CREDIT WARNINGS
The euro fell as low as $1.3221, according to Reuters data, its weakest level since mid-December, while the yen edged up to its highest against the dollar in nearly four weeks, as mounting risk aversion also boosted the low-yielding Japanese currency.

]S&P has also warned Spain, Greece and Ireland in recent days that their credit ratings were under threat from the global credit crisis, another factor hurting the euro.
"The market has become sensitive to bad news such as credit outlook downgrading, especially with many investors now considering where they should be repatriating funds from, instead of investing to," said Masaki Fukui, a senior market economist at Mizuho Corporate Bank in Japan.
