Looking for the $18 Trillion

Angry Bear Readers . . . once or twice a week, we are the recipients of commentary written by guest writer Erica York at The Tax Foundation. This is not a copy from a site that is simply pasted on Angry Bear. These are sent to the Angry Bear address. I then post them for Ms. Erica York, similar to what I do for other posters who may find such to be difficult. I am (we at Angry Bear are) very pleased to be the recipient of such commentary. I hope readers will take the time to read her words.

Looking for Trump’s $18 trillion

– by Erica York

In a $30 trillion economy where total private investment runs around $5 trillion a year, an investment surge of $10 trillion to $18 trillion is not realistic.  

Scale alone is reason for skepticism of the president’s claims, but so too is direction. Some sectors of the economy may expand due to protection, but that expansion comes at the expense of other sectors and overall productivity. Tariffs thus reduce economic output on net, and so they should shrink investment and the capital stock, not grow it.  

Even giving the White House every benefit of the doubt, if investment had increased by trillions, it should be noticeable in broad macroeconomic statistics.  

Start with total private nonresidential fixed investment, which excludes residential investment like owner-occupied homes and rental apartments, and focuses on  business structures, equipment, and intellectual property products like software and R&D.  

In 2025, the Bureau of Economic Analysis (BEA) reports that the United States saw $4.25 trillion in investment across those categories, up from $4.02 trillion in 2024 nominally, for an increase of $228 billion or 5.6 percent. Comparing annual rates in Q4 2024 ($4.04 trillion) to Q4 2025 ($4.36 trillion) yields a similar result, for a $319 billion increase or 7.9 percent nominally. In real terms, private fixed nonresidential investment was up about 4 percent year over year and 5.5 percent when comparing the fourth quarter annual rates. 

But President Trump’s claims are usually about a specific subcategory of investment: foreign direct investment into the United States. 

The BEA reports that foreign direct investment into the United States totaled $288.4 billion in 2025, down from 2024’s $292 billion, and lower than the nominal totals in 2023, 2022, and 2021 ($297 billion, $338 billion, and $406 billion).  

Everywhere we look, President Trump’s $18 trillion is nowhere to be found.
