What Is Risk-Weighted Assets?
A bank's total assets adjusted for credit risk, where safer assets like government bonds receive lower weights and riskier assets like commercial loans receive higher weights.
How It Works
Risk-weighted assets (RWA) are the denominator in capital ratio calculations. Rather than treating all assets equally, regulators assign risk weights that reflect the probability of default and expected loss. US Treasury securities carry a 0% risk weight because they are considered risk-free. Residential mortgages typically carry a 50% weight. Commercial and industrial loans carry 100%. Off-balance-sheet items like loan commitments and derivatives also receive risk weights.
This system means a bank with $10 billion in assets concentrated in government bonds will have far lower risk-weighted assets than a bank of the same size concentrated in commercial real estate loans. The RWA approach was introduced under the Basel I framework in 1988 and has been refined through Basel II and Basel III, with increasingly granular risk categories.
For depositors trying to understand bank safety, risk-weighted assets matter because they determine whether capital ratios are genuinely strong or artificially inflated. A bank might show a high Tier 1 ratio simply because it holds very safe assets. Conversely, a bank with aggressive lending in high-risk categories could have a lower effective capital cushion than its headline ratio suggests. When comparing banks on BankHealthData, consider that institutions with similar Tier 1 ratios may have very different underlying risk profiles depending on their loan portfolios.
