I think one first step is to dis­tin­guish between tra­di­tion­al bank­ing, which sells mon­ey it has (or it can bor­row very quick­ly, what­ev­er) and finance, which sells some­thing it does not have. And in that sell­ing what it does not have lies its cre­ativ­i­ty. It has to invent instru­ments. And secondly—and they go together—it has to invade oth­er sec­tors. Because it itself does not have what it needs to pro­duce.
