The European common currency gained against the yen and other majors except the dollar after the Japanese Finance Minister vowed to buy European bonds to support euro area economies.

Today, Japanese Finance Minister Yoshihiko Noda said that Japan will trail China to support the euro area debt-stripped nations through buying bonds issued by Europe's financial aid funds, where Japan may buy up to 20% of the issued bonds.

Euro zone is planning to sell AAA-rated bonds during this month to gather 16.5 billion euros to finance the Irish bailout. Japan will probably spend more than 1 billion euros to get the aforesaid stake.

Yet, the news could not lower pressure on the euro with speculations Portugal will be the third euro zone economy to get an EU-IMF bailout.

Yesterday, Portuguese bond yields and cost against insurance rose to record high which added to concerns that France and Germany would put pressure on Portugal to accept a rescue fund to lower tensions in markets.
