All in 51 percent of all European Government bonds are trading at negative yields, and just over 30 percent of all investment grade corporate bond issued in Euro.
The percentage of negative yielding debt amongst junk-rated corporates is small. Bank of America ML estimated that the percentage of BB-rated European corporate bonds with negative yield rose from 0.225% at the end of May to 1.5% at the end of June. Back then, 14 companies had junk-rated bonds rated BB or lower with negative yields, with total market value of $3 billion.

Meanwhile, Greek Government bonds auction this week went into a massive demand overdrive. Greece sold more than EUR13 billion worth of 7-year bonds, almost EUR11 billion more than it planned originally, at the yields of 1.9 percent, or 2.4 percentage points above the Eurozone benchmark average. The spread to Eurozone benchmark has now fallen from 3.73 percent in March sale. In fact, U.S. 7 year bonds are selling at a yield of 1.97 percent, implying lower yields for Greek debt than the U.S. debt.
Here is the chart plotting Euro area sovereign yield curves for AAA-rated and for all bonds:
The yields on AAA-rated debt are negative out to 13 years maturity, and for all bonds to 8 years maturity.
