Quick Navigation
If you've been following Berkshire Hathaway's portfolio, you know Bank of America (BAC) is the second-largest holding after Apple. But why did Warren Buffett pile into a bank that nearly collapsed during the financial crisis? I've spent years studying Berkshire's moves, and I can tell you – this wasn't a random bet. It was a calculated play on America's economic engine.
Why Buffett Bet on BAC
Back in 2011, when Buffett invested $5 billion in Bank of America preferred stock, the bank was still licking its wounds from the subprime mortgage mess. Most investors ran away. But Buffett saw something else: a massive deposit base, a recovering economy, and a management team (led by Brian Moynihan) that was focused on cleaning up the balance sheet.
Buffett's move wasn't just a rescue – it was a vote of confidence. He negotiated a 6% dividend on the preferred shares and got warrants to buy 700 million common shares at $7.14 each. Over time, Berkshire converted those warrants and added more shares. Today, Berkshire owns over 1 billion shares of BAC, making it the largest shareholder.
The Size of the Stake
Let me put some numbers on the table. As of the most recent filings, Berkshire holds about 1.03 billion shares of BAC, which is roughly 13% of the company. At the current price (around $40), that stake is worth over $41 billion. It's a monster position, and it paid off handsomely – Berkshire's cost basis is well under $10 per share after factoring in the preferred dividends.
| Metric | Value |
|---|---|
| Shares Held | 1.03 billion |
| Ownership % | ~13% |
| Estimated Cost Basis | ~$7.14 per share (warrants) plus preferred dividends |
| Current Market Value | ~$41 billion |
| Annual Dividend Income (estimated) | ~$900 million |
But here's a nuance most people miss: Berkshire also has a huge unrealized gain. That gain, however, is not reflected in Berkshire's book value because accounting rules only mark-to-market a portion of the equity portfolio. This distortion often confuses investors trying to value Berkshire itself.
BAC vs Other Bank Holdings
Berkshire also owns major stakes in other banks like American Express, Bank of New York Mellon, and U.S. Bancorp. But BAC is the biggest pure-play bank. Why BAC over, say, JPMorgan Chase? I've asked myself that many times. Looking at the numbers, BAC's return on tangible common equity (ROTCE) consistently beats JPM's. Plus, BAC has a massive retail deposit network, which funds its lending at a low cost. That's a moat.
Another point: Buffett actually sold some BAC shares in 2020 during the pandemic – a move that surprised many. He later admitted it was a mistake, as BAC rebounded strongly. Since then, he's been a net buyer again, quietly adding to the position.
Key Metrics That Matter
When I analyze BAC as a Berkshire holding, I focus on three things:
- Net Interest Income (NII): BAC earns a spread on deposits and loans. With higher interest rates, NII skyrocketed. That's a tailwind Buffalo loves.
- Efficiency Ratio: BAC targets an efficiency ratio below 60%. It's been hovering around 58%, meaning it's cost-efficient.
- Buyback Yield: BAC aggressively repurchases shares. In 2023 alone, it bought back $20 billion worth. That directly benefits Berkshire's per-share value.
Here's a table that shows the trend over the last few years:
| Year | Net Income (billion) | Buybacks (billion) | ROTCE |
|---|---|---|---|
| 2020 | 17.9 | 19.5 | 10.5% |
| 2021 | 32.0 | 25.5 | 16.0% |
| 2022 | 27.5 | 25.0 | 14.2% |
| 2023 | 26.5 | 20.0 | 13.8% |
Notice that earnings dipped in 2023 due to higher provision for credit losses. But Buffett doesn't sweat a bad year – he's playing the long game.
Risks and Criticisms
No investment is perfect. I've read critiques arguing that BAC is too dependent on net interest income, and if the Fed cuts rates sharply, earnings will take a hit. That's true. There's also regulatory risk – tighter capital requirements could limit buybacks.
But the biggest risk I see is concentration. Berkshire already has over 40% of its portfolio in Apple. Adding a huge BAC stake means the fate of Berkshire's stock is tied to two companies. Buffett himself has said that diversification is not his game – he bets big on high-conviction ideas. Still, for a conservative investor, that heavy weighting might be unnerving.
Another criticism: BAC's commercial real estate exposure. With office vacancies rising, some worry about loan losses. I think the fears are overblown because BAC's CRE loans are well-diversified, but it's worth watching.
What It Means for Investors
If you're thinking of following Buffett into BAC, here's my take: BAC is a solid bank with a strong franchise and a shareholder-friendly management. But buying BAC just because Buffett owns it is a lazy strategy. Understand why you're buying. For me, BAC fits into a portfolio as a cyclical value play – it does well when the economy hums, and it pays a decent dividend while you wait.
One thing I learned from studying Buffett: he doesn't try to time the market. He bought BAC when it was cheap, and he held through volatility. If you can stomach the ups and downs, BAC could be a long-term compounder. But don't expect Tesla-like returns. This is a tortoise, not a hare.
