On 08 Jul 2026 the Finanzagentur offered €6,000 m of the new 10-year Bund and allotted €3,902 m (65.0 %) to bidders — the rest, €2,098 m (35.0 %), was retained for secondary-market operations. That much is fact. “Failed to sell” is not: bids totalled €4,022 m, and the issuer rejected €120 m of them rather than accept lower prices. Retention this size is elevated against the long-run average, but the mechanism itself has operated in every single auction since 1999 — including the most oversubscribed ones.
§ 2.1 Anatomy of the auction
Concept · Auction mechanicsWhy a discriminatory-price tender allots less than it offers, and what “retention” then means, are explained in the primer — long‑and‑short · Auction mechanics (German).
The auction the video builds on, in the official numbers:
| Quantity | € million | Share of offer |
|---|---|---|
| Offered volume | 6,000 | 100 % |
| Total bids received | 4,022 | 67.0 % |
| Allotted to bidders | 3,902 | 65.0 % |
| Bids rejected by the issuer | 120 | — |
| Retained (Marktpflegequote) | 2,098 | 35.0 % |
| Average allotment yield | 3.09 % | |
The detail the “failed to sell” framing cannot survive: with €4,022 m of bids on the table, the agency allotted only €3,902 m. A seller desperate to move volume does not turn away €120 m of offers: the issuer took the bids above its price floor and retained the rest, to be sold into the secondary market over the following weeks by the Finanzagentur — the ordinary machinery of the tender, not a failed sale.
§ 2.2 Is 35 % retention abnormal?
Elevated, yes — 1.8 × the long-run average of 19.0 %. Unprecedented, no: the all-time record is 58.8 % (21 Aug 2019, 30Y — at a negative yield), and quotas above 30 % recur across the record. The size of the quota flexes with auction demand; its existence does not depend on it.
§ 2.3 Reading the evidence
The full announced volume was not allotted at auction: 65.0 % went to bidders, 35.0 % into the Bund's own holdings, and €120 m of bids were rejected on price. Every Bund auction since 1999 shows a retention quota; the 2023–2025 average was 18.9 % even with auctions twice covered.
A 35 % quota on a new 10-year issue signals that the agency preferred defending the price to placing volume that day — evidence of softer primary demand at that yield, and equally evidence that the issuer retains pricing power. “Could not sell” and “chose not to sell cheaper” are different failures, and only the second is in the data.
Whether retaining a third of an issue is prudent debt management or an alarming signal is a judgment; the video presents the judgment as if it were the fact.
