ESMA calls for clarity on the qualification of fractional shares

The European Securities and Markets Authority (ESMA) has published a letter to the European Commission on the inconsistent regulation of trading of fractional shares across the EU. There has been an increase in the significance of fractional shares, which accounted for more than 10% of the total number of transactions reported in 2023-2024. However, shares and fractional shares are not uniformly defined under the Markets in Financial Instruments Directive (MiFID II) or the Markets in Financial Instruments Regulation (MiFIR), resulting in regulatory inconsistencies across the EU. ESMA states that while it has already taken action through its 2023 public statement to protect retail investors, uncertainty continues. The inconsistent treatment of fractional shares has the following key effects: (i) it impacts transparency and reporting requirements, (ii) it affects compliance with the MiFID systematic internaliser and share trading obligation rules; and (iii) it impacts the calculation of thresholds for data reporting services providers derogation criteria. ESMA believes consistent classification would help create a level playing field for firms and support retail participation in this market segment. ESMA suggests it would be beneficial to clarify that fractional shares, which replicate the key characteristics and trading environment of shares, should remain subject to the MiFIR rules for shares.
