The upgrade to the trading transparency regime is one of the largest components of MiFID2. MiFID1 was very equity focused while MiFID2 has a vast scope across financial markets. The regime focuses on three areas;
- Pre-Trade – When should orders be public?
- Pre-Trade – When should quotes and expressions of interest be public?
- Post-Trade – When should executed trade details be made public?
Financial instruments are divided into asset classes, sub asset classes and sub classes and their liquidity assessed. Asset classes include bonds, interest rate derivatives while the sub classes cover areas like the maturity and underlyings of derivatives. The liquidity assessment uses several methods and some of the levels are initially more relaxed being tightened over the next few years.
More liquid products (like equity shares) will be required to make more activity public while illiquid products will have waivers to allow participants to disclose less pre trade information and to defer publication of trades executed. Generally, the rules are split between those for equity like instruments (shares, depositary receipts, ETFs, certificates) and non-equity-like (bonds, structured finance products, emission allowances and derivatives). Equity publication may be deferred one or two hours or until the end of day while non-equity-like publication may be deferred for two business days. There are also provisions for regulators to effectively suspend the whole non-equity regime for months where a liquidity crisis occurs (MiFID2 is peppered with special rules covering government debt markets).
The detailed analysis can be found here. These rules should also be viewed with the new requirements over the provision of best execution and the evidence that investment firms will need to keep to prove their compliance.
