If you do it in a country that doesn't allow you to be declared legally dead when you are out of contact for a couple centuries, and if the institutions involved don't collapse, and if the interest on the account outpaces inflation, sure.
What percentage of the banks that were around 222 years ago have not failed?
So it might not be that far fetched, assuming that the banks keep your accounts open after more than 100 years without use.

Lloyds bank founded 1765
Barclays founded 1736
I doubt any banks in the new world are as old.
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...
