It doesn't get much more obvious than this. The S&P at multi year highs, and what does the CME do? Why it lowers initial (as in please come in and open new positions) spec margin for not only the E-Mini, but virtually every other major market "reflexive" product in existence including S&P, Dow Jones, Nasdaq, and subsector futures currently traded, by 12%. As a reminder, the last time that "other" asset class rose to multi-year highs, that would be gold, it hiked margin nearly every single day, with a culmination of two margins hikes in one day on May 4 [3]. Naturally, the margin hiker-in-chief [4]is not as worried about stocks attaining the same bubble status since if anything it will merely cement reelection chances. That said, should WTI ever dare to go up above $100 watch as the CME proceeds to decimate anyone who dares to be long WTI futures on margin.
