That would be a logical next step in the progression. And another way for Riad to monetize his fake bonds. Especially because he can hide them behind "credit-lined".
Even if they are not, because the CDFT scheme collapsed, I would not be surprised if that was the intent. We all know these scams are planned and scripted long in advance. The CDFT collapse may have altered the scheme, but clearly mucking around with fake bonds is the playbook.
