Guarantees on loans and bonds were assigned a credit conversion factor of 100% under Basel I. This means that these types of off-balance sheet exposures were considered to have the same credit risk as on-balance sheet exposures. Guarantees on loans and bonds are commitments made by a bank to cover the losses of a borrower in case of their default. Given the high risk associated with these commitments, they were assigned the highest credit conversion factor. This ensured that banks held sufficient capital against these exposures, thereby promoting financial stability.

Choice A is incorrect. According to Basel I, loan commitments with an original maturity of 6 months were assigned a credit conversion factor of 20%, not 100%. This means that only 20% of the off-balance sheet exposure would be converted into an on-balance sheet equivalent.

Choice B is incorrect. Loan commitments with an original maturity of one year were also assigned a credit conversion factor lower than 100% under Basel I. The higher the maturity, the higher the risk and hence, a higher credit conversion factor but it was still less than 100%.

Choice D is incorrect. Standby letters of credit related to trade transactions were not assigned a credit conversion factor of 100%. These are considered less risky compared to guarantees on loans and bonds because they are contingent upon certain events or conditions being met.

Things to Remember

• Basel I was the first international banking regulation that aimed to ensure banks maintained adequate capital reserves to cover their risks.
• Credit conversion factors were used to convert off-balance sheet exposures to on-balance sheet equivalents based on their credit risk.
• Guarantees on loans and bonds were considered high-risk off-balance sheet exposures and assigned a credit conversion factor of 100% under Basel I.
• Loan commitments with different original maturities were assigned varying credit conversion factors, with shorter maturities typically having lower factors.
• Standby letters of credit were also off-balance sheet exposures but were considered less risky compared to guarantees on loans and bonds.
