Businesses around the world are increasingly concerned about the possibility of rare but highly disruptive events known as Black Swans. According to new analysis from the Allianz Risk Barometer, many companies believe a global supply chain shutdown or a widespread internet outage could have severe consequences within the next five years.
Black Swan events are unexpected occurrences with significant economic and social consequences. Past examples include the 2001 terrorist attacks in the United States, the global financial crisis of 2008, and the Covid-19 pandemic. Allianz Research estimates that the pandemic alone caused global GDP losses of about US$12 trillion between 2020 and 2023.
Beyond the immediate economic damage, such events can alter geopolitical relations and social systems for years. These long-term consequences mean businesses and policymakers continue to assess how similar disruptions could unfold in the future.
The Allianz Risk Barometer survey gathered responses from more than 3,000 risk management professionals worldwide. More than half of respondents, 51 percent, identified a global supply chain paralysis caused by geopolitical conflict as the most plausible Black Swan scenario that could affect their organisations within five years.
A large-scale internet outage ranked second, with 47 percent of respondents identifying it as a serious risk. The concern reflects rising awareness among businesses about the dependence of economic activity on digital infrastructure and the potential vulnerabilities associated with cyber risks and artificial intelligence technologies.
The results show similar concerns across Asia Pacific. Respondents in the region also placed supply chain paralysis and a global internet outage as the two most likely Black Swan events.
Supply chain disruption ranked first in China and Hong Kong, Singapore, and South Korea. By contrast, businesses in Australia, India, Japan, Malaysia, and Thailand were more likely to identify a global internet outage as the most plausible scenario.
Allianz Commercial CEO Thomas Lillelund said the interconnected nature of modern economies means that disruption can escalate quickly.
“Although Black Swan events are not seen to be immediately likely, these rare, high-impact scenarios are perceived as increasingly plausible and should be considered by executive boards given their potential consequences. Growing interconnectivity across both physical and digital supply chains means disruptions now cascade much faster and can turn into major losses. In today’s fragmented geopolitical environment, companies must double down on resilience and integrated risk management to ride out the next perfect storm.”
Geopolitical tensions are widely viewed as a major factor increasing the likelihood of severe global disruptions. Trade disputes, protectionist policies, and regional conflicts have already affected the flow of goods and raw materials across international markets.
Recent instability in regions such as the Middle East and the ongoing war between Russia and Ukraine have exposed vulnerabilities in shipping routes and logistics networks. These events have pushed supply chain resilience to the top of boardroom agendas.
Allianz Research estimates that a global supply chain disruption on the scale of the war in Ukraine could result in cumulative GDP losses of about US$1.5 trillion over two years. The economic impact would ripple across industries that depend on the steady movement of components, materials, and finished goods.
Political instability also ranks among the leading triggers for potential Black Swan events. Mass social unrest and political instability was identified by 29 percent of respondents as a plausible global scenario.
This risk was ranked within the top three threats in several regions. In the Americas, 31 percent of respondents cited it as a serious concern, while 41 percent of respondents in Africa and the Middle East did the same. In France, the figure reached 42 percent.
Financial instability is another scenario businesses are watching closely. Thirty percent of respondents said the sudden collapse of a major financial institution or a sovereign debt crisis could trigger a global liquidity crisis and severe market volatility.
The survey findings reflect how deeply interconnected modern economies have become. Physical supply chains and digital networks are closely linked, meaning disruptions in one system can quickly affect the other.
Concentration in certain sectors may increase these vulnerabilities. Economic activity in areas such as artificial intelligence infrastructure, semiconductors, rare earth processing, and transition technologies often relies on a small number of suppliers and specialised facilities.
Differences in risk perception also emerged when companies were grouped by size. Larger companies and multinational enterprises tend to view geopolitical supply chain disruption as their most pressing Black Swan scenario.
Among companies with annual revenues exceeding US$500 million, 55 percent selected supply chain paralysis as the most plausible threat. Mid-sized companies with revenues between US$100 million and US$500 million produced similar results, with 52 percent identifying the same scenario.
Smaller companies expressed different concerns. Among organisations with annual revenues below US$100 million, the leading worry was a global internet outage, cited by 45 percent of respondents.
For both mid-sized and smaller businesses, the collapse of a major financial institution ranked as the third most plausible scenario. Large corporations were more likely to focus on environmental risks, including the possibility of simultaneous climate disasters and energy grid failures.
Large multinational companies may feel better prepared to manage certain digital disruptions due to larger budgets and more diversified operations. Smaller organisations often rely on fewer systems and suppliers, which can increase their vulnerability to outages or service interruptions.
Michael Bruch, Global Head of Risk Consulting Advisory Services at Allianz Commercial, said businesses must accept that preparation for rare events has limits.
“Awareness of Black Swans and the need to build resilience has increased in recent years, but businesses can never fully prepare for rare high impact events such as a global outage or an unforeseen climate-related catastrophe. Building organizational agility, fostering a risk-aware culture and developing scalable response plans for a range of scenarios remain the most practical steps to best prepare for Black Swan events. Insurers can play a critical role in helping businesses strengthen their resilience in areas such as cyber risk and support more informed decisions when assessing and selecting critical suppliers.”
