Central banks are going to have to intervene in the credit (corporate bond) market
As was seen again in 2018, credit spreads can widen drastically when risk aversion rises and liquidity can dry up drastically also in the credit (corporate bond) market. This is highly disruptive both for the financing of the economy and for institutional investors. Since banks can no longer provide liquidity in the corporate bond market, it would be very helpful if central banks intervened in this market (like the ECB did during quantitative easing) to get credit spreads back to normal.
