Foreigners were net sellers of U.S. securities in June for the first time in five months, but increased their purchases of long-term instruments such as U.S. government debt, the Treasury Department said on Monday.

Overseas investors sold a net $6.7 billion of U.S. securities in June, including short-term instruments such as Treasury bills. They were net buyers to the tune of $17.1 billion in May, according to the latest Treasury calculations.

Net long-term capital inflows, however, rose to $44.4 billion in June from a $35.3 billion inflow in May, a slight downward revision from the initial estimate.

Foreign purchases of U.S. Treasury debt rose by about $18.3 billion, though top Treasury holder China cut its stash for a second straight month.

Agency debt purchases fell by $9.2 billion, while overseas investors were net sellers of U.S. corporate debt for a second straight month.
