What is the Tier 1 Risk-Based Capital Ratio?

The Tier 1 Risk-Based Capital ratio measures a bank's Tier 1 capital (CET1 plus Additional Tier 1 instruments) against its risk-weighted assets. It is the broader of the two Tier-1 capital measures and is still the headline capital metric for most banking comparisons.

Read Tier 1 RBC alongside CET1: a large gap between them means the bank relies meaningfully on preferred stock for its capital base, which is more expensive and less flexible than common equity. Most community banks show Tier 1 RBC within a few basis points of CET1. The bands below are BankRegReports analyst bands, not prompt corrective action categories; PCA treats a Tier 1 ratio of 8% or more as well capitalized.
