Reading a Bank's Balance Sheet
Loans as Assets, Deposits as Liabilities
Schedule RC, the balance sheet section of the public call report, is where a bank lays out what it owns and owes, so I pulled one up to see how it is put together. I've read balance sheets before from my startup days, but a bank's looks different in several ways.

Assets
The first thing that jumped out is what counts as an asset. In a typical company, assets are things like cash, equipment, and intellectual property. At a bank, the biggest asset category by far is loans. More than half of total assets are money the bank has lent out. From an accounting standpoint, every loan is a promise from a borrower to pay the bank back, and that promise is an asset.
After loans, the next biggest category is securities, mostly bonds. Treasuries, agency mortgage-backed securities, municipal bonds. Then there's cash and balances due from other banks, which is a smaller piece than I expected.
What takes a moment to absorb is that almost everything on the asset side represents money other people owe the bank. The building, the ATMs, the technology infrastructure, all of that barely registers as a line item. The balance sheet is almost entirely financial assets.
Liabilities
This is where the inversion really hits. I knew deposits were liabilities from studying the business model, but seeing it on the balance sheet makes the scale concrete. Deposits aren't just the biggest liability. They're almost all of the liabilities, roughly 85 to 90 percent of total funding.
Every checking account, every savings account, every CD. The bank owes all of that money back. That's the deal. And that massive pool of obligations is what funds the loans on the other side of the ledger. When people talk about a bank "using depositors' money to make loans," this is literally what they mean. It's right there on Schedule RC.
The Equity Cushion
Equity is the gap between total assets and total liabilities. For a community bank, that gap is around 10 percent. For every dollar of assets, roughly ten cents is equity and ninety cents is funded by deposits and other borrowings.
Coming from industries where a 10 percent margin between what you own and what you owe would be alarming, this was striking. A typical tech company carries equity of 40 to 60 percent of total assets. Even in e-commerce, where the business is more capital-intensive, equity ratios tend to run 30 percent or higher. At a bank, it's 10. But it's been the norm in banking for a long time. The entire business model depends on managing that thin cushion carefully.
This also explains why regulators watch capital ratios so closely. When equity is 10 percent of assets, it doesn't take a large loss to create a real problem. A few bad loans can eat into that cushion fast.
What Stands Out
Reading through Schedule RC, what's clearest is where the concentration is. Loans are the dominant asset. Deposits are the dominant liability. Everything else is secondary.
It's also a kind of map. The loan portfolio is where the bank's largest financial exposure sits, which means credit quality, underwriting, and early detection of problems all matter enormously. The deposit base is where the funding comes from, which means understanding client behavior, predicting flows, and knowing which relationships are stable matters just as much.
The balance sheet doesn't tell you what to do. But it tells you where to look.
