How to read these figures
Net interest margin is what the bank earns on loans and securities minus what it pays for deposits and borrowings, as a share of earning assets. Return on assets and return on equity measure profitability. The efficiency ratio is non-interest expense over revenue — lower is better. The Tier 1 leverage ratio is core capital against average assets, a key gauge of how much loss a bank could absorb.
These come from the bank’s regulatory call report and reflect the FDIC-insured bank subsidiary only. New to these terms? The Oxford Ledge lessons walk through bank financials and credit from the ground up, and all tracked banks are ranked by assets.
