German Bund yields hit one-month lows on Tuesday and most other eurozone bond yields fell after European stocks fell sharply and European Central Bank policymakers hinted they might expand their stimulus programme. Spanish and Portuguese yields fell less than the others, held back by investor uncertainty over the outcome of looming elections in both countries.
The pan-European FTSEurofirst 300 stocks index fell 3.2 percent, encouraging investment in less risky bonds.
German 10-year Bund yields, which set the standard for euro zone borrowing costs, fell 9.4 basis points to 0.594 percent. Most other euro zone yields were down 5-9 bps.
Spanish 10-year yields were down 4.1 bps at 1.96 percent, while Portuguese yields rose 1.6 bps to 2.60 percent.
