Platinum prices have started out Tuesday's session under pressure and in close proximity to Monday's low. Platinum was unable to find any notable support from news of potential production problems at a South African platinum mine that was the result of labor issues. For the time being, many traders feel that the platinum market may be taking the majority of its direction from the ebb and flow of demand concerns. As in many physical commodity markets, there may not be a lot of confidence that the world's central banks are going to act quickly, and that has left fears of sluggish global growth as a dominant market theme.
