As the world held its breath, in November 2016, for President Trump's election, we noted that equity market implied correlation is flashing a 'panic' warning according to BMO quant Mark Steele as the little-known derivative indicator suggests traders fear a major 'high correlation' event and are aggressively hedging systemic risk.
And now, amid the massive unwind of the Short-Vol trade, implied correlation - the other fear index - is flashing red, as Bloomberg notes, the wild market fluctuations of recent days are sending bets for equity correlations to levels not seen since before the election (and Brexit).
