The fund Qatar Investment Authority (QIA) had approached financial regulators some months ago about a request for approval for a sizeable stake in Germany's largest lender, the people said. But Qatari officials haven't yet provided the necessary documentation, which could derail QIA's investment plans.
It remains unclear whether QIA has lost interest or if it is taking its time. Qatar initially expressed interest in the stake well before Deutsche Bank announced on March 17 that it was in talks to merge with Commerzbank. The issue is sensitive because the European Central Bank may ask Deutsche to raise fresh funds to approve any deal.
