Global catastrophic financial risks?

Have there been any good analyses of possible global catastrophic financial risks?

I’m thinking of issues such as:

1) narrow AI traders cornering global capital markets through more efficient predictions, trades, and arbitrage, so ordinary folks are left with near-zero equity and pensions

2) blockchain and cryptocurrency technologies disrupting fiat-currency-denominated investments enough that most folks lose their net worth

3) AIs plus human traders finding leveragable vulnerabilities in insurance markets and engineering medium-sized physical catastrophes that turn into global financial catastrophies

4) sudden regulatory or tax-policy changes that have unanticipated snowballing effects, e.g. eliminating the US mortgage interest tax deduction suddenly crashing the US housing market.

I’d appreciate any pointers to analyses of situations like this from an EA perspective. Cheers—G
