Will The Dollar Continue To Fall?

Authored by Jim O’Neill via Project Syndicate,

There are not only cyclical but also structural and even systemic factors that may make continued dollar weakening more likely. Warning signs in the US economy are flashing red, and most other countries are urgently looking for ways to reduce their economies’ dependence on Donald Trump’s America.

Although I no longer live and breathe the markets on a daily basis, I have never forgotten some key lessons I learned early on as an economist working in the financial industry: it is much easier to be wrong than right.

Consider one of the big, early surprises of 2025.

Late last year, following Donald Trump’s election victory, the US dollar was steadily rising, reflecting widespread expectations of relatively robust US economic growth, additional fiscal stimulus, and new or somewhat higher tariffs that supposedly would strengthen the dollar further. Instead, the dollar has been declining sharply.

Something else I learned early on is that, given the size and depth of the foreign-exchange market – where all known information gets priced in very quickly – it pays to be skeptical of overwhelming consensus views. Often, some element of the consensus outlook proves rather questionable. For example, I found it odd that so many forecasters saw tariffs as pro-dollar and unlikely to be overly disruptive to the US economy, despite being a net negative for US consumers.

Then there is the fact that some of Trump’s closest economic advisers have spoken openly about the need for other currencies to be stronger. That is why they have been pushing some new version of the famous 1985 Plaza Accord, whereby Japan and Germany agreed to strengthen their own currencies against the dollar to placate the United States. The so-called Mar-a-Lago Accord is supposed to do the same.

What seems clear to me is that the Trump administration is focused on US manufacturing and its own definition of competitiveness, neither of which offers much basis for expecting a persistently strengthening dollar. True, the usual counter-argument is that tariffs are needed because the dollar’s strengthening cannot be stopped, given the “exceptional” US economy’s unrivaled merits. America is “exceptional.” It boasts deep, liquid financial markets and cutting-edge technology, and it is preeminent in security matters and superior to its peers in terms of overall growth.

If the dollar’s relative weakness in 2025 is merely a price correction, these fashionable arguments will likely re-appear and carry it upward again. And yet, there are cyclical, structural, and even systemic factors that may make continued dollar weakening more likely.

On the cyclical front, recent high-frequency data point to a near-term softening of the US economy, with the closely watched Federal Reserve Bank of Atlanta’s GDPNow tracker forecasting negative growth for the first quarter of this year. Of course, it is too early to know whether this will be borne out. But while it could be just a temporary or technical artifact of the data, it is hardly the only warning sign. The latest business and consumer confidence surveys also give cause for concern.

Moreover, even people outside of the financial industry are becoming more unsettled about future inflation. The latest University of Michigan five-year inflation expectations survey (one of my own favored indicators) shows a rise to 3.9% – the highest in more than 30 years. If this trend persists, watch out.

Some analysts argue that this index is not as reliable as it once was, owing to changes in the survey methodology and the suspicion that Democratic voters are more inclined than Republicans and independents to respond. But professional pollsters know how to account for such discrepancies, and unless the actual calculation is somehow more biased toward Democrats, this argument is unconvincing.

In any case, many more commentators are suddenly talking about US stagflation, and owing to Trump’s erratic and aggressive behavior, other countries are not simply standing still. 

As I noted last month, policymakers in many countries – especially in Europe, but also in China – recognize that they must make changes to reduce their economies’ dependence on the US.

All these developments in the US and globally can account for the dollar’s recent decline. But there is also a more fundamental issue apart from what might otherwise be a “cyclical” decline. If Trump persists with tariffs and they do raise US inflation and create knock-on effects in the real economy, the longer-term equilibrium value of the dollar is likely to be less than it might have been. This, too, would warrant an adjustment in the price of the greenback – and perhaps a rather large one, if Trump keeps doubling down on his current approach.

That brings us to the systemic dimension. There is a long-running academic debate about why the dollar’s strength has persisted for so long, with some arguing that its value goes hand in hand with US power as a security guarantor and the dominant player in the post-World War II multilateral institutions. 

If the US is now abandoning these roles, others will be forced to stand up for themselves, and the dollar’s unquestioned dominance could finally come to an end.
