What Is the Standardised Approach?
A standardised approach is a regulator-prescribed method banks use to calculate capital requirements without relying primarily on their own internal risk models. The term appears across Basel capital rules, including credit risk, counterparty credit risk, market risk, and operational risk.
The spelling “standardised” is commonly used in Basel and many non-U.S. regulatory materials. In U.S. materials, the same concept is often spelled “standardized.”
Key Takeaways
- A standardised approach uses regulator-defined rules rather than bank-specific internal models.
- It improves comparability across banks.
- It may be less risk-sensitive than advanced internal model approaches.
- Basel III reforms strengthened standardised approaches and linked them to the output floor.
- The exact calculation depends on the risk type being measured.
How It Works
Under a standardised approach, regulators define the categories, inputs, risk weights, formulas, or measurement rules used to calculate capital. A bank applies those rules to its exposures instead of fully substituting its own model estimates.
For example, a credit exposure may receive a prescribed risk weight based on exposure type, counterparty type, rating, collateral, or other regulatory criteria. The result feeds into risk-weighted assets and therefore into the capital ratio denominator.
Where the Term Appears
Area | How the approach is used |
|---|---|
Credit risk | Uses regulator-defined risk weights and exposure categories. |
Counterparty credit risk | Measures derivative and financing exposure under prescribed rules. |
Market risk | Provides a non-internal-model route for trading-book capital. |
Operational risk | Uses a formulaic framework rather than legacy internal loss distribution models. |
Balance Sheet Tradeoffs
Standardised approaches make capital ratios easier to compare because the rules are less dependent on each bank's own modeling choices. That can help regulators, investors, and counterparties judge capital strength across institutions.
The tradeoff is that standardised approaches can be blunt. A simple risk weight may not capture every detail of a bank's underwriting, collateral, hedging, or portfolio quality. Internal models can be more risk-sensitive, but they can also create complexity and variability.
The term can be confusing because there is no single universal standardised approach. The credit-risk standardised approach is not the same as the operational-risk standardised approach or the counterparty-credit-risk standardised approach. The shared idea is prescribed methodology, not one common formula.
Standardised approaches also serve as a common language for supervisors. Even when a bank uses internal models, regulators can compare the model result with a standardised baseline to see whether the modeled capital outcome looks unusually low.
That baseline role became more important after the global financial crisis, when Basel reforms focused on reducing excessive variability in risk-weighted assets.
The Bottom Line
A standardised approach is a rule-based way to calculate bank capital requirements. It is central to Basel comparability and to the output floor, which limits how far internal models can reduce risk-weighted assets below standardised results.
