“Market transparency” has to do with the amount of information about the market that is available to market participants. Broadly speaking, “market transparency” can be broken down into two categories:
- pre-trade transparency - refers to information about the prices at which trades can be executed- i.e. the bid and offer prices and sizes (also known as volumes) in which market participants are willing to trade. Pre-trade prices can be indicative or firm.
- post-trade transparency - refers to information about the prices and volumes of trades that have already taken place.
The amount of pre-trade and post-trade transparency available to market participants can vary significantly from market to market, both in terms of:
- the kind of information is available – there tends to be greater transparency in retail markets than in wholesale markets. Additionally, some markets such as equity markets tend to have much greater levels of both pre- and post-trade transparency than other markets such as bond markets and over the counter (“OTC”) derivative markets.
- how frequently it is made available - information can be made available on a real-time basis (i.e. it updates as dealing interest changes) or it can be made available on a delayed basis (i.e. some time after the trade has been executed).
ICMA discussion paper on Transparency and liquidity in the European bond markets29 September 2020 The state of liquidity in the European bond markets has been hotly debated for a number of years, with the growing realization that due to a culmination of factors market liquidity has been in serial decline for more than a decade. There is an ongoing parallel discussion on the issue of transparency in the European bond markets. While it is broadly recognized that a degree of price transparency is fundamental for market efficiency and integrity, the intersection of transparency and liquidity is a far more complex consideration, yet an important one from the perspective of market development.
ICMA has been at the forefront of industry work related to both bond market liquidity and the design and implementation of the European transparency framework for bonds. This paper attempts to pull those two workstreams together in order to explain how bond market structure and dynamics are very different to those of equity markets, that this is the basis for how liquidity is created in bond markets, and why this is central to any considerations around the framework for European bond market transparency, including any proposed future regulation related to the provision and design of a consolidated tape for bonds.
