Verschlusspanik (fair-SCHLOOSE-pah-neek) is a German word that literally means "closing panic." It refers to the rush of new investors (and new capital) into consumer investments like mutual funds that occurs when the sponsoring financial house announces that its fund will no longer accept new accounts beyond a certain date. That "last-minute" stampede is due to Verschlusspanik on the part of potential investors who do not want to be shut out of the fund.
"Go figure -- Fund XYZ announces that it won't open any new accounts past the end of this month, and all of a sudden there's a huge influx of new investors and their money."
"That's called 'Verschlusspanik'. It often happens when there's a deadline for new accounts imposed."
