BIS’ Carstens says cryptocurrencies “unsafe” and central banks “must be prepared to intervene”

Excerpt from lecture by Agustín Carstens, General Manager, Bank for International Settlements, Goethe University in Frankfurt, 6 February 2018

While cryptocurrencies may pretend to be currencies, they fail the basic textbook definitions. Most would agree that they do not function as a unit of account. Their volatile valuations make them unsafe to rely on as a common means of payment and a stable store of value. They also defy lessons from theory and experiences. Most importantly, given their many fragilities, cryptocurrencies are unlikely to satisfy the requirement of trust to make them sustainable forms of money.

While new technologies have the potential to improve our lives, this is not invariably the case. Thus, central banks must be prepared to intervene if needed. After all, cryptocurrencies piggyback on the institutional infrastructure that serves the wider financial system, gaining a semblance of legitimacy from their links to it. This clearly falls under central banks’ area of responsibility.  The buck stops here. But the buck also starts here.

Credible money will continue to arise from central bank decisions, taken in the light of day and in the public interest. In particular, central banks and financial authorities should pay special attention to two aspects. First, to the ties linking cryptocurrencies to real currencies, to ensure that the relationship is not parasitic. And second, to the level playing field principle. This means “same risk, same regulation”. And no exceptions allowed.
