The price of US protectionism

Tariff war, IMF prepares to cut global growth estimates

Director General Kristalina Georgieva warns: there will be 'significant reductions, but not a recession'. "Uncertainty has a cost and the longer it goes on, the higher it goes". Internal and external macroeconomic imbalances need to be addressed: 'Foreign deficits and surpluses can create fertile ground for trade tensions'

The International Monetary Fund is preparing to cut global growth estimates and to raise inflation estimates for some countries, as the Ocse and practically all national economic institutes have already done, along with the research departments of banks and corporations: this is the price of the tariff war triggered by Donald Trump. An alarm that has just been raised also by Federal Reserve and European Central Bank. Estimates, statistics and forecasts from the IMF will come next week, when the update of its World Economic Outlook will be published. In the meantime, the managing director, Kristalina Georgieva, anticipates that the new projections will reflect 'significant downturns, but not a recession'.

The scenario

.

In January, the Monetary Fund had set the expected increase in world GDP at 3.3% in both 2025 and 2026, after 3.2% in 2024. An already 'sluggish' pace and, moreover, exposed to the Trump unknown, which in recent months is proving to be as deleterious as feared. So much so that in March, the OECD had already cut its estimates for world GDP to 3.1% in 2025, 0.2% less than indicated in December. In 2026, growth would stop at 3%, 0.3% less.

On 16 April, the WTO warned that the tariff war will freeze global trade, which could see a drop of between 0.2 per cent and 1.5 per cent this year, depending on how high the tariff wall Trump intends to erect around the US.

The cost of uncertainty

.

Estimating the impact that protectionism will have on the world economy and on individual countries is not easy, in a framework continually redefined by the erratic nature that dominates the White House, between announcements, rethinks and relaunches, linked more to personal idiosyncrasies and power plays than to economic logic, from which the decisions on tariffs seem to be completely divorced.

Some firm points are there, however. In her customary speech anticipating the topics of the IMF meetings scheduled for next week in Washington, Georgieva emphasises, for example, that 'uncertainty alone has a cost'. This is seen every day in the markets. From finance to the real economy, 'in a world of bilateral tariffs, which can move up or down, planning becomes difficult. The result? Ships at sea not knowing in which port to set sail; investment decisions postponed; volatility; precautionary savings. The longer the uncertainty, the higher the cost'.

Faced with the risk of global shocks, Georgieva emphasised, 'economies are in a weaker starting position', weighed down by the rapid growth of public debt in just a few years.

Not only do tariffs dampen GDP by driving up the cost of imports, they also 'erode productivity in the long run, especially in smaller economies'. Nothing new, nothing undiscovered, in an economic theory that has been thoroughly researched and confirmed by empirical observation. "Protecting industries from competition, disincentives the efficient use of resources", firms are driven to seek exemptions, protections and subsidies, to the detriment of innovation.

Unbalances to be redressed

.

Easy to say, the path of dialogue and cooperation remains the priority in a multipolar world for the IMF. So is restoring public finances and addressing internal and external macroeconomic imbalances. Starting with domestic balances between savings and investment, which determine trade balances and capital flows. "Foreign deficits and surpluses can create fertile ground for trade tensions," Georgieva points out with understatement. Responsibilities and difficulties are widespread: countries with current account surpluses generally feel little urgency to return to a more balanced situation; on the other hand, the US, thanks to the dollar's role as a global reserve currency, benefits from 'a special ability to sustain deficits'.

The IMF then reiterates long-standing recommendations. China must promote growth in 'chronically low' private consumption. This means scaling back subsidies and state involvement in industry; strengthening welfare systems so as to reduce the need to accumulate private savings; and launching support measures for the real estate sector, which is in chronic crisis. Beijing should also 'embrace more warmly' the shift from manufacturing to services.

As far as Europe is concerned, Georgieva emphasises the reforms launched in Germany to increase public investment in defence and infrastructure, which will stimulate demand. However, the EU must complete its integration process: "It needs a banking and capital union. And it needs to reduce internal restrictions in the exchange of services'.

And the United States? They must finally come to terms with the mountain of public debt.
