Long-Term Supply and Demand
To understand the long-term demand and supply in commodity markets, let us take a look at a few of the indicators that are used.
Production and Reserves
The supply of crude oil can be gauged by the production of crude oil (measured in millions of barrels per day), the amount of reserves of crude oil, specifically proved reserves (Figure 1.5), and the ratio of reserves to production (Figure 1.6), which gives an estimate of the number of years that the reserves can be expected to last. As expected, when the production of crude oil is high, prices are generally lower, although in general supply growth has tended to lag demand growth, leading to a gradually rising average price over the last two decades.

Long-term prices are affected by the amount of reserves remaining. Proved reserves of oil (also called “1P”) are those reserves that can be recovered in the future from known reservoirs with reasonable certainty (usually 90 % confidence) under present-day economic and operating conditions. Probable reserves correspond to a 50 % confidence level of recovery (called “2P” or proved plus probable), and possible reserves are those that have a less likely chance of being recovered (at least a 10 % chance) and are called “3P” (proved + probable + possible). Disclosures regarding reserves can be affected by local accounting rules and whether the company reporting the figures is private or public. Since a number of national oil companies are private, the reserve numbers reported by them do not have the same level of scrutiny.
Reserve growth predictions are also affected by developments in technology. For instance, prior to the large-scale commercialization of hydraulic fracturing (“fracking”) technology to exploit shale oil reserves and other technological innovations of the last decade, it was widely believed that oil would turn expensive. This was because oil production in the USA had peaked in the early 1970s (known as Hubbert's peak after M. King Hubbert, a US geologist) and the world's production was expected to peak in 1995. However, the introduction of new technologies and the increased viability of developing more difficult-to-extract reserves, such as oil sands, with higher prices of crude oil have combined to allow oil production to continue to grow.
In addition, in recent years there has been a discussion on reviewing the reserves of companies to account for “unburnable reserves” arising from the fact that it would be impossible to utilize some of the reserves if global warming targets are to be met. Similarly, carbon capture and storage (CCS) technologies would need to be developed before all the disclosed hydrocarbon reserves could be tapped. However, it is not yet clear if there is an appreciable impact of this concern on oil prices or the stock prices of energy companies.
Refining and Consumption
Refining capacity is an indicator of the maximum supply of oil products. Demand can be gauged from the consumption of crude oil and the consumption of individual refined products. Refinery throughput or capacity utilization is another measure of the demand for refined products. Data on imports and exports, as in Figure 1.7, can also provide clues about the geographical distribution of demand and supply as well as the energy security of individual countries or regions.

Trends in Economic Activity
The pace of economic activity is a good barometer of commodity consumption. An acceleration in GDP growth rate leads to higher usage of crude oil and other commodities, leading to higher prices during the uptrend in the economic cycle. Conversely, a contraction in economic output can lead to a sharp fall in commodity prices, as evidenced in the fall of 2008–09, when oil prices dropped from their highs of over 140$/bbl to lows of below 40$/bbl.
Technological Advances
Technological advances affect expectations of long-term supply and demand. For example, rising oil prices make it viable to develop more producing assets, thus increasing future reserves and production. However, rising oil prices also spur investment in alternative energy sources and shape future demand as well. For example, the development of hydroelectric, solar, wind, and other forms of energy generation, the growth in the usage of biofuels and compressed natural gas (CNG) for transportation, as well as heightened public awareness and demand for electric-powered vehicles and hybrids are all consequences of higher oil prices. The environmental impact of using oil can also be credited with the development of tougher standards on emissions, reducing energy intensity of new technologies, and increasing investments in alternative energy.
Short-Term Supply and Demand: Supply Chain and Infrastructure
Short-term supply and demand are affected by disruptions in the supply chain of the commodity. For example, the hurricanes Katrina and Rita led to a drop of over 1 million bbl/day in crude oil output from the Gulf of Mexico and refined product capacity was significantly reduced (by a third of national capacity at one point). Maintenance of oil rigs and other equipment can also lead to short-term price dislocations.
Upstream
Upstream production capacity and spare capacity affect prices as well. The amount of spare capacity maintained by OPEC, especially Saudi Arabia, has an effect on containing price rises. OPEC is an international organization, which aims to coordinate the petroleum policies of member countries and ensure the stabilization of oil markets. Its members, as of mid-2015, are the states of Algeria, Angola, Ecuador, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, the United Arab Emirates, and Venezuela. OPEC accounts for over 81 % of the world's crude oil reserves as of 2012, and produces about a third of global production, thereby wielding significant influence over oil prices.
Refining
Prices of crude oil are also affected by their usability in refineries and refining capacity. As refineries are large installations, which are constructed over a long period of time, refining capacity is finite and inelastic and refineries are typically configured to handle a specific type of crude oil. Thus, price trends for crude oil will be affected by the refining capacity available to process that particular blend of oil. For example, if it is more profitable to refine heavy crude oil in a complex refinery (vs. light crude oil), complex refineries will run at full capacity, reducing
