NEW YORK, June 7 (Reuters) - Foreign central banks were net sellers of U.S. Treasuries last week, Federal Reserve data showed on Thursday.

The Fed said its holdings of Treasury and agency debt kept for overseas central banks fell $12.5 billion in the week ended June 6, to stand at a total of $1.950 trillion.

The breakdown of custody holdings showed overseas central banks sold $9.769 billion in Treasury debt to stand at a total of $1.225 trillion.

The foreign institutions also sold securities from government-sponsored agencies like Fannie Mae (FNM.N: Quote, Profile , Research) and Freddie Mac (FRE.N: Quote, Profile , Research), subtracting $2.727 billion from their holdings, to stand at $725.21 billion.

Overseas central banks, particularly those in Asia, have been huge buyers of U.S. debt in recent years, and own over a quarter of marketable Treasuries.
