OTC precious metals trading slowed for a third consecutive week, with the spot and the swaps/forwards markets retracting across all four metals. The age old adage of ‘sell in May and go away’ may be proving true for the gold market at least, where since the end of May (Weekly LBMA Trade Data, week ending May 30) the weekly spot market has only traded in excess of 100million oz once (that occurred during week ending June 28).
