One example of this might be the interplay between the EU crisis management directive and the scheduled liquidity ratio requirements. This is because the draft proposals of the directive provide for short-term liabilities being excluded from bail-in, thus setting incentive for short-term funding.
This is diametrically opposed to the aim of regulating liquidity, which is to safeguard the maintenance of liquid funds even under unfavourable circumstances and for longer periods of time. Of course, a final judgement on the effects of each of the regulatory initiatives can only be made when their precise details are known and as soon as robust empirical evidence is available.
