, notably the euro. Oil is priced in dollars on the
international market. If the dollar falls in value against another currency, it takes
fewer units of that currency to purchase the requisite number of dollars needed to buy
a barrel of oil. As a result, oil becomes cheaper in the other currency, say the euro,
than in dollars. The price of oil measured in dollars then rises. Each dollar purchases
a smaller fraction of a barrel of oil as a result. Holding oil, rather than dollars,
becomes a way to protect against a declining dollar.
Over the period of rising oil prices, 2004 to mid-2008, the euro/dollar exchange
rate has been variable. From January 2, 2004 to January 3, 2005, the euro increased
in value relative to the dollar, by 7%. From January 3, 2005 to January 3, 2006, the



euro declined in value relative to the dollar by 11%. From January 3, 2006, to
January 2, 2007 the euro increased in value relative to the dollar by 10.8%. From
January 2, 2007 to January 2, 2008 the euro increased in value relative to the dollar
by 10.9%.16
The increasing value of the euro in 2007 may have been a factor in the
increasing price of oil over the same period. As of the end of October 2008, the
dollar had begun to strengthen, or increase in value, with respect to the euro and the
British pound sterling. This increase in the value of the dollar would tend to weaken
the price of oil if the same relationship observed in 2007 continues to hold.
National Subsidies
In many areas of the world, gasoline consumers have been protected from the
effects of higher world oil prices by their governments through fuel subsidies. For
example, it was reported that in July 2008 the price for a gallon of gasoline in
Venezuela was $0.12, $0.40 in Iran, $0.45 in Saudi Arabia, and $0.89 in Egypt.17
High population countries like China, Indonesia, and Russia also subsidize gasoline.
The effect of fuel subsidies is to reduce the ability of the natural market forces
of demand to lower price. Consumers make decisions based on artificially set prices.
Consumption is higher than it would be if they faced the market price. Producers see
less reason to lower prices because demand continues to be strong. The demand
effect also affects consumers in nations that do not subsidize. Although consumers
in the non-subsidy countries may cut back on consumption when faced with higher
prices, their decisions may be negated by demand growth in subsidized markets. In
this way, governments that subsidize fuel costs in their domestic markets are
adopting a strategy which supports oil producers and high prices.
Nations that subsidize fuel costs do pay a price, whether they are oil exporters
or not. The subsidy is generally a large drain on the national treasury, causes
inefficient allocation of resources, and anomalies in trade. For example, Iran exports
over 2 million barrels per day of crude oil, but imports gasoline because of domestic
demand for gasoline that exceeds Iran’s refining capacity.
Oil Supply
Oil supply is relatively insensitive to price changes in the short run. More oil
production can enter the market in times of high prices only if excess capacity exists18
at producing fields, given the level of demand. Similarly, production only
minimally declines when prices fall, because it is uneconomic to cut production rates
at producing fields, due to the wide spread between the cost of extraction and typical
levels of price observed over the past five years, as well as high fixed costs. Excess
capacity is thought to exist only in the Organization of the Petroleum Exporting
Countries (OPEC).

18 Excess capacity is sometimes referred to as “spare capacity.”

Excess capacity hit a recent peak of about 7 million barrels per day in 2002, and
has been lower than peak, but increasing, since 2004. Table 7 shows the pivotal role
played by Saudi Arabia in the world oil market. Saudi excess capacity accounted for
82% of OPEC spare capacity in 2005, and 61% in 2007. Nigerian oil production is
subject to disruption due to political upheaval, and Iran and the oil importing nations
are at odds over Iran’s nuclear ambitions. The most direct way to augment spare
capacity in the short-run is through demand reduction, generally as a result of higher
prices and slowing economic growth. Because excess capacity has increased over the
2007-2008 period, it is unlikely that excess capacity constraints were the major factor
in the recent price increases.
In the longer term, if world demand for oil continues to grow as more nations
develop and gain income and wealth, excess capacity is likely to be tight, unless high
levels of investment in productive capacity take place. Investment in productive
capacity is limited by “resource nationalism.” Resource nationalism refers to the
practices of countries with known, or suspected, oil reserves that limit access to those
potential supplies. If national oil companies, either due to lack of funding, or
expertise, or political direction, fail to develop oil resources the world oil market is
likely to have difficulty keeping up with world demand, perpetuating high prices.

Oil importing countries can create excess capacity in the world market by
reducing their own demand, or augmenting their own oil production, if they hold oil
reserves. While it is unlikely that any importing countries hold undeveloped reserves
comparable to those in the larger OPEC nations, even more modest increases in
production may reduce prices due to the price insensitive nature of oil demand. In
this type of market, with a low degree of price sensitivity, relatively small changes
in production might affect both current and future prices.
Policy Issues
The increases in gasoline and oil prices have led to a number of congressional
initiatives. Based on the number of bills introduced, a primary focus of the 110th
Congress has been on curbing oil speculation activities. Proposed legislation has
focused on: closing a variety of regulatory loopholes that have prevented regulatory
authorities from exercising oversight, increasing regulatory resources, assigning
emergency regulatory powers, and attempting to reduce the desirability of energy
futures trading by increasing margin requirements, as well as data reporting.19 Over
three dozen pieces of proposed legislation were considered in the 110th Congress. It
is possible, that because activities on the oil futures markets may have escaped
regulatory scrutiny, strategies were undertaken that resulted in price manipulation.
Other policy approaches suggested to reduce gasoline prices included the
suspension of the federal excise tax on gasoline. This tax is $0.184 cents per gallon,
and the revenue generated is applied to the Highway Trust Fund. Concern was
expressed as to whether the tax suspension would be passed on to consumers by
refiners who collected the tax, and whether highway construction projects and the
local employment they support would be adversely affected.20
In September of 2008, the Highway Trust Fund was approaching a zero balance,
a condition that would threaten the continuation and completion of construction
projects all over the country. The shortfall in funds came about as a result of reduced
revenues linked to declining gasoline purchases resulting from higher prices. A
transfer of $8 billion from the U.S. Treasury to the Highway Trust Fund (P.L. 110-

318) was authorized on September 15, 2008.


The United States maintains a Strategic Petroleum Reserve of almost 750
million barrels of oil. Some have suggested that releasing oil from the reserve might
reduce prices at the pump. Others felt that the amounts of oil that could be feasibly
released were insufficient to affect gasoline prices, or that the OPEC nations might
cut their output in response, cancelling any price effect.
Debate also has taken place concerning expansion of domestic supply, by
drilling the restricted areas of the outer continental shelf, and other areas. This
centered on areas currently excluded from oil development on the Atlantic and

Pacific coasts, as well as some excluded areas in the Gulf of Mexico.21 Also
discussed was opening restricted areas in the Alaska National Wildlife Reserve to
exploration and development. It is believed that producible oil deposits exist in these
areas, but environmental concerns, the time lag required to complete development,
as well as whether the deposits would be significant enough to affect prices in the
current and future market, were critical factors in the debate.
Conclusion
Since the 1970s, the oil market has been both cyclic and volatile. Periods of
high prices have been followed by price collapses. Up and down turns in price have
been abrupt as well as drawn out. Policy proposals that assume that market behavior
is predictable and can be projected into the future, are likely to be of limited
effectiveness.
Additionally, there have been many goals set out for oil policy, some of them
contradictory. For example, over the first half of 2008 there has been interest in
lowering gasoline prices, reducing oil dependence, and reducing carbon emissions
associated with global warming. Success in lowering gasoline prices would likely
increase consumption, which likely would lead to increased oil imports, given the
inability of the United States to increase production in the very short term. Increased
consumption of petroleum products increases carbon emissions which could make
the attainment of any desired emission target more difficult to obtain.
Market forces, both fundamental and financial, changed the direction of both the
prices of oil and gasoline. In the 16-week period July 7, 2008, to October 20, 2008,
national average gasoline prices fell from $4.165 to $2.914 per gallon, a decline of
more than 30%. NYMEX oil futures prices were $145.29 per barrel for WTI on July
3, 2008. On October 21, 2008, WTI was trading at about $71 per barrel, a decline
of about 51%. These declines in prices were as unanticipated as the price increases
from January through July. The oil market can be volatile and change direction
quickly. That these observed price decreases come as Russia invaded Georgia,
threatening oil pipeline shipments from Azerbaijan, unrest and violence continue to
occur in Nigeria, and other de-stabilizing factors affect the market, makes their
timing unanticipated.
Should these declines in price persist, and reverse most, or all, of the price
increases that took place in the first half of 2008, the immediate pressure to control
oil and gasoline prices through government policy might be reduced. Nevertheless,
the market conditions that drove oil to record levels could quickly re-appear, if for
example, U.S. economic growth picked up.
Policy making in a volatile market is difficult. It may also be hard for the
industry to carry out a satisfactory investment plan that is consistent with policy
objectives. The capital intensity and high costs of major oil projects require target
prices to be attained to provide economic justification. In a sharply volatile market,

the industry might not respond in the desired way to a policy measure. For example,
policy measures that have the goals of increasing exploration and development of
new oil fields, or expanding the capacity the oil refining sector as a way to mitigate
high consumer prices, might not be undertaken by the industry if corporate planners
view high prices as transitory, and lower prices are incorporated in the company’s
investment planning.
