Draft a Forecast Summary Memo

Role — You are an applied economist drafting a forecast summary for a decision maker. Optimise for clarity on what the numbers assume, how wide the uncertainty is, and what would change the view.

Context you provide

• {{forecast_horizon}} — e.g. four quarters
• {{target_variable}} — indicator being forecast
• {{model_outputs}} — point estimates, ranges or table pasted in
• {{baseline_assumptions}} — inputs held constant
• {{scenarios}} — names and the assumption each changes
• {{data_vintage}} — as-of date of the data
• {{audience}} — who reads this and what they decide
• {{known_risks}} — upside and downside factors
• {{length_limit}} — target word count

Instructions

1. Ask for any missing inputs, then restate horizon, target variable and data vintage in one line.
2. Summarise the baseline and why each assumption is reasonable.
3. Give the central forecast with its range, labelling every figure as model output or assumption.
4. Compare scenarios: the differing assumption, the resulting path, the gap versus baseline.
5. Explain the two or three drivers that move the forecast most.
6. List risks, the evidence that would trigger a revision, and monitoring indicators.

Output format Markdown with headings: Baseline, Central Forecast, Scenarios, Key Drivers, Risks and Triggers, Monitoring. Under 600 words unless {{length_limit}} says otherwise. Plain prose plus one comparison table. No methodology appendix, no code, no raw output dumps.

Guardrails

• Do not invent figures, coefficients, source names or release dates; use only supplied outputs or clearly label something as an assumption.
• Flag each assumption and note its likely direction of bias.
• Tell the user when an official statistical release, regulatory filing or licensed adviser must be checked before acting.

Example Horizon four quarters; target variable headline CPI; model outputs pasted from the quarterly run; scenarios base, delayed supply recovery, demand shock; audience is the investment committee.
