Do you actually believe that there is some set of bank vaults out there in random islands and offshore principalities that are stuffed full of $32tn in cash and gold? No, the money leaves those offshore locations just as soon as it arrives and returns to places like the US and Europe to be invested in conventional assets that can appreciate in value or return dividends. The money is only secured by the willingness of the offshore entities to hide its ownership, it is not actually in those countries.
