In our Business Plan 2020/21, we noted that we track the proportions of trades carried out on venues with varying levels of trade disclosure.
This follows key reforms introduced through MiFID II including increased trade transparency which have changed the trading landscape. As the graph below shows:
- The UK’s market structure offers different levels of trade transparency to meet the varying execution needs of market participants.
- The structure of the market was relatively stable during the year, which includes a period which markets were impacted by the coronavirus crisis. While trading on auctions, systematic internalisers, and dark trading were all active during this time, lit venues saw the biggest increase, as participants sought certainty of execution.

Liquidity in different markets may vary over time for many reasons. While we do not aim to promote any particular level of liquidity, levels of liquidity are something we monitor. In our Business Plan 2020/21, we undertook to report on summary data on liquidity. However, this is not an outcome measure.
In normal conditions, trade volume is one indicator of an asset’s level of liquidity. As shown in the graph below, turnover in UK equities and liquid, investment grade, sterling-denominated corporate bonds was relatively stable from mid-2020 to mid-2021. With the end of the EU transition period at end-2020, we can see slight declines in trading volumes for both equities and bonds around the period. Trading volumes subsequently returned to previously observed levels shortly after.
