Consumer Deposits – Optimizing Decision Spaces

Financial Institutions and Customers are solving different optimization problems.

Financial Institutions traditionally manage deposit portfolios through product categories, balances, rates, and campaigns. This approach is operationally familiar, but it does not fully reflect how Customers make decisions.

Customers do not merely hold products. They move money through Decision Spaces. They accept, reject, renew, switch, park, wait, re-enter, and leave. Their observed behavior reveals where decision Boundaries exist, where thresholds are crossed, and where the Financial Institution has practical opportunities to influence outcomes.

This paper proposes a framework, operating model and path to optimization of Customer Decision Management for Consumer deposits. The central idea is simple:

Customers optimize their own decision problem.  They progressively expand the array of actionable options until they find an acceptable solution, or the cost of acquiring more options is unacceptable.

This is not just theory. Every behavior described in this paper is observable in data. The facts exist in your own data. We have simply organized them into a coherent framework.

This is practical. We have included steps that can be taken with little to no investment to help you prove applicability in any Financial Institution and generate value immediately.

The set of actionable options available to Customers defines what we call a Decision Space. Decision Space Boundaries must be crossed to add more options. Different Decision Spaces create different response functions, and different response functions create different distributions of funds across products, terms, and destinations.

Those distributions reshape the portfolio’s term structure, growth, attrition and the Financial Institution’s cost of funds, liquidity, and profitability.

The value lies in precision and control. Eight separate Decision Spaces and Boundary transitions enable strategic and tactical actions to be operationally targeted and optimized.

A Financial Institution can improve portfolio management by understanding Decision Spaces, identifying the Boundaries that Customers cross, and aligning price options, feature options, and product-array design to those Boundaries.

The goal is not merely better pricing. The goal is better deposit portfolio management.
