Banking groups have become increasingly multinational but the institutional infrastructure to deal with solvency or liquidity problems is still largely national. This might lead to financial instability if national authorities do not internalise externalities abroad. Recently ex-ante burden sharing agreements have been established (e.g. EFSF), but little empirical work has been done on potential costs and benefits of such agreements. We estimate the costs and benefits of financial stability support for large, internationally active banks under several proposed agreements. We show costs according to the ‘national solution’, where only home authorities inject capital, as our benchmark. ‘Specific’ sharing agreements would be redistributive at the expense of smaller and East European countries (not home to large cross-border banking groups). The ‘general fund’ mechanism will smooth costs across countries but may lead to unequal redistribution of costs. We also show that coordinating bank failure costs may bring about financial stability benefits.
