The euro was mixed in Asia on Wednesday after two eurozone bond auctions buoyed the embattled unit amid rising speculation that the European Central Bank (ECB) would restart a bond-buying programme. The European common currency bought $1.2556 and 98.69 yen in Tokyo morning trade, against $1.2565 and 98.68 yen in New York on Tuesday. The dollar was at 78.60 yen from 78.49 yen in US trade. Weak German business confidence data had weighed on the euro earlier this week, but the currency won some support after two debt auctions on Tuesday saw hard-hit Spain and Italy pay sharply lower borrowing rates.
