Deutsche Bank is considering selling shares to boost capital later this year, the German lender’s latest attempt to resolve concerns about its financial strength, according to people familiar with the matter.

The potential capital hike, which Deutsche Bank executives haven't yet decided whether to pursue, would be on top of €1 billion to €2 billion ($1.38 billion to $2.77 billion) of capital-boosting hybrid bonds that it plans to issue in coming weeks, these people said.
