Cryptocurrency to get G7 task force

France is creating a G7 task force to study how central banks ensure cryptocurrencies like Facebook’s Libra are governed by regulations ranging from money-laundering laws to consumer-protection rules, France’s central bank governor said on Friday.

Governor Francois Villeroy de Galhau said the task force would be led by Benoit Coeure, a European Central Bank board member.

Facebook Inc announced plans this week to introduce a new global cryptocurrency called Libra, part of an effort to expand into digital payments.

It has joined with 28 partners, including Mastercard, PayPal and Uber, to form Libra Association, a Geneva-based entity that will govern the new digital coin, according to marketing materials and interviews with executives. No banks are yet part of the group.

Facebook’s announcement drew a fast, worried reaction. The U.S. Senate Banking Committee said it would hold a hearing on the plans next month. David Marcus, who oversees Facebook’s blockchain efforts, is expected to testify, according to a source in Washington familiar with the matter.

Bank of England Governor Mark Carney said Libra had to be safe or it would not happen, and that the world’s major central banks would need to have oversight.

France, which holds the rotating presidency of the Group of Seven nations, has said it does not oppose Facebook’s creating an instrument for financial transactions. But it adamantly opposes that instrument becoming a sovereign currency.

“We want to combine being open to innovation with firmness on regulation. This is in everyone’s interest,” Villeroy told finance industry officials.

The concept of a “stable” cryptocurrency still needs to be defined, Villeroy said. In particular, what such instruments are stable against and how fixed their exchange rates are need to be determined.

Villeroy also called for a network of national anti-money-laundering authorities, coordinated by the European Banking Authority, to carry out emergency measures and even substitute for national authorities, rather than creating a specializd European agency.

Several ECB officials, including Coeure, have argued in favor of creating such an agency over the past months.
