Hi Loki, the Reuters article is saying that MF Global had legal authority to re-invest their clients funds under the umbrella of Re-hypothecation.
By contrast what was not said in the MF Global hearing this morning in Washington is that the MF clients will definately NOT be gett their money back, and neither will a whole lot of OTHER clients of those institutions who have RH'd.
I expect those institutions will experience a run untill the government bail out all the RH funds.
