UK MiFIR meaning

What does UK MiFIR mean?
In practice, UK MiFIR is the UK onshored version of the Markets in financial instruments Regulation (Regulation (EU) No 600/2014). Practitioners use it to describe the regime governing pre- and post-trade transparency for equity and non‑equity instruments, the trading obligations for shares and derivatives, transaction reporting to the FCA, and requirements for trading venues (regulated markets, MTFs, OTFs), systematic internalisers and data reporting services providers, including the consolidated tape framework. UK MiFIR is a descriptive term rather than a defined statutory expression. It refers to Regulation (EU) 600/2014 as it forms part of UK assimilated law (formerly retained eu law) under the European Union (Withdrawal) Act 2018, as amended by the Markets in Financial Instruments (Amendment) (EU Exit) Regulations 2018 and subsequent UK instruments and FCA rules, including reforms arising from the Wholesale Markets Review and the Financial Services and Markets Act 2023. The regime applies consistently across England and Wales, Scotland and Northern Ireland, under FCA supervision. In Ireland, by contrast, “MiFIR” means the EU regulation as applied in Irish law under EU supervision; references to “UK MiFIR” in Ireland typically arise in cross‑border contexts where firms must comply with both UK and EU MiFIR requirements.

Derivatives after IP completion day: UK and EU rules on market access, CCP recognition, EMIR clearing/reporting/margin, trading, benchmarks and short selling

UK Transaction Reporting under MiFIR and RTS 22: Obligations, FCA Guidance, Operational Processes, and Reforms under FSMA 2023 (CP 25/32)

The Markets in Financial Instruments Regulation (Regulation (EU) 600/2014) (MiFIR) MiFIR established a transaction reporting framework so competent authorities can spot and probe suspected market abuse, and oversee the proper, orderly operation of markets and the business of investment firms, thereby strengthening supervision and investigatory capabilities in particular. Because MiFIR and the relevant regulatory technical standards on transaction reporting — Commission Delegated Regulation (EU) 2017/590 (RTS 22) — had direct applicability in the UK while it remained an EU member, and applied in full, they generally did not need to be transposed into domestic legislation or rulebooks to take effect in practice. At 11 pm (GMT) on 31 December 2020 (IP completion day), the Brexit transition/implementation period concluded following the UK’s exit from the EU. From IP completion day, core transitional measures ceased and major changes started to apply across the UK legal framework as a whole. Article 26 of Assimilated Regulation (EU) No 600/2014 (UK MiFIR) and Assimilated Regulation (EU) 2017/590 (UK RTS 22) were brought...

Indirect Clearing of ETDs and OTC Derivatives: UK EMIR and UK MiFIR Requirements, RTS, Segregation Options, Porting, Leapfrog Payments and Client Asset Protections

What is clearing of derivatives? Clearing is the mechanism that removes the usual danger, in practice, that one side to a derivatives deal will fail to perform (counterparty risk). The main participants involved in the clearing process are: a financial institution called a clearing house, and other financial institutions, typically banks or brokers, that enter into a clearing agreement with the clearing house—these institutions are indeed known as clearing members of the clearing house, or simply clearing firms within this framework In cleared transactions: the following applies: every trade is undertaken by clearing members, who may do so for their own accounts or for the accounts of their clients, and the clearing house inserts itself between the clearing members that entered into the trade, becoming a party to each transaction—each participant is therefore exposed to the risk of the clearing house, not to the risk of the other party Clearing members do not need...
