The world's financial leaders will call on international standard-setting bodies March 20 for stronger monitoring of cryptocurrencies and related assets and to assess the need for a multilateral response as such assets could at some point threaten financial stability.

The call appears in a draft communique prepared for the meeting of finance ministers and central bank governors of the world's leading rich and developing nations in Buenos Aires on March 19-20.

The G-20 financial leaders will say the technological innovation behind cryptocurrencies has the potential to improve the efficiency and inclusiveness of the financial system.
