Brent and West Texas Intermediate (WTI) are two globally recognised oil benchmarks. When market participants refer to the price of oil, they typically refer to one or the other or both. But despite having quite similar chemical properties, there are important distinguishing features between the two. Financial markets recognise these differences and, as a result, price the two differently. The two benchmarks have contrasting features in terms of where the oil is produced, how it is stored and transported and the way it is traded in international markets. These differences not only explain the historical price discrepancy between the two, but also help us understand why the two have behaved differently during the coronavirus pandemic and the ensuing market volatility. This article will contrast the distinguishing features between the two and, after developing a new lens to view the two benchmarks, replay the recent episode when WTI prices crashed into negative territory. The article will conclude by outlining the forces which will shape the fluid commodity going forward.

Same, same, but different

In ‘A tale of Two Cities’ by Charles Dickens, Sydney Carton sacrifices his life to save Charles Darnay, who is married to the woman Carton loves, by taking his place in prison moments before he is taken to the guillotine during the French revolution. He is able to pull off this selfless act of bravery thanks to the uncanny resemblance between him and Darnay. Similarly, most people would not be able to tell the difference if a barrel of WTI was replaced with one for Brent given the likeness between the two. Both Brent and WTI are referred to as light and sweet. They are ‘light’ in terms of the American Petroleum Institute (API) gravity. Having an API gravity greater than 10 makes them light and allows them to float on water, while an API gravity of less than 10 would have caused them to sink. Similarly, both have low sulphur content making them ‘sweet’ and easy to refine (See Figure 01).

But while Carton and Darnay looked alike, they were distinctly different individuals. Brent and WTI too, despite their resemblance, have their disparities. Brent Crude is extracted from the North Sea. Oil production from Europe, Africa and the Middle East tends to use Brent as its main benchmark. This accounts for around two-thirds of internationally traded crude oil. The Organisation of the Petroleum Exporting countries (OPEC), an intergovernmental organisation comprising 13 key oil producing countries as well as their 10 partner countries (collectively referred to as OPEC+), also typically use Brent as their oil price benchmark. In contrast, WTI is sourced primarily from Texas and most oil production in the US uses WTI as its main benchmark.

Brent and WTI have always traded at different prices giving rise to the Brent – WTI spread (Figure 02). Purely in terms of quality, WTI has a slight edge over Brent on account of its lower sulphur content making it moderately ‘sweeter’ and thus easier to refine. For this reason, WTI ought to theoretically trade at a premium over Brent. For a large part of the first decade of this century, WTI did indeed trade at a premium, i.e. the Brent – WTI spread was negative. Over the last decade however, the shale revolution in the US has brought large volumes of oil into the market making the US one of the largest oil producers in the world. The shale revolution refers to a combination of technological improvements and financial infrastructure enabling the US to produce oil from low-permeable shale, sandstone and carbonate rock formations in larger quantities than ever before. The shale oil industry has grown rapidly since 2011 and accounted for 63% of total US crude oil production in 2019 (according to the US Energy Information Administration). In line with economic principles of demand and supply, as the total volume of oil production increased in the US, this put downward pressure on WTI. The Brent – WTI spread has generally been positive in the last decade.

Another reason for the Brent – WTI spread is the logistical challenge for the US to transport oil from landlocked production hubs through a network of pipelines and to ship it overseas. This impinges on the overseas demand for oil from the US (WTI). In contrast, Brent is produced at or closer to sea making it easier for it to reach its overseas destinations. The US is however investing heavily in its pipeline infrastructure to enable it to send large vessels of oil from its shores to international buyers. Several such infrastructure projects are expected to be completed by 2021-2022 when we might see an increase in demand for WTI and thus a narrowing of its spread with Brent.

The historic WTI crash

The explanation above of the spread between the two benchmarks omits any discussion about the unprecedented spike on 20 April 2020. This section will unravel the story behind the anomalous occurrence.

On Monday 20 April 2020, markets witnessed a historic crash in WTI prices (Figure 03). The crash occurred a day before the active Nymex WTI futures contract was due to expire. This contract, meant to deliver oil between 01 May and 31 May, crashed into negative territory as oil storage in the US became very tight. With the coronavirus pandemic causing considerable oil demand destruction putting entire countries in lockdown and bringing economic activity to a grinding halt, the reduction in oil production was not enough to balance the market creating a supply glut. The main delivery and settlement point in Cushing, Oklahoma was approaching its storage limit with any additional capacity likely already leased out or earmarked for other purposes. This acute pressure, so close to contract expiry at the point where contracts settle, contributed to the negative price. Those taking physical delivery from the expiring futures contract were being paid to take the oil and find a place to store it. The May contract expired the following day in slightly positive territory. When the June contract became the active contract upon the May contract’s expiry, prices recovered further as the issue of June deliveries creating the same problem was less worrying, at least at that point.

But Brent did not endure a similar crash. The main reason for this is that WTI, traded on the New York Mercantile Exchange (NYMEX), is a deliverable futures contract. Thus, upon expiry, the holder of the futures contract takes delivery of the underlying, i.e. barrels of oil. Brent however, traded on the Intercontinental Exchange (ICE), has a cash settlement procedure whereby the holder of the futures contract need not take delivery of the underlying upon expiry. Therefore, storage issues create a more direct risk to investors in WTI futures.

Outside of this idiosyncrasy pertaining to futures trading, the two benchmarks generally move with a high degree of correlation (Figure 04). At the peak of the coronavirus pandemic’s acceleration in April, a third of global oil demand was wiped out. Soon thereafter, major oil producers Saudi Arabia and Russia engaged in a price war. This created a double shock for oil as the suppliers opened the floodgates at a time when demand had just crashed. Both benchmarks experienced severe price weakness. But as policy decisions from OPEC+ can be expected to impact Brent prices more than WTI, the deal reached by the group at the start of April to cut suppliesprovided slightly more cushioning to Brent.

What happens next?

With a deeper understanding of the drivers of the two benchmarks, historic and recent price behaviour makes more sense. But the all-important question is, “what happens next?”. The fate of oil prices rests heavily on how quickly the world can overcome the pandemic and get the economic engines firing again. Volatility in oil prices may persist in the coming weeks, or even months, until uncertainty with regards to the pandemic and lockdowns diminishes. The relative price behaviour of WTI and Brent during this period will depend on the degree to which producers in the US and OPEC+ cut supplies to balance the market.

We however hope to paint a more optimistic picture of the world in the second half of this year. Oil prices may not recover quickly to where they were in February this year due to an overhang of excess supply, a fractured OPEC+ and a dented global economic engine. Nonetheless, after all the pain, the world will eventually return to some semblance of normalcy. Manufacturers will switch their machines on again, cars will return to the roads and aeroplanes will return to the skies. Once again, oil is expected to be in demand. And while one protagonist had to sacrifice himself to save the other in the tale told by Dickens, we expect both mainstays from the tale of two benchmarks to rise again when the crisis is over.

A muted price reaction. Market looks relaxed, but it is still on edge waiting for what Iran will do

Brent crossed the 80-line this morning but quickly fell back assigning limited probability for Iran choosing to close the Strait of Hormuz. Brent traded in a range of USD 70.56 – 79.04/b last week as the market fluctuated between ”Iran wants a deal” and ”US is about to attack Iran”. At the end of the week though, Donald Trump managed to convince markets (and probably also Iran) that he would make a decision within two weeks. I.e. no imminent attack. Previously when when he has talked about ”making a decision within two weeks” he has often ended up doing nothing in the end. The oil market relaxed as a result and the week ended at USD 77.01/b which is just USD 6/b above the year to date average of USD 71/b.

Brent jumped to USD 81.4/b this morning, the highest since mid-January, but then quickly fell back to a current price of USD 78.2/b which is only up 1.5% versus the close on Friday. As such the market is pricing a fairly low probability that Iran will actually close the Strait of Hormuz. Probably because it will hurt Iranian oil exports as well as the global oil market.

It was however all smoke and mirrors. Deception. The US attacked Iran on Saturday. The attack involved 125 warplanes, submarines and surface warships and 14 bunker buster bombs were dropped on Iranian nuclear sites including Fordow, Natanz and Isfahan. In response the Iranian Parliament voted in support of closing the Strait of Hormuz where some 17 mb of crude and products is transported to the global market every day plus significant volumes of LNG. This is however merely an advise to the Supreme leader Ayatollah Ali Khamenei and the Supreme National Security Council which sits with the final and actual decision.

No supply of oil is lost yet. It is about the risk of Iran closing the Strait of Hormuz or not. So far not a single drop of oil supply has been lost to the global market. The price at the moment is all about the assessed risk of loss of supply. Will Iran choose to choke of the Strait of Hormuz or not? That is the big question. It would be painful for US consumers, for Donald Trump’s voter base, for the global economy but also for Iran and its population which relies on oil exports and income from selling oil out of that Strait as well. As such it is not a no-brainer choice for Iran to close the Strait for oil exports. And looking at the il price this morning it is clear that the oil market doesn’t assign a very high probability of it happening. It is however probably well within the capability of Iran to close the Strait off with rockets, mines, air-drones and possibly sea-drones. Just look at how Ukraine has been able to control and damage the Russian Black Sea fleet.

What to do about the highly enriched uranium which has gone missing? While the US and Israel can celebrate their destruction of Iranian nuclear facilities they are also scratching their heads over what to do with the lost Iranian nuclear material. Iran had 408 kg of highly enriched uranium (IAEA). Almost weapons grade. Enough for some 10 nuclear warheads. It seems to have been transported out of Fordow before the attack this weekend.

The market is still on edge. USD 80-something/b seems sensible while we wait. The oil market reaction to this weekend’s events is very muted so far. The market is still on edge awaiting what Iran will do. Because Iran will do something. But what and when? An oil price of 80-something seems like a sensible level until something do happen.

Very relaxed at USD 75/b. Risk barometer will likely fluctuate to higher levels with Brent into the 80ies or higher coming 2-3 weeks

Brent rallied 12% last week. But closed the week below USD 75/b and it is still there. Very relaxed. Brent crude rallied 12% to USD 78.5/b in the early hours of Friday as Israel attacked Iran. The highest level since 27 January this year. The level didn’t hold and Brent closed the day at USD 74.23/b which was up 5.7% on the day and 11.7% on the week. On Friday it was still very unclear how extensive and lasting this war between Iran and Israel would be. Energy assets in Iran had still not been touched and Iran had not targeted other Middle East countries’ energy assets or US military bases in the region. As such, the Brent crude closed the week comfortably at around USD 75/b. Which one cannot argue is very much of a stressed price level.

Israel is targeting Iran’s domestic energy infrastructure. Not its energy export facilities. For now. Over the weekend Israel has widened its targets to include fuel depots in Tehran, refineries supplying Iran domestically and also a processing plant at Iran’s South Pars gas field – the world’s largest. So far it appears that Israel has refrained from hurting Iranian oil and gas export facilities. Maybe adhering to Trump’s whish of low oil prices. Trump has been begging for a lower oil price. Would be very frustrating for him if Israel started to blow up Iran’s export facilities. Focus instead looks to be on Iran’s domestic energy supply and infrastructure. To weaken and disable the operations of Iran as a country while leaving Iran’s energy export facilities intact for now at least. That is probably why Brent crude this morning is only trading at USD 74.9/b with little change from Friday. An incredible relaxed price level given what is going on in the Middle East.

Israel seems to try to do to Iran what Israel recently did to Lebanon. Israel now seems to have close to total control of the Iranian air space. So called ”Air Supremacy” something which is rarely achieved according to Phillips P. O’Brian (see comment on this below with link). This is giving Israel close to total freedom in the airspace over Iran. Israel now seems to try to do to Iran what Israel recently did to Lebanon. Take out military and political commanders. Take out the air defenses. Then grind the rest of its defensive capacities to the ground over some time.

Continuous pressure. No rest. No letting up for several weeks seems likely. The current situation is a very rare opportunity for Israel to attack Iran with full force. Hamas in Gaza, Hezbollah in Lebanon, Iranian strongholds in Syria, are all severely weakened or disabled. And now also Air Supremacy of the airspace over Iran. It is natural to assume that Israel will not let this opportunity pass. As such it will likely continue with full force over several weeks to come, at least, with Israel grinding down the rest of Iran’s defensive capabilities and domestic energy supply facilities as far as possible. Continuous pressure. No rest. No letting up.

What to do with Fordow? Will Iran jump to weapons grade uranium? The big question is of course Iran’s nuclear facilities. Natanz with 16,000 enrichment centrifuges was destroyed by Israel on Friday. It was only maximum 20 meters below ground. It was where Iran had mass enrichment to low enrichment levels. Fordow is a completely different thing. It is 500 meters deep under a mountain. It is where enrichment towards weapons grade Uranium takes place. Iran today has 408 kg of highly enriched uranium (IAEA) which can be enriched to weapons grade. It is assumed that Iran will only need 2-3 days to make 25 kg of weapons grade uranium and three weeks to make enough for 9 nuclear warheads. How Israel decides to deal with Fordow is the big question. Ground forces? Help from the US?

Also, if Iran is pushed to the end of the line, then it might decide to enrich to weapons grade which again will lead to a cascade of consequences.

Brent is extremely relaxed at USD 75/b. But at times over coming 2-3 weeks the risk barometer will likely move higher with Brent moving into the 80ies or higher. The oil price today is extremely relaxed with the whole thing. Lots of OPEC+ spare capacity allows loss of Iranian oil exports. Israeli focus on Iran’s domestic energy systems rather than on its exports facilities is also soothing the market. But at times over the coming two, three weeks the risk barometer will likely move significantly higher as it might seem like the situation in the Middle East may move out of control. So Brent into the 80ies or higher seems highly likely in the weeks to come. At times at least. And if it all falls apart, the oil price will of course move well above 100.

Phillips P. OBrien on ”Air Supremacy” (embedded link): Air power historian Philip Meilinger: ”Air Superiority is defined as being able to conduct air operations “without prohibitive interference by the opposing force.” Air Supremacy goes further, wherein the opposing air force is incapable of effective interference.”

Thus, air supremacy is an entirely different beast from air superiority. It occurs when one power basically controls the skies over an enemy, and can operate practically anywhere/time that it wants without much fear of enemy interference in its operations.

The US had Air Supremacy over Germany in the second World War, but only at the very end when it was close to over. It only had Air Superiority in the Vietnam war, but not Supremacy. During Desert Storm in 1990-1991 however it did have Supremacy with devastating consequences for the enemy. (last paragraph is a condensed summary).

Brent needs to fall to USD 58/b to make cheating unprofitable for Kazakhstan

Brent jumping 2.4% as OPEC+ lifts quota by ”only” 411 kb/d in July. Brent crude is jumping 2.4% this morning to USD 64.3/b following the decision by OPEC+ this weekend to lift the production cap of ”Voluntary 8” (V8) by 411 kb/d in July and not more as was feared going into the weekend. The motivation for the triple hikes of 411 kb/d in May and June and now also in July has been a bit unclear: 1) Cheating by Kazakhstan and Iraq, 2) Muhammed bin Salman listening to Donald Trump for more oil and a lower oil price in exchange for weapons deals and political alignments in the Middle East and lastly 3) Higher supply to meet higher demand for oil this summer. The argument that they are taking back market share was already decided in the original plan of unwinding the 2.2 mb/d of V8 voluntary cuts by the end of 2026. The surprise has been the unexpected speed with monthly increases of 3×137 kb/d/mth rather than just 137 kb/d monthly steps.

No surplus yet. Time-spreads tightened last week. US inventories fell the week before last. In support of point 3) above it is worth noting that the Brent crude oil front-end backwardation strengthened last week (sign of tightness) even when the market was fearing for a production hike of more than 411 kb/d for July. US crude, diesel and gasoline stocks fell the week before last with overall commercial stocks falling 0.7 mb versus a normal rise this time of year of 3-6 mb per week. So surplus is not here yet. And more oil from OPEC+ is welcomed by consumers.

Saudi Arabia calling the shots with Russia objecting. This weekend however we got to know a little bit more. Saudi Arabia was predominantly calling the shots and decided the outcome. Russia together with Oman and Algeria opposed the hike in July and instead argued for zero increase. What this alures to in our view is that it is probably the cheating by Kazakhstan and Iraq which is at the heart of the unexpectedly fast monthly increases. Saudi Arabia cannot allow it to be profitable for the individual members to cheat. And especially so when Kazakhstan explicitly and blatantly rejects its quota obligation stating that they have no plans of cutting production from 1.77 mb/d to 1.47 mb/d. And when not even Russia is able to whip Kazakhstan into line, then the whole V8 project is kind of over.

Is it simply a decision by Saudi Arabia to unwind faster altogether? What is still puzzling though is that despite the three monthly hikes of 411 kb/d, the revival of the 2.2 mb/d of voluntary production cuts is still kind of orderly. Saudi Arabia could have just abandoned the whole V8 project from one month to the next. But we have seen no explicit communication that the plan of reviving the cuts by the end of 2026 has been abandoned. It may be that it is simply a general change of mind by Saudi Arabia where the new view is that production cuts altogether needs to be unwinded sooner rather than later. For Saudi Arabia it means getting its production back up to 10 mb/d. That implies first unwinding the 2.2 mb/d and then the next 1.6 mb/d.

Brent would likely crash with a fast unwind of 2.2 + 1.6 mb/d by year end. If Saudi Arabia has decided on a fast unwind it would meant that the group would lift the quotas by 411 kb/d both in August and in September. It would then basically be done with the 2.2 mb/d revival. Thereafter directly embark on reviving the remaining 1.6 mb/d. That would imply a very sad end of the year for the oil price. It would then probably crash in Q4-25. But it is far from clear that this is where we are heading.

Brent needs to fall to USD 58/b or lower to make it unprofitable for Kazakhstan to cheat. To make it unprofitable for Kazakhstan to cheat. Kazakhstan is currently producing 1.77 mb/d versus its quota which before the hikes stood at 1.47 kb/d. If they had cut back to the quota level they might have gotten USD 70/b or USD 103/day. Instead they choose to keep production at 1.77 mb/d. For Saudi Arabia to make it a loss-making business for Kazakhstan to cheat the oil price needs to fall below USD 58/b ( 103/1.77).
