The European Central Bank has published a working paper, which it notes reflects the authors’ views rather than the ECB’s, examining barriers to cross-border bank lending to firms within the euro area. The paper finds that the main obstacles to banking integration arise before lending takes place, with large frictions in cross-border bank-firm relationship formation and cross-border bank entry, while differences in loan pricing and loan quantities are comparatively small once a lending relationship exists. Using a quantitative model calibrated to euro area data, the authors estimate that a 10 percent reduction in cross-border relationship frictions would raise euro area GDP by about 1.6 percent. Drawing on AnaCredit loan-level data and RIAD group-structure data, the paper reports that cross-border lending to non-financial corporations has accounted for less than 6 percent of total euro area lending since 2019 and that cross-border bank entry remains sparse. It links the estimated barriers closely to national regulatory fragmentation using a new dataset of bilateral regulatory distances spanning macroprudential and microprudential rules, deposit insurance, resolution, supervision, entry requirements, governance and bankruptcy frameworks. The paper finds that euro area country pairs differ on roughly one quarter of these regulatory dimensions on average, and that larger regulatory differences are strongly associated with barriers to relationship formation and bank entry. In the model, the estimated output gains come mainly from broader access to financial intermediaries, lower effective financing costs, and higher capital and labor use rather than from large improvements in allocative efficiency. Gains are uneven across countries, with smaller and more financially connected economies benefiting more than larger southern economies.

European Central Bank publishes working paper linking euro area banking fragmentation to regulatory differences and estimating a 1.6 percent GDP gain from easing barriers
The European Central Bank has published a working paper, presented as the authors’ views, finding that euro area banking integration is held back mainly by barriers to cross-border bank entry and the formation of bank-firm relationships rather than by large pricing gaps. The paper links those frictions to national regulatory differences and estimates that cutting cross-border relationship barriers by 10 percent could lift euro area GDP by about 1.6 percent. Most of the gain would come from lower financing costs and higher capital and labor use.
