Yep, nobody will want bonds at future yields, except for governments in reciprocal agreements, a circle-jerk.
Virus effects in the US will get worse before they get better, same in europe. People freak out when they are quarantined. I think there will be strongly suggested voluntary large-scale quarantines here, but a quarantine has to be almost complete in order to have a good effect.
Yes spreading the cases out over time is essential, given the lack of beds—but in the meantime the news gets reported, and the algos react.
Really tough to say what will happen one way or another. The best you can say is that in 2 years’ time it will have mostly run its course, maybe with secondary flare-up, and will have killed a bunch of old and weak, and maybe left a bunch of otherwise healthy people injured.
And that last point is IMO the important one: what is the morbidity, especially in working-age individuals? And what is it with successive infections, as that is reported to be possible? A vaccine is key to avoiding the morbidity effects resonating into the future and affecting economies.
