Meet regulatory requirements, evaluate the impact of shocks and develop strategic plans.
At Moody's Analytics, our team of more than 80 economists employ a holistic and fundamental approach to stress-testing. We focus on the underlying drivers of portfolio performance and link these drivers to alternative scenarios based on a range of possible outcomes given the current business cycle.
Based on stress testing and scenario analyses, management can take strategic actions to mitigate risk and enhance economic return, such as adjusting economic capital levels, adjusting portfolio mix and raising/lowering lending standards.By linking performance drivers to global and local economic activity, our stress-testing and scenario analysis approach generates more realistic results to assess portfolio performance due to sovereign defaults, energy crises, and even of more factors. We provide stress-testing and loss forecasting capabilities for all portfolio types.
We also incorporate and link off-the-shelf and custom/bespoke scenarios across clients' portfolios for more realistic stress tests. Stressed scenarios are developed in line with our clients' unique regional and industry exposures. Our theoretical approach and equation outcomes are transparent and fully documented. When necessary further calibration on the models is performed to meet the clients' needs. Custom solutions include:
- Credit Portfolio Risk Optimization
Beyond regulatory driven exercises, many of our clients leverage our expertise for portfolio risk optimization projects and strategic planning. We help investment strategy and risk teams to stress portfolios under different custom scenarios in order to provide investment criteria recommendations in line with the client risk appetite and investment objectives. These exercises are particularly popular among our asset management and insurance clients who may be required to divest under their credit investment policy should certain shocks affect the ratings of their assets.
- Financial Metrics/Market Risk
We have developed an integrated framework, where the background macroeconomic scenarios are fully calibrated to reflect our alternative assumptions on the relevant risks to the Moody's Analytics baseline forecast. Key macroeconomic series are then correlated to the relevant financial and credit metrics to produce the output results (e.g., yield and swap rate curves, risk-free rates, CDS spreads, rating migration, equity indexes, etc.).
- Rating Transitions
We can stress-test rating migrations for any portfolio of corporate (financials and non-financials) and sovereign bonds. The migration information can be provided by internal rating models and/or using Moody's transition data. We use dynamic panel data models to capture the behavior of transition matrices over time. This exercise allows us to quantify the sensitivity of migrations to changes in macro and financial series.
- Economic Scenario Generator Engine for Solvency II
Our clients can benefit from our Economic Scenario Generator service in two ways; by being delivered custom outputs from our in-house model or by implementing our Economic Scenario Generator engine within their existing platforms and therefore being in full control of the process.
