12 CFR § 628.10 - Minimum capital requirements.

(1) A common equity tier 1 (CET1) capital ratio of 4.5 percent.
(2) A tier 1 capital ratio of 6 percent.
(3) A total capital ratio of 8 percent.
(6) A permanent capital ratio of 7 percent.
(4) Tier 1 leverage ratio. A System institution's leverage ratio is the ratio of the institution's tier 1 capital to the institution's average total consolidated assets as reported on the institution's Call Report minus amounts deducted from tier 1 capital under §§ 628.22(a) and (c) and 628.23.
(5) Permanent capital ratio. A System institution's permanent capital ratio is the ratio of the institution's permanent capital to its total risk-adjusted asset base as reported on the institution's Call Report, calculated in accordance with the regulations in part 615, subpart H, of this chapter.
