Partners Group, one of Europe’s most influential investors, has raised more than $850 million for debt investments as investor appetite for private debt continues to grow.

Partners Group has raised the capital through a closed-ended private credit fund, PMCS 2014 (IV), and a handful of separate mandates for clients, according to a statement. A spokeswoman for the Swiss-based firm said about half of the total figure was raised for the closed-ended fund, which was already fully invested as of April 30 in 36 credits in Europe, the US and Asia.
