Bond Market Volatility Drags Down Wall Street Fixed Income Trading; Bank of America's Unrealized Losses Widen to $109 Billion
nashnova research
Major U.S. banks posted broadly weaker fixed-income trading in Q3, with BofA's FICC revenue down 17% and its bond-portfolio unrealized losses swelling to $109 billion; Treasury yields hitting multi-decade highs crushed client activity, making rates the single biggest variable for bank earnings ahead.
Why did fixed-income trading stall across the board?
The 10-year Treasury yield posted its largest single-quarter rise since 2009, with rate volatility running high throughout Q3.
This means → bond prices kept falling with no clear direction, so clients sat on the sidelines and trading volume shrank.
FICC revenue fell broadly: BofA down 17%, Morgan Stanley down 7%, JPMorgan down 4%, Goldman roughly flat.
Citi was the sole outlier, with FICC revenue up 4% — driven by FX and spread products, not rates trading itself.
How do bank executives explain the slump?
Morgan Stanley CFO Sharon Yeshaya said rates rose "quite aggressively" in Q3, diverging sharply from the market's Q2 expectations, which sapped structured-trading demand.
BofA CFO Alastair Borthwick blamed a major shift in rates, citing "significant impact" on credit, mortgage, and municipal-bond FICC businesses.
In plain terms = the market had bet that rates were peaking — or even heading for cuts. Instead, rates kept surging. Those caught wrong-footed stopped trading, and volumes dried up.
What do $109 billion in unrealized losses actually mean?
BofA's bond portfolio — spanning mortgage-backed securities, Treasuries, and agency debt — carried $109 billion in unrealized losses at end-September, up sharply from $85 billion at end-June.
In plain terms = "unrealized losses" means the bank's bonds have fallen this much at market prices, but because they are classified as held-to-maturity (HTM — bonds the bank intends to hold until they pay back in full, rather than selling at market price), the losses do not yet show up as actual hits to earnings.
This means → as long as the bank is not forced to sell, the losses stay on paper. But their growing scale still raises concerns about whether BofA's capital cushion is thick enough — especially with its CET1 capital ratio (the key measure of a bank's ability to absorb shocks) already running below expectations.
Why did equities trading surge in the opposite direction?
In sharp contrast to fixed income: Goldman's equities trading revenue jumped 72%, JPMorgan's 49%, Morgan Stanley's 41%.
BofA and Citi saw more modest gains of 11% and 14%, respectively.
This reflects a rotation of capital and activity toward equities when the direction of rates is uncertain — the colder the bond market, the hotter the equities desk.
Can equities trading keep up this pace?
Oppenheimer analyst Chris Kotowski warned in a client note that these revenues carry "easy come, easy go" risk.
This means → equities trading surges typically depend on a specific environment — high volatility plus high turnover. Once conditions shift, revenue can snap back just as fast.
In plain terms = fixed income is losing money, equities are making money, but the equities windfall may not be reliable — the earnings outlook for big banks ultimately comes down to where rates go next.
