Yesterday, Reuters royally spooked the market when it announced that Europe is in all seriousness considering full blown capital controls, including border halts and ATM closures. Subsequently, various European talking heads aggressively tried to talk down this latest development. However, overnight Saxo Bank appears to have focused on the former and not the latter, and sent out an email with the following key text: "Due to the current market environment in Europe, Saxo Bank is adjusting the margin requirement for Swiss Franc (CHF)." Specifically, the margin is going from 1% to 2% on June 14, to 4% on June 21. How soon until margins become so high that they effectively act as an FX trading prohibition- i.e., an implicit "capital control", and how long until all other exchanges get the memo next?
