Investment Banking in the UK Industry Data and Analysis
Companies in the Investment Banking industry provide financial advisory services, offering their insight on IPOs, M&As and equity and debt security underwriting activity. Competition has been fierce in recent years, with a flood of boutique firms entering the industry as bankers look for healthier rewards than those offered by the more regulated larger investment banks. Growing M&A and IPO activity before 2022-23 ramped up demand for investment banking services, although this momentum lost speed in 2022-23 as access to cheap capital ended.
