In terms of growth rates, annual growth would be 0.03 percentage points (or 3 basis points) below its baseline level during this time. This is then followed by a recovery in GDP towards the baseline growth path. The estimated maximum GDP impact per percentage point of higher capital is 0.17% during these 35 quarters.
This trade off between growth and financial stability is considered to be affordable. The reason why Basel III is to be implemented over a long period (January 1, 2013 to December 31, 2018) is to minimise the impact on growth and the simulations seem to support the time frame for implementation.
