Can the global economy stabilize with 'Acute' uncertainty looming?

In its October 2025 World Economic Outlook (WEO), the International Monetary Fund (IMF) slightly revised upward its global growth forecast, but stressed that the overall pace of expansion remains subdued. The Fund noted that while recent policy adjustments—particularly the easing of some tariff measures—have brought limited relief and helped stabilize trade relations in certain regions, the broader picture is still clouded by what it described as “acute uncertainty.”

This uncertainty stems not only from ongoing trade frictions and uneven fiscal responses but also from deeper concerns about the durability of global demand, the fragility of financial markets, and the credibility of key institutions. The IMF warned that despite signs of resilience in early 2025, confidence remains fragile and heavily dependent on the trajectory of policy decisions in the months ahead.

Investors are taking notice. Market participants are increasingly questioning how long equity markets, particularly in the United States, can sustain elevated valuations in the face of moderating growth and rising geopolitical risk. The divergence between buoyant financial markets and a slowing real economy has become a central theme for both analysts and policymakers, highlighting the complex interplay between sentiment, policy, and macroeconomic fundamentals.

Against this backdrop, the question is no longer whether the global economy can grow—it is whether it can stabilize amid an environment where every sign of recovery is offset by new sources of volatility.

Global growth rate expected to drop a full percentage point in 2025

At a time of mounting uncertainty and shifting trade policies, the IMF’s April 2025 World Economic Outlook downgraded its forecast for global growth by half a percentage point, to 2.8 percent. The revision reflected the dual impact of rising tariffs and policy uncertainty—tariffs acting as supply shocks for the countries imposing them and demand shocks for those targeted, while uncertainty weighed on investment and consumption across all regions.

By midyear, some moderation in trade measures brought limited relief. The IMF’s July update revised global growth slightly higher, to 3.0 percent, as certain tariff increases were rolled back from their April peaks. Yet the broader picture remained one of deceleration. After a surprisingly strong start to the year, activity began to lose momentum, confirming the IMF’s warnings that resilience would likely give way to slower expansion in the second half.

According to the Fund, global growth is now expected to ease from 3.3 percent in 2024 to 3.2 percent in 2025, and further to 3.1 percent in 2026. While this represents a modest improvement from midyear projections, it remains about 0.2 percentage point below pre-tariff expectations outlined in the October 2024 WEO. The slowdown reflects ongoing headwinds from uncertainty and protectionist measures, even though the initial tariff shock was less severe than feared. On a year-end basis, the IMF estimates that global output will expand by only 2.6 percent in 2025—down a full percentage point from 2024’s 3.6 percent pace—highlighting the growing fragility of the global recovery.

What is driving the global slowdown?

Behind the IMF’s downgraded forecasts lies a complex mix of policy shifts, temporary distortions, and rising geopolitical tensions. As details of new fiscal and trade measures come into clearer view, growth prospects are being reshaped in real time.

Several advanced economies have recently introduced significant policy changes. Some have reduced international development aid and tightened immigration rules, potentially constraining labor supply and slowing productivity growth. Others have adopted more expansionary fiscal stances in an effort to cushion domestic demand—moves that may provide short-term support but raise questions about debt sustainability and cross-border spillovers.

Much of the global economy’s earlier resilience appears to have stemmed from short-lived factors, including firms rushing to front-load trade and investment before new tariffs took effect, and companies adjusting inventory strategies amid supply chain uncertainty. As these temporary supports fade, underlying weakness is becoming more apparent: trade volumes are easing, industrial activity is softening, and labor markets are showing early signs of cooling.

Inflation dynamics are also shifting. The pass-through of tariffs to U.S. consumer prices, initially limited, now looks increasingly likely to accelerate, adding pressure to already stretched household budgets and complicating monetary policy in key economies.

Persistent policy uncertainty remains a key risk. If prolonged, it could further weigh on business confidence, discourage capital spending, and slow hiring. A renewed escalation in trade tensions—whether through higher tariffs or new non-tariff barriers—could undermine investment, disrupt supply chains, and erode productivity. Restrictive immigration policies, particularly in aging economies facing skill shortages, could exacerbate labor constraints and limit potential output.

Financial vulnerabilities add another layer of concern. Rising borrowing costs, larger fiscal deficits, and higher rollover risks for sovereign debt leave some countries exposed to abrupt market repricing. These fragilities were underscored last week when renewed trade-war rhetoric rattled markets: President Trump’s threat to impose a 100 percent tariff on Chinese goods in response to Beijing’s export restrictions on critical minerals briefly sent global equities lower before partial recovery.

As IMF Chief Economist Pierre-Olivier Gourinchas observed, “The flare-up last week is an example of how these tensions can resurface very quickly and affect the outlook.” His warning captures the central theme of the current environment—an expansion still standing, but increasingly fragile, under the weight of “acute uncertainty.”

Fragile Confidence in AI and Policy Institutions Adds to Global Risks

Beyond trade tensions and fiscal uncertainty, a potential correction in the technology sector—particularly in artificial intelligence (AI)—poses another risk to the global outlook. For much of the past year, AI-driven optimism has fueled record valuations and significant corporate investment, turning technology into one of the few bright spots in an otherwise uneven global expansion. Yet mounting evidence suggests that the boom may be entering a more fragile phase.

Analysts warn that expectations around AI-related productivity gains may be running ahead of reality. A wave of disappointing earnings or weaker-than-expected efficiency improvements could trigger a broad repricing of technology stocks, abruptly ending the AI investment surge that has helped sustain market sentiment since late 2023. Such a correction would not only weigh on equity markets but could also reverberate across credit markets and business confidence, creating potential spillovers for macro-financial stability.

Market leaders are increasingly vocal about these risks. JPMorgan CEO Jamie Dimon cautioned this week that “elevated asset prices” remain a “category of concern,” noting that while corporate profits and consumer spending are holding up, valuations and credit spreads look stretched. “You have a lot of assets out there which look like they’re entering bubble territory,” Dimon said, warning that any reversal could be sharp once sentiment shifts.

Investor data echo those concerns. Bank of America’s latest Global Fund Manager Survey cited an “AI equity bubble” as the top global tail risk for the first time since the survey began, underscoring how concentrated investor positioning has become. The enthusiasm has been matched by aggressive corporate spending: Google recently announced a $15 billion investment to build its largest data hub outside the United States, in India; AMD shares climbed after unveiling a new chip partnership with Oracle; and Walmart expanded its collaboration with OpenAI to roll out AI-driven retail tools. Meanwhile, OpenAI has been securing long-term infrastructure and chip supply deals with Nvidia, Broadcom, and AMD—moves that, while strategic, have also deepened the perception of a self-reinforcing investment cycle in the sector.

If AI returns fail to meet expectations, the resulting market correction could undermine confidence more broadly. The technology sector’s outsized weight in major equity indices means that any sharp adjustment could spill into broader asset markets, tightening financial conditions and amplifying volatility across regions.

At the same time, concerns are emerging about the weakening independence of key economic institutions, notably central banks. In several economies, growing political pressure has threatened to erode policy credibility—particularly as governments face the dual challenge of high debt and slowing growth. Reduced confidence in statistical data, budget transparency, or monetary discipline could undermine the ability of policymakers to respond effectively to shocks, amplifying the economic cost of missteps.

Taken together, these factors—an overextended AI sector and the potential politicization of economic institutions—add new dimensions to the “acute uncertainty” highlighted by the IMF. They underline how fragile the balance remains between optimism and risk in the global economy, where sentiment-driven markets and policy credibility continue to act as both pillars of strength and potential points of failure.

Can the global economy stabilize amid acute uncertainty?

The IMF’s latest assessment paints a world economy still expanding, but increasingly at risk of losing its footing. Growth remains uneven, supported by strong labor markets in some advanced economies and continued momentum in parts of Asia. Yet these pockets of strength are overshadowed by a constellation of risks—geopolitical tensions, protectionist policies, overstretched asset valuations, and eroding institutional independence—that collectively make the recovery fragile.

What distinguishes the current environment is not the presence of any single shock, but the simultaneity of many. Trade disruptions and restrictive immigration policies are colliding with shifting fiscal priorities and tightening financial conditions. The AI sector, once a symbol of technological optimism, is showing signs of overheating, while political interference in monetary policy threatens to undermine the credibility on which stability depends.

In this context, stabilization will require renewed confidence in institutions and rules-based cooperation across borders. The IMF has called for coordinated efforts to maintain open trade channels, strengthen fiscal frameworks, and safeguard central bank autonomy. Such measures are essential to anchor expectations and prevent temporary market turbulence from turning into a prolonged slowdown.

For now, the global economy appears to be navigating a narrow path between resilience and fragility. The modest upward revision in growth forecasts offers some reassurance, but the margin for error remains thin. Whether the global economy can stabilize will depend less on avoiding shocks altogether than on governments’ ability to manage them without compromising credibility or confidence. In an era the IMF rightly calls one of “acute uncertainty,” steadiness of policy and clarity of purpose may prove the most valuable assets of all.
