Liquidity in some metrics such as open interest and volumes has since improved as volatility has reduced, however our extensive market intelligence conversations suggest that many still believe there is further to go when looking ‘under-the-bonnet’ at another key metric, market depth.

But there are some signs that the sensitivity has increased over the past year in the UK.
