Sweet crude oilSweet crude oil is a type of petroleum. The New York Mercantile Exchange designates petroleum with less than 0.5% sulfur as sweet. Petroleum containing higher levels of sulfur is called sour crude oil. Sweet crude oil contains small amounts of hydrogen sulfide and carbon dioxide. High-quality, low-sulfur crude oil is commonly used for processing into gasoline and is in high demand, particularly in industrialized nations.
1990 oil price shockThe 1990 oil price shock occurred in response to the Iraqi invasion of Kuwait on August 2, 1990, Saddam Hussein's second invasion of a fellow OPEC member. Lasting only nine months, the price spike was less extreme and of shorter duration than the previous oil crises of 1973–1974 and 1979–1980, but the spike still contributed to the recession of the early 1990s in the United States. The average monthly price of oil rose from 17perbarrelinJulyto36 per barrel in October. As the U.S. 2000s energy crisisFrom the mid-1980s to September 2003, the inflation-adjusted price of a barrel of crude oil on NYMEX was generally under US25/barrelin2008dollars.During2003,thepriceroseabove30, reached 60by11August2005,andpeakedat147.30 in July 2008. Commentators attributed these price increases to many factors, including Middle East tension, soaring demand from China, the falling value of the U.S. dollar, reports showing a decline in petroleum reserves, worries over peak oil, and financial speculation. Petrodollar recyclingPetrodollar recycling is the international spending or investment of a country's revenues from petroleum exports ("petrodollars"). It generally refers to the phenomenon of major petroleum-exporting states, mainly the OPEC members plus Russia and Norway, earning more money from the export of crude oil than they could efficiently invest in their own economies. The resulting global interdependencies and financial flows, from oil producers back to oil consumers, can reach a scale of hundreds of billions of US dollars per year – including a wide range of transactions in a variety of currencies, some pegged to the US dollar and some not.
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.
North Sea oilNorth Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea. In the petroleum industry, the term "North Sea" often includes areas such as the Norwegian Sea and the area known as "West of Shetland", "the Atlantic Frontier" or "the Atlantic Margin" that is not geographically part of the North Sea. Brent crude is still used today as a standard benchmark for pricing oil, although the contract now refers to a blend of oils from fields in the northern North Sea.
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.
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.
2021–2023 global energy crisisThe 2021–2023 global energy crisis began in the aftermath of the COVID-19 pandemic in 2021, with much of the globe facing shortages and increased prices in oil, gas and electricity markets. The crisis was caused by a variety of economic factors, including the rapid post-pandemic economic rebound that outpaced energy supply, and escalated into a widespread global energy crisis following the Russian invasion of Ukraine. The price of natural gas reached record highs, and as a result, so did electricity in some markets.
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.
