Financial data company Bloomberg ranked the banks in the US, and Citigroup came out on top. The bank also finished 9^th in the world, while the top spot worldwide went to Qatar National Bank.

Ratings for strongest US bank were based on five criteria: Tier 1 Capital to Risk-Weighted Assets Ratio, Nonperforming Assets, Loan Loss Reserves, Deposits to Funding Ratio, Efficiency (Costs to Revenue) Ratio. The ratings are based on fiscal year 2012.

The Tier 1 ratio accounted for 40% of the score, and Citigroup’s high score is related to the bank’s recent offloading of bad assets.

Here’s Bloomberg’s ranking of the Top 10 Strongest Banks:

1. Citigroup
2. JP Morgan Chase
3. Huntington Bancshares
4. Zions Bancorporation
5. KeyCorp
6. US Bancorp
7. Bank of America
8. Regions Financial
