<p>As the U.S. dollar strengthens, overseas profits will decline when stated in dollars.

<p>NYU Prof Joseph Foudy said the US trade deficit was caused by a lack of domestic savings and that tariffs on China would just shift the deficit to other countries. <a href="https://finance.zacks.com/relationship-between-trade-deficit-savings-6835.html" rel="nofollow noreferrer">Zacks</a> says</p>

  <p>A country’s trade balance (current account balance) is the difference between the value of exports of goods and services and the value of imports of goods and services.

<p>So isn't Foudy really saying we have a deficit because we import more than we export? In other words isn't the lack of domestic savings identical to the deficit rather than its cause?</p>

Yes - he is saying there is a macroeconomic national accounts tautology, and seems to be suggesting a particular causality which they do not necessarily imply

And we are back to Triffins' Paradox, apparently one of the most under studied and relevant concepts of our time which would answer many of these questions.

when one nation's fiat currency is used as the world's reserve currency, the needs of the global trading community are different from the needs of domestic policy makers. That is the reason we have a trade deficit.

Understood in this light, rising U.S. trade deficits in the 1990s and 2000s were required to provide enough dollars to lubricate rising global trade:
