Services revenue rose 15%, and wealth management return on tangible common equity (ROTCE) topped 14%. The bank raised its full-year ROTCE guidance to above 11%, with a medium-term target of 11-13% for 2027-2028. It expects Markets revenue to fall about 20% in the fourth quarter, a typical seasonal decline. Expense growth was held to 3% excluding notable items. Citigroup booked over $1 billion in year-to-date severance and bought back $3 billion of shares in the third quarter alone. Its CET1 capital ratio stood at 12.8%. The deconsolidation of Banamex in early 2027 is expected to be slightly accretive to that ratio despite a $9 billion currency translation adjustment loss.
Four of the biggest US banks reported higher third-quarter profits on Tuesday, but warned that higher interest rates and inflation could hurt consumers and the economy. JPMorgan Chase, the largest US bank by assets, earned $15.3 billion, or $5.57 a share, up from $14.4 billion a year earlier. It missed analyst forecasts of $5.93 a share, its first miss in nearly three years. Goldman Sachs posted a profit of $5.29 billion, up from $4.1 billion, as equities revenue jumped 72%. Wells Fargo earned $5.95 billion and beat forecasts, while Citigroup's profit rose 40%. JPMorgan chief executive officer Jamie Dimon cited "large fiscal deficits, sticky inflation, elevated asset prices, rising interest rates and geopolitical conditions.

Memory stocks fell for a second day after a Chinese chipmaker, CXMT, said it had made a breakthrough in memory chip production. Roundhill Memory ETF fell more than 5% in premarket trading. UnitedHealth rose more than 2% after it earned an adjusted $4.69 per share on $112.69 billion in revenue, beating estimates. It raised its full-year earnings outlook to at least $20.50 per share. Goldman Sachs gained more than 3% on strong results. JPMorgan Chase, Wells Fargo, and Citigroup fell short in parts of their reports. Johnson & Johnson fell 2% after $25.40 billion in sales narrowly missed estimates, though it raised its full-year forecasts.
Citigroup Inc.'s fixed-income traders posted their best third quarter in at least a decade, beating analyst expectations. Trading desks for bonds, currencies and commodities brought in $4.4 billion, against an average estimate of $4.3 billion. Rival JPMorgan Chase & Co. reported a surprise drop in fixed-income trading revenue the same day, its first in more than two years. Citi's services business saw revenue rise 15% to $6.6 billion. Merger advisory revenue fell 4%. Total revenue rose about 8% to $23.8 billion, above the $23.7 billion estimate. Earnings per share were $2.85, against an estimate of $2.65.

DailyPay, the on-demand pay provider, has completed a $200 million asset-backed securitisation of its receivables. This marks the company's second such transaction, following a $200 million securitisation in June 2025. The New York-based firm now has approximately $1.4 billion in debt financing backed by its on-demand pay receivables, including a $960 million secured credit facility. DailyPay is the only on-demand pay provider to access the asset-backed securitisation market. The company serves more than 2,000 employers and over 6 million employees. Its platform allows workers to access wages they have already earned before payday, with DailyPay funding the transfers without affecting employer cash flow. Citi acted as lead bookrunner and structuring agent for the transaction.
