Citigroup is among five financial institutions that failed the second round of the Federal Reserve Annual stress tests.
The Comprehensive Capital Analysis and Review shows a bank's ability to project future revenue and losses in a financial crisis situation.
This year, Citigroup, along with HSBC North America Holdings, RBS Citizens Financial Group, Santander Holdings USA and Zions failed to meet the Fed's requirements.
Overall, 25 out of 30 banks passed the test.
The results follow last week's Dodd-Frank stress test results, which show whether banks have enough capital on hand to deal with a major economic downturn.
Twenty-nine out thirty banks passed that test.
