NEW YORK, March 15 (Reuters) - Foreign investors sold a net $33.4 billion of all U.S. securities in January but remained net buyers of U.S. Treasury debt, the Treasury Department said on Monday.
January's overall outflow, which includes short-term securities such as Treasury bills, reverses a net inflow of $53.6 billion recorded in December.
Official buyers sold a record net $34.1 billion, the most since they sold $26.3 billion in September 1998, according to Treasury data.
Long-term securities saw a net inflow of $19.1 billion, though that was below December's $63.3 billion net inflow.
Overseas investors were net buyers of Treasuries to the tune of $61.4 billion, down from $69.9 billion in December.
