Foreign investment in US assets fell sharply in October to the lowest level in a year.
Net inflows of capital totaled $48.1 billion in October, after an upwardly revised $67.5 billion in September, the US Treasury's International Capital report said.
That was the lowest level since October 2003, when inflows were $27.5 billion.
The report showed a lower-than-forecast level of foreign interest in US assets.
Analysts had expected the October data to show foreign inflows in the range of $50 billion to $73 billion, and one trader had said a net inflow below about $60 billion would likely be perceived as negative for the dollar.
Purchases of net domestic securities, a narrower measure that excludes transactions between US residents and foreigners in foreign stocks and bonds, dipped to $63.3 billion in October from $64.7 billion in September.
Foreigners were net buyers of US stocks in October after two months of net sales, according to the report.
They bought a net $3.8 billion in equities in October after selling a net $3.1 billion in September. Foreign appetite for US government bonds and notes increased in the month.
Foreigners bought a net $18.3 billion in October, up from $15.8 billion in September.
Market participants watch the report, informally known as the TIC data series, as a measure of foreigners' appetite for US assets, and it is of interest to the currency market amid concerns about the American current account deficit.
The October US trade gap was $55.5 billion.
