Crain Communications weekly Financial Week writes "T-fund trouble", which discusses fee waivers and near-zero yields on Treasury money market funds. "The rush to Treasuries has caused enormous pressure on yields, said Peter G. Crane, founder of Crane Data." FW quotes Crane, "I think the knee-jerk reaction is, 'Get me into Treasuries'.... And then people are looking at the actual yields, and they must be wincing."
The article says, "As of the end of February, Treasury institutional money market fund assets stood at $248 billion, a 243% increase over the previous year, according to Crane Data. Over the same period, prime institutional money fund assets grew just 42%, to $939 billion."
