Capital requirements for banks based on how much “distressed debts” hedge funds raise money?

Sir, Joe Rennison’s and Lindsay Fortado’s “Distressed debt tempts investors in anticipation of the next downturn”, June 19, raises the following question:

Could an index that tracks how “US hedge funds specialising in distressed debt are raising money in anticipation [of] the next economic downturn” be useful to base bank capital requirements on? 

At least it should be much better than current regulations, which allow banks to build up dangerous exposures to what is perceived as safe, against especially low capital requirements, especially when a Jason Mudrick, founder of $1.9bn Mudrick Capital can state “This economy is roaring right now”
