Comments from Federal Reserve Dallas president Fisher have been cited as the reason for the strong gains in the USD (link here and here).

He may have been one source as a catalyst ... but to say he caused the move .... nope.

Earlier I had comments from a Tokyo analyst on 122 as potential USD/JPY resistance. Something to be aware of.
