Barclays suffered a rocky 2020 after CEO Jes Staley stepped down following an investigation into his relationship with Jeffrey Epstein. The performance of Barclays in 2021 was stellar. The bank's investment banking segment helped it to outperform its competitors. Investment bank revenue surged by 14% year over year in the third quarter. This was caused by an increase in M&A deals and private equity buyouts. Any decrease In revenues from this segment can be made up for through the company's lending business. The interest increase from the Bank of England from 0.1% to 0.25% will certainly help things.
