As has been generally observed, banks aspire to 'total finance' a term based on the 'total football' strategy made famous by the World Cup-losing 1970s Dutch national soccer team.
Unfortunately, 'total finance', which I coined (trademark pending), is not yet an approved standard expression of bank marketing departments. Instead, banks have historically used such unwieldy taglines such as 'allfinanz', 'bancassurance' or the dreaded, but generic, 'one-stop-shop' to describe the concept of delivering consumers all their financial services via a single institution.
(BNZ's 'Total Money', while it sounds similar, has a totally different meaning.)
In theory, the goal of total finance makes sense but, as an Ernst & Young global banking survey showed this year, consumers like to dally with numerous financial partners.
Banks, too, often struggle to make the constituent components of the total finance machine operate smoothly. At the very least banks are always tinkering with the parts, particularly so when it comes to funds management.
