What it means
In finance and banking, institutions must hold a certain amount of capital as a safety buffer against potential losses from loans and investments. While large banks often create bespoke, highly sophisticated computer models to calculate these risks, smaller or less complex institutions use the Standardised Approach.
This framework relies on external ratings from recognised credit agencies or predetermined risk weights assigned directly by regulators. For non-finance managers, understanding this concept matters because it dictates how much money banks must set aside, which directly influences the cost and availability of business credit.
When rules change, the pricing of loans can shift noticeably. In practice, applying this approach is straightforward.
If a bank lends money to a retail customer to buy a home, the regulator assigns a specific risk weight, such as 35 percent. The bank then calculates its required capital based on that fixed percentage.
By using uniform rules across the board, regulators ensure that different institutions can be compared easily and fairly. It removes guesswork and prevents individual firms from underestimating their potential risks during economic downturns.
Think of it like speed limits on public roads. Instead of letting every driver decide how fast is safe based on their own car's custom engineering, the government sets clear, fixed limits for everyone to follow.
In practice
Real-world examples
Example 1
A high street bank lends $1,000,000 to a small manufacturing firm with an official credit rating of BBB. Under the Standardised Approach, the bank applies the risk weight that the regulator assigns to that rating, which is often 100%. Risk-weighted assets are therefore $1,000,000, and at an 8% capital ratio the bank must hold $80,000 against the loan. If the borrower's rating were upgraded, the lender could apply a lower risk weight and free up some of that capital for other lending.
Example 2
A regional lender provides a commercial mortgage of $500,000 for a retail shop. Where the rules assign a fixed 50% risk weight to this type of property loan, risk-weighted assets are $250,000. At an 8% capital ratio, the bank needs $20,000 of capital, which simplifies its planning and pricing. The bank does not need its own statistical model because the regulator has already set the percentage, and that makes the number easy to audit.
Example 3
A fintech lender offers unsecured consumer loans totalling $2,000,000. If the rules require a 150% risk weight for these higher risk borrowings, risk-weighted assets are $3,000,000. At an 8% ratio, the lender must hold $240,000 of capital, a much larger cushion than for secured lending. The lender must therefore charge higher interest on these loans to earn an acceptable return on the extra capital it ties up.

Formula
Calculation
Risk-Weighted Assets (RWA) = Exposure Amount x Regulatory Risk Weight
Example:
Loan Amount = $200,000
Regulatory Risk Weight for retail SME loan = 75 percent (0.75)
RWA = 200,000 x 0.75 = $150,000
Minimum Capital Required (e.g., 8 percent ratio) = 150,000 x 0.08 = $12,000.Case study
Seen in the real world
This is a fictional, illustrative scenario. Oakwood Bank, a growing regional lender, wanted to expand its small business lending portfolio without investing millions in complex risk-modelling software. The management team decided to adopt the Standardised Approach for all new commercial loan evaluations. When Oakwood issued a $5,000,000 loan package to a local logistics fleet, they checked the regulatory rulebook rather than running proprietary simulations.
The rules specified a 100% risk weight for unrated corporate exposures. Oakwood multiplied the $5,000,000 exposure by 100% to find a risk-weighted asset total of $5,000,000. Applying their required 10% capital ratio, Oakwood immediately set aside $500,000 in capital reserves. This transparent method allowed Oakwood Bank to secure regulatory approval quickly, price their loans accurately, and expand their lending operations safely within statutory limits.
The same logic helped Oakwood explain its pricing to borrowers. Because the $500,000 of capital has a cost, the bank could show that each $1,000,000 of lending ties up $100,000 of capital, and it built that cost into the interest rate it quoted to the logistics firm. Oakwood's board also liked that the regulator's published weights allowed it to test several lending scenarios quickly, such as what would happen to capital if the loan book grew by 20%.
Watch out
Common mistakes
- Assuming the Standardised Approach results in lower capital requirements than internal models.
- Failing to update external credit ratings when a borrower's financial health changes.
- Treating all loans within a broad category as identical without checking specific qualifying criteria.
