What Is a Polycrisis, and Why It Matters for Supply Chains

Intro to Polycrisis: what it is, why it matters now, and the one change operators should make this quarter.

Supply chains were built for variable demand and occasional shocks. They were not built for several shocks interacting at once, amplifying each other across logistics, finance, data, the geopolitical environment and reputation. That interaction effect is the polycrisis. It is not a headline, it’s a mechanism. Understanding the mechanism is how operators cut decision time, protect service, and avoid paying twice – once in disruption, and again in over-correction.

Big idea: stop cataloguing incidents; model how stresses become triggers and propagate as crises.

Three quick takeaways

• Polycrisis = interaction, not accumulation. Five small problems that reinforce each other can be worse than one big one.
• Model the flow, not just the event. Map how a stress turns into a trigger and travels via propagation pathways to become a crisis.
• Prioritise where you can act with effect. Focus on high-exposure × controllability (E×C) items and reduce decision latency.

What we mean by “polycrisis”

A polycrisis is a system-level problem where multiple stresses interact, creating feedback loops and nonlinear outcomes. Think of drought pressuring hydropower → power rationing hits smelters → metal availability tightens → component prices rise → project deferrals spread. Meanwhile, a cyber incident forces manual workarounds that slow already constrained flows. None of these on its own is novel. The compounding interaction is.

Classic risk lists treat these as separate rows. Operators experience them as connected pathways.

The operator’s pitfall: perfecting the incident list

Most teams do two things well: register incidents and assign owners. The gap is what happens between incidents, how signals travel across physical, informational, financial and reputational channels. That’s where delay, duplication and “fix-then-re-fix” costs come from.

Two symptoms to watch for:

1. “Whack-a-mole” fixes: the same problem reappears one hop downstream (e.g., port congestion solved by premium air freight that quietly blows the budget).
2. Powerpoint resilience: heat maps and qualitative scores that don’t change decisions or sequencing.

A better frame: STC and propagation pathways

Stresses → Triggers → Crises (STC).

• Stresses are background pressures that raise the probability or consequence of failure (e.g., supplier concentration, shallow buffers, regulatory drift).
• Triggers are discrete events or thresholds that “flip the system” (e.g., a water level crossing, a cyber breach, a credit downgrade).
• Crises are the escalated operational states that management actually feels, like missed OTIF, margin compression, and reputational damage.

Propagation pathways explain how trouble travels:

• Physical: capacity, topology, chokepoints, mode shifts.
• Informational: data quality, cyber events, forecasting errors, signal delays.
• Financial: liquidity, FX, rates, counterparties, insurance.
• Reputational/Political: media cycles, stakeholder pressure, policy intervention.

When you make these pathways visible, you can see which stresses prime which triggers, and which levers can interrupt the flow early.

Why this matters now

• Tighter cycles, tighter margins compress diagnosis time and remove slack.
• Coupled systems raise the blast radius, meaning errors propagate faster and are visible to stakeholders in real time.

The penalty for slow or mis-sequenced action is rising. The upside for firms that can sense, model and intervene is also rising, meaning better, steadier service, lower cost-to-serve variability, and faster strategic pivots.

Mini-case: one shock, three pathways

Imagine a regional port blackout halts reefer power for 18 hours.

• Physical: emergency re-plugs and diversions consume scarce yard labour. Missed stack windows push boxes to the next cut-off. Retail DCs receive late or out-of-sequence loads.
• Informational: manual rebooking creates duplicate IDs. ETA/temperature telemetry gaps trigger false spoilage alerts.
• Financial: expedited trucking and penalties hit the P&L. A key distributor delays payment: citing shortage claims. Treasury lifts the weekly cash buffer, squeezing other projects.

If you only “close the incident” at the terminal, you still absorb the hidden costs in planning, cash and customer trust. If you model the pathways, you can insert earlier switches: pre-authorised alternate plug points, a clean telemetry fallback, and a credit-control trigger for at-risk partners.

The one change to make this quarter

Adopt a living risk map that connects STC to pathways and E×C. In practice:

1. Run a 90-minute STC session. Name 5–7 material stresses; state explicit triggers (real measurable thresholds). Define the crisis states that matter to you (service, cost, cash, reputation).
2. Sketch the propagation. For the top two triggers, trace one hop per pathway (physical, informational, financial, reputational). Boxes and arrows are enough.
3. Score E×C at a glance. Exposure (how big/how often) × Controllability (do we have a lever we can pull?). Use a 1–3 scale to start.
4. Create a short “switch list.” For the top three E×C items, write the pre-authorised moves you can take within 48 hours (e.g., capacity swaps, data fallbacks, comms lines, credit holds).
5. Set cadence. Revisit monthly. Archive stale items. Promote emergent stresses. Adjust triggers as conditions change.

This is not a multi-month transformation. It is a discipline that turns scattered knowledge into faster, better-sequenced action.

What this means for operators

• Model the flow. Trace stress → trigger → crisis across each pathway.
• Fund switches. Pre-authorise alternates, don’t only add buffers.
• Track latency. Measure signal → decision → action time, and compress quarterly.
• Standardise language. Use STC, pathways and E×C across teams.
