Nobel Prize-winning economist Joseph Stiglitz has warned that President Trump’s trade policies are turning the United States into a “scary place to invest,” increasing the risk of stagflation as GDP growth has already slowed. The warning comes ahead of a new 10% import surcharge scheduled to take effect on February 24, 2026, layering fresh costs onto an economy that grew at a 1.4% annual rate in the fourth quarter of 2025. With tariff revenue now facing legal uncertainty and consumer prices set to climb, the collision of weak growth and rising prices that Stiglitz described is becoming harder to dismiss.
GDP Growth Already Losing Steam
The economy entered 2026 on shaky footing. Real GDP rose at a 1.4% annual rate in the fourth quarter of 2025, according to the Bureau of Economic Analysis advance estimate. That figure was weighed down by the October–November government shutdown; the White House has cited BEA analysis to argue the shutdown reduced fourth-quarter growth by about 1.0 percentage point. Without that disruption, GDP would have tracked closer to 2.4%, a pace more in line with recent trend growth and far from the boom conditions the administration has promised.
The BEA’s detailed breakdown of output by consumption, investment, government spending, and trade components shows the shutdown’s drag most clearly in reduced federal outlays and delayed contract activity. The White House has used that decomposition to argue that the partisan budget standoff is to blame for weaker growth, insisting that the underlying economy remains strong and poised to accelerate. Yet that narrative glosses over mounting evidence that trade frictions and tariff uncertainty are weighing on business sentiment. Even before the latest surcharge, firms were contending with higher input costs, volatile supply chains, and shifting rules that complicate long-term investment decisions.
Stiglitz Sees Stagflation Risk Building
In an interview with The Guardian, Stiglitz outlined a two-pronged mechanism through which tariffs can generate stagflation. On one side, he argued, the constant threat of new levies and the perception that rules can change overnight deter capital spending, particularly in sectors that depend on global supply chains. Companies that might otherwise expand factories or research operations in the United States instead delay projects or look abroad, eroding the investment component of GDP. On the other side, tariffs directly raise the price of imported goods and invite retaliation that disrupts export markets, feeding inflation even as growth softens.
Stiglitz’s warning that the United States is becoming a “scary place to invest” reflects a broader concern about the country’s institutional reliability. Investors watch not only headline tariff rates but also the stability of contracts, the predictability of regulation, and the willingness of courts to check executive power. If multinational firms conclude that U.S. trade policy is volatile or legally vulnerable, they may reallocate funds to jurisdictions with more predictable frameworks. Over time, that shift would show up in official cross-border investment statistics, with slower inflows into U.S. assets and potentially stronger flows into competitor economies. The lag in data means those effects will take time to confirm, but the policy trajectory is already shaping expectations.
A New 10% Surcharge Adds Pressure
The administration’s latest move intensifies the cost burden on importers and, by extension, on American consumers and businesses. A recent presidential proclamation invokes Section 122 of the Trade Act of 1974 to impose a temporary 10% ad valorem surcharge on most imports, effective February 24, 2026, for a period of 150 days. The document frames the measure as a response to “fundamental international payments problems,” language that echoes the statute’s balance-of-payments rationale, and it sketches out exemptions and annexes that carve out selected goods and partners. Even with those carve-outs, the breadth of coverage means the surcharge will touch a wide range of consumer products, industrial inputs, and capital equipment.
For firms trying to plan purchases, pricing, and inventories, the new levy amounts to an immediate, across-the-board cost increase layered on top of existing duties. Retailers that rely on imported apparel, electronics, or household goods face a choice between passing the surcharge through to shoppers or compressing already thin margins. Manufacturers that import components must decide whether to absorb the hit, reconfigure supply chains, or cut back on hiring and investment. Because the policy is explicitly time-limited but politically charged, many businesses are likely to hedge rather than commit to expensive adjustments. That hesitation can itself be a drag on growth, as projects are postponed until there is more clarity about whether the surcharge will be extended, replaced, or abruptly withdrawn.
Tariff Revenue Faces Legal and Fiscal Uncertainty
The pivot to Section 122 is also shaped by legal pressures surrounding earlier tariff actions. The administration has relied heavily on emergency authorities to impose duties in recent years, particularly the International Emergency Economic Powers Act (IEEPA), and the Penn Wharton Budget Model notes the resulting tariff programs face legal uncertainty, including scenarios that could reach the Supreme Court. The Penn Wharton Budget Model estimates that Customs and Border Protection had collected roughly $133.5 billion in IEEPA-based tariff revenue as of mid-December 2025, drawing on a combination of USITC, CBP, and Treasury data. If the Court ultimately rules that IEEPA was misused for broad tariff programs, some portion of that revenue could be subject to refunds, creating both budgetary uncertainty and a potential windfall for importers who can navigate the claims process.
Fiscal modelers have begun to explore what such reversals might mean for the federal balance sheet and for distributional outcomes across households and industries. One Yale-based analysis of a hypothetical 25% tariff package on key sectors such as automobiles, semiconductors, and pharmaceuticals finds that higher import taxes tend to raise consumer prices while delivering relatively modest net revenue once behavioral responses and retaliation are taken into account. Those findings suggest that even if the new surcharge survives legal challenge, it may not provide the robust, stable funding source that some advocates imply. Instead, the combination of potential refunds on past tariffs and uncertain proceeds from new ones could complicate fiscal planning just as demographic pressures and interest costs are pushing deficits higher.
Policy Choices and the Road Ahead
The administration continues to argue that its trade strategy will ultimately deliver faster growth by reshoring production and correcting what it describes as decades of unfair treatment by trading partners. In its public messaging, the White House has highlighted the shutdown’s drag on fourth-quarter GDP to claim that, absent what it labels the “Democrat shutdown,” growth would already be stronger and poised to accelerate in 2026. Supportive statements on the official presidential website frame tariffs and surcharges as necessary tools to defend American workers and restore balance in trade accounts. That political narrative resonates with some domestic constituencies, particularly in import-competing industries, but it sits uneasily alongside warnings from economists about the risks of stagflation.
Ultimately, the trajectory of the U.S. economy will depend not only on headline tariff rates but also on how businesses, consumers, and foreign governments respond. If firms continue to delay investment and households face higher prices on everyday goods, the combination of slower real growth and persistent inflation could validate Stiglitz’s concerns. Policymakers will be watching upcoming releases from BEA, including detailed national accounts tables that break down consumption and investment trends, for early signs of whether the new surcharge is dampening demand. For now, the United States finds itself at a crossroads: double down on aggressive, legally contested trade measures in the hope of long-term gains, or recalibrate toward a more predictable framework that prioritizes investment stability over tariff brinkmanship.
