Automobile production drops due to COVID-19, therefore the price of palladium drops. As its used in catalytic converters. But as the productions resumes we might see a price raise of palladium. Plus as the laws get stricter about the pollution the price of palladium will rise, until there is a cheaper/better alternative, or production switches to electric cars.
