You mean other than all of the past problems getting credit which forced him to seek out foreign funding in the first place? His businesses lose money and having so many bankruptcies where his partners have been left holding the bag is going to deter most bankers unless they have other ways to recoup their money.
Here’s an old report about his credit rating - note the “likely to default”:
The only bank that was lending to him, deutsche bank, literally had a board meeting and investigation to determine how he was able to bypass internal controls and get more loans after they had halted lending to him (he basically got the private wealth division to keep going after the commercial division said no more). If that is the most favorable lender left, future loans from anyone seem unlikely.
