"We understand that big ideas take time, that policymakers and others are raising important questions, and that we can't do this alone," Marcus said in a letter to Senate Banking Committee Chairman Mike Crapo (R-ID) and Sen.

"We want, and need, governments, central banks, regulators, non-profits, and other stakeholders at the table and value all of the feedback we have received."
