Denninger saying that the 5 year Treasury auction on 7/29 was a virtual fail:

http://market-ticker.denninger.net/a...ely-FAILS.html

1.923 BTC X 61.59% Primary Dealer bid = 1.18 BTC (PD), greater than 1.0. Or to put it a different way, but for the primary dealers the bid-to-cover was less than one, meaning that some of the issue would have been left on the table.
Thats a fail; but for the primary dealers the issue would not have subscribed.
Primary dealers are required to bid. That's the deal in exchange for their being named as "primary dealers." For this reason short of thermonuclear war you will never see an actual (BTC < 1.0) "fail" on a US Treasury Auction - Treasury has rigged the process so as to insure that cannot be reported.
The 7 year auction on 7/30 was much better, but again the foreign and indirect bidder portion was very high.

Furthermore while this 7 year security is quite new, the actual interest rate in the first issue: 3/2/2009 is more than 0.5% lower than this latest one
