Way before that, actually. At the very least, since GFC of 2008. Traditional valuation models died long ago. My vague belief is that the only deciding factor for markets now is the amount of capital free for investing (and that multiplied massively through QE and covid handouts). So we have trillions of dollars sloshing around looking for a home. Be loud as Musk and it will flow your way, regardless of what you are actually producing. Hence the unhinged valuations of several top companies.







Just talk to your bank, you are not alone in this situation! If the deposit is sizeable enough, they will transfer your account to their international operation. If not - why do you even care? Just take it out as cash, or wire it to a bank in your new place.
On the retirement savings - there is also a mechanism of transferring it to your new country of residence.
