Global trade enters a year of tariff uncertainty
Global trade in 2026 is not entering as a space of freer flows of goods, capital, and technology, but rather as a system increasingly marked by political decisions, industrial subsidies, security assessments, and sudden regulatory shifts. This is precisely what the UN trade and development agency UNCTAD warns about, stating in its latest overviews that international exchange can no longer be understood only through the question of the volume of trade, but also through the question of the conditions under which that trade takes place. Companies therefore plan less and less according to the old rules of globalization, and increasingly according to assessments of geopolitical risk, state aid, tariff regimes, and the resilience of supply chains. In such an environment, the year 2026 does not look like a continuation of the old trade normality, but rather like a period in which the rules of global exchange are being rewritten, often outside the classic logic of the free market.
Although global trade in 2025, according to preliminary estimates, reached a record level and exceeded 35 trillion dollars for the first time, growth no longer also means greater predictability. UNCTAD estimates that the value of world trade in 2025 increased by around seven percent compared with 2024, with services once again growing faster than merchandise trade. But the same set of data also shows the other side of the story: the pace of growth is slowing, and market participants are increasingly facing not one major shock, but a series of smaller, yet frequent political decisions that complicate planning. This means that business strategies are being adjusted not only to raw material prices, interest rates, or demand, but also to announcements of new tariffs, changes in subsidy regimes, rules of origin for goods, security screenings of investments, and administrative barriers that increasingly have a geopolitical basis.
Tariffs return to the center of economic policy
One of the most noticeable trends is the return of customs duties as an active instrument of industrial and strategic policy. In its January overview for 2026, UNCTAD warns that global tariffs rose during 2025, primarily because of measures introduced by the United States, and that governments are expected to continue using tariffs in 2026 to achieve industrial and security goals. In other words, a tariff is no longer just a protective mechanism for an individual sensitive sector, but a means by which states try to shape investment flows, bring production back to politically acceptable locations, and reduce dependence on competing economies.
This change is also visible in official transatlantic relations. The European Commission announced on March 12, 2025, that it was responding to new U.S. tariffs on steel and aluminum with countermeasures against imports from the United States, describing the U.S. moves as unjustified. In later announcements from May of the same year, Brussels additionally opened consultations on possible new countermeasures and announced preparations for proceedings within the World Trade Organization. On the American side, the White House and the Office of the United States Trade Representative throughout 2025 and at the beginning of 2026 continued to publish decisions presenting tariffs as a tool for protecting domestic production, correcting trade imbalances, and responding to the issue of “economic security.” In practice, this means that the tariff regime can change faster than manufacturing companies can rearrange supply routes, contract new suppliers, or change investment plans.
Uncertainty becomes more expensive than the tariff itself
In one of its most cited conclusions from 2025, UNCTAD warns that uncertainty has become the “new tariff.” That summary describes the current state of international trade well. Companies can often cope with higher costs if the rules are stable and if they know in advance what regime will apply in six months or a year. What is much harder is doing business under conditions in which tariffs, exemptions, sectoral restrictions, or administrative requirements can change abruptly, by political decision, and without a long transition period.
In September 2025, UNCTAD pointed out that sudden changes in tariffs, subsidies, and trade restrictions had become a major source of global instability, and that uncertainty particularly affects countries and companies that do not have sufficient financial and logistical capacity for rapid adjustment. OECD is moving in the same direction, warning in its analyses of supply chain resilience that geopolitical tensions, regulatory uncertainty, transport bottlenecks, and climate disruptions are together changing the trade landscape. For exporters and importers, this means that risk is no longer measured only through the exchange rate or the price of transport, but also through the probability that a certain route, market, or input component will overnight become more expensive, slower, or administratively problematic.
That is precisely why 2026 is above all a year of unpredictability. The business sector is not faced only with the question of whether a country will increase tariffs, but also with a series of additional unknowns: whether a measure will apply to the finished product or also to its component parts, whether there will be exemptions for individual countries, whether rules of origin for goods will be tightened, whether new restrictions will also affect logistics, insurance, public procurement, or access to subsidies. In such an environment, even short-term uncertainty can be a strong enough reason for a company to postpone investment, change supplier, or increase inventories, which then additionally produces new costs and new delays.
Value chains are no longer moving only because of price
The second major change concerns global value chains. In the classic phase of globalization, production was moved to places where labor, energy, or logistics costs were more favorable. Today, the same decision is made using a much broader set of criteria: political stability, the country’s relationship with major powers, access to subsidies, export control rules, the possibility of concluding preferential agreements, and the resilience of infrastructure. UNCTAD therefore warns that geopolitics is increasingly redrawing the maps of trade and investment, while OECD emphasizes that the relocation of production within national borders is not necessarily a solution because it can reduce growth and weaken the resilience of the system in the long term.
In other words, the world is not abandoning international exchange, but reorganizing it. Terms such as nearshoring, friendshoring, and source diversification are in circulation, but behind those expressions lies a concrete business calculation: companies are seeking countries that are not necessarily the cheapest, but offer a politically more acceptable, regulatorily clearer, and logistically safer framework. This particularly applies to strategic sectors such as semiconductors, energy technologies, critical raw materials, pharmaceuticals, the defense industry, and advanced manufacturing. The consequence is that global production is not falling apart, but being reshuffled, and the winners are not always the largest economies, but also the so-called “connector” countries that manage to attract production and trade flows between rival blocs.
Still, even that adjustment is not without risk. In its work on trade patterns in a fragmented world, the IMF warns that short-term benefits from trade diversion do not also mean long-term security. Countries that profit as intermediary or alternative production locations can simultaneously become more vulnerable to future geopolitical ruptures, changes in investment flows, and new political pressures. This is an important message for smaller open European economies as well: the mere fact that part of production is coming closer to Europe does not automatically mean more stable development if the entire system remains dependent on frequent political interventions.
WTO remains important, but it is no longer the only framework
Additional weight to the uncertainty is given by the fact that the multilateral system of rules is under pressure. In its overview for 2026, UNCTAD states openly that reform of the World Trade Organization is at a crossroads. The WTO still remains the key institution for trade rules, notifications, and dispute settlement, but the practice of recent years shows that an increasing number of decisive moves are being made unilaterally, bilaterally, or within narrower political and economic alliances. This does not mean that the WTO is disappearing, but that its operational power has weakened precisely at the moment when predictability of rules would be most needed.
For companies, this is especially important because the weakening of the common framework increases the space for asymmetric and sudden moves by major economies. When key trade decisions are made outside a broader multilateral consensus, the costs of compliance, legal assessment, and political monitoring rise. Companies then no longer study only tariff tables, but also political documents, industrial strategies, national security laws, and subsidy programs. The business of foreign trade thus becomes closer to political risk management than to traditional exporting in which the main question was who offers a better price and faster delivery.
Developed and developing countries do not bear the same burden
Although uncertainty is global, its burden is not evenly distributed. UNCTAD continuously warns that smaller and less diversified economies and small and medium-sized enterprises find it harder to absorb shocks caused by unpredictable trade policy. Large multinational companies often have the ability to shift production, contract several suppliers in parallel, or temporarily store inventories. Smaller companies generally do not have such instruments. For them, even a short-term disruption in one phase of supply can mean loss of market, more expensive financing, or reduced profitability.
This particularly affects countries that rely heavily on a few export products or on a limited number of large markets. If such a country simultaneously lacks strong logistics alternatives, domestic subsidy capacities, or a broad network of trade agreements, its position is more sensitive. UNCTAD has repeatedly stressed that it is precisely smaller and poorer economies that are the most exposed to rising costs and trade volatility. In that sense, 2026 is not only a year of global reshuffling, but also a year in which differences in resilience among states may deepen further.
Europe between openness and industrial defense
For the European Union, current circumstances create dual pressure. On the one hand, the European economy depends heavily on international exchange and a relatively open trade system. On the other hand, political pressure is growing to protect domestic industry from dumping practices, global overcapacity, and aggressive subsidy policies of other powers. That is why European trade policy simultaneously speaks the language of openness and the language of defense. Brussels’ reactions to U.S. tariffs on steel and aluminum from 2025 show this clearly: the Commission emphasized that it wanted to protect European workers, consumers, and businesses, but also that in doing so it sought to respond “swiftly and proportionately.”
At the same time, Europe is debating how to preserve industrial competitiveness in sectors that are crucial for the green and digital transition. This includes steel, batteries, clean technologies, raw materials, and a number of manufacturing branches in which energy costs, climate targets, and global competition are already creating strong pressures. If foreign trade uncertainty is also increasing at the same time, European manufacturers receive an additional layer of risk: in addition to questions of price and demand, they must also monitor possible changes in access to the American, Chinese, or other major markets. For exporters from Europe, this means that 2026 will not be a year in which it is enough to have a quality product, but a year in which regulatory preparedness, speed of adjustment, and the ability to manage supply risks will carry great weight.
Trade growth exists, but under different rules
It is important, however, to avoid the oversimplified picture according to which world trade is simply collapsing. Official data show that exchange is still increasing, and UNCTAD points out that services and trade among countries of the global South in 2025 outperformed the world average growth rate. This means that globalization has not disappeared, but is transforming. Instead of a single, relatively linear system, a mosaic of different regimes, agreements, preferences, and restrictions is increasingly emerging. In that mosaic, growth can exist, but it is not necessarily even, politically neutral, or institutionally simple.
That is why the notion of success in international trade is also changing. It used to be crucial to enter a new market with a competitive price and reliable logistics. Today, compliance with regulatory rules, the ability to prove the origin of goods, the capacity to switch to alternative supply routes, understanding subsidy frameworks, and assessing the political sustainability of the entire business model are equally important. Under such conditions, trade looks less and less like a spontaneous result of market forces, and more and more like a combination of market efficiency and strategic positioning.
What 2026 means for companies and governments
For companies, 2026 will above all be a year in which planning must become more flexible. This implies more detailed supplier mapping, greater reliance on multiple supply sources, more careful monitoring of the trade policy of major powers, and greater readiness for rapid changes of contracts, routes, and markets. For governments, especially in smaller open economies, the challenge is even broader: how to increase resilience without closing markets, how to protect strategic sectors without entering into an expensive and unsustainable subsidy race, and how to remain attractive for investment in a world in which investors increasingly seek political predictability just as much as tax or cost advantages.
The central message of the latest international analyses is therefore quite clear. It is no longer enough to say that the world is moving toward greater protectionism. It is more precise to say that it is entering a period in which trade remains large and important, but becomes significantly more political, more complex, and more expensive to manage. Tariffs have returned, regulatory requirements are multiplying, supply chains are being reshuffled, and multilateral rules no longer guarantee the level of stability to which markets had become accustomed in previous decades. That is precisely why today’s economic story is no longer only how much is traded, but under what political conditions, with what risks, and with how much room for adjustment.
