Question 1(a): Two Key Drivers of Credit Risk and Their Relationship to
Probability of Default (PD)
(5 Marks)
Credit risk refers to the possibility that a borrower or counterparty will be unable to meet
their financial obligations, such as repaying a loan’s principal and interest as agreed.
One of the core measures used to assess credit risk is the Probability of Default
(PD)—which estimates the likelihood that a borrower will default on a debt obligation
within a defined time period, typically one year. Two key elements that strongly
influence credit risk and directly affect PD are the financial health of the borrower and
the broader macroeconomic context in which they operate.
1. Financial Health of the Borrower (Credit Profile)
The individual or business's financial stability plays a foundational role in determining
how likely they are to default. Lenders often assess this through quantitative indicators
such as solvency, liquidity, profitability, and leverage ratios. A financially stable
borrower—one who consistently generates sufficient cash flow, maintains manageable
debt levels, and exhibits strong profitability—is typically assigned a lower PD, indicating
reduced credit risk.
Key evaluation tools include:
Debt-to-equity ratio (measuring leverage),
Interest coverage ratio (indicating how well earnings cover interest payments),
Cash flow analysis, and
Credit scoring models such as the Altman Z-score or internal bank models
used under the Internal Ratings-Based (IRB) approach of Basel II/III.
A borrower with strong financial fundamentals is less vulnerable to adverse shocks and
thus less likely to default, lowering their associated PD.
