You're right. This should be added to the Rules and Policies wiki page. There *is* a warning for characters who attempt the trade, I believe.
EDIT: I see the warning isn't particularly clear as to *why*. Fixed.
SECOND EDIT: I found the rule that Anaris and I probably remember, but it was never listed with 'rules', but upon frequently rejected wikilist.
Transfers of Gold (not bonds); Transfers of Money Not in Cities
These would seriously upset the balance of the game, allowing long-distance wars and a number of other things Tom does not want. There's a reason for the difference between gold and bonds.
Added to Rules and Policies page.
