Crude oil inputs to Mexico’s petroleum refineries declined for the fifth consecutive year in 2018, falling to nearly 600,000 barrels per day (b/d), a 50% drop from 2013 levels. This decline in crude oil processing has coincided with a decrease in domestic production of the light crude oil that the country’s refineries are better suited to process. Mexico has increasingly relied on imports of petroleum products from the United States to satisfy domestic demand.
Petróleos Mexicanos (Pemex), Mexico’s national oil company, owns and operates the country’s six petroleum refineries, which have a combined atmospheric crude oil distillation capacity of about 1.6 million b/d. On an aggregate basis, performance at Pemex refineries has declined over the past five years after maintaining an average refinery utilization rate near or above 75% between 1990 and 2013. By 2018, the utilization rate of Mexico’s refinery network fell to less than 40%.
Pemex’s refineries are mostly configured to process light crude oil. Of its six refineries, three (Minatitlan, Cadereyta, Madero) are equipped with coker units to produce lower-sulfur gasoline from heavy crude oil. The 35% decrease in Mexican light crude oil production between 2013 and 2018 has resulted in limitations on crude oil refinery inputs. Inputs of light crude oil to Pemex refineries fell below 400,000 b/d in 2018, about a 50% reduction from 2013 levels.
Refineries require periodic maintenance to ensure optimal operation of processing units that refine crude oil into petroleum products such as motor gasoline and diesel. Crude oil inputs at Pemex refineries since 2014 have been further constrained by operational issues associated with the company’s refineries.
Pemex maintains control over much of Mexico’s petroleum product imports and distribution. Declines in domestic production of liquid transportation fuels have increased Mexico’s reliance on foreign sources of refined petroleum products. Pemex imports of motor gasoline increased about 230,000 b/d between 2013 and 2018, offsetting similar declines in domestic production at Pemex refineries.

Mexican imports from the United States have helped to offset a large share of Pemex’s shortfall in motor gasoline production, supplying about 535,000 b/d in 2018, more than double the level of imports in 2013. Mexico receives the largest share of U.S. motor gasoline exports, with much of the remainder destined for Central and South American countries.
U.S. refineries along the Gulf Coast are able to process heavy Mexican crude oil blends with a high yield of finished, low-sulfur motor gasoline. Pemex currently obtains some of its motor gasoline from the United States through its joint venture with Shell at the 340,000 b/d refinery in Deer Park, Texas. The joint venture, which was recently extended through 2033, includes an agreement for Pemex to provide a share of heavy crude oil in exchange for finished petroleum products.
In September 2018, the Mexican government announced an initiative called the National Refining Plan to help Mexico achieve energy independence by 2022. The plan includes upgrades and reconfigurations at Pemex’s six refineries, as well as construction in Dos Bocas of a seventh refinery, which is designed to process 340,000 b/d of heavy crude oil. If achieved, Pemex refineries would be able to process 1.86 million b/d of crude oil to produce an estimated 781,000 b/d of motor gasoline and 560,000 b/d of diesel fuel.

Recent headlines on the oil industry have focused squarely on the upstream side: the amount of crude oil that is being produced and the resulting effect on oil prices, against a backdrop of the Covid-19 pandemic. But that is just one part of the supply chain. To be sold as final products, crude oil needs to be refined into its constituent fuels, each of which is facing its own crisis because of the overall demand destruction caused by the virus. And once the dust settles, the global refining industry will look very different.
Because even before the pandemic broke out, there was a surplus of refining capacity worldwide. According to the BP Statistical Review of World Energy 2019, global oil demand was some 99.85 mmb/d. However, this consumption figure includes substitute fuels – ethanol blended into US gasoline and biodiesel in Europe and parts of Asia – as well as chemical additives added on to fuels. While by no means an exact science, extrapolating oil demand to exclude this results in a global oil demand figure of some 95.44 mmb/d. In comparison, global refining capacity was just over 100 mmb/d. This overcapacity is intentional; since most refineries do not run at 100% utilisation all the time and many will shut down for scheduled maintenance periodically, global refining utilisation rates stand at about 85%.
Based on this, even accounting for differences in definitions and calculations, global oil demand and global oil refining supply is relatively evenly matched. However, demand is a fluid beast, while refineries are static. With the Covid-19 pandemic entering into its sixth month, the impact on fuels demand has been dramatic. Estimates suggest that global oil demand fell by as much as 20 mmb/d at its peak. In the early days of the crisis, refiners responded by slashing the production of jet fuel towards gasoline and diesel, as international air travel was one of the first victims of the virus. As national and sub-national lockdowns were introduced, demand destruction extended to transport fuels (gasoline, diesel, fuel oil), petrochemicals (naphtha, LPG) and power generation (gasoil, fuel oil). Just as shutting down an oil rig can take weeks to complete, shutting down an entire oil refinery can take a similar timeframe – while still producing fuels that there is no demand for.
Refineries responded by slashing utilisation rates, and prioritising certain fuel types. In China, state oil refiners moved from running their sites at 90% to 40-50% at the peak of the Chinese outbreak; similar moves were made by key refiners in South Korea and Japan. With the lockdowns easing across most of Asia, refining runs have now increased, stimulating demand for crude oil. In Europe, where the virus hit hard and fast, refinery utilisation rates dropped as low as 10% in some cases, with some countries (Portugal, Italy) halting refining activities altogether. In the USA, now the hardest-hit country in the world, several refineries have been shuttered, with no timeline on if and when production will resume. But with lockdowns easing, and the summer driving season up ahead, refinery production is gradually increasing.
But even if the end of the Covid-19 crisis is near, it still doesn’t change the fundamental issue facing the refining industry – there is still too much capacity. The supply/demand balance shows that most regions are quite even in terms of consumption and refining capacity, with the exception of overcapacity in Europe and the former Soviet Union bloc. The regional balances do hide some interesting stories; Chinese refining capacity exceeds its consumption by over 2 mmb/d, and with the addition of 3 new mega-refineries in 2019, that gap increases even further. The only reason why the balance in Asia looks relatively even is because of oil demand ‘sinks’ such as Indonesia, Vietnam and Pakistan. Even in the US, the wealth of refining capacity on the Gulf Coast makes smaller refineries on the East and West coasts increasingly redundant.
Given this, the aftermath of the Covid-19 crisis will be the inevitable hastening of the current trend in the refining industry, the closure of small, simpler refineries in favour of large, complex and more modern refineries. On the chopping block will be many of the sub-50 kb/d refineries in Europe; because why run a loss-making refinery when the product can be imported for cheaper, even accounting for shipping costs from the Middle East or Asia? Smaller US refineries are at risk as well, along with legacy sites in the Middle East and Russia. Based on current trends, Europe alone could lose some 2 mmb/d of refining capacity by 2025. Rising oil prices and improvements in refining margins could ensure the continued survival of some vulnerable refineries, but that will only be a temporary measure. The trend is clear; out with the small, in with the big. Covid-19 will only amplify that. It may be a painful process, but in the grand scheme of things, it is also a necessary one.

Note: All prices except West Texas Intermediate (Cushing) are spot prices.
The New York Mercantile Exchange (NYMEX) front-month futures contract for West Texas Intermediate (WTI), the most heavily used crude oil price benchmark in North America, saw its largest and swiftest decline ever on April 20, 2020, dropping as low as -$40.32 per barrel (b) during intraday trading before closing at -$37.63/b. Prices have since recovered, and even though the market event proved short-lived, the incident is useful for highlighting the interconnectedness of the wider North American crude oil market.
Changes in the NYMEX WTI price can affect other price markers across North America because of physical market linkages such as pipelines—as with the WTI Midland price—or because a specific price is based on a formula—as with the Maya crude oil price. This interconnectedness led other North American crude oil spot price markers to also fall below zero on April 20, including WTI Midland, Mars, West Texas Sour (WTS), and Bakken Clearbrook. However, the usefulness of the NYMEX WTI to crude oil market participants as a reference price is limited by several factors.
Source: U.S. Energy Information Administration
First, NYMEX WTI is geographically specific because it is physically redeemed (or settled) at storage facilities located in Cushing, Oklahoma, and so it is influenced by events that may not reflect the wider market. The April 20 WTI price decline was driven in part by a local deficit of uncommitted crude oil storage capacity in Cushing. Similarly, while the price of the Bakken Guernsey marker declined to -$38.63/b, the price of Louisiana Light Sweet—a chemically comparable crude oil—decreased to $13.37/b.
Second, NYMEX WTI is chemically specific, meaning to be graded as WTI by NYMEX, a crude oil must fall within the acceptable ranges of 12 different physical characteristics such as density, sulfur content, acidity, and purity. NYMEX WTI can therefore be unsuitable as a price for crude oils with characteristics outside these specific ranges.
Finally, NYMEX WTI is time specific. As a futures contract, the price of a NYMEX WTI contract is the price to deliver 1,000 barrels of crude oil within a specific month in the future (typically at least 10 days). The last day of trading for the May 2020 contract, for instance, was April 21, with physical delivery occurring between May 1 and May 31. Some market participants, however, may prefer more immediate delivery than a NYMEX WTI futures contract provides. Consequently, these market participants will instead turn to shorter-term spot price alternatives.
Taken together, these attributes help to explain the variety of prices used in the North American crude oil market. These markers price most of the crude oils commonly used by U.S. buyers and cover a wide geographic area.
