So that alarmist rag ZH breaks this story, all the comments insinuate this is some contrived margin call to squeeze long metals positions.
Now they flip-flop and imply the change will cause a gross expansion of risk as if speculators will suddenly open positions Monday with the windfall expansion of leverage the disparity between initial/maint offers them.
In their infinite stupidity ZH fails to mention with the exception of a few products "evil" exchange members never have to post initial margin to begin with (only maintenance). So IMO this is just a protection being offered to retail accounts facing liquidation through no fault of their own because of MF transfers.
I can't believe anyone reads this shit. This is a nonevent and just a small temporary added protection for the little guy, kudos to CME.
