No real sanctions have been imposed on Russia regarding platinum, palladium, and rhodium, for example. South Africa is the largest producer of platinum, and the industry has been facing significant issues due to factors like the lagging platinum price and rising costs. Platinum has also started to replace palladium in hybrids, for instance, which still use catalytic converters.

The platinum price has been stuck between approximately $800–$1100 for several years and has offered several short-term long and short trades. After a significant drop over the last five days, platinum has fallen to near the $930–$945 support level.

Platinum oversupply has plummeted from previous years; although there is still a surplus this year, it is considerably smaller. However, this drop has not yet been reflected in the platinum price, and the gap compared to gold, for instance, remains at a historically high level. Larger players have been particularly cautious with their platinum investments, which has maintained a fairly steady trading range where the price has hardly fallen below $900, and larger upside attempts have been quickly sold off.
