By mid-2006 real estate prices in the US began to plummet, triggering the US subprime mortgage crisis that led to a global financial crisis. German banks, too, experienced considerable loan losses and ensuing capital constraints. This was largely attributed to their various exposures to the US real estate market. In addition to their direct lending to US firms in the real estate sector and to major subprime lenders, German banks also became exposed by providing liquidity support in the form of credit lines to their asset-backed commercial paper (ABCP) conduits. For that reason, we investigate how each type of exposure in the US influenced domestic lending in Germany. We focus on the heterogeneity in the contraction taking place across banks and firms. We are mainly interested in seeing whether -when home prices started to decline in the US -differences in bank exposures to the US real estate market started to determine bank lending in Germany according to firm risk.
ContributionA number of features clearly distinguish our paper from previous work. First, having access to unique and confidential supervisory data, we know the actual time-varying exposures to the US real estate market (including direct lending to the US real estate sector and to the subprime lenders, and the indirect conduit exposure) of all German banks which, combined with the steep drop in US home prices, allows us to identify possible bank losses. Second, to identify the changes in lending we rely on credit register data that covers the entire banking sector in Germany. Finally, we examine not only the resultant aggregate volume but also the composition of bank lending in Germany across corporations, industries and regions.
ResultsWe first document the overall contraction in lending in Germany following the US home price shock. We find that banks with a higher exposure to the US real estate market contract their lending to German firms by more than banks that do not have such an exposure. The reduction in lending is more pronounced for borrowers in riskier industries and regions following a decrease in US home prices. When breaking down our estimations by type of exposure, we also find that this effect is driven by the direct exposure to the real estate sector and by the conduit exposure. In sum, we in effect document that possible losses abroad shift bank lending at home and that the size of this effect depends on the type and the degree of exposure the bank has.

AbstractWe investigate how differential exposures by German banks to the US real estate market during the recent financial crisis affect their corporate lending in Germany. Using unique bank-level exposure data, we distinguish between three different types of bank exposures, i.e. direct exposure to the US real estate sector, direct exposure to subprime lenders in the US, and indirect exposure through the liquidity provided to ABCP conduits. We find that banks with a higher exposure to the US real estate sector and to conduits cut their le...
