ESMA Publishes Sovereign Bond Deferrals List
Summary
The European Securities and Markets Authority (ESMA) has published a list of supplementary deferrals for sovereign bonds under MiFIR, effective May 4, 2026. These deferrals allow for the omission of trade volume publication for medium-sized trades on liquid bonds until the end of the trading day.
What changed
The European Securities and Markets Authority (ESMA), in conjunction with National Competent Authorities (NCAs), has issued a decision allowing supplementary deferrals for sovereign bonds under the Markets in Financial Instruments Regulation (MiFIR). These deferrals, effective May 4, 2026, permit the omission of publication for the volume of medium-sized trades on liquid bonds until the end of the trading day. This measure aims to provide an adequate implementation period for trading venues, investment firms, and Approved Publication Arrangements (APAs) following the recent consultations.
Regulated entities, including trading venues and investment firms, must prepare to implement these new supplementary deferral rules by May 4, 2026. Compliance officers should review the published list and decision documents to understand the specific conditions under which volume publication can be omitted for sovereign bond trades. Failure to adhere to the updated transparency requirements could lead to regulatory scrutiny.

ESMA publishes list of supplementary deferrals for sovereign bonds
Post Trading 19/02/2026 The European Securities and Markets Authority (ESMA), together with National Competent Authorities (NCAs), has agreed supplementary deferrals that may be applied on top of the standard Markets in Financial Instruments Regulation (MiFIR) deferral regime for sovereign bonds.
ESMA and all NCAs, except the National Bank of Slovakia (NBS), have decided to allow the following supplementary deferrals: for trades of a medium size on liquid bonds in Group 1, the publication of the volume may be omitted until the end of the trading day.
The supplementary deferrals should start applying on 4 May 2026.
Background
As these decisions concern sovereign bond markets, which are critical and specific to each EU Member State, it was necessary to conduct consultations with the relevant regulatory bodies and financial institutions to arrive to a common approach.
The consultations resulted in a short time between the publication of the deferrals list and the start of the new regime on 2 March 2026, potentially causing implementation issues for trading venues, investment firms and Approved Publication Arrangements (APAs).
Therefore, a sufficient implementation period should be provided. In addition, to ensure a consistent application of the transparency regime, supplementary deferrals should apply from the same date, regardless of any differences in the timing of individual decisions adopted by Member States (for sovereign bonds issued by Member States), and the ESMA decision (for other sovereign bonds).
