I think a lot depends on whether the US keeps being an unreliable actor and thus a pain to deal with.

If there's enough pain, it'll outweigh the pain of switching.

If you are using the dollar right now, what pain are you taking? None. What's actually happened? US added some tariffs and became a bit more isolationist and the Fed has lost some independence. Might not bode well for the future but has very little impact on today.

Even if the dollar was "dead" the time and effort required by the world economy to switch away from the dollar system would be enormous so not much is likely to happen quicker than a few decades.

This warrant's a little caution, there may well be some negative selection bias here. The banks most likely to go bust are the ones most desperate for cash so they offer the highest interest rates... If it's FDIC insured you are good up to $250k but I don't know exactly how much inconvenience is associated with your bank going bust and potentially collecting FDIC insurance.
dia80 commented on Is it insider trading if I bought Boeing puts while inside the wrecked airplane?   law.stackexchange.com/que... · Posted by u/wazbug

UK rules differ from the US there is a 3-point test for insider trading:

1. The information has to be specific - Yes - you should sell Boeing

2. Would a reasonable investor take this information into account when making a decision to trade - Yes - this seems quite clear

3. The information must be non public - IIRC disclosure to a large group of people - in this case the perhaps 200ish people on the plane knowing it had a problem would probably count as the information being public and thus this test is not met and you are free to trade - I think the bar is around 30 people

I knew all those hours spent in compliance training would come in handy one day!

> having information about the future

How, uh, do you do this legally?

>If you are using python

And if you're using C++?

Forecast! Time to reach for your linear regression, GBDT or NN.

Quant trader here... I'm a big seller of this list. Making money tends to be a relatively empirical endeavor. It's all about having information about the future and using that in judiciously way and less so about any particular theory or model. I see someone else mentioning Grinold and Khan "Active Portfolio Management", I can't recommend it enough, it's basically a how to for making money quantitatively in a principled way, there are lots of "tips and tricks" that go on top of this and it really helps to have some good intuition for the space you are trying to operate in (by that I mean understanding the eigenvalues and eigenvectors of your risk matrix). T-costs are also extremely important and the main "enemy" it's trivial to make money if you don't have to pay to trade.

Steven Boyd at Stanford and his students / colleagues are probably the richest seam of up to date portfolio optimization wisdom. If you are using python you shoult probably be using CVXPY to build your portfolio. He has lots of good papers, e.g. see [2].

Of course you also need an "edge", that information about the future, and that's the jealously guarded part...

Those that have any doubts about the necessity of this initiative should take the time to watch the Center for Humane Technology's "The AI Dilemma" from March 9th.

Why are we complaining about the VCs when this isn’t their fault? If you want people to blame, it’s Newt Gingrich and Bill Clinton for repealing the Glass Steagall Act. The exuberance and recklessness of the 90s is now haunting us, just like with Reagan’s deficit spending. This not being mentioned in over a dozen articles points to the failure of the mainstream media yet again, and they wonder why no one trusts them anymore.

Dodd Frank obviously is not good enough. If I were to guess, it was drastically weakened by lobbyists.

As I understand it SVB is insolvent primarily due to incompetence, the actual actions they have taken: take deposits and buying US treasury bonds are every day activities for a bank. There are no exotic derivatives or off balance sheet special purpose vehicles. It's hard to regulate that away.
