Interest-rate advantage is still the only game in town for the currency markets. There's no doubt the dollar can gain further.

They're going to repeat their optimism on the state of the economy. People are expecting rate increases sometime this year. So this is all going to give the yen strength.

The yen will stay under pressure because of interest rate differentials. I am not so confident how this rise in CPI will enhance the chance for a premature interest rate hike in Japan.

It takes comparably low amounts of orders to trigger moves. I don't think there's much meaning in it.

The dollar's cyclical factors are waning but they haven't banished totally. The market is keen on switching to structural dollar stress factors but it's too early -- we also had strong housing figures from the U.S. last week.

People are cautious about buying the dollar at the moment. The U.S. needs a lot of investment to fund the deficit and the bigger it gets the harder that task becomes.

It was a bad number, and traders don't have anything else important to trade off today.

There's been dollar weakness as people have scaled back rate expectations. The market has got the impression that the fantasy the Fed would go past 5 percent was exaggerated.
