For decades, deposit management in financial institutions has largely been treated as an operational responsibility. Retail teams focused on product features, deposit growth, and competitive rates, while success was typically measured by balances, cost of funds, or deposit betas. Those metrics still serve a purpose, but they miss something far more important.
Deposits are not simply a funding source. In many institutions they represent the most valuable strategic asset on the balance sheet, influencing liquidity stability, lending capacity, interest rate risk, and ultimately profitability. Yet despite this reality, the economic value of deposits is rarely measured in a way that reflects their true contribution to the institution.
Changing the Narrative
Retail deposit leaders who want to raise their profile inside their organizations have an opportunity to change that narrative. When deposits are analyzed correctly, their contribution to enterprise value becomes clear, and the role of deposit leadership naturally shifts from operational management to strategic balance sheet oversight.
At the most basic level, deposits are the engine that powers balance sheet economics. Every financial institution must fund its assets, and loans and investments require capital that comes either from deposits or from wholesale borrowing. When deposits replace wholesale funding sources such as Federal Home Loan Bank advances or brokered deposits, they generate an immediate economic benefit.
If deposits cost less than alternative funding sources, the difference directly improves the institution’s net interest margin. However, the value of deposits extends beyond funding cost alone. Deposits influence liquidity stability, determine how much lending the institution can support, and shape the organization’s interest rate risk profile. A strong deposit franchise allows institutions to grow assets without becoming dependent on volatile market funding. In this sense, deposits are not merely liabilities; they form the foundation of the balance sheet.
Using the Wrong Metrics
Despite their importance, deposits are still often evaluated using metrics that obscure their economic contribution. Deposit growth, average cost of funds, and deposit beta analysis can provide operational insight, but they fail to answer a more important strategic question: how much economic value do deposits actually create for the institution? Two deposit products may carry similar rates but deliver very different levels of value once operating costs, funding alternatives, and balance sheet implications are considered. Without a framework that captures these relationships, deposit leaders risk being perceived primarily as product managers rather than as contributors to enterprise strategy.
The Role of Funds Transfer Pricing
Understanding the real value of deposits requires evaluating them relative to the institution’s marginal cost of funding. This is where Funds Transfer Pricing, or FTP, becomes essential. FTP assigns an internal funding value to deposits based on the cost of raising funds in external markets. By transferring deposit balances internally to lending or investment units at this funding rate, the institution can measure how deposits contribute to profitability across business lines.
For term deposits such as certificates of deposit (NMDs), assigning FTP rates is straightforward because the maturity is known. Non-maturity deposits, checking, savings, and money market accounts, present a greater challenge because they have no contractual maturity and can be repriced at any time.
Rather than relying on complex behavioral maturity assumptions, many institutions have adopted a spread-based approach for assigning FTP rates to non-maturity deposits. Under this approach, the institution begins by identifying its marginal cost of wholesale funding, often represented by sources such as Federal Home Loan Bank advances or other borrowing alternatives. The value of deposits is then determined by the spread between this market funding rate and the rate paid on deposits.
This spread represents the economic benefit created when deposits replace external borrowing. Importantly, the spread is not assigned arbitrarily. It is derived from historical analysis of how deposit rates behave relative to market funding costs. By examining how deposit pricing has historically moved compared with wholesale borrowing rates, institutions can estimate the typical relationship between deposit rates and market funding benchmarks. This empirical relationship provides a defensible basis for the FTP spread applied to deposits.
Impact on Interest Rate Risk
Determining this spread does more than quantify the value of the deposit franchise. It also reveals an important source of balance sheet risk: basis risk. Deposit rates respond to factors such as customer behavior, competitive pricing pressures, and changes in short-term interest rates. Wholesale funding costs, however, may move with different benchmarks such as SOFR, swap curves, or FHLB advance rates. When these benchmarks move differently, the relationship between deposit rates and marginal funding costs changes. That divergence represents basis risk in the institution’s funding structure. Recognizing this distinction allows institutions to separate interest rate risk, which reflects changes in the overall level of rates, from basis risk, which reflects changes in the relationship between deposit pricing and wholesale funding markets.
The spread approach also has important implications for interest rate risk management. Non-maturity deposits can legally be repriced at any time, meaning they do not carry the same contractual duration as fixed-rate loans or securities. When deposit pricing is managed relative to a market benchmark and the spread relationship is maintained, institutions can adjust deposit rates as market conditions change while preserving the economic relationship between deposits and wholesale funding costs.
In practice, this means the institution focuses on managing the spread between deposit rates and market funding costs rather than attempting to estimate behavioral maturities decades into the future. By maintaining this spread relationship, much of the interest rate risk associated with deposit funding can be mitigated.
Where’s the Value
Once deposits are analyzed within this framework, another insight often emerges, one that frequently surprises senior executives. Deposits can create more economic value than lending operations themselves. This observation challenges one of the most deeply embedded assumptions in banking, which holds that lending is the institution’s primary profit engine.
Consumer lending in particular often involves significant credit losses, marketing expenses, servicing costs, regulatory compliance costs, and capital requirements. When these costs are fully incorporated into profitability analysis, the net economic contribution of many consumer lending portfolios can be far smaller than commonly assumed. By contrast, the deposit franchise generates economic value simply by providing stable, low-cost funding.
When deposits are transferred internally at market funding rates, the spread between deposit costs and wholesale borrowing costs often represents a significant portion of institutional earnings. In some cases, institutions can demonstrate that replacing portions of their consumer lending portfolios with investment assets funded by deposits would produce higher risk-adjusted profitability.
This does not diminish the importance of lending relationships, which often serve as a key driver of customer engagement and deposit acquisition. However, it highlights a reality that is frequently overlooked: the deposit franchise itself may be the most valuable component of the financial institution.
The Chief Deposit Officer
As institutions increasingly recognize this reality, governance structures are beginning to evolve. Some organizations have introduced the role of Chief Deposit Officer to coordinate deposit strategy across retail banking, treasury, marketing, and asset-liability management. This development reflects a broader shift in thinking. Deposits are no longer viewed simply as retail products but as the primary funding mechanism that supports lending, liquidity management, and interest rate risk strategy.
Retail deposit leaders who can quantify the funding value of deposits, understand the spread between deposit rates and wholesale borrowing costs, and identify emerging basis risk begin speaking the same language as treasury, ALCO, and the CFO. When deposit leaders frame their decisions in terms of balance sheet economics rather than product management, their role naturally expands.
Summary
At that point, deposit leadership is no longer defined by rate sheets and promotional campaigns. It becomes defined by stewardship of one of the most important economic relationships on the balance sheet: the spread between deposit funding and market borrowing costs. And managing that relationship effectively is precisely the kind of responsibility that elevates deposit leadership to the strategic level.

Kohl Analytics Group helps banks and credit unions understand the true economics of their business through deep profitability and operational analysis. The firm measures profitability at the individual loan and deposit level and across products, customers, channels, and branches.
Kohl's approach is built on Time-Driven Activity-Based Costing (TDABC), which measures the time employees spend performing operational activities such as underwriting, account opening, servicing, and compliance. Because employee effort drives most non-interest expense, this produces a far more accurate view of costs and profitability.
Kohl also maintains a large activity benchmarking database, enabling institutions to perform capacity analysis, identify inefficiencies, and uncover operational improvement opportunities.
