Admittedly I do not know much about tariffs so can someone explain to me why a bunch of countries have tariffs against US products in the first place? And, more importantly, why is the US just now responding to them? I really hate to see the semiconductor industry get caught up in this but seriously, why does the US have a trillion dollar trade deficit?
Dan,
I'll try to be concise but it's a long history and all goes back to 1944 and 1971.
1944 - Towards the end of WWII, there was a conference among nations called "Bretton Woods conference." It was decided in the conference that the world would move on from the British Pound-Sterling to the US Dollar as the Reserve Currency as by that time, the British empire was decimated from the 2 world wars and Britain was drowning in debt. US was already the largest manufacturer and the economy in the world by then. Given that all nations devalued their currencies during the 2 great wars, it was decided in the conference that all nations would use US$ as the Reserve Currency which in turn would be convertible to Gold so that US can not unilaterally print and devalue the US$. US Gold reserve at the time was ~25000 tons (basically the entire world economy was gone from the 2 wars; only US was left standing and therefore everybody exchanged their Gold for US goods).
For foreigners to use US$ as the Reserve Currency, they have to get US$, therefore they must export to the US to earn US$. US starts outsourcing industries to Europe (under Marshall plan), Japan and other places.
1944 - 1971 - US gets involved in Korean war, Vietnam war, Space exploration, Medicare expansion - all extremely expensive endeavors done without raising taxes and by running huge budget deficits; other nations, led by France, start questioning the US$ convertibility to Gold and starts repatriating their Gold. US Gold reserve falls from ~25000 tons in 1944 to ~9000 tons in 1971.
1971 - Nixon, on a Sunday night TV address, "temporarily" closes the Gold Convertibility window - never to reopen again. Now US$ is backed only by faith in the Government. Since all other nations tied their currencies to the US$, the entire world economy moves on from "Gold standard" to "Fiat standard".
Since Nixon knew that moving on from the Gold standard would unleash inflation by virtue of fiscal discipline being gone (can't print Gold but can print unlimited Fiat), one way to partly solve the issue was to normalize ties with China and bring its 1.5 billion "workers" into the picture (1974 - Nixon goes to China). US starts outsourcing in earnest - Consumer inflation does not rise as much as expected as more Fiat is balanced by more Labor supply from China and other developing Asian nations. US labor gets decimated - their "inflation-adjusted" income has not risen for the last 50 years. Since US "income" is now falling, Government has to run deficits as income taxes don't keep up with Fiscal spending. Government issues bonds which are in turn bought by countries running trade surplus with the US (e.g. China, Japan etc) - this is critical and completes the
Fiat loop --> US runs trade deficit --> US$ goes to foreigners who use it as the Reserve Currency and accumulate their national savings in US$, US Government bonds and US assets (US assets like Stocks did extremely well in the last 50 years but US labor did not) --> Government and people in the US go deeper into debt (Federal Reserve drives down interest rates, facilitating more borrowing) to finance the trade deficit --> the loop goes on. This loop works as long as foreigners recycle their US$ into financing the US government by buying the US government debt and by buying US assets like the S&P and NASDAQ.
A side effect of the above scheme is that there is a constant demand for US$, driving its relative value higher than other currencies. A national currency, US$ is wanted and used by 8 billion people - no other currency has this much demand. This puts US exporters at an extreme disadvantage as their goods are priced higher in local currency in the rest of the world than local production in those countries. Slowly US industries die off - first goes simple stuff like Clothing and then even High Tech manufacturing moves out - nothing can escape the gravitational pull of this currency mismatch. The constant demand and overvaluation of US$ also means that people who have good jobs in the US do very well as their US$ buys more foreign goods, but people who don't, suffer. The Rich - Poor divide widens. Our billionaires were never richer, yet ~52% of the population don't pay taxes because they simply don't earn enough.
Combined with the "Free Trade" policy, a new business model takes off - "make in low cost countries and sell in high cost countries" (Steve Jobs may have been the innovator, but it was Tim Cook who made Apple the financial behemoth it is today using this formula). This makes the trade deficit even worse.
Starting in 2014, China breaks the above loop and stops accumulating US$ and US treasuries as the People's Bank of China recommends to the Chinese government that it's better to buy commodities using US$ than accumulating more US Government debt as the end result is likely US will simply devalue US$ (by printing - simplifying) to pay back China. China starts buying mines in Africa, finances "Belt and Road initiative", builds infrastructure in developing countries using the trade-surplus US$ (thus converting Fiat promises into Real goods and obligations).
The situation is now such that US Interest payments exceed US defense budget; US defense industrial base depends on China and other foreign countries (paraphrasing Admiral Mike Mullen - We are borrowing from China to build weapons to face down China). US is now in roughly the same situation as Great Britain was a 100-years ago - a Financial and Military superpower without much of an Industrial Base; China is more like what the US was a 100-years ago - an Industrial superpower with the world's largest economy (by PPP - Purchasing Power Parity measures).
Trump's economic team (Scott Bessent, Stephen Miran) understands the above dynamics very well. The policies you see now are trying to reverse the above trends. I think the tariffs are here to stay; they may not stay at levels he announced on April 2, but certainly are not going back "Free Trade"/~2.5% average tariff for goods coming into the US. This is also why he talks about "External Revenue Service" (revenue from tariff).
I am skeptical about all the industries that left the US coming back to the US, but I can't imagine, given the Fiscal and Defense Industrial base situation, US putting up with critical industries such as High Tech manufacturing not coming back. While TSMC and Taiwan deserve all the credit, I don't believe the tide is in their favor.
