Dec 1 (Reuters) - London Stock Exchange Group PLC (LSEG.L) Chief Executive David Schwimmer said on Thursday that large spikes in volume associated with algorithmic trading have exacerbated recent market volatility, exposing weaknesses in the global market infrastructure.
At the onset of the COVID pandemic in March 2020, some banks reached out to LSEG, asking it to close its markets for a day or two so they could catch up with post-trade processing, he said.
Another "weak spot" in global markets is in the private equity and debt markets, which have grown quickly in recent years, while using lots of leverage, but with very little transparency, he said.
"A lot of people are sort of wondering and watching, how does that play out as rates continue to go up," he said.
