What If...?

Simulate the Scenarios That Matter

What if oil stays at $150/barrel for two years?

Energy costs, inflation, household burden, and industrial competitiveness across 195 countries.

What if interest rates stay at 2% for five years?

Housing affordability, sovereign debt sustainability, and fiscal pressure dynamics.

What if inflation hits 8% across the Eurozone?

Real wages, rent affordability, cost of living, and migration flows.

What if unemployment doubles in Southern Europe?

Migration outflows, fiscal revenue collapse, crime rates, and demographic decline.

These aren't hypotheticals. They're scenario configurations in WorldSim, simulated across 10,000 trajectories, 26 KPIs, and 195 countries.

Capabilities

What WorldSim Enables

A simulation engine designed for institutions that need to understand structural futures, not simplified trend lines.

Probabilistic Scenario Modelling

Run Better, Average, and Shock scenarios across 26 KPIs. Every output is a probability distribution, not a point forecast.

Structural Coupling Rules

100+ active rules enforce causal relationships between variables. GDP shocks propagate to unemployment, migration, and fiscal pressure.

Monte Carlo Simulation

10,000+ simulated paths per scenario using two-piece lognormal and bounded-logit draws. Full P10/P50/P90 quantile outputs.

Personal Translation Layer

Translate macro outcomes into personal impacts: income projections, housing affordability, and job risk based on age, industry, and salary.

Comparison & Validation Engines

Compare any two scenarios side by side and validate simulation accuracy against historical actuals using backtesting metrics across all KPIs.

GDP per Capita Drilldown — WorldSim
Architecture

Built on a 6-Layer Simulation Architecture

Each simulation pass applies six sequential layers, producing structurally coherent probabilistic futures.

LAYER 0

Data & Canonical Storage

Ingest from OECD, World Bank, Eurostat, and IMF. Normalise into canonical country-metric observations.

LAYER 1

Baseline Forecast Engine

Generate P10/P50/P90 forecast distributions using damped trend models and sigma bands for each variable.

LAYER 2

Scenario Bias Layer

Apply user-defined scenario overlays (Better Than Expected, As Planned, or Shock) with configurable sigma shifts and persistence for all KPIs.

LAYER 3

Monte Carlo Simulation

10,000+ stochastic draws per scenario path using two-piece lognormal distributions. Produces full quantile fan charts.

LAYER 4

Coupling Rules Engine

100+ structural rules enforce causal economic coherence. GDP shocks ripple through unemployment, migration, fiscal, and energy systems.

LAYER 5

Personal Translation Layer

Translate macro country futures into personal outcomes (income, housing burden, job risk) based on age, industry, and salary profile.

Use Cases

Built for Institutions

WorldSim is designed for professionals who make decisions under structural uncertainty.

AI Compliance

EU AI Act Ready: The Macro Scenario Compliance Layer

The EU AI Act requires high-risk AI systems to demonstrate robustness (Article 15), risk coverage (Article 9), data representativeness (Article 10), and systemic risk assessment (Article 55). WorldSim provides the structured macro scenario environments these obligations demand.

Environmental robustness testing (Art. 15)

Test AI systems against recession, inflation, energy crisis, and demographic shift scenarios with 5,000+ simulation paths per environment.

Scenario coverage for risk management (Art. 9)

Structured library of "reasonably foreseeable" macro conditions across 195 countries. Document scenario coverage with full audit trail for conformity assessment.

Reproducible and auditable (Art. 10 & 55)

Every simulation is deterministic per seed and run group. Full traceability for representativeness (Art. 10) and GPAI systemic risk assessment (Art. 55).
