One of the challenges facing banks seeking to gain “share of wallet” among the very wealthiest households is the need to offer products and services catering to this group. The chart indicates, for ownership of financial assets, the sharp contrast between the “super-rich” (i.e. the wealthiest ½ % of households) and the “mass market” (i.e. the least wealthy 90% of households). The “mass market” have their financial assets concentrated among assets that fall within the realm of traditional banking: real estate, deposits and small business. As shown in the chart, about 60% of the assets of the “mass market” ($9.8Tn) are held in such "banking type” assets. Whilst the ratio of “banking” to “investment” assets is about 60-40 for the “mass market”, the reverse is true for the wealthiest ½ % of households. Gaining “share of wallet” among the “super-rich” will require banks to offer compelling services related to their asset holdings.
