I think that since December 2016 with the Fed's first rate hike, and the market's null reaction to that, the dollar went into a spiral, which will not end until we reach the bottom of the canal.

The market, people, traders, have lost confidence in the actions of the Fed and the US government, this week when the Fed announces a new rise, if it is only 0.25% more, the market will react Again punishing the dollar to more falls

The only way this changes is that the Fed will rise from 0.5 to 1% in a single blow. But that would be like shooting a bomb on Wall Street and on the same American debt.
