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.

Brent crude prices have remained stable since the sharp price surge on Monday afternoon, when the price jumped from USD 71.5 per barrel to USD 73.5 per barrel – close to current levels (now trading at USD 73.45 per barrel). The initial price spike was triggered by short-term supply disruptions at Norway’s Johan Sverdrup field and Kazakhstan’s Tengiz field.

While the disruptions in Norway have been resolved and production at Tengiz is expected to return to full capacity by the weekend, elevated prices have persisted. The market’s focus has now shifted to heightened concerns about an escalation in the war in Ukraine. This geopolitical uncertainty continues to support safe-haven assets, including gold and government bonds. Consequently, safe-haven currencies such as the U.S. dollar, Japanese yen, and Swiss franc have also strengthened.

U.S. commercial crude oil inventories (excl. SPR) increased by 0.5 million barrels last week, according to U.S DOE. This build contrasts with expectations, as consensus had predicted no change (0.0 million barrels), and the API forecast projected a much larger increase of 4.8 million barrels. With last week’s build, crude oil inventories now stand at 430.3 million barrels, yet down 18 million barrels(!) compared to the same week last year and ish 4% below the five-year average for this time of year.

Gasoline inventories rose by 2.1 million barrels (still 4% below their five-year average), defying consensus expectations of a slight draw of 0.1 million barrels. Distillate (diesel) inventories, on the other hand, fell by 0.1 million barrels, aligning closely with expectations of no change (0.0 million barrels) but also remain 4% below their five-year average. In total, combined stocks of crude, gasoline, and distillates increased by 2.5 million barrels last week.

U.S. demand data showed mixed trends. Over the past four weeks, total petroleum products supplied averaged 20.7 million barrels per day, representing a 1.2% increase compared to the same period last year. Motor gasoline demand remained relatively stable at 8.9 million barrels per day, a 0.5% rise year-over-year. In contrast, distillate fuel demand continued to weaken, averaging 3.8 million barrels per day, down 6.4% from a year ago. Jet fuel demand also softened, falling 1.3% compared to the same four-week period in 2023.

Brent crude is maintaining its gains from Monday and ticking yet higher. Brent crude made a jump of 3.2% on Monday to USD 73.5/b and has managed to maintain the gain since then. Virtually no price change yesterday and opening this morning at USD 73.3/b.

Emerging positive signs from the Chinese economy may lift oil market sentiment. Chinese economic weakness in general and shockingly weak oil demand there has been pestering the oil price since its peak of USD 92.2/b in mid-April. Net Chinese crude and product imports has been negative since May as measured by 3mth y/y changes. This measure reached minus 10% in July and was still minus 3% in September. And on a year to Sep, y/y it is down 2%. Chinese oil demand growth has been a cornerstone of global oil demand over the past decades accounting for a growth of around half a million barrels per day per year or around 40% of yearly global oil demand growth. Electrification and gassification (LNG HDTrucking) of transportation is part of the reason, but that should only have weakened China’s oil demand growth and not turned it abruptly negative. Historically it has been running at around +3-4% pa.

With a sense of ’no end in sight’ for China’ ills and with a trade war rapidly approaching with Trump in charge next year, the oil bears have been in charge of the oil market. Oil prices have moved lower and lower since April. Refinery margins have also fallen sharply along with weaker oil products demand. The front-month gasoil crack to Brent peaked this year at USD 34.4/b (premium to Brent) in February and fell all the way to USD 14.4/b in mid October. Several dollar below its normal seasonal level. Now however it has recovered to a more normal, healthy seasonal level of USD 18.2/b. 

But Chinese stimulus measures are already working. The best immediate measure of that is the China surprise index which has rallied from -40 at the end of September to now +20. This is probably starting to filter in to the oil market sentiment.

The market has for quite some time now been staring down towards the USD 60/b. But this may now start to change with a bit more optimistic tones emerging from the Chinese economy.

The IEA could be too bearish by up to 0.8 mb/d. IEA’s calculations for Q3-24 are off by 0.8 mb/d. OECD inventories fell by 1.16 mb/d in Q3 according to the IEA’s latest OMR. But according to the IEA’s supply/demand balance the decline should only have been 0.38 mb/d. I.e. the supply/demand balance of IEA for Q3-24 was much less bullish than how the inventories actually developed by a full 0.8 mb/d. If we assume that the OECD inventory changes in Q3-24 is the ”proof of the pudding”, then IEA’s estimated supply/demand balance was off by a full 0.8 mb/d. That is a lot. It could have a significant consequence for 2025 where the IEA is estimating that call-on-OPEC will decline by 0.9 mb/d y/y according to its estimated supply/demand balance. But if the IEA is off by 0.8 mb/d in Q3-24, it could be equally off by 0.8 mb/d for 2025 as a whole as well. Leading to a change in the call-on-OPEC of only 0.1 mb/d y/y instead. Story by Bloomberg: {NSN SMXSUYT1UM0W <GO>}. And looking at US oil inventories they have consistently fallen significantly more than normal since June this year. See below.

Later today at 16:30 CET we’ll have the US oil inventory data. Bearish indic by API, but could be a bullish surprise yet again. Last night the US API indicated that US crude stocks rose by 4.8 mb, gasoline stocks fell by 2.5 mb and distillates fell by 0.7 mb. In total a gain of 1.6 mb. Total US crude and product stocks normally decline by 3.7 mb for week 46.

The trend since June has been that US oil inventories have been falling significantly versus normal seasonal trends. US oil inventories stood 16 mb above the seasonal 2015-19 average on 21 June. In week 45 they ended 34 mb below their 2015-19 seasonal average. Recent news is that US Gulf refineries are running close to max in order to satisfy Lat Am demand for oil products.

Since market opening on Monday, November 18, Brent crude prices have climbed steadily. Starting the week at approximately USD 70.7 per barrel, prices rose to USD 71.5 per barrel by noon yesterday. However, in the afternoon, Brent crude surged by nearly USD 2 per barrel, reaching USD 73.5 per barrel, which is close to where we are currently trading.

This sharp price increase has been driven by supply disruptions at two major oil fields: Norway’s Johan Sverdrup and Kazakhstan’s Tengiz. The Brent benchmark is now continuing to trade above USD 73 per barrel as the market reacts to heightened concerns about short-term supply tightness.

Norway’s Johan Sverdrup field, Europe’s largest and one of the top 10 globally in terms of estimated recoverable reserves, temporarily halted production on Monday afternoon due to an onshore power outage. According to Equinor, the issue was quickly identified but resulted in a complete shutdown of the field. Restoration efforts are underway. With a production capacity of 755,000 barrels per day, Sverdrup accounts for approximately 36% of Norway’s total oil output, making it a critical player in the country’s production. The unexpected outage has significantly supported Brent prices as the market evaluates its impact on overall supply.

Adding to the bullish momentum, supply constraints at Kazakhstan’s Tengiz field have further intensified concerns. Tengiz, with a production capacity of around 700,000 barrels per day, has seen output cut by approximately 30% this month due to ongoing repairs, exceeding earlier estimates of a 20% reduction. Repairs are expected to conclude by November 23, but in the meantime, supply tightness persists, amplifying market vol.

On a broader scale, a pullback in the U.S. dollar yesterday (down 0.15%) provided additional tailwinds for crude prices, making oil more attractive to international buyers. However, over the past few weeks, Brent crude has alternated between gains and losses as market participants juggle multiple factors, including U.S. monetary policy, concerns over Chinese demand, and the evolving supply strategy of OPEC+.

The latter remains a critical factor, as unused production capacity within OPEC continues to exert downward pressure on prices. An acceleration in the global economy will be crucial to improving demand fundamentals.

Despite these short-term fluctuations, we see encouraging signs of a recovering global economy and remain moderately bullish. We are holding to our price forecast of USD 75 per barrel in 2025, followed by USD 87.5 in 2026.
