Capital
Risk-Weighted Assets
Also known as RWA
Risk-weighted assets (RWA) are a bank's assets and off-balance-sheet exposures scaled by their credit risk. RWA is the denominator of every risk-based capital ratio, so it determines how much capital a bank must hold.
Formula
Each asset gets a risk weight set in 12 CFR Part 217 — 0% for cash and Treasuries, 20% for agency MBS, 50% for many mortgages, 100% for most commercial loans, up to 1,250% for some securitizations. Schedule RC-R sums the weighted exposures into total RWA.
Why it matters
RWA translates a bank's asset mix into a single risk-adjusted base. Two banks with identical total assets can have very different RWA — a Treasury-heavy bank far less than a commercial-loan-heavy one — and therefore very different capital requirements.
How to interpret
Read RWA against total assets: 'RWA density' (RWA ÷ assets) reveals how risky the balance sheet is. A high density signals a loan-heavy, higher-risk mix; a low density signals a securities-heavy, lower-credit-risk book — though that book may still carry interest-rate risk that RWA ignores.
Thresholds
| Range | Label | Interpretation |
|---|---|---|
| Low density (< 50%) | Conservative mix | Asset base tilted to low-risk-weight holdings. |
| 50-70% | Typical | Balanced asset mix for a commercial bank. |
| 70-90% | Loan-heavy | Higher-risk-weight, credit-intensive balance sheet. |
| > 90% | Aggressive | Dense, high-risk-weight book demanding more capital. |
Worked example
Frequently asked
Why use risk-weighted assets instead of total assets?
Total assets treat a Treasury bill and a construction loan identically. Risk-weighting scales each exposure by its credit risk so capital requirements track the actual riskiness of the balance sheet.
Does RWA capture interest-rate risk?
Largely no. RWA is built around credit risk (plus market and operational risk at large banks). The interest-rate risk that drove 2023's unrealized losses is not reflected in standard RWA, which is why the leverage ratio and AOCI matter alongside it.
