Leaders should plan for colliding risks, not isolated crises. Here’s why

Ask chief executives what keeps them awake at night and a familiar list emerges: war, cyberattack, artificial intelligence (AI) and a warming planet.

Several of these issues feature in the World Economic Forum's Global Risks Report 2026, which ranks geoeconomic confrontation as the leading near-term risk. Sorting dangers into tidy boxes is understandable and often useful. But the gravest danger in coming years is unlikely to be any single item on the register. It will be what happens if several risks collide.

One crisis can quickly spill into another. A regional war can trigger sanctions and export controls, interrupting access to energy, minerals or advanced semiconductors and raising prices. Add a heatwave and a diplomatic confrontation can become an operational emergency in days.

A company that has prepared carefully for individual threats may not have a plan for combined shocks. Its blind spot will lie in the connections between risks and the absence of governance to manage them. This matters even more today because traditional shock absorbers – public debt, insurance – have less room to move.

As a result, more of the cost of colliding risks is likely to land directly on corporate balance sheets.

Risks interact in several ways. They cascade when disruption in one system travels into another. They compound when the first emergency consumes the resources needed to manage the next. They collide when separate pressures strike the same weak point.

These dynamics travel through markets and digital infrastructure at a great speed. At the same time, the risk landscape has become more complex. The unipolar period has passed and no stable replacement has emerged, leading to multipolarity without multilateralism. There are now more competing centres of power, but weaker institutions for managing their disagreements.

Economic interdependence, once prized as a source of efficiency and, many hoped, peace, is now also a source of coercive leverage. Governments increasingly use trade, finance and access to advanced technology as instruments of pressure. Restrictions invite retaliation, while efforts to remove one dependency often create another elsewhere.

Many middle powers are hedging – maintaining security ties with the US while trading extensively with China, for example. This may be sensible statecraft, but it means more regulatory friction and fewer common rules for companies.

Geopolitics now reaches deep into ordinary business decisions, and chokepoints are no longer limited to straits and canals. Semiconductor production and critical-mineral processing depend on a small number of countries and firms. The digital economy is similarly concentrated among a handful of cloud platforms and payment systems.

Decades of optimization have created an extraordinarily efficient economy, but one whose dependencies often remain hidden until certain risks collide.

Climate stress is also testing global trade, for example. A canal does not need to be blockaded to become a liability; it can run short of water. Drought restrictions sharply reduced traffic through the Panama Canal in early 2024, while low water has repeatedly constrained shipping on the Rhine in Europe. A super El Niño would put both under pressure at the same time.

Heat is less visible, but no less disruptive. It cuts physical work capacity and strains electricity systems. A 2019 International Labour Organization study projected that heat stress could reduce worldwide working hours by 2.2% in 2030, which is equivalent to 80 million full-time jobs. That estimate assumes warming is held to 1.5°C, which now looks optimistic.

And these effects spread further than the original weather event. Climate stress strains health systems, while transport and food costs rise and losses reach insurers and public budgets. Countries with ageing infrastructure and limited fiscal room have less capacity to respond.

AI is adding demand and concentration to many of the same systems. Investment is surging even as commercial returns remain uncertain. The Forum’s Global Risks Report 2026 recorded growing concern about a sharp AI asset-price correction.

At the same time, AI governance is struggling to keep pace with capability. General-purpose systems have improved rapidly in coding and research, as well as cyber-related tasks. But oversight is becoming harder as systems grow more capable and autonomous.

Labour disruption is also running ahead of adaptation. A 2024 International Monetary Fund (IMF) assessment estimates that almost 40% of global employment is exposed to AI, rising to about 60% in advanced economies. Exposure does not necessarily mean displacement, but weaker hiring or the disappearance of particular tasks may precede the creation of new opportunities. Political pressure will rise if disruption moves faster than economies can create credible alternatives.

AI also has a physical footprint. Data centres consumed about 415 terawatt-hours of electricity in 2024 – roughly 1.5% of global demand. And the International Energy Agency projects this could more than double by 2030.

During periods of extreme heat, households, factories and data centres may all compete for additional power. A colliding risk such as a technical failure could then disrupt payments and public services at the same time.

The financial crisis of 2008 showed how individually rational decisions can produce collective failure. Banks relied on similar assets, assumptions and short-term funding. Mortgage losses then spread through securities into the wider credit system, revealing fragility that no single balance sheet had fully captured.

The danger is greater now because conventional shock absorbers are strained. Insurance coverage is failing to keep pace with exposure, for example, with Swiss Re estimating a global natural-catastrophe protection gap of $424 billion in 2025.

And the IMF’s April 2026 Fiscal Monitor puts global public debt at just under 94% of GDP in 2025 and potentially 100% by 2029. High debt leaves governments less room to stabilize economies after a shock.

Companies should now expect to carry more of the cost when disruption occurs. Resilience therefore belongs in board discussions about governance and capital allocation.

Business leaders can take three steps to identify and govern the places where risks meet:

Start with the business services whose failure would threaten safety, liquidity or the company's ability to keep operating.

Identify the infrastructure and suppliers on which several critical services depend. Look further down the supply chain, beyond direct suppliers. Assign an executive owner to each critical point.

A cyberattack under normal conditions is one scenario. The same attack during a heatwave or funding shortfall is a different and potentially more damaging one.

Test whether one emergency response could weaken or disable another. Run exercises with incomplete information and senior leaders who disagree. This should result in clearly assigned responsibilities and specific changes to existing plans or budgets.

Boards should decide in advance who has the authority to shut down a system, and under what conditions. They should also determine who can release emergency funds and who is authorized to speak publicly on the company's behalf during a crisis.

In addition, boards should maintain practical alternatives for when the failure of a single facility or supplier could disrupt the wider business. This may include backup systems, additional capacity or alternative suppliers. Such measures should be funded selectively, based on whether they would contain the disruption, speed up recovery or preserve essential operations while the primary arrangement is restored.

Forecasting alone will not be enough in the coming years. Leaders must anticipate where risks converge, recognize a cascade before it escapes control and act while meaningful options remain available.

In a world of colliding risks, resilience depends on preserving room to move when the original plan fails.
