- Abstract
- This box explores the potential macroeconomic impact of different capital buffer replenishment paths. Model simulations show that replenishing capital buffers too early or too aggressively could be counterproductive and prolong the economic downturn. While the costs of restoring capital buffers to pre-crisis levels are not excessive if the economy moves along the central projection scenario, a weaker economic environment would increase bank losses and result in a more extensive use of capital buffers. In such a scenario, a later and more gradual restoration of capital buffers would be warranted.

- Abstract
- Could a monetary policy loosening entail the opposite effect than the intended expansionary impact in a low interest rate environment? We demonstrate that the risk of hitting the rate at which the effect reverses depends on the capitalization of the banking sector by using a non-linear macroeconomic model calibrated to the euro area economy. The framework suggests that the reversal interest rate is located in negative territory of around −1% per annum. The possibility of the reversal interest rate creates a novel motive for macroprudential policy. We show that macroprudential policy in the form of a countercyclical capital buffer, which prescribes the build-up of buffers in good times, can mitigate substantially the probability of encountering the reversal rate, improves welfare and reduces economic fluctuations. This new motive emphasizes also the strategic complementarities between monetary policy and macroprudential policy.

- Abstract
- Had authorities built up larger countercyclical buffers before the pandemic, it would have been easier to release capital in response to the crisis. The “lower for longer” interest rate environment reinforces the case for building up releasable buffers in good times. The article shows that enhancing countercyclical capacity can improve the policy mix available to achieve macro-financial stabilisation.
