QE probably ends, but as powell said, he has other tools to support the economy. Another tool is to keep the usd low. We've seen it over the last few weeks, even though european and asian central banks have bought the usd, it has gone down. Now, the Japanese central bank has announced that it will not buy more usd. Therefore, i expect the usd to continue to fall.
As a result, the tariffs on u.s. American products imposed by European and Asian countries will be offset by the favorable u.s. dollar.
