Our Take
US IPO activity rebounded in September 2023 from the levels seen last year at this time. Consistent with this performance, IPO activity over the past 12 months has been slightly stronger than the extremely weak activity seen during the prior 12 months. Despite this improvement, market nervousness over continued Federal Reserve tightening and the possibility of a recession in 2024, is likely to dampen U.S. IPO activity throughout the remainder of this year. We suspect this weakness is likely to keep a lid on earnings at most investment banks over the next 6 to 12 months.
Consistent with these trends, most investment banks are likely to limit their hiring of equity research analysts and salespeople for remainder of 2023. This is due to the weakness in the economy, and the limit on buy-side spending on sell-side and independent research. In fact, we suspect that the SEC’s decision to allow the SIFMA “no action” letter on hard dollar payments to US brokers to lapse, will cap buy-side payments to investment banks for their research in the latter half of this year until the EU can establish a workaround for European asset managers.
