Debt Office Commentary: Assessing the switch to single-price auctions for inflation-linked bonds

Publication 21 October 2025

Debt Office Commentaries are a series of essays in which employees of the Swedish National Debt Office provide in-depth expertise on current topics. Debt Office Commentary No. 2 2025 presents an evaluation of the Debt Office’s single-price auctions for inflation-linked bonds during the year.

Since the beginning of 2025, the Debt Office has used single-price auctions instead of multiple-price auctions for issuing inflation-linked bonds. The reason for the change is described in Debt Office Commentary No. 4 2024, “The choice of auction format is influenced by market dynamics”.

The Riksbank has continued to sell off its holdings of inflation-linked bonds through multiple-price auctions during this same period, which has provided a unique opportunity to evaluate the Debt Office’s change in auction format. The results presented in this Debt Office Commentary indicate that the change in auction format has contributed to a lower issue yield for inflation-linked bonds.

The authors of “Assessing the switch to single-price auctions for inflation-linked bonds” are Erik von Schedvin and Daniel Wayland.
