""We need to make coordinated efforts at the global level to bring crypto-assets into the regulatory purview. And we need to ensure that they are subject to standards in line with those applied to the financial system. In doing so, we will have to deal with complex trade-offs, balancing the goals of promoting innovation, preserving financial stability and ensuring consumer protection. We should make faster progress if we want to ensure that crypto-assets do not trigger a lawless frenzy of risk-taking," Panetta said.
