Ukraine repercussions place 2.6mn vehicles at risk in 2022: S&P Global Mobility

With conflict in Ukraine comes more reminders of the fragility of the world's automotive supply chains. The March light vehicle production update from S&P Global Mobility (formerly the automotive team at IHS Markit) is likely to downgrade its 2022 forecast by 2.6mn units (i.e. to 81.6 million). The downgrade decomposition will broadly comprise just under 1mn units from lost demand in Russia and Ukraine; and the remainder split between 1) worsening semiconductor supply issues, and 2) loss of Ukraine-sourced wiring harnesses and other components respectively. In addition, the complete loss of Russian palladium is a tail risk with the potential to become the industry's biggest supply constraint.

Pent-up demand reduced by roughly one third

Pre-Ukraine invasion on 24th Feb, the global auto industry had already spent over a year under capacity constrained conditions, with (we estimate) pent up consumer demand up to 10mn units (or 12%) above this year's achievable production. The sudden loss of economic confidence (via high oil and raw material prices, weak equity markets, and tightening interest rates) is dampening demand, and could now reduce that shortfall by roughly one third - though significant pent-up demand remains.

Supply chain remains the constraining factor

While the macro concerns are significant, the supply chain (and not underlying consumer demand) will continue to set the upper limit for vehicle unit sales in the medium term. The key crunch points weighing on production levels post invasion fall into two broad categories: Semiconductor materials supply (specifically via Ukrainian neon and Russian palladium), and electrical wiring harness sourcing.

Specialist material outages could curtail semiconductor recovery

Semiconductor supply challenges are worsening on two fronts: First, via neon gas supply disruptions. Ukraine's firms control around half of high purity neon supply to the semiconductor industry, where the element is used in lasers that etch patterns onto chips. Our channel checks suggest immediate risks are low thanks to semiconductor makers holding sufficient gas inventory, but visibility is poor. The second challenge is availability of palladium, used in semiconductor plating and finishing. In an additional negative twist, China COVID-19 cases at a 2 year high are triggering quarantines and plant closures in northeastern manufacturing hubs including Shenzhen and Changchun. All of the above raise the risk of losses from 'stranded' chips, i.e. semiconductors for which the 'right' car cannot be built due to other constraints.

Ukraine wiring harnesses difficult to substitute

Our channel checks suggest Ukraine-built wiring harnesses were likely destined for around 0.5 to 1mn vehicles pre-invasion. These harnesses comprise complex and manually constructed assemblages of cable. Although some dual sourcing arrangements exist, for the most part switching will be difficult due to already-constrained harness capacity in and around Europe. Production relocations could take 3-10 months due to wait times on machinery and multi-month staff training times. Almost half (45%) of Ukraine-built wiring harnesses are normally exported to Germany and Poland, placing German carmakers at high exposure. Our analysis suggest Opel (i.e. Stellantis via Leoni), VW (via Leoni and Sumitomo) are over-exposed versus peers. On the plus side, once ramped up - lost production could be recovered quickly into late 2022 and beyond.

Palladium: Next 'black swan' candidate

While low probability as things stand, palladium has the potential to become the industry's biggest supply constraint. Russia produces 40% of the world's mined palladium according to USGS. Around two thirds of palladium use is in vehicles, where it is the active element in catalytic converters for exhaust aftertreatment. If Russian palladium supply were suddenly interrupted (due to a western boycott, or Russia stopping supply), production of all vehicles using such sourcing (including hybrids) could potentially stop. Although platinum is an alternative element, it is similarly expensive and also largely Russia-originated. Substitution of any kind is a regulatory minefield since design changes require regulatory re-homologation, which can take months. We do not currently incorporate major palladium disruptions in our forecast base case.

Duraludon Joins Pokemon Unite Roster On March 14

After being teased during the recent Pokemon Presents livestream--the same presentation as the Pokemon Scarlet and Violet reveal--the Steel- and Dragon-type Pokemon Duraludon will be coming to Pokemon Unite on March 14.

A brief Character Spotlight trailer was released showing off Duraludon's abilities, which, thanks to its Ranged Attacker designation rely heavily on long-distance battles using lasers and other projectiles. It can also create floating rocks that damage enemies over time, release a burst of energy for area-of-effect damage, and emit a shockwave that sends it backwards, creating distance between it and nearby opponents.

Duraludon's Unite move was also revealed in the trailer, an orange laser blast followed by a massive area-of-effect attack that covers nearly the entire center area of the map. This new entrant into the Pokemon Unite arena looks to be effective against both opposing team members and wild Pokemon, but we won't know for sure until March 14.

Pokemon Unite is a free-to-play five-on-five MOBA set in the Pokemon universe, with teams gathering energy from battling Pokemon in order to score points. Other recent Pokemon additions include the Legendary Pokemon Hoopa, the sentient sword and shield Aegislash, and the ghost tree Trevenant.
