It's not preferable, but all major U.S. financial companies will eventually be under government control because the alternative is so much worse, Hugh Hendry, chief investment officer at hedge fund Eclectica Asset Management, said Friday.

"All financials will be owned by the U.S. government in a year," Hendry said. "I bet you."

Nationalizations take dramatic losses from the private sector and places them on the larger balance sheet of the public sector, he said.

"It's not good," but society is vulnerable and society is going to have to intervene, Hendry said.
