Capital One Financial Corporation (COF)
Capital One Financial is a bank. Most of its business is credit cards. It lends money to people who want to buy things but do not have the cash, and it charges them interest. Many of its customers have damaged credit — they have missed payments in the past, or they carry high balances, or they are young and have no credit history. Traditional banks consider these people too risky to lend to. Capital One disagrees.
The company bets that it can figure out which risky customers will repay and which will not. If it is right, it charges them a higher interest rate that covers the losses from the ones who default, plus operating costs, plus profit. If it is wrong, customers stop paying and the losses pile up.
What Capital One actually does
Capital One issues credit cards and other consumer loans. When you apply for a Capital One card, the company runs your credit. If you have bad credit, Capital One might still approve you — but it will charge you a higher interest rate. When you carry a balance on your card, Capital One earns interest on that balance. If you pay the full amount due each month (called paying in full), Capital One earns nothing from you except a small merchant fee when you use the card.
Capital One also makes auto loans — lending money to people who need to buy a car. Here again, it targets people banks are less eager to lend to. It also operates a small retail bank where customers can deposit money and earn interest (though Capital One does not primarily compete in traditional banking).
The business is simple. Money flows in from interest and fees. Money flows out as operating costs (salaries, technology, marketing) and credit losses (when customers do not pay back what they borrowed). If income exceeds costs and losses, Capital One is profitable. If losses get too high, it is not.
The credit card market and margins
The credit card market is divided into segments. Prime customers have high credit scores, low debt, and strong histories of paying on time. They get low interest rates (maybe 15 to 18 percent annually). Banks do not make much money on them because the default risk is low and competition among banks to serve them is fierce.
Non-prime customers — people with lower credit scores, higher debt, or weaker payment histories — get higher interest rates (maybe 25 to 29 percent annually). Banks make more money on each dollar lent, because they are charging more to cover the higher default risk.
Capital One targets non-prime customers. It is willing to lend to people the biggest banks will not touch, in exchange for higher rates. This is not charity. Capital One expects some customers to default, and it prices accordingly.
The metric that captures this is the net interest margin — the difference between what the bank earns on its loans (the interest rate) and what it pays on deposits and borrows in the wholesale market. Capital One’s margins are wider than a prime-focused card issuer like American Express because it lends to riskier people at higher rates.
Credit losses and the risk model
Credit losses are the reason not everyone wants to lend to non-prime customers. When someone gets a Capital One card, takes a balance, and then stops paying, Capital One loses the money it lent. This happens constantly. In any given quarter, Capital One’s credit losses are typically hundreds of millions of dollars, sometimes over a billion.
The company has to predict, in advance, how many customers will not pay, and how much it will lose from them. This is modeled as a charge-off rate — the percentage of the portfolio that is written off as uncollectible — and the company sets aside reserves for expected losses. If losses turn out higher than expected, the company has to take a charge that reduces earnings. If losses are lower, it releases reserves and earnings are boosted.
This makes Capital One’s earnings volatile. In good economic times, when unemployment is low and people are spending freely, credit losses can be surprisingly mild. In recessions, they spike. The company also faces model risk — if its model of which customers will default turns out to be wrong, it can misprice risk across its entire portfolio.
How the numbers work
A simplified example: say Capital One issues 1 million credit cards with an average balance of 5,000 dollars. That is 5 billion dollars outstanding. The average interest rate is 20 percent annually. That generates 1 billion dollars of interest income per year.
Operating costs — technology, customer service, marketing to acquire customers, compliance — might run 300 million dollars per year.
Credit losses might run 150 million dollars per year (a 3 percent charge-off rate, meaning 3 percent of the balance will not be repaid).
That leaves roughly 550 million dollars of pre-tax earnings on the 5 billion outstanding. That is a 11 percent return on the portfolio.
In practice, Capital One’s portfolio is much larger (hundreds of billions of dollars), and the numbers are more complex. But this is the shape of the business.
Growth through acquisition and expansion
Capital One was created in 1988 as a division of a Virginia bank. It spun out and went public, and then grew partly through issuing more cards to existing customers and acquiring more customers, and partly by buying other banks and card portfolios. In 2005, Capital One acquired North Fork Bancorporation, a major bank, and this transformed the company from a pure card issuer into a retail bank with deposits. In 2013, it acquired ING USA, a retail bank, further expanding its deposit base.
This expansion into traditional banking was strategic. It gave Capital One a large source of cheap deposits (people’s savings accounts) that it could use to fund lending, which is much cheaper than borrowing in wholesale markets. A traditional bank funded by deposits has a different economics than a pure card issuer that borrows money wholesale.
However, this also made Capital One subject to more regulation. Traditional banks are overseen by the Federal Reserve and other regulators, and they have to maintain minimum capital ratios, undergo stress tests, and follow rules around how much they can lend. A pure card issuer is less regulated.
Pressure and risk
Capital One faces multiple pressures. Interest rates set by the Federal Reserve influence both the cost of deposits and the rates Capital One charges customers. If the Fed raises rates, Capital One’s costs on deposits may rise, which can squeeze margins. But it also increases the rates the company can charge new borrowers. The net effect is complicated and depends on the timing and shape of rate changes.
Regulatory scrutiny is another risk. There have been periods when regulators have pushed banks to tighten lending to subprime borrowers, concerned about predatory lending or about economic instability. Capital One’s core business is subprime, so any regulatory crackdown hits the company directly. In 2019, Capital One suffered a major data breach exposing information on millions of customers, which increased regulatory pressure and customer-service challenges.
Economic recession is an existential risk for a consumer lender. In a recession, unemployment rises, people lose income, and default rates spike. Capital One can lose billions of dollars in a severe recession. The company has stress-tested itself against various economic scenarios, but stress tests are backward-looking; an unprecedented crisis could be worse.
Competition is also intense. Fintech companies have entered consumer lending, using data science and mobile apps to compete with traditional banks. Credit unions and large banks are also competing for customers.
How to research Capital One
The company’s annual 10-K filing (SEC CIK 0000927628) contains detailed disclosures about its loan portfolio, charge-off rates, and loss reserves. Read the section on credit exposure carefully — it should break down loans by credit score band, by geography, by age, and by how recently they were originated. Pay attention to trends in charge-off rates and delinquency rates (the percentage of customers who are late on payments).
Watch the net interest margin. This is the spread between what the company earns on loans and what it pays on deposits. A widening margin is good for earnings; a narrowing margin is pressure.
Read the management discussion of the current economic environment and what management expects to happen to credit losses. In good times, losses are low and you might see management talking about how resilient the portfolio is. In downturns, management becomes more cautious.
Look at the deposit base and funding costs. Capital One has shifted over time to being more a traditional retail bank funded by deposits rather than a pure wholesale-funded card issuer. That is generally more stable but reduces the yield on assets.
Finally, note that Capital One is a loan growth story. The company grows earnings by making more loans and by maintaining credit discipline. It survives when it correctly sizes risk and prices for it. It dies when it messes up.
