Price of oilThe price of oil, or the oil price, generally refers to the spot price of a barrel () of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil, Isthmus, and Western Canadian Select (WCS). Oil prices are determined by global supply and demand, rather than any country's domestic production level. The global price of crude oil was relatively consistent in the nineteenth century and early twentieth century.
1979 oil crisisA drop in oil production in the wake of the Iranian Revolution led to an energy crisis in 1979. Although the global oil supply only decreased by approximately four percent, the oil markets' reaction raised the price of crude oil drastically over the next 12 months, more than doubling it to . The sudden increase in price was connected with fuel shortages and long lines at gas stations similar to the 1973 oil crisis. In 1980, following the onset of the Iran–Iraq War, oil production in Iran fell drastically.
2000s commodities boomThe 2000s commodities boom or the commodities super cycle was the rise of many physical commodity prices (such as those of food, oil, metals, chemicals and fuels) during the early 21st century (2000–2014), following the Great Commodities Depression of the 1980s and 1990s. The boom was largely due to the rising demand from emerging markets such as the BRIC countries, particularly China during the period from 1992 to 2013, as well as the result of concerns over long-term supply availability.
Energy crisisAn energy crisis or energy shortage is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular, those that supply national electricity grids or those used as fuel in industrial development. Population growth has led to a surge in the global demand for energy in recent years.
2007–2008 world food price crisisThe world food price crisis refers to a period of time when the cost of food increased significantly and had a profound impact on the availability and affordability of food for people around the world. This crisis is often characterized by sharp spikes in the prices of key staple foods such as wheat, rice, and corn, as well as other agricultural commodities such as sugar and oil. The causes of the world food price crisis are complex and multifaceted, but they generally involve a combination of factors including droughts and other weather-related events, increased demand for biofuels, trade policies, and financial speculation.
2010s oil glutThe 2010s oil glut was a significant surplus of crude oil that started in 2014–2015 and accelerated in 2016, with multiple causes. They include general oversupply as unconventional US and Canadian tight oil (shale oil) production reached critical volumes, geopolitical rivalries among oil-producing nations, falling demand across commodities markets due to the deceleration of the Chinese economy, and possible restraint of long-term demand as environmental policy promotes fuel efficiency and steers an increasing share of energy consumption away from fossil fuels.
Food pricesFood prices refer to the average price level for food across countries, regions and on a global scale. Food prices affect producers and consumers of food. Price levels depend on the food production process, including food marketing and food distribution. Fluctuation in food prices is determined by a number of compounding factors. Geopolitical events, global demand, exchange rates, government policy, diseases and crop yield, energy costs, availability of natural resources for agriculture, food speculation, changes in the use of soil and weather events directly affect food prices.
Peak oilPeak oil is the point in time when the maximum rate of global oil production is reached, after which production will begin an irreversible decline. It is related to the distinct concept of oil depletion; while global petroleum reserves are finite, the limiting factor is not whether the oil exists but whether it can be extracted economically at a given price. A secular decline in oil extraction could be caused both by depletion of accessible reserves and by reductions in demand that reduce the price relative to the cost of extraction, as might be induced to reduce carbon emissions.
Great RecessionThe Great Recession was a period of marked general decline observed in national economies globally, i.e. a recession, that occurred from late 2007 to 2009. The scale and timing of the recession varied from country to country (see map). At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression. One result was a serious disruption of normal international relations.
1970s energy crisisThe 1970s energy crisis occurred when the Western world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages as well as elevated prices. The two worst crises of this period were the 1973 oil crisis and the 1979 energy crisis, when, respectively, the Yom Kippur War and the Iranian Revolution triggered interruptions in Middle Eastern oil exports. The crisis began to unfold as petroleum production in the United States and some other parts of the world peaked in the late 1960s and early 1970s.
