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.

Scenario under test: AI data-center capex air-pocket transmits to power & private credit

Desk thesis: An AI-infrastructure spending pause would transmit out of tech and into power, REITs and private credit before consensus re-rates the productivity premium.

Desk probability at run time: 15% — see the scenario register for the current number and model card.

What the simulation surfaced — probes for the desk

A top-5 hyperscaler cuts data-center capex 20%+ year-on-year
The AI-infrastructure credit basket widens ~150bp, re-rating private credit
Thin private-credit liquidity transmits marks into pension and insurer books
Doubts over GPU useful life compress the embedded AI productivity premium
Long-horizon owners reassess AI-infrastructure exposure as the tripwire nears

From the simulation record

The simulation places the AI data-center capex air-pocket at roughly a 17% probability (up from 15%), driven by thin private-credit liquidity, the prospect of a top-5 hyperscaler cutting capital expenditure by 20% or more year-on-year, and growing doubts about effective GPU useful life. As hyperscaler capex is trimmed and the AI-infrastructure credit basket widens (a ~150bp move flagged as a tripwire), private-credit demand re-rates and marks fall - flowing through to the private-credit books of pensions and insurers as impairments.

Among the simulated long-horizon owners, sovereign wealth funds and public pensions re-examine their exposure as the tripwire is approached, insurers tighten risk management on AI-infrastructure credit, and endowments rotate toward technologies with longer-run growth potential rather than the most volatile data-center exposure. The recurring blind spot the run surfaces is the reassessment of the 'AI productivity premium' embedded in long-run return assumptions - and the risk that persistent air-pocket conditions erode confidence in future capital inflows to AI infrastructure.

Scenario under test: Stock-bond correlation regime break — the 60/40 / LDI hedge fails

Desk thesis: If bonds stop hedging equities, the 60/40 and LDI hedges that anchor most policy portfolios quietly stop working.

Desk probability at run time: 36% — see the scenario register for the current number and model card.

What the simulation surfaced — probes for the desk

60/40 and LDI hedges stop working once bonds no longer hedge equities
Long-duration owners rotate to alternatives, PE and real assets, raising cash buffers
Inflation surprises (CPI ~3.95% in the run) act as the regime trigger point
Frequent rebalancing raises transaction costs and can destroy returns
Counter-case: markets self-correct and stock-bond correlation re-normalizes

From the simulation record

In the simulated correlation-break regime, long-duration owners (sovereign funds, public pensions) reconstructed portfolios around the judgment that 60/40 and LDI hedging had already failed as signals, rotating toward alternatives, private equity and real assets while raising cash buffers against a liquidity squeeze.

Dissent was material: one camp argued markets self-correct and correlation re-normalizes, while skeptics of dynamic allocation warned that frequent rebalancing raises transaction costs and can destroy returns — with inflation surprises (CPI YoY 3.95% in the run) and geopolitical shocks identified as the trigger points that would force the issue.

What the simulation surfaced — probes for the desk

Water and food-system stress: sovereign stability implications
Import-dependent sovereigns face compounding fiscal and social pressure as food and water prices rise; simulation data points to heat stress → hydropower disruption → food inflation as the primary transmission chain, with export-restriction discussions among major producers amplifying cross-border contagion risk.

From the simulation record

Water and food-system stress poses a growing threat to sovereign stability, particularly for import-dependent economies. Simulation rounds show three converging pressures: fiscal strain from rising food and water prices, escalating social unrest in drought-affected regions, and tightening international relations as major grain exporters discuss export restrictions.

Governments face a difficult trade-off — price controls and subsidies can cushion near-term discontent but deepen fiscal deficits, while inaction risks protests escalating into political instability. Simulation data highlights that heat stress reducing hydropower output and driving cost-push food inflation is the key transmission mechanism linking climate shocks to sovereign balance sheets.

On the international side, export-restriction chatter among major producers signals a fragmentation risk to global supply chains. A confirmed export ban by a major grain exporter would rapidly propagate stress to highly import-dependent sovereigns, many of which are already fiscally constrained.

The simulation also identifies an adaptive opportunity: countries investing early in sustainable agriculture and water management show meaningfully better resilience outcomes, suggesting that capital allocation toward water infrastructure and climate-adapted agriculture is not just an ESG consideration but a sovereign-risk management imperative.

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: Sovereign-debt sustainability & fiscal dominance

Desk thesis: Rising debt loads meeting still-high real rates push toward financial repression — quietly degrading the 'risk-free' rate permanent capital relies on.

Desk probability at run time: 34% — see the scenario register for the current number and model card.

What the simulation surfaced — probes for the desk

Are weak G7 long-bond auctions (low bid-to-cover, widening tails) becoming a leading trigger for sovereign-debt-sustainability repricing rather than a lagging symptom?
Is the risk-free rate ceasing to be a clean source of return for permanent capital where policy slides into financial repression or yield-curve control?
Does rising long-end yields against a rising debt burden read as a real regime signal for long-horizon allocators, or as noise the desk should discount?
How are sovereign wealth funds and public pensions repositioning duration, inflation linkers and real assets as fiscal dominance suppresses real returns on government debt?
Is cross-owner coordination and information-sharing among the largest asset owners rising as a response to sovereign-debt stress, and does that shift market dynamics?

From the simulation record

In the simulated environment, the relationship between sovereign-debt sustainability and fiscal dominance became the binding constraint on long-horizon capital owners — sovereign wealth funds, public pensions, insurers and endowments. As fiscal-dominance policy tightened, the durability of sovereign debt drove investment decisions, and allocators were forced to respond flexibly within a shifting and uncertain policy regime.

Several market signals surfaced for the desk to investigate. The simulation flagged rising long-end yields against a rising debt burden as a weak signal; it noted that the risk-free rate may no longer be a clean source of return for permanent capital where policy produces financial repression or yield-curve control, suppressing real returns; and it identified poor G7 long-bond auctions as a potential trigger for sovereign-debt-sustainability concerns. In response, simulated owners leaned toward safer asset channels and toward greater information-sharing and cooperation with peers.

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).

Scenario under test: Transition-mineral & grid-interconnection bottleneck caps electrification / AI

Desk thesis: Copper and the grid interconnection queue — not chips or capital — may be the binding constraint on both electrification and AI.

Desk probability at run time: 43% — see the scenario register for the current number and model card.

What the simulation surfaced — probes for the desk

AI development faces a fresh constraint set once electrification hits the grid-interconnection ceiling — compute scales with available power, not demand
Tight power supply and the operating limits it imposes on AI deployment, with a hyperscaler deferring builds-on-power as the tripwire to watch

From the simulation record

In the simulated world, electrification runs into a hard ceiling well before chips or capital do: grid interconnection is the bottleneck. As the run put it, “Electrification is capped by a grid interconnection bottleneck,” and from there “power becomes the binding constraint on electrification” — forcing the simulated capital owners to treat power availability and grid headroom, not equipment or financing, as the first input to every allocation decision.

The same constraint propagates straight into AI. With “power becomes the binding constraint on AI,” high-intensity compute is throttled by what the grid can deliver, and the agents watch for a clean tripwire: “a hyperscaler defers builds on power.” When a hyperscaler slips data-center construction because of energy rather than demand, the simulation treats it as confirmation that the interconnection queue — not the order book — is now setting the pace of the AI build-out.

Critical minerals act as the early-warning layer. Elevated copper reads as “a weak signal for interconnection queues,” so the simulated owners track transition-mineral prices as a leading proxy for grid stress and supply-chain fragility rather than as a stand-alone commodity bet. Rising copper, in this frame, is a flag on the build-out before it shows up in megawatts.

Policy is the wildcard that can reorder the whole transition. “Energy-security policy reorders the transition” repeats across every section: governments re-prioritizing security can reshuffle which projects clear, leaving allocators more cautious on resource and power planning. The agents diverge in response — some lean harder into renewables to relieve the power constraint, others defer commitments until the policy path clears — and the desk flags the resulting probes: power-supply instability stretching project timelines, a possible reshuffle of market structure as the bottleneck persists, lagging interconnection technology capping new applications, and policy uncertainty itself as a drag on stable returns.
