title={Banks in Tax Havens: First Evidence based on Country-by-Country Reporting},
type={Working Papers},
abstract={Since the Great Financial Crisis, several scandals have exposed a pervasive light on banks' presence in tax havens. Taking advantage of a new database, this paper provides a quantitative assessment of the importance of tax havens in international banking activity. Using comprehensive individual country-by-country reporting from the largest banks in the European Union, we provide several new insights: 1) Tax havens attract large extra banking activity beyond the regular gravity factors (+168% according to our estimates); 2) For EU banks, the main tax havens are located within Europe: Luxembourg, Isle of Man and Guernsey rank at the top of the foreign affiliates; 3) Attractive low tax rates are not sufficient to drive extra activity; 4) High quality of governance is not a driver, but banks avoid countries with weakest governance; 5) Banks also avoid the most opaque countries; 6) The tax savings for EU banks is estimated between €1 billion and €3.6 billion, i.e. 5 and 20% of fiscal revenues.},
