Debate between Lord Bridges of Headley and Lord Bishop of Chester

Monday 6th July 2015 Lords Chamber

[Lord Bridges of Headley]

My Lords, I am certainly not complacent. The noble Lord raises a good point, and I reiterate that the Government take the matter of regulating financial markets in their entirety very seriously and closely follow developments in these markets. As I said, investment firms and trading venues should ensure that robust measures are in place to prevent automated trading creating a disorderly market and being used for abusive purposes. The new rules under MiFID II will ensure that such measures are in place.

[The Lord Bishop of Chester]

My Lords, I am a bear of little brain in relation to algo-whatever-it-is trading, and I speak as a fool. However, would this not all be solved if there was a rule that if you bought shares, you had to keep them for more than a few nanoseconds—maybe a few minutes?

[Lord Bridges of Headley]

The right reverend Prelate makes an interesting point. I refer him to the excellent Foresight report, which says that,

“liquidity, as measured by bid-ask spreads”—

I will test him on that later—

“and other metrics, has improved”.
