The OFR released a brief today entitled, "A Comparison of U.S. and International Global Systemically Important Banks." Among global systemically important banks (G-SIBs), U.S. banks rank high in systemic importance relative to foreign banks. G-SIBs with higher systemic importance scores do not consistently have higher risk-based capital ratios, despite the importance of capital as a buffer against failure.
