Economic Scenarios

Baseline forecasts and alternative scenarios for more than 100 countries/jurisdictions, updated monthly, for evaluating shocks and differing assumptions.

Moody's Analytics scenarios are the foundation of stress testing and "what if?" analysis for risk management, compliance and strategic planning needs. Clients from a broad range of industries can use our scenarios to test the impact of shocks and differing economic assumptions on their businesses and portfolios. Scenarios are produced and maintained by a team of more than 80 experienced economists.


Our scenario-driven approach to forecasting begins with our baseline forecast. We define this as the “most likely outcome” based on current conditions and our view of where the economy is headed. We then develop the basic outlines of our alternative scenarios by running multiple simulations to develop a probability distribution of economic outcomes. From this, we produce fully-fledged economic scenarios:

  • S1 - Stronger Near-Term Rebound
  • BL - Baseline Forecast
  • S2 - Slower Near-Term Recovery
  • S3 - Moderate Recession
  • S4 - Protracted Slump
  • S5 - Below-Trend Long-Term Growth
  • S6 - Stagflation
  • S7 - Next-Cycle Recession (US Only)
  • S8 - Low Oil Price
  • CS - Constant Severity (Independent of current business cycle)
  • CBL - Consensus Baseline (US Only)

Some of scenarios are cyclical, extending only through the current business cycle, with no change in the economy’s long-run growth rate. Others are longer term, with different long-run growth rates compared to the baseline.  We provide an economic narrative for each scenario, explaining what would cause the change in the outlook relative to the baseline. That story changes over time as underlying economic conditions change. Our approach consists of:

  • Dynamic systems of equations representing the components of aggregate demand and supply.
  • Quarterly or monthly re-estimation of equations for model robustness and forecasting accuracy.
  • Time-series and panel-data econometric techniques brought forward into the estimation process.
  • Monte Carlo simulations to generate deviations from our median/baseline forecast and to produce empirical probability distributions.
