The euro declined to the lowest level against the dollar and yen in more than six months as Greece’s and Portugal’s budget crises spurred a retreat from riskier assets.

The euro fell on Thursday to its lowest level in more than six months to 1.3930 in Asia due to persistent concerns over the fiscal health in some smaller eurozone countries such as Greece and Portugal. The single currency rebounded strongly from the low on short-covering and reached an intra-day high of 1.4053 in European morning as ECB 's Gertrude Tumpel-Gugerell said it is time for fiscal and monetary policy to return gradually to normal after the emergency steps taken to combat the financial crisis. However, the single currency fell sharply again after European equities pared all of their early gains and dropped to as low as 1.3946 in NY morning before stabilizing. Euro ended the day down over 0.24%.

In other news, German unemployment rose by 6,000, compared to the consensus forecast of an increase of 18,000. German unemployment rate was 8.2% in January, in line with economists' forecast

Versus the yen, the greenback initially extended Wednesday's rally as regional stocks opened higher in Asia (N225 was over 1.5%) following Fed's rate decision. Risk appetite and active cross-selling in yen pushed the pair to 90.56 in European morning. However, the pair retreated on renewed risk aversions and the fall picked up more momentum after the weaker-than expected U.S. data. U.S. durable goods increased by 0.3%, much lower than the common anticipation of 2.0%. U.S. jobless claims came in at 470,000 (more than the expectation of 450,000) from the previous reading of 478,000. The pair reached intra-day low of 89.62 in NY mid-day and closed the day down over 0.05%.
