World oil market chronology from 2003
- This article is a chronology of events affecting the oil market. For a discussion of the energy crisis of the same period, see 2000s energy crisis and Effects of 2000s energy crisis. For current fuel prices see Gasoline usage and pricing.
From the mid-1980s to September 2003, the inflation adjusted price of a barrel of crude oil on NYMEX was generally under $25/barrel. Then, during 2004, the price rose above $40, and then $50. A series of events led the price to exceed $60 by August 11, 2005, leading to a record-speed hike that reached $75 by the middle of 2006. Prices then dropped back to $60/barrel by the early part of 2007 before rising steeply again to $92/barrel by October 2007, and $99.29/barrel for December futures in New York on November 21, 2007. Throughout the first half of 2008, oil regularly reached record high prices. Prices on June 27, 2008, touched $141.71/barrel, for August delivery in the New York Mercantile Exchange (after the recent $140.56/barrel), amid Libya's threat to cut output, and OPEC's president predicted prices may reach $170 by the Northern summer. The most recent price per barrel maximum of $147.02 was reached on July 11, 2008. After falling below $100 in the late summer of 2008, prices rose again in late September. On September 22, oil rose over $25 to $130 before settling again to $120.92, marking a record one-day gain of $16.37. Electronic crude oil trading was temporarily halted by NYMEX when the daily price rise limit of $10 was reached, but the limit was reset seconds later and trading resumed. By October 16, prices had fallen again to below $70, and on November 6 oil closed below $60. Then in 2009, prices went slightly higher, although not to the extent of the 2005-2007 crisis, exceeding $100 in 2011 and most of 2012. Since late 2013 the oil price has fallen below the $100 mark, plummeting below the $50 mark one year later.
As the price of producing petroleum did not rise significantly, the price increases have coincided with a period of record profits for the oil industry. Between 2004 and 2007, the profits of the six supermajors - ExxonMobil, Total, Shell, BP, Chevron, and ConocoPhillips - totaled $494.8 billion.
||The examples and perspective in this article deal primarily with the United States and do not represent a worldwide view of the subject. (December 2010)|
United States crude oil prices averaged $30 a barrel in 2003 due to political instability within various oil producing nations. It rose 19% from the average in 2002. The 2003 invasion of Iraq marked a significant event for oil markets because Iraq contains a large amount of global oil reserves. The conflict coincided with an increase in global demand for petroleum, but it also reduced Iraq's current oil production and has been blamed for increasing oil prices. However, oil company CEO Matthew Simmons emphasizes the peaking and decline of oil-exporting in Mexico, Indonesia and the United Kingdom is the reason for the price gouging. According to Simmons, isolated events, such as the Iraq war, affect short-term prices but do not determine a long-term trend. Simmons cites the use of enhanced oil recovery techniques in large fields such as Mexico's Cantarell, which maintained production for a few years until it eventually declined. Pumping oil out of Iraq may reduce petroleum prices in the short term, but will be unable to perpetually lower the price. From Simmons' point of view, the invasion of Iraq is associated with the start of long-term increase in oil prices, but it may mitigate the decline in oil production by retaining a partial amount of Iraq's oil reserves. As a direct consequence, the oil production capacity was diminished to 2 million barrels (320,000 m3) per day.
2004 to 2008: rising costs of oil
After retreating for several months in late 2004 and early 2005, crude oil prices rose to new highs in March 2005. The price on NYMEX has been above $50 per barrel since March 5, 2005. In June 2005, crude oil prices broke the psychological barrier of $60 per barrel.
From 2005 onwards, the price elasticity of the crude oil market changed significantly. Before 2005 a small increase in oil price lead to an noticeable expansion of the production volume. Later price rises let the production grow only by small numbers. This was the reason to call 2005 a tipping point.
After the destruction of Hurricane Katrina in the United States, gasoline prices reached a record high during the first week of September 2005. The average retail price was, on average, $3.04 per U.S. gallon. The average retail price of a liter of petrol in the United Kingdom was 86.4p on October 19, 2006, or $6.13 per gallon. Oil production in Iraq continued to decline as result of the nation's ongoing conflict causing a decrease in production to 1 million barrels per day (160,000 m3/d).
In mid-2006, crude oil was traded for over USD 79 per barrel (bbl), setting an all-time record. The run-up is attributed to a 1.9 increase in gasoline consumption, geopolitical tensions resulting from North Korea's missile launch. The ongoing Iraq war, as well as Israel and Lebanon going to war are also causative factors. The higher price of oil substantially cut growth of world oil demand in 2006, including a reduction in oil demand of the OECD. After news of North Korea's successful nuclear test on October 9, 2006, oil prices rose past $60 a barrel, but fell back the next day.
On October 19, 2007, U.S. light crude rose to $90.02 per barrel due to a combination of ongoing tensions in eastern Turkey and the reducing strength of the U.S. dollar. Prices fell briefly on the expectation of increased U.S. crude oil stocks, however they quickly rose to a peak of $92.22 on October 26, 2007.
On January 2, 2008, U.S. light crude surpassed $100 per barrel before falling to $99.69 due to tensions on New Years Day in Nigeria, and on suspicion that U.S. crude stocks will have dropped for the seventh consecutive week. A BBC report from the following day stated a single trader bid up the price; Stephen Schork, a former floor trader on the New York Mercantile Exchange and the editor of an oil market newsletter, said one floor trader bought 1,000 barrels (160 m3), the smallest amount permitted, and immediately sold it for $99.40 at a $600 loss. Oil fell back later in the week to $97.91 at the close of trading on Friday, January 4, in part due to a weak jobs report that showed unemployment had risen.
On March 5, 2008, OPEC accused the United States of economic "mismanagement" that was pushing oil prices to record highs, rebuffing calls to boost output and laying blame at the George W. Bush administration. Oil prices surged above $110 to a new inflation-adjusted record on March 12, 2008 before settling at $109.92. On April 18, 2008 the price of oil broke $117 per barrel after a Nigerian militant group claimed an attack on an oil pipeline. Oil prices rose to a new high of $119.90 a barrel on April 22, 2008, before dipping and then rising $3 on April 25, 2008 to $119.10 on the New York Mercantile Exchange after a news report that a ship contracted by the U.S. Military Sealift Command fired at an Iranian boat.
On June 6, prices rose $11 in 24 hours, the largest gain in history due to the possibility of an Israeli attack on Iran. The combination of two major oil suppliers reducing supply generated fears of a repeat of the 1973 oil crisis. The mid-July decision of Saudi Arabia to increase oil output caused little significant influence on prices. According to the oil minister of the Islamic Republic of Iran, Gholam-Hossein Nozari, the world markets were saturated and a Saudi promise of increased production would not lower prices. Several Asian refineries were refusing Saudi petroleum in late June because they were over priced grade.
On July 3, "the Brent North Sea crude contract for August delivery rose to $US145.01 a barrel" in Asian trade. London Brent crude reached a record of $145.75 a barrel, and Brent crude for August delivery peaked to a record $145.11 a barrel on London's ICE Futures Europe exchange, and to $144.44 a barrel on the NYMExchange. By midday in Europe, crude rose to $145.85 a barrel on the NYME while Brent crude futures rose to a trading record of $146.69 a barrel on the ICE Futures exchange.
On July 15, 2008, a bubble-bursting sell-off began after remarks by President Bush the previous day that the ban on oil drilling would be lifted. This precipitated an $8 drop, the biggest since the first US-Iraq war. By the end of the week, crude oil fell 11% to $128, also affected by easing of tensions between the US and Iran. By August 13, prices had fallen to $113 a barrel. By the middle of September, oil price fell below $100 for the first time in over six months, falling below $92 in the aftermath of the Lehman Brothers bankruptcy.
A stronger US dollar and a likely decline in European demand were suggested to be among the causes of the decline. By October 24, the price of crude dropped to $64.15, and closed at $60.77 on November 6. By the end of December, 2008, oil had bottomed out at $32.
On May 21, 2010, the price of oil had dropped in two weeks from $88 to $70 mainly due to concerns over how European countries would reduce budget deficits; if the European economy slowed down, this would mean less demand for crude oil. Also, if the European economic crisis caused the American economy to have problems, demand for oil would be reduced further. Other factors included the strong dollar and high inventories. According to the U.S. Energy Information Administration, gas prices nationwide averaged $2.91 on May 10, dropping to $2.79 two weeks later. The Deepwater Horizon oil spill was not a factor in gas prices since the well had not produced.
Prices rose back to $90/barrel in December 2010. The US average for a gallon of 87 octane regular unleaded averaged $3.00/gallon on December 23, sparking fear of a second recession if prices reached $100/barrel and $4.00/gallon gasoline, as forecasted for spring 2011. The price increases in December were based on global demand and the Arctic blasts affecting North America and Europe.
Political turmoil in Egypt, Libya, Yemen, and Bahrain drove oil prices to $95/barrel in late February 2011. A few days prior, oil prices on the NYMEX closed at $86. Oil prices topped at $103 on February 24 where oil production is curtailed to the political upheaval in Libya.
Oil supplies remained high, and Saudi Arabia assured an increase in production to counteract shutdowns. Still, the Mideast and North African crisis led to a rise in oil prices to the highest level in two years, with gasoline prices following. Though most Libyan oil went to Europe, all oil prices reacted. The average price of gasoline in the United States increased 6 cents to $3.17. On March 1, 2011, a significant drop in Libyan production and fears of more instability in other countries pushed the price of oil over $100 a barrel in New York trading, while the average price of gas reached $3.37. Despite Saudi promises, the sour type oil the country exported could not replace the more desirable sweet Libyan oil. On March 7, 2011, the average price of gas having reached $3.57, individuals were making changes in their driving.
The weakened U.S. Dollar resulted in a spike to $112/barrel with the national average of $3.74/gallon - with expectations of damaging the U.S. economy suggestive of a long-term recession. As of April 26, the national average was $3.87 - with a fear of $4/gallon as the nationwide average prior to the summer driving season.
The national average rose on May 5, 2011 for the 44th straight day, reaching $3.98. However, that same day, West Texas Intermediate crude fell below $100 a barrel, the lowest since March 16. This came after crude oil for June delivery reached $114.83 on May 2, the highest since September 2008, before closing at $97.18 on May 6, a day after dropping 9 percent, the most dramatic single-day drop in over two years. Gas prices fell slightly on May 6, and experts predicted $3.50 a gallon by summer.
In mid-June, West Texas Intermediate crude for July delivery fell nearly $2 to $93.01, the lowest price since February. The dollar was up and the euro and other currencies down, and the European economic crisis made investors concerned. London Brent crude fell 81 cents to $113.21. On June 15 the Energy Information Association said oil consumption was down 3.5 percent from a year earlier, but wholesale gasoline demand was up for the first time in several weeks. The price of gas on June 17 was $3.67.5 a gallon, 25.1 cents lower than a month earlier but 96.8 cents above a year earlier. On June 24, the price of gas was $3.62.8 and expected to go much lower due to the opening of the Strategic Petroleum Reserve. U.S. oil prices fell below $90 before rising again, and Brent crude fell two percent. However, on June 29, West Texas intermediate crude had risen to $94.96, almost $5 above the lowest point reached after the previous week's action. One reason was the falling dollar, as Greece appeared less likely to default on its debt; concern over the Greek debt crisis had caused falling oil prices. After another week, oil for August delivery had risen from $90.61 to $98.67 and gas prices were up five cents. Increased worldwide demand was one reason. Brent Crude remained high at $118.38 partly due to supply problems in Europe, including lower North Sea production and the continuing war in Libya.
On August 4, the price of oil dropped 6 percent to its lowest level in 6 months. On August 5, the price had dropped $8.82 in a week to $86.88 per barrel on the New York Mercantile Exchange. The same pessimistic economic news that caused stock prices to fall also decreased expected energy demand, and experts predicted a gas price drop of 35 cents per gallon from the average of $3.70. On August 8, oil fell over 6 percent, in its largest drop since May, to $81, its lowest price of the year. On September 24, oil reached $79.85, down 9 percent for the week, due to concerns about another recession and the overall world economy. The average price of gas was $3.51, with predictions of $3.25 by November, but it was below $3 in some markets.
During October, the price of oil rose 22 percent, the fastest pace since February, as worries over the U.S. economy decreased, leading to predictions of $4 by early 2012. As of November 8, the price reached $96.80. Gas prices were not following the increase, due to lower demand resulting from the economy, the normal decrease in travel, lower oil prices in other countries, and production of winter blends which cost less. The average rose slightly to $3.41 but predictions of $3.25 were made.
Shortages of oil could have resulted if Iran closed the Strait of Hormuz, through which one-fifth of exported oil travels, as a result of sanctions due to the country's nuclear policies. The price of oil stayed near $100 throughout January because of concerns over supplies, and the European debt situation. The average price of gas was $3.38 on January 20, up 17 cents from a month earlier. Another factor was planned closing of refineries in the U.S. and Europe due to lower demand. By early February, the national average was $3.48, though oil prices were at $98, the lowest in six weeks, and U.S. demand was the lowest since September 2001. On February 20, benchmark March crude oil reached $105.21, the highest in nine months. This came one day after Iran's oil ministry announced an end to sales to British and French companies; though this would have little actual impact on supplies, fears resulted in higher prices. Also, approval of the bailout plan for Greece was expected, and China's action to raise the money supply was likely to stimulate the economy. Brent crude was up 11 percent for the year to $119.58 on February 17, with cold weather in Europe and higher Third World demand, and West Texas Intermediate crude was up 19 percent to $103.24. The average price of gas was $3.53. On February 29, the average was $3.73. The average peaked at $3.94 early in April, and on April 24, it was $3.85 compared to $3.86 a year earlier; it had been two years since gas prices were lower than the previous year. Crude oil prices were down; West Texas Intermediate was $103.55 a barrel, down from over $107 late in March, and Brent Crude $118.16 after peaking above $128 in March. On May 7, benchmark U.S. crude reached $95.34, the lowest price of the year, after voters in France and Greece ousted government officials who would cut spending to solve the debt crisis. Benchmark oil in New York actually rose for two days straight early in June, to $84.29. With U.S. oil supplies the highest since 1990, gas reached $3.57 on June 5. After falling again to its lowest price since October 2011, Benchmark crude rose 5.8 percent to $82.18 on June 29, with Brent crude up 4.5 percent to $95.51. European bailout efforts included lending money to banks, decreasing likelihood of failures. Also, European countries decided not to buy Iranian oil. The price of gas was $3.35, the lowest since January 6. On July 17, Benchmark Crude reached $89.22 and Brent crude $104 after good economic news in the United States. Gas rose to $3.40.
On August 7, a California refinery fire contributed to a jump in oil futures. Other refinery problems, a pipeline leak, fears about Iran, the crisis in Syria, North Sea problems, and Tropical Storm Ernesto all contributed to a 20 percent jump in oil prices in six weeks. The price of gas reached $3.63 but was not expected to go much higher. Good economic news in the United States contributed to oil reaching its highest price since May on August 17, with Benchmark Crude reaching $96.01, while Brent crude fell slightly to $113.71.
Early in September, a mix of bad economic news from the United States and good economic news from Europe caused the price of oil to fall slightly. On September 4, Benchmark Crude reached $95.41, with Brent crude at $114.84. The price of gas went down slightly to $3.82 but was still the highest ever for Labor Day weekend. Hurricane Isaac contributed to a temporary spike in gas prices, but on September 12 gas once again rose, to $3.86, as refineries cut production prior to the switch from summer blend gasoline to winter blend. Benchmark Crude also reached its highest level since early May and continued to rise above $99 after Federal Reserve announcements of actions to improve the economy and the 2012 diplomatic missions attacks. Brent crude rose slightly to nearly $116. Early in October, the average gas price was $3.78 and falling, though still a record for the month. Late in the month, the average reached $3.62 after a 13-cent drop in a week, the most since November 2008. Brent crude was down $8 in the previous month. By the start of November, the average was $3.54, partly due to lower demand after Hurricane Sandy. Crude oil futures fell after Barack Obama was re-elected November 6. After Thanksgiving, lower U.S. oil inventories, good economic news in the United States and good news relating to the Greek bailout helped push Brent crude up to $111.04, and benchmark oil for January delivery to $87.92; benchmark oil reached $86.24 on November 28, and gas was $3.41.
On December 13, Brent crude was down to $109.20, while benchmark oil fell slightly due to U.S. fiscal cliff concerns and rose due to Federal Reserve efforts to help the U.S. economy, ending the day at $86.77. In mid-December, gas prices reached $3.25, the lowest for 2012. Oil was trading for between $84 and $90.
On January 17, with good economic news in the United States, Benchmark oil reached its highest level since September, going over $95. Brent crude rose above $110. Gas was at $3.29.
Refinery shutdowns led to a dramatic rise in gas prices. Late in February, gas was at $3.78, up 14 cents from a week earlier. On February 25, with European stock markets doing well, Benchmark crude for April rose above $94 after a significant drop the previous week due to news the Federal Reserve might end its stimulus efforts, making the dollar stronger. Brent crude was over $115. Two days later gas reached its highest point, $3.79 a gallon. By mid-April, with low demand expected due to negative economic news, gas was down to $3.56 as Brent crude fell to $103.04, its lowest price since July. With economic problems worldwide leading to low demand, gas prices fell 3 percent in April, the most in a month in ten years, to the lowest level for that month since 2010.
Before Memorial Day, when gas was $3.63, gas supplies fell even though oil supplies were the highest in 35 years. U.S. economic news was also negative. On May 30, Benchmark crude for July rose slightly to $93.61 after falling the previous day, and Brent crude fell slightly to $102.19. On June 5 the price of oil rose again with supplies lower. Benchmark crude rose above $94. The price of gas was $3.62. On June 12, the International Energy Agency said demand for oil would still rise in 2013, but not as much as previously believed due to the economy. Also, May OPEC production was the highest in seven months. Benchmark crude fell slightly to $95.31, and Brent crude rose to $103.27. On June 20, with the Federal Reserve stating that its stimulus program could end if the U.S. economy continued to improve, as well as economic problems in China, Benchmark crude fell below $97. Brent crude fell to $104.24.
On July 10, oil prices were the highest in more than a year as a result of lower supplies and trouble in Egypt. In the past week, Brent crude had climbed 7 percent to $108.51. Because too much oil was being produced for the infrastructure to handle it, West Texas Intermediate was lower than Brent crude for several years; it has returned to being consistent with Brent. On July 5 it reached $103.22. On July 19 with good economic news in the United States, Benchmark crude reached $108.05, while gas was $3.67, the highest on a Friday since March 22. Brent crude was at $108.07. Gas was $3.63 on August 1, though good economic news in the U.S., China and Europe meant oil was going up again after a decline the previous week. Benchmark crude reached $107.89, while Brent crude was $109.54. On August 16 Benchmark oil was $107.46 after six days of increases as Egypt's problems continued. The concern was access to the Suez Canal, which appears unlikely to be a problem but still concerns companies. Brent crude was $110.48 on August 19. On August 28 West Texas intermediate reached $110.10, the highest since May 2011, and Brent crude reached $116.61, its highest point since February 19, due to concern about U.S. involvement in Syria. Meanwhile, inventories in the United States had their biggest increase in four months. Benchmark crude rose to $107.56 on September 11 due to lower supplies after dropping due to hopes for a peaceful Syria solution; Brent crude rose to $111.50.
Gas was $3.59 at the start of the month, but at the end of September, the price of gas was $3.39, the lowest for the time of year since 2010. The New York Mercantile Exchange price on September 27 was $102.87. Refineries had no hurricanes or other problems. Benchmark crude fell to $103.31 on October 3 after the U.S. government shutdown, and Brent crude was $109. On October 21, Benchmark crude was $99.22, the first time below $100 since July. Higher supplies and fewer threats from the Middle East were the reasons. Brent crude was $109.64 and gas reached $3.35. On November 13, Brent crude reached $107.12 and was $13.24 higher than West Texas Intermediate, the largest difference since April, due to trouble in Libya and sanctions against Iran. On November 25, Benchmark crude decreased to $93.92 while Brent crude reached $110.41 after the agreement regarding Iran's nuclear program. On December 16, Benchmark crude rose to $97.44 and Brent crude reached $110.53 with good economic news from Europe and more Libya trouble. Gas was $3.23, three cents higher than a month earlier. On December 27, due to a better economy in the United States leading to higher demand, oil closed about $100 for the first time since October. Gas was $3.27, two cents below a year earlier.
On January 2, Benchmark crude fell by the most in one day since November 2012 to close at $95.44. Brent crude was $107.78. Gas was $3.33. With the Iran agreement and increased production from Libya and the North Sea, Benchmark oil was around $92 on January 13 and Brent crude was $105.98. After good economic news from Japan, Benchmark crude fell slightly from its highest close of 2014, $98.23 on January 30. Brent crude fell to $107.25. The difference between the two fell below $10 for the first time since November, partly due to cold weather in the United States which resulted in high heating oil demand. Early in February gas was $3.27. Cold weather led to the price of oil staying above $100 for most of February, but lower prices were expected. With United States fourth quarter economic growth expected to be lower than an early estimate, Benchmark crude fell slightly on February 27 to $102.40, with Brent crude reaching $108.61. On March 24, due to the dispute over Crimea, problems in Libya, and the Houston Ship Channel collision, Benchmark crude rose above $100 and Brent crude rose to $107.41. Economic problems in China kept prices from going even higher. Later in the week, good economic news from the United States, lower oil supplies in Oklahoma and a force majeure by Shell Nigeria pushed prices slightly higher, to $102.12 for Benchmark crude and $108.29 for Brent. On April 7, Benchmark crude fell below $101 and Brent crude fell to $105.64 with news that Libya might open more terminals in May, but more Ukraine problems pushed the prices back up on April 8. Gas was $3.59, matching the level in 2013.
Continued Ukraine problems pushed oil higher on April 24, with Benchmark crude at $101.94 and Brent crude at $110.33, though an April 23 report said U.S. oil supplies were higher than expected. The price of gas was $3.68.5, the highest since March 2013. On April 30, Benchmark crude dropped below $100 for the first time in three weeks as oil supplies continued to rise and the unusually cold winter resulted in negative U.S. economic news. Gas was up 14 cents for the month, the most in three years. More Ukraine trouble pushed Benchmark crude above $100 and Brent crude over $108 on May 12, and further problems in Libya helped push Benchmark crude over $102 and Brent crude over $110 by May 15, though negative economic news in the U.S. and an unexpected increase in oil stockpiles pushed Benchmark crude back down temporarily. Continued concerns over Ukraine and Libya pushed oil back above $104. The price of gas was $3.65.
Trouble in Iraq resulted in higher prices for oil and gas in June. West Texas crude reached $106 and Brent crude $115.75. At the end of the month Benchmark crude was just above $105 while Brent crude fell below $113. The price of gas was $3.66.
After three weeks of going down, U.S. crude fell below $100 for the first time since May on July 15. However, with Middle East and Ukraine problems sending oil higher, Benchmark crude finished July 18 just above $103, with Brent crude staying above $107. With low demand and plentiful supplies, and despite good economic news from China and the United States, Brent crude fell below $107 on July 24, and U.S. crude dropped to $102.10. On July 28, gas was $3.52, down five cents from a week earlier, due to refiners cutting prices. Two weeks later gas was $3.48, less than a year earlier. And on August 14, light sweet oil was $95.58, the lowest since January, while Brent crude reached $102.01, the lowest since June, after falling the most in one day since January. Production in Libya was up, and economic slowdowns were expected in Europe and China, making even lower prices likely.
As of Labor Day, gas was $3.41, 18 cents lower than in 2013. Low demand and high North American production cancelled out effects of troubles in the Middle East and Ukraine. West Texas crude was below $94 on August 27 and Brent crude below $103. On October 16, West Texas crude fell below $80 for the first time in more than two years, while Brent crude reached $82.60, the lowest since November 2010. OPEC Members were not expected to act as increases in the U.S. supply resulting from high oil shale production added to a worldwide surplus. On October 31, the average price of gas reached $3 and was expected to go below that figure for the first time since December 2010. Demand for oil was down and there were many new sources. United States oil production was up 70 percent since 2008, and Iraq and Canada were producing more. According to the Lundberg survey released December 7, gas was down 12 cents from two weeks earlier to $2.72. Demand was low while production was high, and the strong dollar contributed. With demand low in China and Europe and OPEC deciding not to cut back, West Texas Intermediate reached $63.50 on December 8, the lowest since July 2009, while Brent crude reached $66.90, a level not seen since October 2009. After Saudi Arabia oil minister Ali Al-Naimi said OPEC members could not cut production on their own, oil prices rose slightly December 18 but finished the day lower with Benchmark crude at $54.11 and Brent crude $59.27, both the lowest since May 2009. Gas was $2.49 a gallon. Days later gas was $2.38, the lowest in five years, after 89 straight days of going down, the longest continuous decline ever according to AAA. The price of oil was down 50 percent since April, while gas had fallen 36 percent. Economic problems in Europe and Asia, high gas mileage, a strong dollar, higher U.S. production and no action by OPEC have been credited.
On January 16, Brent crude rose as high as $50.16 before falling back, and the International Energy Agency said production was down due to lower prices and higher prices were likely late in 2015.  West Texas Intermediate, down 10 percent for the month, closed at $48.48 on January 14 after closing at $45.89 the previous day. Gas was $2.12.
From January 30 to February 3, oil rose 20 percent, but on February 4, U.S. crude futures fell 8.7 percent to $48.45, the most in one day since November 28, 2014. Brent crude fell from $59 to $54 two weeks after reaching $45. U.S. inventories were the highest since 1982, while the dollar was recovering from "its worst day in more than a year."
Although inventory remained high, Brent crude reached its highest price of 2015 on February 17, closing at $62.53 after reaching $63. Problems in the Middle East, especially Libya, contributed to the rise. Fighting in Ukraine was also a factor.
At the end of February, with refineries changing to summer blend, the price of gas was $2.37, up from $2.03 in January. Other factors included an explosion at a Torrance, California refinery and a strike involving steel workers at 20 refineries.
On March 13, oil declined 5 percent for a total drop of 10 percent for the week. Benchmark crude reached $45.16 and Brent crude was $56.24. Supplies continued to increase and the price was expected to fall until changes by refineries for summer. Gas reached $2.46 March 7 but fell to $2.44 a week later. U.S. inventories were the highest since records had been kept, but on March 18, with the Federal Reserve indicating interest rates would not rise quickly, oil prices increased 6 percent.
Brent crude rose 16 percent in April, reaching $64.95, its highest price for 2015, on April 16. U.S. crude was $56.62 on April 17. Reasons were a drop in expected shale oil production in the United States and the war in Yemen. Gas was $2.41, up a penny in a week.
On May 5, gas reached $2.63 after rising for 19 days; gas was going up faster than oil, which reached its highest 2015 price, $61.10 for U.S. crude and $68.40 for Brent crude, before settling at $60.40 and $67.52 respectively. The dollar was lower but different sources conflicted over whether U.S. inventories were down for the first time in 2015, or up as they had been.
