JPMorgan Chase & Co. can’t transfer a loan obligation of Grupo Televisa SA’s cable unit to a bank controlled by billionaire Carlos Slim, a federal judge said.

A federal judge in New York in February initially halted the transfer after Empresas Cablevision SA complained that assigning the loan to Slim’s Banco Inbursa SA might reveal Cablevision’s confidential information to a rival cable company owned by Slim.
