The Organisation for Economic Cooperation and Development (OECD) is sounding the alarm as the world economy enters a period of instability. The Paris-based organisation warned in its most recent outlook that the harsh tariff policies of U.S. President Donald Trump are beginning to hinder global development.
The OECD now projects a little lower 3.2% global economic growth in 2025 than it did last year, with a more severe decline to 2.9% in 2026. It contends that the increasing pressure of protectionist policies seeping into consumer markets, trade routes, and supply networks is the root cause.
Trump’s Approval Rating Slips as Americans Voice Economic Concerns
Trump’s Tariff Agenda
Trump has implemented one of the most protectionist trade policies in contemporary American history since taking office again.
- Tariffs of up to 50% have been applied to a variety of manufactured items, including steel and aluminium.
- These actions are not just directed at competitors like China; they also include more established friends like Canada, India, and the European Union.
- OECD data shows that the effective U.S. tariff rate has increased to 19.5%, the highest level since the Great Depression in 1933.
Global corporations are being forced by the increase in trade barriers to re-evaluate their investment choices, reroute supply lines, and rethink their production strategy.

Short-Term Resilience, Long-Term Strain
Interestingly, the OECD said that early in 2025, the global economy did better than anticipated. The cause: in order to temporarily increase production, several exporters hurried shipments to the United States before tariff deadlines.
However, these short-term benefits are gradually being replaced by more serious structural issues:
- Increased input costs are putting pressure on producers.
- Bottlenecks and delays are being caused by supply chain interruptions.
- A decline in export orders is eroding trust.
The OECD cautioned that the initial resilience is rapidly eroding and that the effects will become fully apparent by 2026, as seen by declining GDP growth and decreasing trade volumes.

Impact on American Families
Tariffs are being borne by average households, despite being presented as a means to safeguard American business.
- The cost of imported goods, including electronics, autos, and other home items, has increased.
- Growing expenses are forcing households to reduce discretionary expenditure by tightening household budgets.
- As domestic producers respond by raising prices, inflationary pressures are extending beyond imports.
As a result, middle- and lower-income families are disproportionately impacted by a hidden tax on American consumers.

The Labor Market Fallout Abroad
The effect is being felt by factories and workers in other nations. The following issues already confront export-driven economies that depend significantly on U.S. demand:
- The manufacturing and supply chain sectors are experiencing job losses.
- Temporary layoffs or shortened workweeks as businesses adapt to declining orders.
- Less safeguards for workers against downturns in emerging markets due to weaker labour laws.
The OECD issued a warning that protracted trade battles could increase inequality both within and across countries and jeopardise job security globally.

Ripple Effects on Investment and Confidence
Trump’s tariff measures have had the most pernicious impact on business confidence.
- Businesses are becoming more and more reluctant to invest in new supply chains or factories because of the unstable trade environment.
- Investors are moving their money to safer assets, which is making capital flows more erratic.
- The OECD issued a warning about a possible slowdown in innovation as businesses shift their focus from expansion and research to tariff management.
This uncertain environment runs the danger of starting a vicious cycle in which poorer investment now results in slower growth later.

A Shifting Geopolitical Backdrop
The global economy is being impacted by more than just tariffs. The larger geopolitical background was emphasised in the OECD report:
- Major power conflicts are on the rise, particularly the competition between the US and China.
- As countries seek “friendshoring” and lessen their need for enemies, supply chains are becoming fragmented.
- changes in European, Asian, and Latin American policies that make trading more difficult.
In this context, increased tariffs serve as an extra shock that exacerbates already-existing weaknesses in the global system.

Defending the Tariffs: The Trump Administration’s Argument
The Trump administration has continuously maintained that tariffs are required to safeguard American industry and jobs.
- U.S. manufacturing has been depleted by decades of globalisation, according to officials.
- They contend that tariffs level the playing field and compel trading partners to reach more equitable agreements.
- In order to achieve long-term benefits in industrial power and economic sovereignty, the White House maintains that temporary suffering is acceptable.
The tariffs are a component of a larger initiative to “rebuild America’s industrial base, no matter the cost,” according to one Trump official.

OECD’s Warning: A Broader Cost to the Global Economy
While acknowledging these objectives, the OECD cautions that the costs stretch well beyond the boundaries of the United States.
- The efficiency gains that have propelled decades of expansion are being diminished by the decline in global trade volumes.
- Emerging markets are disproportionately susceptible since many of them rely significantly on exports.
- Advanced economies also see a decline in investment, a decline in production, and an increase in political opposition.
The OECD urged nations to seek coordinated solutions that would stabilise growth rather than further destabilise it, and to refrain from erecting new trade barriers.

A Historical Comparison
When the Smoot-Hawley Tariff Act sparked retaliation and led to a collapse in international trade in the early 1930s, U.S. tariff rates were last this high.
Even though the world is more complicated now, economists are concerned about a similar spiral:
- U.S. trading partners’ retaliatory tariffs.
- The breakdown of the international trade system.
- A prolonged period of global trade stagnation.
The severity of today’s hazards is shown by the OECD’s contrast to that earlier era.
Looking Ahead: Can the World Adapt?
The key question is whether the world economy can adapt to a more protectionist future as economies around the world prepare for slower growth in 2026.
- Some nations want to lessen their dependency on the United States by diversifying their export markets.
- Others are protecting themselves from trade shocks by investing in domestic industry.
- Resilience is being given precedence over efficiency as multinational corporations experiment with regionalised supply chains.
However, the OECD cautions that these changes will take time and might not completely counteract the negative effects of higher tariffs.

Conclusion:
The OECD has issued a clear warning: Trump’s tariff-first approach is slowing the global economy and changing trade in ways that entail serious dangers, even while it may safeguard certain American businesses.
Higher living expenses are the result for American households. Loss of employment and weakened security are the costs for overseas workers. The cost to firms worldwide is uncertainty and lower investment.
The globe must decide whether to seek fresh multilateral cooperation initiatives or adjust to a protracted period of trade restrictions as the global economy slows into 2026. The stakes are extremely high for the US, its allies, and the world economy as a whole.
