European Union Bonds: Definitions and Deferrals

The regulatory changes keep coming this month, with ESMA’s new supplementary deferrals coming into effect on the 4th May as well as an additional update on what constitutes an ‘EU Bond’.

What is an EU Bond?

Up until recently ESMA’s Group 1 category consisted of the following:

Bonds issued by an EU member state, the UK, US or EU

It was further restricted to:

Bonds with 10 years or less to maturity
A Fixed Rate Coupon
(i.e. no floating or inflation linked bonds were eligible)

In the above criteria, the EU referred to bonds issued out of the European Union Legal Entity (to be precise, under Legal Entity Identifier: 529900FZRK8FGMPEOM08).

On 12th May, ESMA released an update to their Manual on Post Trade Transparency1.

ESMA updated page 312 (footnote 52 of the manual) which changes the criteria for ‘EUSB’ bonds within the Group 1 category and now states:

For the purpose of clarification of the Table 2.2 of Annex III of RTS 2, the condition on the issuer/issuer country is considered met for (i) bonds issued by the European Investment Bank; and (ii) bonds issued by an international financial institution established by two or more Member States which have the purpose of mobilising funding and providing financial assistance to the benefit of its members that are experiencing or are threatened by severe financial problems. Hence those bonds should be classified in Group 1 (G1) provided the other conditions on remaining maturity and type of coupon are met. This approach reaffirms equal treatment between the bonds referred to in point (i) and (ii), and bonds issued by Member States and by the European Union.

As a result of the ESMA update, additional legal entities along with the European Union are eligible for inclusion as an EU Bond, these are:

ISSUER NAME ISSUER LEI TICKER*
European Financial Stability Facility 222100OW6UHQXNHKN143 EFSF
European Investment Bank 5493006YXS1U5GIHE750 EIB
European Stability Mechanism 222100W4EEAQ77386N50 ESM

*Most commonly used ticker, some issues may use alternative tickers, depending on the precise issue and platform.

The above three issuers have sat in Group 2 up until now, and Chart 1 below illustrates the typical deferral breakdown.

EIB is by far the most active issuer, but proportionally has the highest amount of very large deferred activity. This is because there is more large institutional volume on this issuer than on ESM and EFSF.

As this analysis reflects the data available to date, we do not see trades using the new supplementary deferral guidelines. As these instruments move into ESMA’s Group 1 category, it is likely the OMIS (volume omission) and FULO (full details) flags will increasingly be used as adoption rises (these flags were discussed in Propellant Insights Issue 33).

Looking ahead

Having seen the current situation, we now turn our attention to the future - specifically, how a shift into Group 1 could affect the deferral profile for these three issuers. Chart 2 below seeks to illustrate the potential impact.

In Chart 2, it is apparent that the deferral buckets are not impacted in a uniform fashion. This suggests the typical deferral time is expected to decrease because many trades previously categorised as ‘Large Liquid’ would be ‘Medium Liquid’ in Group 1 (and therefore subject to shorter deferral periods).

“Chart 3 shows that bonds issued directly by the European Union make up the vast majority of secondary activity for EU Sovereign Bonds. The other three issuers, with EIB the biggest, collectively contribute around 8% of volume. The increased transparency within this subset of issuers will be welcomed by those keen to see activity in a shorter time frame.”
