After yesterday's impressive 3Y auction, moments ago the Treasury sold $39 billion in benchmark, 10Y paper, in what was a mediocre auction.

The auction, a 9-Year 10-Month reopening of cusip CPX8, stopped at a high yield of 4.282%, up from 4.217% last month and the highest since last August. It also tailed the When Issued 4.280% by 0.2bps, the third consecutive tail in a row.

The bid to cover dipped to 2.429 from 2.449, and was also below the six-auction average of 2.48.

The internals also disappointed, as foreign demand slumped from March with Indirects awarded 65.32%, down from 74.45%, and below the recent average of 68.78%. Directs offset much of this drop, rising to 23.88%, almost double the 12.83% in March and the highest since January. Dealers were left holding 10.8%, down from 12.7% the previous month, but in line with the average of 10.05%.

Overall this was a slightly subpar auction, especially after yesterday's stellar 3Y auction, but in light of the bid drop in yields across the curve and the lack of concession, it priced roughly where it should have and the market has barely reacted as one would expect.
