Moments ago, US equity futures tumbled to their lowest level in the overnight session, down 22 points or 1.1% to 1924, following both Europe (Eurostoxx 600 -1.8%, giving up more than half of yesterday’s gains, led by the banking sector) and Japan (Nikkei -2.2%), and pretty much across the board as DM bonds are bid, EM assets are all weaker, oil and commodities are lower in what is shaping up to be another EM driven “risk off” day. Only this time one can’t blame the usual scapegoat China whose market is shut for the long weekend.
