U.S. banks collectively earned $80 billion in the first quarter of 2026, but a growing shadow hung over their balance sheets: unrealized losses on investment securities hit $325.1 billion by the end of March. That figure rose for the second straight quarter, according to federal data released Wednesday.
The growing gap in bank securities
Unrealized losses represent the paper decline in the market value of bonds and other securities that banks hold, typically long-term government debt bought when interest rates were lower. They aren't realized losses — banks don't have to sell at a loss — but they erode capital buffers and spook regulators. At $325.1 billion, the total is up from the prior quarter and remains near historic highs.
The profit number, $80 billion for the three months ending in March, shows the industry is still generating healthy income from lending and fees. But the persistence of those paper losses suggests the banking sector hasn't shaken off the interest-rate hangover that rattled markets in 2023.
Why the losses keep rising
The Federal Reserve's campaign to tame inflation kept rates elevated through late 2025 and into early 2026. As the central bank held its benchmark rate steady, the market value of older, lower-yielding bonds continued to slide. Banks that loaded up on Treasury and mortgage-backed securities during the pandemic era are sitting on portfolios that are now worth far less than their purchase price.
Regulators have pressed banks to shore up capital and disclose those losses more transparently. The second consecutive quarterly increase suggests that, despite some banks trimming their holdings, the overall industry hasn't turned the corner.
What the profit figure masks
The $80 billion profit for Q1 2026 is a solid number — it shows core lending and fee income are still flowing. But analysts who track the sector point out that profit was likely boosted by one-time gains and lower provisions for loan losses, not by a fundamental improvement in the securities book.
Small and regional banks, in particular, remain exposed. They hold a larger share of their assets in securities compared to the megabanks, and many are still working through the mismatch between the low yields they locked in years ago and the high rates they now pay on deposits.
The Federal Deposit Insurance Corporation, which compiles the data, said the industry's net interest margin — a key measure of lending profitability — narrowed slightly in the quarter, signaling that pressure on earnings could build if rates stay high.
Banks face a tricky balancing act. If the Fed cuts rates later this year, as some forecasters expect, the market value of those securities would rebound, shrinking the unrealized losses. But if rates stay elevated, the losses could keep growing — and some banks may eventually have to sell at a loss to meet liquidity needs.
Regulators are expected to release updated stress test results in June, which will show how the largest banks would fare under a severe recession scenario. Those results will include the impact of unrealized losses on capital ratios, giving investors a clearer picture of which institutions are most vulnerable.
For now, the industry is profitable but not out of the woods. The next quarterly report, due in August, will show whether the trend of rising unrealized losses has finally peaked.
