Elon Musk’s revived Twitter deal could lead to big losses for banks

Banks that agreed to finance Elon Musk’s takeover of Twitter faces the possibility of heavy losses now that the billionaire has reversed course and indicated a willingness to follow through on the deal, in the latest sign of trouble for debt markets crucial to financing buyouts.

The $44 billion deal, which Mr. Musk had tried to walk away from, would be paid for in part with about $13 billion in debt to seven banks, including Morgan Stanley Bank of America and Barclays PLC agreed to deliver when the takeover was sealed in April.
