Do Funds in the Vault count toward family funds when calculating interest for the Shrewd trait?

SO what's even the point in Money Vaults then?

Apart from aesthetics, they allow you to go over the maximum cash limit (though I'm not sure why anyone would need to), they offer some gameplay interactions, and they can be used to split funds when you're separating households (ie. the son of a family wants to get married and move out, he can put money in the vault before he moves and come back to collect it later after he moves out)
