Industry associations noted that part of the delay in national authorities is due to the short time gap between ESMA's release of the final technical standards in October and the implementation date.ESMA Chair Verena Ross stated, "Looking ahead, as the transition period progresses, we will continue to provide guidance and work with all national competent authorities (NCAs) to ensure the smooth implementation of MiCA and support a level playing field through regulatory convergence actions."
