TOKYO, Aug 20 (Reuters) - Japan's Nikkei average fell 0.3 percent to a one-month low on Wednesday, with bank shares such as Mitsubishi UFJ Financial Group <8306.T> hit by worries about the U.S. financial system.
Canon Inc <7751.T> and other blue-chip company stocks continued to be hurt by recent gains in the yen, which has exacerbated apprehension about their earnings outlooks.
Following a contraction in second-quarter gross domestic product, the Bank of Japan cut its assessment to describe the Japanese economy as "sluggish" - a term it hasn't used since the 1997/98 Asian financial crisis. [
]"U.S. financial worries are responsible for about 80 percent of the market fall here today," said Masayoshi Okamoto, head of dealing at Jujiya Securities.
"The rest is due to the eroding outlook for corporate earnings for the first half. The Bank of Japan used the word 'sluggish' for the first time in 10 years yesterday, prompting concerns that an economic recovery will be delayed."
The benchmark Nikkei <
> shed 36.51 points to 12,828.54 by the end of the morning trade, hitting its lowest level since mid-July.The broader Topix <
> slipped 0.5 percent to 1,229.23."Fears of stagflation -- rising inflation amid a global recession -- are emerging again now that oil prices are getting higher," said Tsuyoshi Segawa, equity strategist at Shinko Securities.
The dollar was little changed against the yen at 109.76 yen <JPY=>, having fallen back from a seven-month high of 110.67 yen hit last week. A stronger yen curbs exporters' profits when they are brought back home.
Oil prices <CLc1> rose about 1.5 percent on Tuesday as part of a broad commodities rebound triggered by weakness in the U.S. dollar.
U.S. stocks fell for a second straight session on Tuesday on fears that U.S. home finance firms Fannie Mae <FNM.N> and Freddie Mac <FRE.N> may need a government bailout.
Lehman Brothers <LEH.N> shares also had another dismal day after JPMorgan Securities forecast that the investment bank will take a further $4 billion in write-downs tied to losses on mortgage-related investments. [
