Common equity Tier 1, or CET1, is a bank's strongest capital — shareholders' equity that absorbs losses first and needs no repayment. Regulators set a minimum CET1 ratio (capital as a share of risk-weighted assets), because a bank that runs out of CET1 is insolvent.

| 22% | IMF warns that the AI boom's debt could turn a correction into a crisis 核心一级资本充足率 · 第 7 张术语卡 | In the IMF's stress scenario, banks with 22% of global banking assets would see CET1 ratios fall below 7% — the threshold that turns a capital problem into a solvency problem. CET1 是 2008 年之后监管改革的核心：以前银行可以用各种混合资本和内部模型「美化」资本充足率，现在最硬的指标就是普通股权益。读这个指标要注意分母 —— 风险加权资产。同一笔资本，如果银行把资产投向低风险权重项目（比如国债），CET1 比率会显得更高；所以「资本充足」有时是资产结构的选择，而不是资本真的变多了。这也是为什么压力测试要同时考察资产端的损失，而不只是看资本数字。 |
