Regulatory Capital [Abstract]  
REGULATORY CAPITAL REGULATORY CAPITAL
Citigroup is subject to risk-based capital and leverage standards issued by the Federal Reserve Board, which constitute the U.S. Basel III rules. Citi’s U.S.-insured depository institution subsidiaries, including Citibank, are subject to similar standards issued by their respective primary bank regulatory agencies. These standards are used to evaluate capital adequacy and include the required minimums
presented in the following table. The regulatory agencies are required by law to take specific, prompt corrective actions with respect to institutions that do not meet minimum capital standards.
The following table presents for Citigroup and Citibank the regulatory capital tiers, total risk-weighted assets, quarterly adjusted average total assets, Total Leverage Exposure, risk-based capital ratios and leverage ratios:

N/A  Not applicable
As indicated in the table above, Citigroup and Citibank were “well capitalized” under the current federal bank regulatory agencies definitions as of December 31, 2025 and 2024.

Banking Subsidiaries—Constraints on Dividends
There are various legal limitations on the ability of Citigroup’s subsidiary depository institutions to extend credit, pay dividends or otherwise supply funds to Citigroup and its non-bank subsidiaries. The approval of the Office of the Comptroller of the Currency is required if total dividends declared in any calendar year were to exceed amounts specified by the agency’s regulations.

In determining the dividends, each subsidiary depository institution must also consider its effect on applicable risk-based capital and leverage ratio requirements, as well as policy statements of the federal bank regulatory agencies that indicate that banking organizations should generally pay dividends out of current operating earnings. Citigroup received $12.7 billion and $5.5 billion in dividends indirectly from Citibank through its holding company during 2025 and 2024, respectively.
