Going green? The unexpected investments helping to reduce vehicle emissions

Globally about 15% of the world’s Greenhouse Gas (GHG) emissions come from the transportation sector. Despite improving fuel efficiency in cars over the past seven decades, the fact that more people in the world use cars means that global emissions from the transport sector continue to rise. However, pollution abatement equipment can help reduce emissions from cars. Autocatalysts are a key technology in this regard. 

Platinum and palladium in autocatalysts

An autocatalyst is a device installed in internal combustion engine cars that converts harmful pollutants into safer gases. Platinum group metals (PGM) including platinum, palladium and rhodium are key ingredients in the autocatalysts that generate this chemical conversion. Autocatalysts were first introduced in the mid-1970s and today, are used in almost all internal combustion engine vehicles (including hybrid vehicles). In addition, fuel cell vehicles also use platinum (not palladium or rhodium) as the main catalyst in the reactions to produce electricity and water from hydrogen fuel and water. 

How important are autocatalysts for PGM demand?   

In 2019, automobiles accounted for 34% of platinum demand and 84% of palladium demand. So, the auto industry is the key driver of demand for both platinum and palladium.  

Vehicle sales versus regulation 

Tightening emission regulations generally increases the demand for the platinum group metals. Demand for platinum group metals will also vary with the volume of vehicle sales. Historically it has been emission regulation that has had a greater influence on demand. According to World Platinum Investment Council’s calculations, global vehicle sales between 1990 and 2019 rose by 1.6 times whereas the combined demand for platinum, palladium and rhodium in cars rose by 6.2 times. The fact that the rise in automobile platinum group metal demand was more than the increase in car sales indicates that higher loadings have been the chief driver of demand growth. Emission regulations are continuing to tighten globally for both passenger and commercial vehicles. 

Gasoline vs. diesel cars 

Today, there are higher loadings of palladium in gasoline autocatalysts and higher loadings of platinum in diesel autocatalysts. However, both autocatalysts carry some loadings of each metal. The catalytic efficiency of each metal is influenced by engine temperature, fuel type, all fuel quality and durability of the autocatalyst’s washcoat. Diesel engines operate at lower temperatures than gasoline engines and run with a leaner gas stream containing lots of oxygen. Under these conditions, platinum is a more active catalyst for the conversion of carbon monoxide (CO) and hydrocarbons (HC) to harmless emissions. However, the addition of some palladium to the platinum catalyst can improve its thermal stability. This is an advantage when reducing diesel particulate matter from the exhaust. This process involves trapping the particulate matter in a filter and then raising the temperature of the system to oxidise the matter to CO2. At these higher temperatures, palladium improves the thermal durability of the catalyst, helping it perform optimally for the lifetime of the vehicle. 

Diesel cars falling out of favour 

Europe is the largest diesel passenger car market in the world. In most of the rest of the world, gasoline cars dominate. However, even in Europe, diesel cars have fallen out of favour following ‘Dieselgate’ and tightening particulate emissions standards across Europe, where diesel cars do not perform as well as their gasoline equivalents (see figure 01 below).

Platinum versus palladium price 

In 2010, platinum used to trade close to 3 times the price of palladium. Dieselgate accelerated the trend of rising palladium relative to platinum prices. Today, platinum trades below half the price of palladium. Palladium’s growing demand and tightening supply have been a boon for prices (see figure 02 below).

Economical to substitute? 

With such a wide price differential between platinum and palladium, it’s a natural question to ask if platinum can be substituted for palladium? Industry experts including Johnson Matthey, believe there is some limited scope for substitution. Not necessarily in gasoline cars but more in terms of substituting out palladium in diesel cars with higher loadings of platinum. However, auto manufacturers are notoriously secretive about their technologies which makes it difficult to comment on what scale this will occur. In addition, it is rumoured that auto manufacturers are using their scarce engineers to develop electric vehicles and so auto manufacturers are averse to divert them to PGM substitution projects. 

Trucking industry 

While globally more passenger cars use gasoline than diesel, trucks generally use more diesel. Emission standards for trucks are tightening. Notably in India the government has tightened regulations to broadly match European standards in 20205. China will implement similar standards phased between 2021 and 2023. This is likely to be a strong catalyst for platinum demand. 

Car sales in COVID-19 era 

Passenger car sales had fallen hard during the COVID-19 pandemic, but as lockdown conditions ease, car sales appear to be rebounding strongly in China, Europe, and US (see figure 03 below). China and US are predominantly gasoline markets so the rebound in sales there mainly helps boost palladium prices. The rebound in European car sales should also help platinum prices.

The concentration in supply 

Supply in both platinum and palladium is highly concentrated. South Africa accounts for nearly 70% of platinum’s global supply while South Africa and Russia collectively provide around 70% of palladium supply globally. While platinum is expected to be in a slight supply surplus this year, palladium continues to be in an acute supply deficit with demand continuing to grow and supply relatively stable.  

Conclusions 

Both platinum and palladium are important materials for pollution abatement technology in cars. Platinum, which has been heavily utilised in diesel passenger cars, has fallen out of favour in recent years. However, with tightening regulations for commercial vehicles globally we are likely to see that demand rise. Palladium, which has seen growing demand and is in a supply deficit is likely to see constructive fundamentals for years to come.

This week, Brent Crude prices have strengthened by USD 1.2 per barrel since Monday’s opening. While macroeconomic concerns persist, market reactions have been subdued, with price fluctuations primarily driven by fundamental factors. Currently, the oil price stands at its weekly high of USD 84.4 per barrel, with Wednesday’s low recorded at USD 81.7 per barrel, indicating relatively normal price movements throughout the week.

The upward trajectory since Wednesday afternoon can be attributed to two main factors:

Firstly, Wednesday’s US inventory report, though mixed, conveyed a bullish sentiment to the market due to an overall decline in commercial inventories. The report from the US Department of Energy (DOE) revealed a draw in US crude inventories of 1.4 million barrels last week, surpassing consensus estimates of a 2.0-million-barrel draw –  the American Petroleum Institute’s (API) forecast of a 0.5-million-barrel build on Tuesday.

Additionally, a marginal improvement in refinery margins hints at healthier demand prospects leading up to the driving season. While commercial crude oil inventories (excluding Strategic Petroleum Reserve) decreased, standing approximately 3% below the five-year average for this period, total gasoline inventories saw a notable increase of 0.9 million barrels compared to the consensus forecast of a decrease of 1.1 million barrels. Distillate fuel inventories experienced a more moderate increase in line with expectations, rising by 0.6 million barrels but remaining approximately 7% below the five-year average. Overall, total inventories (crude + gasoline + distillate) showed a marginal increase of 0.1 million barrels, coupled with a 1% improvement in refinery utilization to 88.5% last week (see pages 11 and 18 attached).

The substantial draw in commercial crude inventories, particularly compared to the typical seasonal build, has emerged as a key price driver (see page 12 attached).

Secondly, the third consecutive day of oil price gains can be attributed to renewed optimism regarding US rate cuts, supported by positive US jobs data suggesting potential Federal Reserve rate cuts this year. This optimism has boosted risk assets and weakened the dollar, rendering commodities more appealing to buyers.

In a broader context, crude oil prices have been moderating since early last month amidst easing tensions in the Middle East. Attention is also focused on OPEC+, with Russia, a key member, exceeding production targets ahead of the cartel’s upcoming meeting. Expectations are widespread for an extension of output cuts during the next meeting.

Conversely, providing support to global crude prices is the Biden administration’s intention to increase the price ceiling for refilling US strategic petroleum reserves to as much as USD 79.99 per barrel.

With geopolitical tensions relatively subdued, but lingering, the market remains vigilant in analyzing data and fundamentals. Our outlook for oil prices at USD 85 per barrel for 2024 remains firm and attainable for the foreseeable future.

Brent rallied 2.5% last week on bullish inventories and bullish backdrop. Brent crude gained 2.5% last week with a close of the week of USD 89.5/b which also was the highest close of the week. The bullish drivers were: 1) Commercial crude and product stocks declined 3.8 m b versus a normal seasonal rise of 4.4 m b, 2) Solid gains in front-end Brent crude time-spreads indicating a tight crude market, and 3) A positive backdrop of a 2.7% gain in US S&P 500 index.

Brent falling back 1% on diesel concerns this morning. But positive backdrop may counter it later. This morning Brent crude is pulling back 0.9% to USD 88.7/b counter to the fact that the general backdrop is positive with a weaker USD, equity gains both in Asia and in European and US futures and not the least also positive gains in industrial metals with copper trading up 0.4% at USD 10 009/ton. This overall positive market backdrop clearly has the potential to reverse the initial bearish start of the week as we get a little further into the Monday trading session.

Diesel concerns at center stage. The bearish angle on oil this morning is weak diesel demand with diesel forward curves in front-end contango and predictions for lower refinery runs in response this down the road. I.e. that the current front-end strength in crude curves (elevated backwardation) reflecting a current tight crude market will dissipate in not too long due to likely lower refinery runs. 

But gasoline cracks have rallied. Diesel weakness is normal this time of year. Overall refining margin still strong. Lots of focus on weakness in diesel demand and cracks. But we need to remember that we saw the same weakness last spring in April and May before the diesel cracks rallied into the rest of the year. Diesel cracks are also very seasonal with natural winter-strength and likewise natural summer weakness. What matters for refineries is of course the overall refining margin reflecting demand for all products. Gasoline cracks have rallied to close to USD 24/b in ARA for the front-month contract. If we compute a proxy ARA refining margin consisting of 40% diesel, 40% gasoline and 20% bunkeroil we get a refining margin of USD 14/b which is way above the 2015-19 average of only USD 6.5/b. This does not take into account the now much higher costs to EU refineries of carbon prices and nat gas prices. So the picture is a little less rosy than what the USD 14/b may look like.

The Russia/Ukraine oil product shock has not yet fully dissipated. What stands out though is that the oil product shock from the Russian war on Ukraine has dissipated significantly, but it is still clearly there. Looking at below graphs on oil product cracks the Russian attack on Ukraine stands out like day and night in February 2022 and oil product markets have still not fully normalized.

Oil market gazing towards OPEC+ meeting in June. OPEC+ will adjust to get the price they want. Oil markets are increasingly gazing towards the OPEC+ meeting in June when the group will decide what to do with production in Q3-24. Our view is that the group will adjust production as needed to gain the oil price it wants which typically is USD 85/b or higher. This is probably also the general view in the market.

ARA diesel cracks saw the exact same pattern last year. Dipping low in April and May before rallying into the second half of the year. Diesel cracks have fallen back but are still clearly above normal levels both in spot and on the forward curve. I.e. the ”Russian diesel stress” hasn’t fully dissipated quite yet.

So far this week, Brent Crude prices have strengthened by USD 1.3 per barrel since Monday’s opening. While macroeconomic concerns persist, they have somewhat abated, resulting in muted price reactions. Fundamentals predominantly influence global oil price developments at present. This week, we’ve observed highs of USD 89 per barrel yesterday morning and lows of USD 85.7 per barrel on Monday morning. Currently, Brent Crude is trading at a stable USD 88.3 per barrel, maintaining this level for the past 24 hours.

Additionally, there has been no significant price reaction to Crude following yesterday’s US inventory report (see page 11 attached):

  • US commercial crude inventories (excluding SPR) decreased by 6.4 million barrels from the previous week, standing at 453.6 million barrels, roughly 3% below the five-year average for this time of year.
  • Total motor gasoline inventories decreased by 0.6 million barrels, approximately 4% below the five-year average.
  • Distillate (diesel) inventories increased by 1.6 million barrels but remain weak historically, about 7% below the five-year average.
  • Total commercial petroleum inventories (crude + products) decreased by 3.8 million barrels last week.

Regarding petroleum products, the overall build/withdrawal aligns with seasonal patterns, theoretically exerting limited effect on prices. However, the significant draw in commercial crude inventories counters the seasonality, surpassing market expectations and API figures released on Tuesday, indicating a draw of 3.2 million barrels (compared to Bloomberg consensus of +1.3 million). API numbers for products were more in line with the US DOE.

Against this backdrop, yesterday’s inventory report is bullish, theoretically exerting upward pressure on crude prices.

Yet, the current stability in prices may be attributed to reduced geopolitical risks, balanced against demand concerns. Markets are adopting a wait-and-see approach ahead of Q1 US GDP (today at 14:30) and the Fed’s preferred inflation measure, “core PCE prices” (tomorrow at 14:30). A stronger print could potentially dampen crude prices as market participants worry over the demand outlook.

Geopolitical “risk premiums” have decreased from last week, although concerns persist, highlighted by Ukraine’s strikes on two Russian oil depots in western Russia and Houthis’ claims of targeting shipping off the Yemeni coast yesterday.

With a relatively calmer geopolitical landscape, the market carefully evaluates data and fundamentals. While the supply picture appears clear, demand remains the predominant uncertainty that the market attempts to decode.
