The growth fundamentals really weren't there for the euro. The U.S. has a strong economy, it has high yields and that's good for the dollar.

Sentiment was extreme and totally against the yen, and that's why we saw it getting stronger. When everybody is positioned for one outcome, then you've got to ask yourself where the marginal buyers are going to come from.

The market has got itself into a far-too-dovish spot given the tone of the Fed-speak. There is potential for rate expectations to rebuild and that should support the dollar.

Most of the underpinnings are economic.

It's wrong to assume that the dollar will start to fall as the Fed stops raising rates. What we could see is a transition to a structural support for the dollar as the trade position improves.

Dollars provided by the deficit are being soaked up by capital flows. It's important to consider both sides of the coin.

There was an observable extreme in market sentiment.

The story of the current account deficit allowed traders and analysts to justify any currency prices.

It's possible that the deficit actually becomes a positive factor for the dollar as people see it narrowing. That will allow the dollar to rally even as growth in the U.S. slows down and the Fed stops raising rates.
