CMC Markets chief market strategist Michael McCarthy said investors had panicked in the wake of the comments.
Mr McCarthy said the negative sentiment would probably last at least a few days.
``I've been talking to a number of big traders and investors. They're expecting wholesale selling across all markets tonight,'' Mr McCarthy said.
``There's little doubt in my mind that this is a panic at the moment.
``We're certainly pricing a lot worse than has actually occurred.
``Perhaps with hindsight, some of the comments that came from some of the leaders in Japan were a little intemperate in that they seem to have sparked quite a panic.''
