Bank of America says bond losses expanded in the third quarter, exceeding $100 billion as rates rose

Bank of America’s bond losses broadened to more than $100 billion in the third quarter, according to a report by Yahoo Finance published Oct. 14. The coverage ties the increase to a rise in interest rates, which can reduce the market value of longer-dated bonds and other fixed-income securities when yields move higher.

The article characterizes the pattern as rooted in the bank’s pandemic-era decisions, when yields were at historic lows and financial institutions shifted into large volumes of long-duration debt. In that environment, acquiring bonds with longer maturities can improve carry income, but it also increases sensitivity to later rate increases, because those longer-dated securities tend to reprice more sharply when yields rise.

Although the Yahoo report frames the issue around what it calls a “blunder” during the Covid era, the post itself does not provide additional detail in the excerpt available here, including which specific portfolios or balance-sheet lines drove the change, how the losses are measured (for example, unrealized versus realized), or whether management is offsetting the exposure through hedges or shorter-duration redeployments.

For investors and credit analysts, bond-loss figures matter because they can affect both accounting earnings and regulatory capital, depending on how the securities are classified and how losses flow through financial statements. Mark-to-market declines can also influence funding and liquidity discussions, particularly when a bank’s balance sheet includes substantial holdings that react to rate swings.

The broader banking sector has faced this exact tension since the rapid post-pandemic increase in rates. As Treasury and other government yields moved higher, banks holding large fixed-income portfolios experienced unrealized losses, while those losses could differ across institutions based on their duration mix, purchase timing, and the size and structure of interest-rate hedges.

Bank of America did not disclose in the Yahoo post excerpt any further context on the bank’s risk-management actions tied specifically to this quarter, such as adjustments to average duration, changes to hedge ratios, or the extent to which losses may reverse as securities run off or are held to maturity.

There is also an important limitation in what is reflected in the available reporting here: the excerpt does not show the underlying management commentary, the precise accounting categories involved, or how much of the losses are concentrated in specific sectors or instruments. That means it is not possible from the information available here to judge the permanence of the losses or the likely impact on future earnings outcomes.

What to watch next is whether Bank of America provides more granularity in subsequent filings or investor materials, including how management explains the timing and measurement of bond losses, what hedging is in place, and whether the bank’s trajectory for interest-rate risk management is changing. Any follow-on disclosure that separates unrealized declines from realized losses, or that clarifies potential earnings resilience, would help investors assess how large the economic impact may be beyond accounting measures.
