The letter notes that the current backdrop of strong global growth is underpinned by a resilient global financial system that is the product of determined efforts by the G20 and FSB over the past decade.
Responding to the concerns of members, the FSB has undertaken a review of the financial stability risks posed by the rapid growth of crypto-assets. Bitcoin is now trading at an average of $8,300, up 7.25 percent in the 24 hours to press time.
Yesterday, an worldwide group of central bank regulators and government ministers said that cryptocurrencies don't pose a risk to global financial stability.
In a letter published on March 18, Financial Stability Board chairman Mark Carney, who also leads the Bank of England, said that the organization doesn't see the tech as a threat - at least at this juncture.
For now, crypto-assets don't pose risks to financial stability, partly because they are still small relative to the financial system.
"Wider use and greater interconnectedness could, if it occurred without material improvements in conduct, market integrity and cyber resilience, pose financial stability risks through confidence effects", Carney wrote.
"Crypto-assets raise a host of issues around consumer and investor protection, as well as their use to shield illicit activity and for money laundering and terrorist financing", he continues in the G20 statement.
In addition, the assets aren't substitutes for currency and aren't much used for financial transactions, limiting their links to the rest of the financial system.
It concluded that, "given the global nature of these markets, further worldwide coordination is warranted".
But in a sign of too little consensus for radical action, the FSB said more worldwide coordination was needed to plug data gaps in monitoring the rapidly evolving but still tiny sector worth less than 1 percent of global GDP at its peak.
