Citigroup posts best Q3 revenue in a decade, lifts ROTCE guidance above 11%

Citigroup reported its best third-quarter revenue in a decade for 2026, with four of its five core businesses growing. 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.

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.
