The problem, of course, with this data is that it is stale and very backward looking. For a much better, and up to date, indicator of what foreigners are doing with US Treasurys in near real time, the bond watchers keep track of a less known data series, called "Treasury Securities Held in Custody for Foreign Official and International Accounts" which as the name implies shows what foreigners are doing with their Treasury securities held in custody by the Fed on a weekly basis. So here it goes: in the just reported latest data, for the week ended March 12, Treasurys held in custody by the Fed dropped to $2.855 trillion: a drop of $104.5 billion. This was the biggest drop of Treasurys held by the Fed on record, i.e., foreigners were really busy selling.
