The Simulation Desk · agent-based scenario simulation · 2026-06-21
We stress-tested one scenario from the desk’s register with an ensemble of interacting simulated actors — institutions, intermediaries, policymakers and traders — and let them argue, trade and react over 4 rounds. What follows is what the simulation surfaced for the desk to investigate. It is calibration-gated: it carries 0 percentage points on every published probability (cap 5pp, Day 18). Probes, not predictions.
Scenario under test: Chokepoint concentration as a standing factor (Hormuz + Taiwan + Malacca + Panama)
Desk thesis: Too much of the world's energy and container flow now hinges on a handful of contested straits at once — a standing, not episodic, exposure.
Desk probability at run time: 53% — see the scenario register for the current number and model card.
What the simulation surfaced — probes for the desk
- Whether the simultaneous concentration of the Hormuz, Taiwan, Malacca and Panama chokepoints behaves as a standing structural exposure rather than a series of one-off shocks for long-horizon owners.
- How persistent chokepoint disruption transmits into freight costs, marine-insurance rates and inflation — the run shows a Malacca event touching ~20% of LNG flow and a Hormuz event ~20% of oil flow, with Brent near $102.75.
- How the simulated actors — governments, businesses, insurers, academics and consumers — adapt: route diversification, friend-shoring, insurance repricing and rotation toward less chokepoint-exposed technology and renewables.
- Whether markets historically absorb chokepoint shocks through alternative routing — making flexibility and adaptability, not avoidance, the central prescription, and over-reaction a risk to emerging-market opportunity.
From the simulation record
In the simulation, the simultaneous concentration of the Hormuz, Taiwan, Malacca and Panama chokepoints behaves as a standing structural exposure rather than a series of one-off shocks. As disruptions persist, simulated freight costs and marine-insurance rates rise together, lifting operating costs and inflationary pressure; a Malacca disruption is shown affecting roughly 20% of LNG flow and a Hormuz event roughly 20% of oil flow, with Brent trading near $102.75 in the run.
Across the simulated actors - governments, businesses and investors, insurers, academics and consumers - the dominant response is adaptation: diversifying shipping routes, weighing 'friend-shoring', repricing insurance, and rotating toward technology and renewable-energy sectors seen as less chokepoint-exposed. A notable counter-current argues the market has historically absorbed chokepoint shocks through alternative routing, so overreacting could forfeit opportunities in emerging markets - leaving flexibility and adaptability, not avoidance, as the run's central prescription for long-horizon owners.
What this is — and is not
These are research prompts surfaced by a simulation, not facts and not published probabilities. Anything that survives the desk’s source-gated investigation shows up in the scenario’s model card with named sources; the rest is discarded.
