Yen slides under 160 to lowest level since 1986; Japan stocks fall

TOKYO -- The yen fell past 160 against the dollar for the first time since late April when the government and the Bank of Japan began to support the currency, stoking expectations of more intervention.

The dollar traded at 160.86 yen at one point Thursday morning, the Japanese currency's weakest since December 1986. The yen dropped to 171.79 against the euro, also the weakest level since the unified European currency was adopted in 1999.
