The chief executive officer of London-based debt investor Intermediate Capital Group, Christophe Evain, has warned that investor appetite for private debt funds could wane after a big increase in fundraising in recent years.

He said: "The appetite has been strong, particularly for European funds. I wouldn't be surprised if that appetite was slowing down. The fact that the market is lot more structured and a lot of capital has been committed [means] we are likely to see a bit of a slowdown in the pace of fundraising in that area."
