The US equity capital markets are facing a backlog of $40bn (€26.3bn) worth of issues that have been waiting to float over the last six months, as rocky credit markets continue to delay potential listings.

The backlog includes deals that are pending and issues that have been postponed over the last 180 days. Due to the admission rules of the US Securities and Exchange Commission, the data is only available for the US market, according to investment banking research company Dealogic.
