PLATINUM dealers and analysts greeted warily Wednesday’s news that Russia has moved closer to unblocking platinum exports, but said the price will tumble in the medium term as metal comes onto the market. Spot platinum dipped $3 from its New York close to $437/$442 on the release of the news, but quickly recovered to $441.50/$446.50. A bill passed at the third and final reading in Russia’s State Duma lower house of parliament on Wednesday amends a law of December 1998 which effectively stopped exports as loose wording had made it impossible to identify an agent authorised to carry out exports.
