Banks could be stuck with $13 billion in debt as a result of the Musk deal.

People familiar with the matter told The Wall Street Journal that the debt won't be sold immediately to avoid huge losses.

The banks could sell it at a higher price if they chose to do so.

Billions of debt lenders were stuck with after the 2008 financial crisis, so it could be the biggest stalling deal ever.

The banks agreed to lend money to Musk earlier this year, before investors were found.

According to The Journal, rising interest rates and a looming recession planted seeds of doubt that didn't help the process.

Musk has until October 28 to close the deal or he will go to court in November.

Sources told the newspaper that banks hope to sell some of the debt in early 2023 if the deal closes. A person told the Journal that the debt could be divided to make it easier to sell.

The banks did not respond to Insider's request for comment.

Musk's takeover has caused a lot of concern. There were reports that the world's richest man planned to cut 75% of his workforce, but the company denied that.

President Joe Biden could kill the acquisition if the US government reviews it.
