日本央行委员佐藤绫野：疲软的日元也通过增加进口成本给家庭和小企业带来负担。

Mitsubishi UFJ Morgan Stanley Securities strategist Shota Ryu said the yen's weakness is mainly driven by Japan-specific fundamentals — notably a widening digital services trade deficit and rising overseas investment by households and corporates. He said speculators have built large short positions in futures, indicating the move may be overheated and bolstering the case for government intervention to support the yen. Japan's finance minister Katayama said on Tuesday the government stands ready to take "decisive" action in the FX market if necessary.
