Citigroup is a global bank that earns money in five main ways: helping big companies manage cash and move money across borders (Services), trading bonds and stocks for institutions (Markets), advising on deals and lending to corporations (Banking), managing wealth for rich clients (Wealth), and offering credit cards and loans to regular Americans (U.S. Personal Banking). It operates in nearly 160 countries and jurisdictions, which makes it one of the most geographically spread banks in the world. Revenue comes mostly from two sources: interest income, which is the money Citi earns on loans minus what it pays depositors, and fees charged every time a transaction happens. The diagram below traces where the money goes.

Five years of financial data tell a clear story about two separate trends running at the same time. Revenue has climbed steadily every single year, from $71.9 billion in 2021 to $85.2 billion in 2025. That is consistent growth of about 18% over the period. Net income also improved, reaching $14.3 billion in 2025 compared to $12.7 billion in the prior year.

But the cash flow picture tells a very different story. In 2021, Citi generated $43.0 billion in free cash flow. By 2022 that had fallen sharply to $19.4 billion. Then it flipped negative: negative $80.0 billion in 2023, negative $26.2 billion in 2024, and negative $74.2 billion in 2025. At the same time, net debt grew from $254.8 billion in 2021 to $344.0 billion in 2025. For a bank, some of this reflects the normal mechanics of how deposits and loans move through the balance sheet. But the scale and persistence of the negative free cash flow numbers are worth watching closely.
Why Banks Show Negative Free Cash Flow
Banks are not like regular companies. When a bank makes more loans, cash goes out the door. When customers deposit more money, that is counted as a liability. So a growing bank can show negative operating cash flow even while earning profits. This makes free cash flow a tricky number to read for financial institutions without understanding the full balance sheet.

Part of what is driving spending is a court-ordered cleanup. In 2020, U.S. regulators issued consent orders requiring Citi to overhaul its risk management, internal controls, and data systems. In 2024, regulators fined Citi an additional $61 million and $75 million for not making fast enough progress. By the end of 2025, Citi reported that over 80% of its transformation programs were at or nearly at their target state, and the OCC terminated one part of its 2024 amendment in December 2025. The transformation cost $3.3 billion in 2025 alone, up 14% from the prior year.

Regulators Issue Consent Orders
The Federal Reserve and the Office of the Comptroller of the Currency issued consent orders in October 2020 requiring Citigroup and its subsidiary Citibank to fix risk management, data quality, and internal controls. This triggered a multiyear, multi-billion dollar transformation program that is still running. In 2024, regulators added new fines and an amendment for slow progress. As of late 2025, one piece of that amendment was terminated, signaling partial progress.
The risks Citi faces are not abstract. They are specific and documented. The U.S. Personal Banking segment, which includes Citi's branded credit cards, generated about 12% of total revenues in 2025. If Congress passes a law capping credit card interest rates, that income shrinks directly. Citi's five largest credit card partnerships with retailers also account for 12% of company revenues. Losing even one of those partners could remove a significant chunk of income and trigger write-downs on related assets.

What a CET1 Capital Ratio Means
Regulators require banks to hold a minimum amount of their own money as a cushion against losses. The CET1 ratio (Common Equity Tier 1) measures how much of that cushion a bank has relative to its risky assets. A higher ratio means more safety. If regulators raise the minimum requirement, a bank must hold more capital and has less money available to pay dividends or repurchase shares.
Citi's CET1 capital ratio was 13.2% at the end of 2025, down from 13.6% at the end of 2024. If regulators tighten the rules around how much capital banks must hold, Citi would have less flexibility to return cash to shareholders through dividends and share repurchases. In 2025, Citi returned $17.6 billion to shareholders through $13.3 billion in share repurchases and $4.3 billion in dividends. Interest rate movements add another layer of risk: when rates fall, Citi earns less on its loans; when rates rise too fast, it can hurt borrowers and reduce the value of Citi's bond holdings.
Citi also holds $29.5 billion in deferred tax assets, which are future tax savings that only have value if the company generates enough taxable profit to use them. If profitability disappoints, some of that benefit could be lost.

The Bet
Citigroup's multiyear transformation succeeds fully and on time, satisfying regulators while holding expenses in check enough for revenue growth to flow through to the bottom line. Revenue has grown every year from 2021 to 2025, and the company reported positive operating leverage for 2025 for the second consecutive year. But the transformation bill is still rising, the FRB consent order remains in place, and the path from 80% complete to 100% complete has proven harder than the path to 80%. If the final stretch drags on, or if regulators identify new problems that require additional remediation, the cost base may keep growing at a pace that erodes the gains from higher revenue.
Open question
Citi is earning more revenue each year and has made real progress cleaning up its regulatory problems. At the same time, free cash flow has been deeply negative for three straight years, net debt keeps rising, and the transformation that regulators demanded is still not finished after five years. Can Citi complete its regulatory transformation quickly enough, and cheaply enough, that its growing revenue actually translates into durable improvement in cash generation and financial strength, or will the cleanup costs keep consuming the gains?

Regulatory Capital Requirements
The Federal Reserve Bank changes its rules about how much money Citi must keep on hand. If these rules get stricter, Citi will have less money available to return to shareholders through dividends and stock buybacks.
Credit Card Interest Rate Caps
Congress or regulators might pass a law that caps how much interest Citi can charge on credit cards. This would directly reduce revenues from Citi's credit card businesses, which generated about 12% of total revenues in 2025.
Co-Branding Partner Relationships
Citi's five largest credit card partnerships with retailers account for 12% of company revenues. If any major partner ends their agreement, Citi loses significant income and faces impairment losses on related intangible assets.
Interest Rate Movements
When interest rates fall, Citi earns less money on its loans. When rates rise too quickly, it hurts the economy and the value of Citi's bond holdings, reducing capital levels.
Deferred Tax Assets Realization
Citi has $29.5 billion in tax benefits that can only be used if the company generates enough taxable income. If Citi doesn't become profitable enough, it loses these benefits, directly reducing net income.
