"In March, Pimco's flagship Total Return Fund (TRF) has now taken an active short position in US government debt: -3% on a Market Value basis (or $7.1 billion), and a whopping -18% on a Duration Weighted Exposure basis. And confirming just what PIMCO thinks of US-related paper is the fact that the world's largest "bond" fund now has cash, at a stunning $73 billion, or 31% of all assets, as its largest asset class on both a relative and absolute basis. We repeat: cash is more than PIMCO's holdings of Treasurys and Mortgage securities ($66 billion) combined. To paraphrase: in March PIMCO was dumping everything related to US rates (see chart below). This is the first net short position that PIMCO has had in Government-related debt since the Great Financial Crisis of 2008, and going positive in February of 2009 only after it became clear that the Fed would commence monetizing US debt one month later. This is the closest that Gross has come to making a political statement and is now without doubt putting his money where his mouth is."
