From [0] we can see that there are 10 banks founded before 1700 and 24 from 1700 to 1800.

So it might not be that far fetched, assuming that the banks keep your accounts open after more than 100 years without use.

10 banks out of how many founded in 300 years?

I don't argue that it's probably a tiny fraction.

I was just pointing out that it might be somewhat possible for banks to exist for a span of time big enough for this.

As pointed out by other commenters: a non zero number have survived. A small investment made with many different institutions would substantially increase your chances of a massive return upon... return.

That's not the right question, though, because the expected rate of failure isn't constant throughout the lifetime of a bank. See, e.g., https://en.wikipedia.org/wiki/Lindy_effect

Seems like your best bet would be to park your money with several very old banks: https://en.wikipedia.org/wiki/List_of_oldest_banks_in_contin...

Also might want to think about purchasing bonds: https://en.wikipedia.org/wiki/List_of_oldest_banks_in_contin...

2nd link was supposed to be https://en.wikipedia.org/wiki/Perpetual_bond with information about a bond from 1648 with the issuer still paying annual interest.

Bitcoin! :)

What if they release Bitcoin 2.0 the year you leave?

Probably tiny?

Lloyds bank founded 1765

Barclays founded 1736

I doubt any banks in the new world are as old.

Berenberg Bank founded 1590 (429 years ago)

Monte dei Paschi di Siena 1472 (547 years ago)

So.... All western European then?
