Credit Conversion Factor
Also known as CCF, Conversion Factor
A credit conversion factor (CCF) is the percentage that turns an off-balance-sheet exposure, such as an unused loan commitment or a standby letter of credit, into an on-balance-sheet credit equivalent amount. The credit equivalent amount is then risk-weighted like a loan to the same borrower and added to risk-weighted assets.
How a credit conversion factor is applied
Under the US standardized approach (12 CFR 217.33, 3.33 and 324.33) the CCF depends on the type of exposure. 0% applies to commitments the bank can cancel unconditionally at any time, such as most credit card lines. 20% applies to commitments with an original maturity of one year or less and to short-term, self-liquidating trade letters of credit. 50% applies to commitments with an original maturity of more than one year and to transaction-related contingent items such as performance bonds and performance standby letters of credit. 100% applies to guarantees, financial standby letters of credit, repo-style transactions, credit-enhancing representations and warranties, and forward agreements. Banks report the amounts, factors and resulting credit equivalents on Call Report Schedule RC-R, Part II.
- Identify the off-balance-sheet exposure and its type (commitment, letter of credit, guarantee).
- Look up its credit conversion factor under the capital rule (0%, 20%, 50% or 100%).
- Multiply the exposure by the CCF to get the credit equivalent amount.
- Multiply the credit equivalent amount by the risk weight of the counterparty and add the result to risk-weighted assets.
Worked example
Source: FFIEC Call Report Schedule RC-L, quarter ended June 30, 2026: financial standby letters of credit (RCFD3819), performance standby letters of credit (RCFD3821) and commercial and similar letters of credit (RCFD3411). The bank's own conversion, net of participations and collateral, is on Schedule RC-R, Part II.
Why does the credit conversion factor matter?
A loan commitment or a guarantee carries credit risk before any money moves: the borrower draws on the line, or the bank pays out on the guarantee, typically when the counterparty is in trouble. Without a conversion factor these exposures would need no capital. CCFs set how much of each is treated as if it were already a loan, so they change the capital cost of selling credit lines and letters of credit.
How do you interpret the credit conversion factor?
A bank with large unused commitments can carry more risk-weighted assets than its loan book suggests. Read Schedule RC-L for the size of unused commitments and letters of credit, and Schedule RC-R, Part II for how much risk-weighted assets they add. Unconditionally cancelable lines carry a 0% CCF, so a bank with big credit card lines shows little capital charge for them; the leverage ratio ignores most of these exposures, while the supplementary leverage ratio at the largest banks counts them.
Credit conversion factors by exposure type
| Range | Label | Interpretation |
|---|---|---|
| 0% | Unconditionally cancelable | Commitments the bank can cancel at any time without notice, such as most credit card lines. |
| 20% | Short-term | Commitments with an original maturity of one year or less; short-term trade letters of credit. |
| 50% | Longer-term or performance | Commitments over one year; performance bonds and performance standby letters of credit. |
| 100% | Direct credit substitute | Guarantees, financial standby letters of credit, repo-style transactions and forward agreements. |
Frequently asked
What is a credit conversion factor?
A credit conversion factor is the percentage of an off-balance-sheet exposure that the capital rules treat as an on-balance-sheet loan. It turns commitments, letters of credit and guarantees into credit equivalent amounts for risk-weighted assets.
What CCF applies to an unused loan commitment?
Under the US standardized approach, 20% if the commitment's original maturity is one year or less, 50% if it is longer, and 0% if the bank can cancel it unconditionally at any time.
Where do banks report credit conversion factors?
On Call Report Schedule RC-R, Part II, which lists each type of off-balance-sheet item with its face amount, conversion factor, credit equivalent amount and risk-weight allocation.
Do US and Basel credit conversion factors match?
Mostly, for the standardized approach in force in the US. The revised Basel III standard changes some factors, including a 10% CCF for unconditionally cancelable commitments, and US rules adopt those changes only if and when a final rule says so.
