Unit 7 Bank Balance Sheet Analysis

The bank and every figure are composite; the rule, regulation and article cited are real. Risk weights are simplified to the main categories.

The Bank and Its Choice of Framework

The bank has $1.2 billion of assets and $114 million of tier 1 capital, almost all common equity. Since 2020 it has used the simplified community bank capital framework, known by its initials as the CBLR. A bank with less than $10 billion of assets, limited off-balance-sheet exposures and little trading activity may elect it, and if its tier 1 capital is more than 9 percent of average total assets, it is deemed well capitalized without calculating risk-based ratios at all (Regulatory Capital Rule: Capital Simplification for Qualifying Community Banking Organizations, 84 Fed. Reg. 61776, 2019). The framework saves reporting work, but it treats a Treasury bill and a commercial loan the same way: each dollar of assets needs nine cents of capital.

The Balance Sheet, Sorted by Risk

Under the standard risk-based rules, assets carry weights that reflect their credit risk (Capital Adequacy of FDIC-Supervised Institutions, 12 C.F.R. pt. 324, 2024). Sorting the bank's balance sheet into the main groups gives the following.

Zero percent weight. Cash and reserves, $60 million; U.S. Treasury securities, $90 million. Risk-weighted amount: zero.

Twenty percent weight. Mortgage-backed securities issued by Fannie Mae and Freddie Mac, $150 million; general obligation municipal bonds, $50 million. Risk-weighted amount: $40 million.

Fifty percent weight. First-lien residential mortgages that meet prudent underwriting standards, $380 million. Risk-weighted amount: $190 million.

One hundred percent weight. Commercial real estate loans, $260 million; commercial and industrial loans, $120 million; consumer loans, $40 million; construction loans, $20 million; premises and other assets, $30 million. Risk-weighted amount: $470 million.

Off the balance sheet. Unused loan commitments of $80 million, converted at 50 percent and weighted at 100 percent, add $40 million.

Total risk-weighted assets: $740 million, or about 62 percent of total assets.

Capital Measured Two Ways

Capital to total assets. $114 million of tier 1 capital divided by $1.2 billion of assets is 9.5 percent, above the framework's 9 percent requirement by half a point, or about $6 million of capital.

Risk-based ratios. Tier 1 capital divided by risk-weighted assets is 15.4 percent, against a well-capitalized threshold of 8 percent. Adding the allowance for credit losses, $9 million, to reach total capital gives a total capital ratio of 16.6 percent, against a threshold of 10 percent. On risk-based measures, the bank holds roughly twice the capital it needs to be well capitalized.

What Each Measure Captures

The two measures answer different questions. The capital-to-assets ratio asks how much of every asset is funded by owners rather than depositors, regardless of what the asset is; it guards against a bank growing large on a thin layer of equity and against errors in risk weights. The risk-based ratios ask whether capital is sufficient for the credit risk actually held, so a bank full of Treasuries needs less than one full of construction loans. Neither is complete alone, which is why the standard rules apply both. The simplified framework drops the risk-based side in exchange for a higher bar on the simple ratio, a trade that suits banks with ordinary loan books but penalizes those whose growth comes from low-risk assets.

The Mortgage Plan

The board wants to grow residential mortgage lending by $150 million over the next year, funded by deposits from a new branch. Mortgages carry a 50 percent risk weight, so the plan adds $75 million of risk-weighted assets.

Under the CBLR. Assets rise to $1.35 billion. With capital unchanged, capital falls to 8.4 percent of assets, below 9 percent. The framework allows a two-quarter grace period for a bank whose ratio slips to between 8 and 9 percent, after which it must either restore the ratio or comply with the risk-based rules. Retaining a year's earnings, about $14 million less $5 million of dividends, would lift capital to $123 million and the ratio to about 9.1 percent, a margin too thin to rely on.

Under the risk-based rules. Risk-weighted assets rise to $815 million. The tier 1 ratio falls from 15.4 to about 14.0 percent, still far above the 8 percent threshold.

The plan adds mostly low-risk assets, so the risk-based rules barely notice it, while the CBLR, which weighs every dollar alike, pushes the bank below its line; the bank's capital is ample, but the framework it chose for simplicity has become the constraint.

The Options

Stay in the framework and slow the plan. Holding capital at about 9.25 percent of assets after retaining earnings would allow roughly $130 million of growth, not $150 million, and would leave no room for deposit inflows that swell the balance sheet without new lending.

Stay in the framework and cut the dividend. Suspending the $5 million dividend would add capital but signal stress to shareholders that the bank's risk-based position does not justify.

Leave the framework. The bank can opt out and report full risk-based ratios. The cost is reporting: the detailed regulatory capital schedule, systems to assign risk weights to every exposure, and staff time, estimated at about $60,000 a year. In exchange, the bank's binding constraint would become the risk-based ratios, where it holds a cushion of more than $60 million above well-capitalized levels, and the 5 percent capital-to-assets threshold that applies under the standard rules.

Why Capital Cushions Matter Beyond the Rules

Research on banks during financial crises finds that higher capital helped smaller banks gain market share and survive, and improved their performance in normal times as well (Berger & Bouwman, 2013). The analysis should not treat the risk-based surplus as idle capital to be used up. It does show, though, that the bank's capital is adequate for the plan; the CBLR's limit reflects the framework's simplicity, not the bank's risk.

Concentration Check

Commercial real estate loans of $260 million equal about 211 percent of tier 1 capital plus the allowance, below the 300 percent level at which supervisors expect heightened risk management. The mortgage plan does not change that figure, but any shift toward commercial real estate would.

Recommendation

Opt out of the CBLR before the mortgage program begins, invest in risk-based reporting, and keep the dividend. Set an internal floor of a 12 percent tier 1 risk-based ratio and tier 1 capital of at least 7.5 percent of assets, well above regulatory thresholds, and review both quarterly as the mortgage book grows.
