The global uncertainty index has reached a record high in the last 36 years: what does this mean for the economy

While governments, markets and big companies try to pretend that another wave of economic instability can be waited out, the World Uncertainty Index shows something much harsher. The world is stuck in a state where risk has ceased to be the exception and has become the usual environment for trade, investment and political decisions. After the pandemic, the 2008 financial crisis, the September 11 attacks, the Iraq war and Russia’s full-scale invasion of Ukraine, it might have seemed that the limits of global anxiety were already known, but the data for 2025-2026 have destroyed this idea. The current record WUI shows that the global economy is living without a clear horizon, and in such an environment every decision becomes more expensive, the willingness to invest weakens, reconstruction slows down and the cost of any mistake increases.

The World Uncertainty Index has renewed its historical maximum

According to data from a group of experts from the International Monetary Fund (IMF) and Stanford University, which are updated quarterly, as of April 19, 2026, the World Uncertainty Index (WUI) has reached a record high since 1990. That is, over the past 36 years, it has reached a level for which the usual word “surge” is no longer enough. Now the world is observing not a one-time jump that markets experience and gradually leave behind, but a long strip of tension that does not recede quarter after quarter. Thus, in the first quarter of 2026, the WUI was 81,872 points, in the fourth quarter of 2025 – 94,947, in the third quarter of 2025 – 106,862, in the second quarter of 2025 – 80,038.

It should be noted that the most acute meaning of these data is revealed in the sequence of quarters. In the first quarter of 2026, the WUI was at the level of 81,872 points, in the fourth quarter of 2025 – 94,947 points, in the third quarter of 2025 – 106,862 points, in the second quarter of 2025 – 80,038 points. The points in the index do not mean a mathematical indicator of the “concentration of anxiety” in official economic reports. The algorithm calculates what proportion of the total number of words the word “uncertainty” occupies, and then multiplies this meager result by a million to get a whole number. In fact, these points are a scale of volume: they do not measure money or goods, but show how often professional analysts signal to businesses about the unpredictability of the situation, where the increase in the number indicates that the world is becoming less understandable for investors.

If we compare the last year with previous global shocks, it becomes clear that the world has entered a more severe and prolonged period of instability than the one it experienced in previous decades. During COVID-19 in 2019-2020, the WUI indicator was at a maximum of 55,685 points. The index responded to the global financial crisis of 2008-2009 by growing to 21,794 points. During the Iraq War, which began in 2003, the level of uncertainty rose to 34,455 points. The terrorist attacks of September 11, 2001, caused the WUI to jump to 25,156 points. The start of a full-scale invasion of Ukraine in 2022 triggered an increase in the index to 29,344 points.

Comparing these values ​​with the quarters of 2025-2026 leaves no room for ambiguity. The minimum of the last year, which is 80,038 points in the second quarter of 2025, turned out to be 24,353 points higher than the maximum of the pandemic, 58,244 points higher than the peak of the global financial crisis of 2008-2009, 45,583 points higher than the level of the war in Iraq, 54,882 points higher than the mark after the September 11 terrorist attacks, and 50,694 points higher than the indicator after the start of the full-scale invasion of Ukraine. The peak of Q3 2025, i.e. 106,862 points, makes this gap even more stark: it is 51,177 points higher than the COVID-19 peak, 85,068 points higher than the 2008-2009 crisis, 72,407 points higher than the Iraq war, 81,706 points higher than the September 11 attacks, and 77,518 points higher than the start of the major war against Ukraine.

These comparisons reveal something that is not apparent if you look at just one major event. Previous crises have hit the global economy hard, but each of them had a relatively clear center: the September 11 attacks were a specific security shock, the Iraq war was a specific military setback, the 2008-2009 crisis was a financial collapse, the pandemic was a global medical and economic shock, the start of the full-scale invasion of Ukraine was a sharp geopolitical blow to Europe and world markets. However, the last year looks different, because the index reached a record high not because of a single event, but because of the layering of several factors that simultaneously increase instability.

In the WUI data, these factors are: a difficult situation in geopolitics, trade wars, new military conflicts. In this combination, they create a qualitatively different type of pressure on the global economy. Geopolitical instability destroys trust in long-standing political agreements, trade wars disrupt traditional trade routes and increase nervousness in international business, and new military conflicts constantly add risk that cannot be quickly removed from the calculations. When these processes coincide in time, uncertainty no longer looks like a reaction to a single crisis, after which the system gradually returns to equilibrium. It becomes a long-term environment in which states, markets, and companies have to live.

Therefore, the WUI record over the past year is important not as an exclusively statistical fact, but as an indicator of changes in the very structure of global instability. Because of it, a high level of WUI increasingly appears in the reports of world analysts as one of the key signals of future risks for countries and their economies. The logic here is quite straightforward: the higher the level of uncertainty, the weaker the investment, the slower the global economy grows, and the more volatile the financial markets. When businesses don’t understand what the rules of trade will be, when governments change policy priorities, and conflicts expand the range of threats, capital goes into caution, and on such a scale it itself begins to slow down economic dynamics.

In conclusion, the WUI shows that past global shocks were severe, but they did not bring the world economy to such a level of record uncertainty, which would last from Q2 2025 to Q1 2026 in the range from 80,038 to 106,862 points. The last year turned out to be special because several large sources of instability merged into one long period of pressure.

How the World Uncertainty Index works and why people listen to it

The World Uncertainty Index appeared in 2018 as an attempt to measure what conventional economic statistics often show with a delay. Gross domestic product, inflation, or unemployment are not enough to understand when predictability begins to break down in the global economy. That’s why economists from the International Monetary Fund, Hitesh Ahir and Davide Fourcheri, together with Stanford University professor Nicholas Bloom, created an index that was supposed to provide a common scale for 143 countries and show where uncertainty has already become an economic factor, although official statistics have not yet had time to fully reflect this.

The basis of this index is not counting money, production, or prices, but text analysis of professional analytical reports of the Economist Intelligence Unit. At the same time, quarterly reviews are taken for each country, which are prepared for investors and big business, and then an algorithm counts how often words related to uncertainty appear in these texts. After that, the number of such mentions is correlated with the total volume of text. The more often analysts write about uncertainty, the higher the index becomes.

As already noted, WUI points do not mean percentages, dollars or the number of crises. They are index units that translate the frequency of mentions of uncertainty in reports. In essence, they show how often professional economic observers are forced to record instability, lack of clarity and difficulty in forecasting. When the index value increases sharply, this means that the environment for economic decisions has become much less clear.

The strength of this approach is that it allows you to see a crisis before it fully manifests itself in traditional indicators. Businesses, investors and governments first encounter uncertainty, postpone decisions, review risks, limit investments, and only then these processes turn into weaker growth, falling investment or nervous markets. In this sense, the WUI measures not the crisis itself, but the moment when the professional environment no longer believes in a stable scenario. Because of this, the index is considered extremely useful and important as an early signal in the world, because it shows where predictability is weakening faster than it has time to be reflected in the reporting of states.

It should be noted that the WUI differs from other uncertainty indices in its scale. Before its appearance, similar tools mostly concerned individual large economies, primarily the United States or Britain. The new approach made it possible to compare countries with each other using a single methodology, as well as to see how one shock spreads around the world. If, for example, a trade decision by a major power, a military conflict or a political turning point triggers a wave of anxiety far beyond the borders of the source country, the WUI shows this much faster than many other indicators.

The history of WUI jumps also explains why this indicator has become important for large analysts. It recorded the strongest waves of growth after the September 11 attacks, during Brexit, against the backdrop of the US-China trade war, during the COVID-19 pandemic, and after Russia’s invasion of Ukraine. In each of these cases, the index responded to moments when the global economy lost clarity about rules, trade routes, security, prices, and policy decisions.

What does the latest WUI mean for Ukraine’s economy?

For the Ukrainian economy, the latest value of the World Uncertainty Index is important because it shows the general external environment in which Ukraine is forced to work, trade, raise money, and plan for recovery. The indicator of 81,872 points in the first quarter of 2026, even after higher values ​​in the second half of 2025, is not a signal of relief. It means that the global economy remains in a zone of very high nervousness, and therefore, for Ukraine, an environment remains where any decision on investments, loans, risk insurance, and long-term contracts is made much more cautiously than in calmer periods.

First of all, such an indicator hits those areas where Ukraine depends on the outside world the most. When global uncertainty remains at a level that exceeds the peaks of the pandemic, the financial crisis of 2008 and the outbreak of a major war in 2022, international capital becomes more selective, risk insurance becomes more expensive, and long-term investments are postponed until better visibility. This is especially sensitive for Ukraine, because the wartime economy requires not only current support, but also major decisions for years to come – from production and logistics to energy, infrastructure and reconstruction.

In addition, an equally important signal concerns foreign trade. When the global uncertainty index is so high, it usually means that the world’s major economies see their own growth horizon worse, are more cautious in purchasing raw materials, react more nervously to price changes and revise trade terms more often. For Ukraine, which is heavily dependent on exports, this means a more difficult sales market: weaker demand predictability, higher sensitivity to price fluctuations and a greater risk that external partners will delay decisions or change terms in the process.

Separately, this indicator sends a very unpleasant signal for the topic of reconstruction, which Ukraine so needs. Major reconstruction requires not only money, but also trust in the future, while a high WUI just shows that global trust in the foreseeable scenarios has weakened. In such conditions, it is more difficult for Ukraine to count on a quick transition from short-term solutions to long-term ones, from emergency financing to systemic investments, from survival support to development support. In other words, even if political support for Ukraine remains, the global background still makes major economic decisions slower, more expensive, and more stringent in terms of conditions.

At the same time, the issue of the state budget also looks different due to this same indicator. With high global uncertainty, donor countries, international financial centers, and large investors themselves live in a risk review mode, which means that any assistance, loans, or new financial mechanisms for Ukraine go through a more complex decision-making environment. This backdrop does not automatically mean a withdrawal of support, but it does mean something else: each new commitment becomes more politically sensitive, financially more expensive, and procedurally slower than in a world with lower uncertainty.

Another signal concerns currency, price, and energy vulnerabilities. When global uncertainty increases, commodity, energy, and logistics markets tend to react with greater volatility. This is important for Ukraine because any sharp changes in energy costs, transportation, critical goods imports, or external demand are more likely to translate into domestic economic pressures. In a war economy, this effect is felt more acutely, because the margin of safety is lower and the room for error in budget, trade, and macro-financial policies is much narrower.

Against this background, the latest WUI indicator gives a double signal for Ukraine – on the one hand, it is not as extreme as the peak of the III quarter of 2025, when the index reached 106,862 points. Thus, global anxiety is no longer at its absolute maximum of the last year. On the other hand, the level of 81,872 points is still so high that there is no need to talk about normalization. Hence the most accurate meaning of this indicator for Ukraine: no crisis in the past has brought the world economy to such records of anxiety as during the last year.

For the Ukrainian economy, this means that the current environment is unfavorable for long rates, rapid expansion of investments and calm planning of external flows. In this situation, reconstruction, investments, exports and budgetary sustainability will depend not only on domestic decisions, but also on how unstable the world around will remain.
