We analyze the link between "too big to fail" (TBTF) and moral hazard using a natural experiment from an epoch of unregulated commercial banking in Denmark. In 1908 the country faced a large banking shock where the creditors of distressed commercial banks received a bailout by the government for the first time in Danish history. Due to a fortuitous combination of circumstances, banks continued to operate in an unregulated environment for more than a decade after the bailout. By considering a sample from a pre-regulation epoch, we isolate the TBTF effect. Our empirical analysis shows that TBTF banks significantly reduced post-bailout capital ratios compared to other banks.
