(New York)

JP Morgan is telling investors to get ready for a “new normal” of volatility. The bank’s CEO, Jamie Dimon is warning investors that global headwinds and liquidity constraints because of tighter regulations will mean there are bigger price swings in markets from now on. Dimon cited the Fed’s policy change, Germany’s slowdown, Brexit, and the US-China trade war.

FINSUM: We are so tired of this argument that tighter bank regulation hurts liquidity and leads to bigger market swings. Bank-provided liquidity is the great myth of the post-Dodd-Frank era. When markets get tough, bank trading desks often step away from the market, meaning liquidity vanishes just when you need it most.
