I'm new in bonds, but it seem that a failed auction does not represent a shortage of demand: if that Bund had been for sale at a lower price, there would have been plenty of demand. Rather, the failed auction is a failure of the auction mechanism to find the price at which there is demand.
There is another deeper problem lurking beneath the surface. The purchase of a country's debt is based on faith that the government will pay the bondholders back in full. Could it be that investors in Europe are losing faith in their governments? That may be one reason for staying out of these markets.
On wednesday 12th, there is a bund issue. It's a "reopening".
I tried to find info, but still don't know what reopening means
Does anyone know at what time is it?
I would like to follow eurobund future in real time to see what happens.
I am confused about your first point. If, theoretically, an auction fails (i.e. goes uncovered), how exactly does this NOT indicate a lack of demand? This is, after all, an auction process, right...
Now, as to the practical matters, bund auctions, technically, can't fail (neither can gilt, nor USTs, really). The underwriting mechanisms differ, but ultimately there's always a bid (either Finanzagentur/DMO retains the remaining amount at will or the primary dealers submit sufficient bids). However, even if the bond gets picked up by someone, lack of demand sends a very clear signal to the mkt.
If anything, given the stance of the Central Banks in Europe, UK and US, I'd say investors should really worry a lot more about the fate of their USD and GBP holdings, rather than EUR. Obviously, it's a complicated game, with lots of factors at play.
A "reopening" or a "tap" is when the issued bond already exists and the auction is just to sell more of it.
Bund auction results normally come out arnd 10AM.
