MADRID | The Corner | The ECB doesn’t like the idea of allowing banks to use Deferred Tax Assets (DTA) to boost their capital buffers, a practice that was meant to be phased out under new European Union rules. The central lender fears that losses would be imposed on taxpayers should entities run into trouble in the coming years, as the WSJ reported. Even if the ECB doesn’t have the power to change that, and is not likely to make any move before the upcoming stress tests, it might push for DTA to be replaced by core capital.
