These are good points. There are number of "global systemic risk" institutes around the world, and many of them do focus on financial risk. But I would guess they would be concerned more with two and four, and not have one or three on their radar. I'm not aware of any EAs working on this.

Hauke thinks this might be worthy of further investigation:

Macroeconomic stability: A recent Lancet study suggests that the 2008 financial crisis was was associated with about 500,000 excess cancer-related deaths worldwide. This is just cancer, which only contributes to about 15% of global mortality and so a naive extrapolation might suggest mortality figures in the millions. Other factors such trade and tourism suffered significantly due to the economic crisis and thus poor countries were probably hit harder in terms of wellbeing. Fund Riccardo Rebonato, an expert on stress testing, to write more on banking regulation and stress testing banks.
