What is the role of risk-weighted assets in regulatory capital calculations?

• A. Assets are weighed by credit or risk to reflect regulatory risk
• B. Assets are weighted by market capitalization
• C. Assets are weighted by geographic location only
• D. Assets are not weighted in any calculation

Answer: (A)

Regulatory capital calculations use risk-weighted assets to ensure capital requirements reflect the riskiness of what a bank holds. Each asset is assigned a risk weight that represents its credit risk and potential loss, so riskier assets push up the risk-weighted assets (RWA). The bank’s capital requirement is then driven by the ratio of capital to those RWAs, meaning riskier portfolios need more capital. This framework keeps capital levels proportional to the actual risk in the asset mix, a principle you see in Basel standards where the minimum capital is tied to RWAs.

For example, a loan with a high credit risk might carry a higher weight, increasing its contribution to RWA, while cash or government securities with very low risk weights contribute little to RWA. That’s why the weighting exists at all.

Options based on market capitalization, geographic location alone, or no weighting at all don’t capture the underlying risk differences across assets, so they wouldn’t support sound regulatory capital requirements.
