LONDON, Jan 27 (Reuters) - The dollar held firm and the yen gained broadly on Wednesday as investors shied away from riskier assets on concerns about China tightening lending and U.S. monetary and political wrangling.
European shares were down 0.3 percent following losses in Asia and on Wall Street overnight.
"Asset markets are unsettled with knock-on effects into the pro-cyclical and commodity currencies, and I'd be looking for those currencies to continue to come under pressure", said Ian Stannard, senior currency strategist at BNP Paribas.
By 1245 GMT, the euro was flat on the day at 126.06 yen <EURJPY=R> after hitting a nine-month low of 125.25 yen. The next downside target was seen near its April 2009 low of 124.38.
"Euro/yen and Aussie/yen in particular are vulnerable to a more disorderly decline should we see further weakness, given Japanese margin accounts on the Tokyo Financial Exchange were holding near record longs on these two crosses as of Friday," analysts at RBC Capital Markets said in a note.
The yen trimmed gains versus the dollar to trade at 89.55 yen <JPY=> after hitting a six-week high of 89.14 yen on trading system EBS.
News of artillery fire between North and South Korea also helped the yen, a reaction traders said stemmed from a dip in South Korean shares.
"In spite of Japan's insipid growth, chronic deflation, the risk of more quantitative easing and threat of intervention, the yen retains its safe haven status," State Street analysts said.
The euro hit a six-month low against the dollar, hurt by concerns about the fiscal health of Greece and other peripheral euro zone countries.
The premium investors demand to hold 10-year Greek debt rather than benchmark Bunds hit a fresh euro lifetime high.
The euro <EUR=> later trimmed losses to trade flat on the day at $1.4075, after hitting a low of $1.4022. Traders said option-related demand was evident ahead of $1.4000.
