For investors and governments alike, the global economic outlook has become harder to read than at almost any point in the past three decades. Mohamed El-Erian, the Wharton School professor and long-time market commentator, argues that this is not a temporary phase. In a recent essay, he contends that the world has entered an era of persistent instability, and that policymakers who wait for conditions to return to normal are preparing for a world that no longer exists.
El-Erian identifies a set of forces that are reshaping the economic landscape at the same time: armed conflict, the fragmentation of global trade, the disruptive arrival of artificial intelligence and the weakening of the international institutions that once coordinated responses to shocks. His central message is that outdated assumptions must be abandoned and replaced with a new framework built around growth, resilience and cooperation.
Why the Old Assumptions No Longer Hold
For much of the period between the end of the Cold War and the 2008 financial crisis, economic policy rested on a few broadly shared beliefs. Globalisation would keep deepening, supply chains could be optimised for cost, inflation would stay low, and central banks could smooth out most downturns. Those beliefs supported an era of cheap money and rising trade volumes.
Each of those pillars has since been shaken. The pandemic exposed the fragility of lean supply chains. The inflation surge of 2021 and 2022 showed that price stability could not be taken for granted, and forced the fastest cycle of interest rate rises in decades. Trade tensions between the US and China, and a wider turn towards tariffs and industrial policy, have weakened the logic of an integrated world market. El-Erian, who popularised the phrase ‘new normal’ after the financial crisis, has long warned against assuming that disruptions will simply fade.
Four Forces Reshaping the Global Economic Outlook
The first is conflict. Wars in Europe and the Middle East have disrupted energy and commodity markets, shipping routes and investor confidence. Beyond the direct human cost, they push governments to prioritise security over efficiency, raising defence spending and encouraging countries to bring production closer to home.
The second is trade fragmentation. As major economies use tariffs, export controls and subsidies to protect strategic sectors, the global trading system is splitting into competing blocs. That can raise costs, reduce the efficiency gains that trade once delivered and make it harder for smaller economies to plan.
The third is artificial intelligence. AI carries the promise of a long-awaited productivity revival, but it also threatens to displace workers, concentrate market power and create new risks that existing regulation is not designed to handle. The speed of adoption makes it harder for labour markets and institutions to adjust.
The fourth is institutional erosion. Bodies such as the World Trade Organization, the International Monetary Fund and the G20 played important roles in coordinating responses to past crises. Their influence has been weakened by geopolitical rivalry and by doubts about whether multilateral rules still serve national interests. Without a credible coordinating mechanism, shocks in one region can spread more easily.
Growth as the First Line of Defence
El-Erian’s framework puts growth at its centre. Many advanced economies are carrying high public debt after years of crisis spending, and the main sustainable way to manage that burden is to expand the economy. Faster growth raises tax revenue, creates room for investment and makes political compromise easier.
That requires more than monetary policy. Central banks were asked to do much of the heavy lifting after 2008 and again during the pandemic. A more durable approach relies on structural measures such as investment in infrastructure, education, skills and digital capacity, alongside a regulatory environment that encourages companies to innovate rather than simply defend market share.
Building Resilience Into the System
Resilience is the second pillar. The aim is not to eliminate shocks, which is impossible, but to make economies better able to absorb them. For governments, that can mean keeping fiscal buffers, diversifying sources of energy and critical inputs, and ensuring financial systems can withstand sudden moves in asset prices. For companies, it means accepting that the cheapest supply chain is not always the safest one.
There is a balance to strike. Too much emphasis on self-sufficiency can turn into protectionism, raising prices and lowering long-term growth. The challenge for policymakers is to reduce dangerous dependencies without walking away from the benefits of open markets. Readers can explore the reasoning in El-Erian’s essay for World Finance, which sets out why piecemeal fixes are no longer enough.
Why Cooperation Still Matters
The third pillar is international cooperation, which may be the hardest to achieve. Many of the biggest risks, from pandemics and climate change to financial contagion and the governance of AI, cross borders. No single country can manage them alone, yet trust between major powers is low.
El-Erian’s view implies that institutions must be reformed rather than abandoned. That could mean giving emerging economies a stronger voice in global bodies, updating trade rules to reflect digital commerce and state subsidies, and creating new forums for cooperation on technology. Smaller coalitions of like-minded countries may also step in where universal agreement is out of reach.
What It Means for Investors
For markets, a more unstable world tends to mean more frequent volatility, sharper swings between asset classes and a higher premium on diversification. Strategies that worked during the long period of falling interest rates and smooth globalisation may underperform. Investors may need to pay closer attention to geopolitical risk, supply chain exposure and the policy response in each region, rather than relying on broad global trends. In that environment, a shifting global economic outlook becomes a reason to stress-test portfolios regularly rather than a backdrop that can be safely ignored.
Conclusion
El-Erian’s argument is ultimately a call for adaptation. The global economic outlook will continue to be shaped by conflict, fragmentation, technological disruption and weaker institutions, and none of these forces is likely to disappear soon. Countries that invest in growth, build resilience and keep working with partners will be better placed to manage the turbulence. Those that cling to the old rulebook risk being caught out by the next shock.
