Bank of America earned USD 9.1bn in a quarter, but its equity grew by less than that in a whole year

Profit is up sharply, the cushion is not

Bank of America is one of the largest banks in the United States. It takes deposits, lends to households and companies, manages wealth and runs an investment bank. In the second quarter of 2026, the three months to the end of June, it made USD 9.1bn of net profit. That is 26.6% more than in the same quarter of 2025, on revenue that rose 15.0% to USD 31.6bn. The figures cover the whole group, consolidated under US GAAP, in US dollars.

The balance sheet tells a quieter story. Equity, the owners' stake in the business, stood at USD 301bn at the end of June 2026, against USD 298bn a year earlier. Over twelve months it grew by USD 3.1bn, or 1.0%. That increase is smaller than the profit of the latest quarter on its own.

Total assets reached USD 3,499bn. Equity therefore covered 8.6% of them, down from 8.7% a year before, a change of -0.1 pp. Everything else on the asset side is funded by other people's money: depositors, bondholders and other creditors.

So the bank is earning more than it did a year ago, and its owners' cushion is not getting any thicker in relation to what it carries. That is the tension in these accounts. A business that makes this much money could build a much larger buffer. It chooses not to.

A thin layer is how banks are built

For a manufacturer or a retailer, equity of 8.6% of total assets would be a warning sign. For a large bank it is ordinary. A bank's raw material is borrowed money. Customer deposits sit on the balance sheet as liabilities, and the bank lends them on at a higher rate than it pays. The more assets it funds with deposits and bonds rather than owners' capital, the more profit each dollar of equity earns.

That is the attraction of a thin layer. The same profit spread over a smaller equity base produces a higher return on equity, the figure shareholders watch most closely. It is also the risk. Equity is what absorbs losses before depositors and bondholders are touched. When it covers only a small slice of the balance sheet, a fall in the value of the assets of a similar size would wipe it out.

Why did equity barely move in a year of rising profit? Profit leaves a bank in a few ways. Large US banks pay dividends and buy back their own shares, often handing most of their earnings back to shareholders when regulators judge their capital sufficient. Equity can also shrink when the market value of bonds the bank holds falls, a loss that passes through equity without touching the income statement. The headline figures do not show which of these ate the difference; the statement of changes in equity in the quarterly report splits it into dividends, buybacks and other movements.

The income statement at least shows that the gap is not a sign of weak earnings. The net margin, the share of revenue left as net profit, widened by 2.6 pp to 28.8%, from 26.1% a year earlier. Revenue grew and more of each dollar of it reached the bottom line. The money was made. It simply did not stay on the balance sheet.

Regulators do not judge banks by this simple ratio alone. They weigh assets by risk, so a government bond counts for less than an unsecured corporate loan, and they set minimum capital against that weighted total. Equity over total assets is the blunt version of the same question: how much of the balance sheet belongs to the owners, without any adjustment for how risky the rest is.

The bond market adds context. Kurzy.cz reported in October 2026 that Bank of America returned to the bond market only days after a large issue, this time offering perpetual bonds with an investment-grade rating. Perpetual bonds have no maturity date and rank below ordinary debt, which is why banks commonly use them to add loss-absorbing capital without issuing new shares. I would not read that as a sign of trouble. It looks more like a bank that manages its cushion deliberately: profit goes out to shareholders, and the buffer regulators require is topped up with instruments that cost less than fresh equity. In the same week Kurzy.cz reported that Michael Hartnett, a strategist at the bank, expected investors to lean towards caution for some weeks. A thin cushion is a comfortable choice in calm markets and a less comfortable one when they turn.

What to check in your own company

Your company is almost certainly not a bank, which makes the exercise more useful, not less. A bank has regulators, stress tests and a central bank behind it. You have your lenders and your own judgement.

Start with your latest balance sheet and income statement. First, divide equity by total assets. That is your equity ratio, the share of what the company owns that is funded by its owners rather than by suppliers, banks and the tax office.

Second, compare the change in equity over the last year with the net profit for the same year. If equity grew by much less than profit, find out where the difference went: dividends, a loan to the owner, a revaluation, a loss in a subsidiary. Each of these is legitimate. You should simply be able to name it without hesitation.

Third, ask the question the bank's regulators ask in their stress tests. How large a loss could your equity absorb before it turns negative? Compare that amount with your worst year of the past decade, or with the loss of your largest customer for twelve months. If the answer makes you uncomfortable, the ratio is not efficient, it is exposed.

Then open your loan agreements. Many bank loans to companies set a minimum equity ratio or a maximum ratio of debt to earnings. Find the clause, note the threshold and work out how far a bad year would take you towards it. Breaching a covenant rarely ends a business. It does hand the next conversation to the lender.

Bank of America shows that a thin equity layer is a choice, not an accident, and that a very profitable year does not have to make it any thicker. The bank can make that choice with regulators and a deep bond market behind it. Most companies cannot, so they should at least know their own ratio before someone else calculates it for them.
