WHY WOULD Palladium go down?
I can't tell you with any certainties why it's coming down but I can think of a few potential factors like:
~ Lower demand for Palladium as an investor point of view
~ There is an increase in the supply of palladium - I assume with all of the automotive catalysts and with the higher confidence in electric vehicles (cough Tesla)
~ Interest rate changes with there talks about inflationary measures and interest rate drops, this can result in a drop in Palladium prices
~ Technological advancements reducing the need for palladium. For example, they may be using alternatives like Rhodium, Iron, PLatinum for catalysts in newer vehicles that contain less palladium.
