Why? Because 1) PBs are emerging as a major player and lender in crypto markets and2) The current lending standards of PBs are tight, largely lending to low drawdown strategies (like delta-neutral), and presents low systemic risk. But, 3), if expected returns of delta-neutral strategies decline, then PBs may move out the risk curve in terms of who they are willing to lend to and what services they offer, which could brew systemic risk.
