TOKYO (Reuters) -Japan's top currency diplomat on Monday issued a warning against speculative moves on the foreign exchange market as the yen fell below 149 per dollar. "We will monitor currency market moves including speculative trading with a sense of urgency," Atsushi Mimura told reporters, reviving a verbal warning tactic that his predecessor, Masato Kanda, frequently used. Separately, Katsunobu Kato, the nation's newly appointed finance minister, said the government would monitor how rapid currency moves could potentially impact the economy and would take action if necessary.
