Here's a reply post in the hopes that I'll either set the record straight (and save someone a lot of grief) or I'll learn something I hadn't thought of (it happens).
Predicting the future is hard. I'll believe higher trade tariffs when I see them. So far new tariffs have been just a diplomatic tool --none for Canada/Mexico/Columbia/etc. & plenty for China.
... raise tariffs on imports to the exact same tariff hat country has on US goods....
The U.S. has few/none tariffs on Panama because of CAFTA, and Panama has HUGE tariffs on U.S. cars. Sure, the U.S. could levy huge tariffs on Panamanian built cars but there aren't any.
...Trump thinks that a trade deficit is bad for some reason...
We don't really know that. All we know is that he SAYS a trade deficit is bad for some reason. My guess is that he SAYS that as a diplomatic tool to induce better bargaining results.
...Your answer below seems to say that the currency values balance out any trade deficit. I'm not sure ho that works...
It's simple enough to understand, If an American buys $1,000 worth of Chinese lithium and some Chinese guy buys $1,000 of Google stock then there's no change in the yuan/dollar rate. We get a $1k increase in the "trade deficit" and a $1k increase in the capital surplus. fwiw, we also get a lot of depreciation of the yuan because many believe the Chinese economy is tanking. That in turn means that the $1,000 buys more and more lithium every day.
...if I buy a Mercedes, and pay $100,000 and Germany ends up with a $50b trade surplus...
--because while you paid $100,000 to some U.S. dealer who shipped the car from the Mercedes factory in either Alabama or South Carolina depending on the model --
OK, I know what you're trying to say here. You bot $100k of German goods while other Americans spent $49,999,900,000 on VW's & beer and that's a $50B "trade deficit". At the same time a bunch of Germans bot $50B worth of S&P 500 stocks'n'bonds. At the same time the euro is falling w/ the dollar because Europe's economy is going nowhere while the U.S. is doing OK.
... I'm no seeing the big picture problem Trump sees with long term massive trade deficits. What bad thing happens?...
My take is that Trump SAYS the trade deficit is bad and he uses tariffs for isolating bad countries like China where he stops buying their lithium and buys it for the Ukraine instead. Fine w/ me.
... the Fed nor Treasury needs to send money overseas...
That stuff is all done electronically these days.
...to cover a trade deficit, its all handled by banks and currencies, correct?
The trade deficit (what the econ geeks call the "current account deficit") is covered by the capital surplus. There's no loss of money by the U.S. The only reason we hear about a "trade deficit" problem is because some people just love problems even if they're bogus.
