Investors pulled a considerable amount of money out of bond funds in June, according to Lipper's monthly data of European fund flow trends.

Bond funds in Europe faced estimated net outflows of €17.5 billion ($20.1 billion) in June, while equity funds lost €2.5 billion over the month, according to a new report by Lipper.

As long-term mutual funds in Europe suffered net outflows of €11.1 billion, money market products lost €34.7 billion over June, according to the report. Despite the month's significant outflows from money market products, an asset class that is often referred to as a “safe haven”, money market funds recorded net inflows of €1.2 billion during the first half of 2015. 

Mixed-asset funds came out on top as the best selling asset class in June, attracting €12.1 billion, followed by real estate products (+€0.2 billion) and then commodity funds (+€0.03 billion). 

As for fund flows by markets, only six of the 34 markets covered in the report generated net inflows. Luxembourg boasted the highest net inflows in June, drawing in €7.9 billion, followed by Switzerland (€0.7 billion) and Denmark (€0.2 billion). On the other end of the spectrum, France was the single market with the highest net outflows, at â‚¬25.7 billion, followed by €10.2 billion of outflows for Ireland and €8.1 billion for Italy.

Still, the European investment industry enjoyed estimated net inflows of €296.5 billion into long-term investment funds in June. As reported by this publication, global assets under management remained steady in July at $35.9 trillion as European equities attracted $7.1 billion in net inflows, according to Lipper’s global fund market data. China's equity funds, however, suffered net outflows of $1.5 billion last month amid the struggling economy's ongoing stock market turmoil.
