FRANKFURT, Germany (AP) — An international financial monitor warned world leaders Tuesday that wider use by retail shoppers of cryptocurrencies like Libra, unveiled last week by Facebook, would need "close scrutiny" by regulators.

The chief of the Financial Stability Board made the statement in a letter to the heads of state and government who will gather at the Group of 20 summit on June 28-29 in Osaka, Japan.
