Using regulatory data, we study German bank lending in countries targeted by financial sanctions. We find that domestic banks in Germany reduce lending in sanctioned countries, whereas their foreign bank affiliates outside Germany increase lending. In some cases, this is because the bank affiliates’ host countries have not imposed sanctions themselves. However, even German bank affiliates in host countries that enact sanctions like Germany increase lending if these host countries lack strong institutions and anticrime policies. These findings suggest that even universally adopted sanctions distort bank capital flows and competition if the level of their enforcement varies across bank locations.

Affiliates of multinationals borrow a considerable amount from their parent company, even when the parent is located in a high-tax country. This is at odds with standard theories of a tax-efficient capital structure. We set up a model that analyzes the functioning of the internal capital market and investigates the trade-off between tax savings and capital market frictions within the group. We test the model on data of the universe of German multinationals. The empirical analysis largely supports our model in that: (i) smaller multinationals often rely on parental debt financing; (ii) larger multinationals are more likely to use internal banks; (iii) parental debt and external debt are substitutes and the mix depends on the relative cost of raising capital through the parent and the affiliates; (iv) local and within-group tax incentives play an important role in determining all three types of debt.
